Dog owners are greatly concerned about tick infestations in their pets. The prevalence and dispersion of ticks and their disease-causing microorganisms have been limited from the viewpoint of dog owners in Vietnam. This study investigated the presence of tick infestation and the pathogens associated with it in canines that were brought to veterinary hospitals in Vietnam. In the survey, 1,423 dogs participated from February to October 2022. Molecular and morphological methods were utilized to identify ticks and the associated pathogens. In addition,risk variables linked to tick infestation were documented and analyzed using statistical methods. The total exposure to the brown dog tick (Rhipicephalus sanguineus sensu lato) was 29.01%. Nam Dinh has the highest tick prevalence among the research areas. Tick infestation reached its highest point between June and September in the northern region of the country, with distinct seasons showing a strong correlation with tick infestation in dogs. Out of 177 tick pools examined, 146(82.49%) tested positive for at least one infection. Mycoplasma spp. (78.53%) was the most common, followed by Anaplasma spp. (37.29%), Rickettsia felis (5.08%), Babesia vogeli, and Hepatozoon canis (2.82%). In the current study, there was a statistically significant link between tick infestation and characteristics such as age, breed, body size, lifestyle, and bathing frequency. Understanding the seasonal behavior of vector ticks is crucial for identifying individuals or animals susceptible to tick-borne diseases. Studying the distribution of ticks and their ability to carry and disseminate zoonotic germs in specific places could assist veterinarians and policymakers in implementing effective strategies to manage zoonotic infections.

Background and Aim: Camels are a unique source of milk and meat, which helps recover from several diseases that affect humans worldwide. In Egypt, one of the great obstacles for this industry is tick-borne diseases. This study aimed to characterize blood parasite infections, such as Babesia (B.) bovis and Trypanosoma (T.) spp. in one-humped camel (Camelus dromedarius) (n=142) breeds in Halayeb and Shalateen, Egypt, through phylogenetic analysis. Materials and methods: The prevalence of B. bovis and Trypanosoma spp. was identified in camels using polymerase chain reaction (PCR) assays targeting the Rhoptry-Associated Protein-1 and internal transcribed spacer 1 genes, respectively. A nested PCR technique was conducted to detect B. bovis. At the same time, KIN multispecies PCR assay was employed to diagnose and classify trypanosome DNA in camels. Results: B. bovis was detected in 4/142 camels with an infection rate of 2.81%. Sequencing and phylogenetic analyses revealed that the strain of B. bovis isolated from this population was closely related to strains isolated from Argentine, the United States, and Brazil. Moreover, Trypanosoma evansi was detected in 8/142 camels with an infection rate of 5.63%. Sequencing and phylogenetic analyses revealed that this isolated strain T. evansi was closely related to Trypanosoma theileri detected from cattle in Brazil. Conclusion: The obtained data indicated the existence of B. bovis and T. evansi in camels from two provinces of Egypt. The obtained findings have economic significance and reflect the importance of implementing effective prevention and control methods across Egypt to reduce the incidence of B. bovis and T. evansi in camels.
