In this work, Microsoft Bing chat with GPT-4 was used for researching the antibiotic use of clays by submitting three requests that were literally the following: (+) write a bullet list of the most important points concerning research on the use of clay minerals for preparing antibiotics; (+) write a bullet list of suggestions for future and original research, not performed before, on the use of clay minerals for preparing antibiotics; (+) write a bullet list of the most important results of clinical trials of clay minerals as antibiotics. Bing’s answers were extensive, containing information on mineralogical and health issues. Bing also suggested follow-up questions, some of which were also included, and that expanded the topics considered to domains of ethics and arguably even politics, with repeated references to “respecting the traditional knowledge and practices of indigenous or local communities that have used clay minerals for medicinal purposes for centuries”, including the answer to the following question suggested by Bing, “How can we improve the antibiotic activity and specificity of clay minerals?”.

Significant risk of side effects of drug therapy in newborns, especially in premature neonates, is associated with immaturity of a number of enzyme systems and biotransformation mechanisms and pharmacokinetic specificity. We consider the use of thiotriazoline), a drug licensed in Ukraine with proven hepatoprotective and cardioprotective activity and a high safety profile, for premature infants to reduce side effects of antibiotic therapy. The use of thiotriazoline in antibiotic therapy results in an increase in the concentration of eNOS in blood plasma and a decrease in alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase and bilirubin in blood plasma. These results provide experimental support for the use of thiotriazoline to reduce the side effects of azithromycin therapy in newborns. Full article

The rising issue of antibiotic resistance has emerged as a serious global health problem, compromising our capacity to successfully tackle bacterial diseases. Antibiotic abuse and misuse have hastened the development of resistance, leaving many once-effective medications useless. This research investigates ways for reversing antibiotic resistance, with a special emphasis on rejuvenating older drugs. Several main techniques are being investigated in the attempt to “Make Old Antibiotics Great Again.” First, we investigate the mechanisms behind antibiotic resistance, offering information on the evolutionary processes that drive bacterial adaptability. Following that, we will look at the possibilities of antibiotic combination treatment, a strategy that can improve the efficacy of older antibiotics by utilising synergistic drug interactions. Furthermore, we investigate the potential of antibiotic stewardship programmes, stressing the ethical use of antibiotics to lessen selection pressure for resistant bacteria. Rapid molecular testing, for example, is highlighted as a vital tool for accurate antibiotic selection, improving treatment regimens, and limiting resistance development. The importance of research and development activities in the quest to discover new antibiotics is underlined, as it provides a long-term solution to the resistance challenge. Furthermore, we discuss the importance of policy interventions and global cooperation in creating the landscape of antibiotic resistance, eventually recommending a united response to this critical issue. In summary, this study underlines the need to reverse antibiotic resistance, emphasises the potential of older antibiotics when used wisely, and recommends a holistic strategy incorporating scientific, medical, and policy strategies to address this emerging danger to public health.

Bandages, gauzes, and alcoholic pads have been widely used for wound healing. However, bacterial infection in wounds is still a major problem and needs to be explored. Apart from antibacterial activity, the hydrophilicity of a membrane is also a major characteristic of membranes that should be explored. Upon contact with wound exudates, the hydrophilic membranes absorb water, swell, and liquefy to form a gel over the wound, which enhances autolytic debridement. Keeping this in view, this study aimed to synthesize and optimize a Polyvinyl Alcohol (PVA) and Gum Tragacanth (GT) membrane having different concentrations of gold nanoparticles (AuNPs) loaded with Ciprofloxacin (CIP) and their effect on the hydrophilicity of the membranes. CIP-AuNPs were prepared by the Turkevich method, and then for confirmation FTIR was performed. Membranes with different concentrations of CIP-AuNPs incorporated in PVA/GT and analyzed for their hydrophilicity. A membrane swelling ratio test as well as contact angle analysis were performed. Through this study, it was concluded that hydrophilic membrane of PVA/GT having a 5% concentration of CIP-AuNPs can be used as a wound healing material. Full article

