Topic Information

Dear Colleagues,

The TTP conferences have historically convened leading experts and researchers worldwide, focusing on ticks and tick-borne pathogens. This eleventh edition promises to be no different, offering a platform to showcase groundbreaking research, innovative methodologies, and promising discoveries in various facets of tick biology. These encompass tick physiology, microbiome and genomics, taxonomy and the evolution of ticks and tick-borne pathogens, their ecological and epidemiological aspects, pathogenesis, diagnosis, and strategies for control, including immunity and vaccines.

For more information regarding the TTP11 Conference and opportunities to present your research, please visit https://agropecuaria.cigb.edu.cu/ttp11/ or https://zooparaz.net/ttp11/. Furthermore, we invite you to contribute to a Topic in renowned MDPI journals such as Pathogens, Animals, Vaccines, Veterinary Sciences, Arthropoda and Insects.

This Topic offers researchers the chance to publish enhanced and refined versions of their conference contributions, thus extending the impact of their work far beyond the event itself. This proposal represents a valuable opportunity to advance the dissemination of cutting-edge research and foster collaboration within the tick research community—an essential step towards advancing the field. Moreover, this Topic will be a lasting repository of the collective knowledge and insights shared during TTP11. We eagerly anticipate receiving your contributions.

Here, we described the prevalence of Borrelia burgdorferi s.l. and Babesia species found in mono- and double infections among Ixodes ricinus ticks occurring in urban areas of the city of Poznań, Poland. We tested 1029 host-seeking ticks and 1268 engorged ticks removed from pet animals. Borrelia afzelii and B. garinii prevailed both in ticks from vegetation (3.7% and 3.7%, respectively) and from pets (3.7% and 0.6%, respectively). Babesia canis and Ba. microti were the most prevalent in host-seeking (2.6% and 1.4%, respectively) and feeding ticks (2.8% and 2.2%, respectively). Babesia microti sequences proved to be identical to the human pathogenic Ba. microti genotype “Jena/Germany”. Sequences of the rarest piroplasm Ba. venatorum (0.7%) were identical with those isolated from European patients. About 1.0% of tested ticks yielded dual infections; in host-seeking ticks, Ba. canis prevailed in co-infections with B. afzelii and B. garinii, whereas Ba. microti and B. afzelii dominated in double-infected feeding ticks. Dual infections, even with a low prevalence, pose a challenge for differential diagnosis in patients with acute febrile disease after a tick bite. The finding of Ba. canis in both tick groups suggests that I. ricinus could be involved in the circulation of this piroplasm. Full article

Bovine babesiosis, caused by the protozoan Babesia bigemina, is one of the most important hemoparasite diseases of cattle in Mexico and the world. An attenuated B. bigemina strain maintained under in vitro culture conditions has been used as a live attenuated vaccine; however, the biological mechanisms involved in attenuation are unknown. The objective of this study was to identify, through a comparative transcriptomics approach, the components of the B. bigemina virulent parasites that are differentially expressed in vivo, as opposed to those expressed by B. bigemina attenuated vaccine parasites when inoculated into naïve cattle. The biological material under study was obtained by inoculating spleen-intact cattle with infected erythrocytes containing either the attenuated strain or a virulent field strain. After RNA extraction, transcriptomic analysis (RNA-seq) was performed, followed by bioinformatic Differential Expression (DE) analysis and Gene Ontology (GO) term enrichment. The high-throughput sequencing results obtained by analyzing three biological replicates for each parasite strain ranged from 9,504,000 to 9,656,000, and 13,400,000 to 15,750,000 reads for the B. bigemina attenuated and virulent strains, respectively. At least 519 differentially expressed genes were identified in the analyzed strains. In addition, GO analysis revealed both similarities and differences across the three categories: cellular components, biological processes, and molecular functions. The attenuated strain of B. bigemina derived from in vitro culture presents global transcriptomic changes when compared to the virulent strain. Moreover, the obtained data provide insights into the potential molecular mechanisms associated with the attenuation or pathogenicity of each analyzed strain, offering molecular markers that might be associated with virulence or potential vaccine candidates.

Background: Tick-borne encephalitis (TBE) is a disease with mandatory declaration in the EU since 2012. Information regarding the seroprevalence of the disease across Romania is limited, and only sporadic cases are rarely reported. We aimed to identify new areas of TBEV infection in different counties of Romania. Methods: We conducted a serosurvey assessing the immune response to TBEV infection in adult populations from rural areas in different counties of the country. Seropositivity was defined by a positive TBEV IgM/IgG ELISA test and confirmed by serum neutralization. Results: We collected 1116 samples from 15 different localities in 10 counties (divided into endemic/border/non-endemic counties) across Romania. Overall, 26 (2.3%) of the samples were tested positive using the TBEV ELISA assay in six counties. In those counties, 3.7% of sera were positive, varying from 1.4% to 6.9% per county. After performing the neutralization assay, seven (0.6%) samples were confirmed positive, interestingly all from one site in Sibiu County, where the seroprevalence was 9.7%. Conclusions: The identification of positive serum samples in serosurveys appears to rely on the discovery of TBEV microfoci. Further serological surveys should be conducted in Romania, especially after the identification of positive TBEV patients presenting for medical care. Full article

Spotted fever group Rickettsia spp. (SFGR) are a large group of tick-borne bacteria causing important emerging and re-emerging diseases that affect animals and humans. While SFGR are found worldwide, a lack of surveillance and misdiagnosis particularly affect South American countries. Colombia is a high burdened country in South America, yet rickettsioses are not deemed a nationally reportable condition limiting disease-specific public health resources. As mortality rates are high for one Rickettsia pathogen species, there is a great need to better understand the epidemiological and ecological factors that increase SFGR transmission risk regionally. This literature review provides an overview of Colombia-based SFGR studies connecting knowledge about both vectors and hosts. Full article
