This study evaluated infection by vector-borne agents in 58 crab-eating fox (Cerdocyon thous L.) that were road-killed in an Atlantic rainforest reserve in the state of Espírito Santo, southeastern Brazil. Spleen, lung, or blood samples collected from the foxes were tested in the laboratory by a battery of polymerase chain reaction (PCR) assays targeting bacteria of the genera Rickettsia, Borrelia, Coxiella, Anaplasma, and Ehrlichia; and protozoa of the genera Babesia, Hepatozoon, and Leishmania. Of the targeted organisms, evidence of infection in the foxes was detected for Ehrlichia and Hepatozoon organisms only. Overall, six (10.3%) foxes were infected by an ehrlichial agent closely related to an ehrlichial agent recently detected in free-ranging Jaguars [(Panthera onca (L.)] in central-western Brazil, and to Ehrlichia ruminantium. For Hepatozoon, 28 (48.3%) foxes were infected by an agent closely related to Hepatozoon sp. Curupira 2 and H. americanum; and one (1.7%) fox was infected by an organism closely related to reptile-associated Hepatozoon agents. Finally, 11 (19.0%) foxes were found infested by Amblyomma cajennense (F.) nymphs, which were all PCR negative for the range of vector-borne agents cited above. Because the haplotypes found in free-ranging foxes are genetically closely related to pathogens of great veterinary importance, namely E. ruminantium and H. americanum, it is highly desirable to know if these novel organisms have any important role as agents of diseases in domestic animals and wildlife in Brazil.

Protothecosis is a severe, emerging opportunistic infection caused by the saprophytic, achlorophyllous microalgae of the genus Prototheca. Though uncommon, human and animal cases are increasing worldwide, making awareness of this fungal-like pathogen important in both human and veterinary medicine. We report a fatal case of disseminated protothecosis caused by P.

Article Synopsis
- Tick-borne pathogens (TBPs) in dogs pose a significant global health threat, particularly in developing countries where surveillance is lacking.
- A study involving 230 community dogs in Nepal found that 32.6% were infected with at least one TBP, with common pathogens including Ehrlichia canis and Anaplasma platys.
- The findings suggest that infections in community dogs might pose a risk for transmission to pet dogs and humans, highlighting the need for increased awareness and control measures against these zoonotic parasites.

Although vector-borne agents have been detected in different species of wild animals, studies involving tapirs (Tapirus terrestris), the largest land mammals in Brazil, are scarce. The aim of the present study was to investigate the occurrence and molecular identity of Anaplasmataceae agents, Coxiella burnetii and Hepatozoon spp. in blood samples of wild T.

The increasing population of dogs and changes in the climatic conditions have resulted in the emergence and re-emergence of vector-borne diseases in canines. These vectors borne diseases in canines pose a diagnostic challenge to the field veterinarians because of co-infections with several pathogens. Comprehensive data on the prevalence of haemoparasites and haemorickettsiales in pet and community owned dogs from south India are scant.

Article Synopsis
- Vector-borne diseases pose significant health challenges due to their complex control and zoonotic nature, especially in tropical regions where vector activity is year-round.
- In Guadeloupe, a study analyzed blood samples from 46 outdoor dogs across five veterinary clinics to identify the presence of canine vector-borne pathogens, revealing that 30.4% of the dogs were infected.
- The most common pathogens found were Coxiella burnetii (17.4%) and Dirofilaria immitis (8.7%), while there were no infections from other commonly tested pathogens, highlighting a knowledge gap in vector-borne diseases in the Caribbean.