Background: Staphylococcus aureus, particularly methicillin-resistant S. aureus (MRSA), has emerged as a leading antimicrobial-resistant pathogen challenging global health systems and antibiotic therapy. Pigs have been identified as important reservoirs for livestock-associated MRSA. The major concern with MRSA occurrence in pigs is the potential for human transmission. Reports on the prevalence and antibiotic sensitivity pattern of methicillin-susceptible S. aureus (MSSA) and MRSA strains in pigs in Nigeria are still limited, hence, the need for this study. This study was designed to investigate the prevalence of MRSA and methicillin-sensitive Staphylococcus aureus in pig farms in Ibadan, Oyo State, Nigeria, and to determine their antibiotic resistance patterns. Methods: We collected 93 composites (n = 5; total n = 465) of faecal samples from pigs in twenty-five farms across five local government areas in Ibadan, Nigeria. Isolation of S. aureus was conducted using standard procedures. Antibiotic sensitivity testing was conducted using the disc diffusion method. The data obtained were analysed using descriptive statistics and compared with the CLSI and EUCAST standards for sensitivity and resistance. Results: The prevalence of S. aureus was 31.2%, with the proportion of MSSA and MRSA isolates being 23.7% and 7.5%, respectively. The antibiotic susceptibility profiles revealed a high multidrug resistance prevalence among both MSSA (86.4%) and MRSA (100%). All MRSA isolates and 40.9% (9/22) of MSSA were found to be resistant to at least five different sub-classes of antibiotics. Conclusions: This study supports the existing reports on pigs being an important reservoir of highly resistant S. aureus strains. The high multidrug resistance and the occurrence of MRSA may be evidence of continuous antimicrobial exposure and substandard hygienic practices on these farms. This is undesirable because it constitutes a health hazard for farmers, veterinarians, abattoir workers, and pork consumers, who may further disseminate these highly resistant strains to their families and society. There is a need for further surveillance and a multisectoral approach involving policymakers, farmers, health practitioners, and the public in implementing good infection control practices and safe antibiotic usage from the grassroots level on farms in line with the vision of the one health approach.

This study investigated the resistotyping of Salmonella spp. and Staphylococcus aureus from milk and milk products sold in Sabon Gari and Zaria local government areas in Kaduna State, Nigeria. A total of 122 isolates (Salmonella spp. (65) and Staphylococcus aureus (57)) were isolated from 400 milk and milk products. The isolates were subjected to antimicrobial susceptibility testing using the disc diffusion and E-test methods. The results obtained from the study indicated that 39 (31.967%) isolates were sensitive to all tested antibiotics, while 47 (38.525%) were resistant to a single antibiotic. Furthermore, 36 (29.508%) were resistant to two antibiotics, and none showed resistance to at least three antibiotics. None showed resistance to all four antibiotics. Resistance rates were most frequently observed in tetracycline with 80 isolates (65.574%), followed by ampicillin with 39 isolates (31.967%), and gentamicin and ciprofloxacin, both with 00 (00.000%) isolates. After making comparisons with the CLSI and EUCAST breakpoints, the resistance rate with CLSI was observed in tetracycline with 104 isolates (85.245%), followed by ampicillin with 39 isolates (66.393%), ciprofloxacin with 14 isolates (11.475%), and gentamicin with 06 isolates (04.918%). The resistance rate with EUCAST was tetracycline with 122 isolates (100.000%), followed by ampicillin with 110 isolates (90.164%), ciprofloxacin with 88 isolates (72.131%), and gentamicin with 17 isolates (13.934%). Based on these findings, it can be shown that Salmonella spp. and Staphylococcus aureus found in milk and milk products within Sabon Gari and Zaria local government areas have a high resistance to the antibiotics tested. It is imperative that urgent actions are taken to address the growing menace of AMR and prevent the spread of antibiotic-resistant pathogens. Full article

Community-acquired pneumonia (CAP) is a common acute infection associated with significant morbidity and mortality, particularly in older adults with significant comorbidities. For this reason, an empirical treatment protocol for CAP was developed in a social–health care hospital. The aim of the study was to evaluate compliance with this protocol. Methods: a descriptive, retrospective study of all patients admitted to our hospital and diagnosed with CAP from September to December 2022 was conducted. Demographic variables: age, sex; pharmacological variables: empirical antibiotic treatment according to protocol, change of antibiotic treatments, mean duration of treatment, compliance with criteria and performance of sequential therapy on the third day and after the third day. Results: 55 patients were included (mean age, 88.9 years (64–103), 58.2% men). A total of 50.9% received empirical antibiotic treatment according to the protocol. The empirical antibiotics prescribed were amoxicillin/clavulanate (25.5%), ceftriaxone + levofloxacin(23.6%), piperacillin/tazobactam (18.2%), ceftriaxone (14.5%), levofloxacin (7.3%), meropenem(5.5%), ertapenem (1.8%), imipenem (1.8%) and levofloxacin + azithromyzine (1.8%).Change of antibiotics occurred in 27.3%, and the mean duration of treatment was 8.3 days. Sequential therapy: 56.4% met the criteria on day 3, but this was only among 19.3%. Of the remaining patients, 22.45% were switched to oral in an average of 6 days. Conclusion: compliance with the empirical treatment protocol in CAP occurred in a very low percentage of patients. Moreover, in patients who met the criteria for sequential therapy, it was performed after the third day. Therefore, with the aim of improving these results, new measures and activities have been proposed. Full article

Antimicrobial resistance (AMR) has been recorded as a fast-growing One Health challenge globally. The major driver of AMR is the inappropriate use of antibiotics in humans and animals. A substantial volume of antimicrobials is consumed by the animal industry for the treatment of Escherichia coli (E. coli) infections, which is a challenge; therefore, the understanding of AMR in animals is critical in solving this rising One Health problem. This study assessed the resistance level of some critically important antibiotics to E. coli bacteria isolates from cattle fecal samples. A total of twenty-eight composite (n = 5) fecal samples were collected from farms in four different Local Government Areas (LGAs) within Ibadan: Akinyele LGA:7, Ibadan north LGA:12, Ido LGA:4, and Lagelu LGA:5. Standard microbiological methods were used for isolation, antibiotic sensitivity tests (ASTs), and ESBL production. A total of 22 (78.6%) E. coli isolates were recovered, and the results showed resistance to critically important antibiotics in ascending order; streptomycin (0.00%), meropenem (0.00%), gentamicin (4.55%), ceftazidime (18.8%), sulphamethazole (22.73%), cefotaxime (54.55%), ampicillin (63.64%), pefloxacin (81.82%), and amoxicillin–clavulanate (100%). Of the 22 positive E. coli isolates, 8 (36.4%) were ESBL-producing and 17 (60.7%) were multidrug-resistant. ESBL enzymes share the ability to hydrolyze third-generation Cephalosporin, and this makes ESBL-producing E. coli exhibit resistance to antibiotics (especially Cephalosporins). The results show the possibility of AMR becoming a looming pandemic globally. The presence of multidrug-resistant ESBL-producing E. coli in cattle in Ibadan was established. Resistance to third-generation Cephalosporin antibiotics is of public health significance. Ensuring antimicrobial stewardship and prescription-based medication, alternative therapies to antibiotics, and the adoption of a collaborative approach are measures to preventing an AMR pandemic.

Candida species are considered as common flora of the healthy human mycobiome and occur on skin, mucosal surfaces of gastrointestinal and genitourinary tracks. Pathogenic Candida spp., reported to cause skin, vaginal and oral infections. Extensive use of antifungal agents has increased the drug resistance among pathogenic strains of Candida. To this effect, recently naturally occurring AMPs and synthetically modified peptides, are effectively being used as promising antifungal agents. Short peptides display better permeability to cross the yeast membrane, thus short antifungal peptide were designed using sequences from APD database. Natural peptides are potential source of antifungal agents. Considering above facts, we studied anticandidal potential of synthetic and natural peptides. Full article

Self-medication (SM) of antibiotics has become a prevalent reason for the development of antibiotic resistance. This study aims to assess the use of self-medication practices with antibiotics and related factors among the population of Ernakulam district, Kerala. Sore throat (34%) and cough (26%) are found to be the major reasons for the self-usage of antibiotics among people. Various antibiotics commonly used for self-medication were amoxicillin, ciprofloxacin, and azithromycin. Reasons for the use of antibiotic self-medication were previous successful experiences (7.7%), convenience (11.5%), and to save costs (3.8%). Improper antibiotic use may lead to drug overuse and thereby antibiotic resistance. Hence, it should be taken only under strict supervision by an expert. Full article

Antibiotic prophylaxis is used to prevent infections related to surgery from the administration of antimicrobials before, during and after the procedure. Its practice is mainly recommended in surgeries classified as contaminated or potentially contaminated. Its use should also be considered in clean surgeries in which the occurrence of infections brings serious consequences, such as mastectomy and mammoplasty. Thus, the present study aims to discuss the use of antibiotic prophylaxis in mammoplasty and mastectomy surgeries. This is a narrative literature review, in which the Health Sciences Descriptors (DeCS) “mammoplasty”, “mastectomy” and “antibiotic prophylaxis” were used to search the MedLine and LILACS databases, included in the Virtual Library in Health (BVS). It was observed that the occurrence of infections after mammoplasties or mastectomies can cause damage, such as delay in recovery, in adjuvant therapy, and loss of the reconstructed breast or impaired cosmesis, when applicable, which corroborates the use of antibiotic prophylaxis in these procedures. Patients are screened for methicillin-resistant (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA). The main antibiotics used in prophylaxis were cephalosporins (cefazolin, cefadroxil and cefuroxime), isoxazolylpenicillins (flucloxacillin), aminoglycosides (gentamicin) and glycopeptides (vancomycin) in associations. In the studies found, antimicrobial prophylaxis proved to be promising, therefore, the research ratified the importance of using antibiotic prophylaxis in mammoplasty and mastectomy surgeries to prevent infections, also associated with adequate skin preparation practices, with 2% chlorhexidine and 70% isopropyl alcohol.

According to the 2021 European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) report on sales of veterinary antimicrobial agents, the data collected for the 2010–2021 period points to a significative sales reduction in over 2/3 of the countries included. Until now, a reduction in consumption to an average value of 96.6 mg/PCU was achieved in a premise that the average value of 59.2 mg/PCU can be reached by 2030, urging new political strategies for the next years. However, when exploring data from countries individually for the same decade, several shortcomings in data collection are noticed. In fact, mandatory data reporting was not on equal ground between countries, with different data aggregation strategies used and several countries in multiple years recognizing underreporting values. Access to similar tools and methodologies for data collection is crucial for all European members, especially to collect and report consistent, correct, and uniform data. Simultaneously, some gaps are observed in the PCU unit system, excluding some animals such as livestock goats and pets, and being unclear in others like in aquaculture, requiring revision to help it implement the “One Health” approach. Preventive or mitigation actions require a standardized data system allowing trustworthy conclusions and projections. Platforms like the ESVAC database are interesting tools which can be improved and replicated, allowing for the analysis of the different elements of the “One Health” approach such as human and environmental data, as well as data about resistance to antimicrobial agents.

Background: This study aimed to assess the antimicrobial resistance profiles of urinary tract infection (UTI) collected from individuals of various age groups, both male and female. Methods: This study analyzed 266 urine samples from diverse individuals. Midstream urine samples were collected, transported, and processed on a CLED medium within two hours. Bacterial identification was performed based on colony morphology, Gram staining, and biochemical characteristics. The VITEK 2 Compact system (Biomerieux, Marcy-l’Étoile, France) was used for antimicrobial susceptibility testing, ESBL detection, and Carbapenemase detection. Results: Out of 61 significant UTIs in both the male and female patients, 78.69% were caused by Gram-negative bacteria, 11.48% were caused by Gram-positive bacteria, and 9.84% were caused by Candida species. Escherichia coli (37.70%), Klebsiella pneumoniae (26.22%), and Pseudomonas aeruginosa (11.47%) were the most common uropathogens. Tetracycline (88.89%) and ceftriaxone (77.14%) were met with high resistance, while amikacin (89.36%) and colistin (97.30%) were the most effective against both Gram-negative and Gram-positive uropathogens. Colistin susceptibility was exclusively observed in cases of multidrug resistance (MDR) and pan-drug resistance (PDR). Conclusions: This study indicates that Gram-negative bacteria, particularly E. coli, are responsible for a higher number of UTIs compared to Gram-positive uropathogens. Amikacin and colistin were identified as the most effective antibiotics against both Gram-negative and Gram-positive uropathogens. Full article

The proliferation of enterobacteria that produce extended spectrum β-lactamases (ESBLs) has become an important public health concern. The objective of this work was to optimize a phenotypic method for straightforward and rapid ESBL detection in strains obtained from food environments, employing MALDI-TOF mass spectrometry. A collection of 162 enterobacterial isolates, including ESBL producers, AmpC producers, ESBL-AmpC coproducers and sensitive strains was analyzed using a quick method based on cefotaxime hydrolysis. Statistical analysis showed that although the presence of constitutive AmpC hyperproducers could reduce its specificity, this MALDI-TOF assay is an excellent tool for quickly classifying ESBL-producing strains of foodborne Enterobacteriaceae.

In recent years, bacterial infections have become a major global concern, causing significant morbidity and mortality. Unfortunately, the development and commercialization of new antibacterial drugs have been slow, while pathogens continue to rapidly adapt and evolve. To address this challenge, nanotechnology offers a promising strategy by protecting, targeting, and releasing active compounds to fight against these emerging strains. The aim of this study was to explore the antibacterial potential of nanoemulsions (NEs), as reported in the scientific literature. A literature review was carried out utilizing the keywords “nanoemulsion”, “antibiotic activity”, “antibacterial activity”, and “antimicrobial activity”. All of the scientific articles that were related to the area of health and published in the last 5 years were included. All of the studies indicated that oil-based NEs with inherent antibacterial activity, even without the presence of drugs, had superior action against strains compared to non-emulsified oil, as well as other systems incorporating drugs or actives. Although the results are promising, further investigations and testing of formulations against resistant bacterial strains are necessary. This review aims to provide valuable insights for researchers and contribute to future advancements in this field. Full article

The world of antibiotics is undergoing a significant transformation, driven by the dual challenges of antimicrobial resistance and ecological ramifications associated with their use. This thesis provides a comprehensive examination of the intricate relationship between antibiotics, public health, and the environment, shedding light on the multifaceted problems that this interplay creates. The research scrutinizes the global crisis of antibiotic resistance, investigating its origins, underlying mechanisms, and its alarming proliferation. Antibiotic-resistant bacteria pose a serious threat to the effectiveness of these crucial drugs in the fight against infectious diseases. This necessitates a re-evaluation of antibiotic use and the development of innovative strategies to curb resistance, while also focusing on the ecological consequences of antibiotic utilization. While antibiotics are designed to target specific pathogens, their impact extends to the broader microbial communities they encounter. This research delves into the effects of antibiotics on ecosystem balance, with a particular emphasis on their contribution to the growing problem of environmental antibiotic resistance. This thesis offers a holistic perspective on the evolving landscape of antibiotics through a comprehensive analysis of these interconnected aspects. It emphasizes the urgent need for a global response to address resistance, advocates for a balanced approach to antibiotic usage, and underscores the pivotal role of public health strategies in managing these intricate challenges.
