“…Erlichia canis is an obligate intracellular Gramnegative α-proteobacterium that infects leukocytes and causes the canine monocytic ehrlichiosis, a potentially zoonotic disease that affects dogs and is transmitted by Rhipicephalus sanguineus bites (218). E. canis was detected by blood PCR in one of 19 healthy free-ranging marmosets (108). Interestingly, the genotype of the E. canis sequenced from this marmoset was very similar to other genotypes identified in domestic dogs, indicating the overlap of habitats between these animals.…”

Neotropical primates are represented by more than 200 species and subspecies distributed in five families. Considering that some of these species are considered endangered, disease investigation in these populations is critical for conservation strategies. Therefore, an increasing number of studies and publications on this topic became available in the past few years. This review deals with infectious diseases of neotropical primates, with focus on free-ranging animals, including those caused by bacterial, viral, protozoal, metazoan, or mycotic infectious organisms, with particular emphasis on gross and microscopic lesions associated with these diseases. In addition, a few relevant unpublished cases of infection by Staphylococcus spp., Streptococcus spp., E. coli and Pseudomonas spp. were included in this review.

“…While researching marmosets living in urban and forest areas, Verona (2008) [43] verified the presence of bacteria such as Escherichia coli (which may cause gastroenteritis, urinary infection, and meningitis in humans), Klebisiela oxytoca (causes infections in the urinary tract, and septicemia), Klebsiela pneumoniae (pneumonia), Sphingomonas paucimobilis (may cause peritonitis, cerebral abcesses, cervical adenopathy, respiratory infections, urinary infections, and meningitis) and Salmonella enteriditis (gastroenteritis). Aside from microfilaria, fungi, parasite eggs and nematode larva [43,49].…”

Survey of ticks and tick-borne pathogens in wild chimpanzee habitat in Western Uganda

et al. 2023

Background Ticks and tick-borne pathogens significantly impact both human and animal health and therefore are of major concern to the scientific community. Knowledge of tick-borne pathogens is crucial for prescription of mitigation measures. In Africa, much research on ticks has focused on domestic animals. Little is known about ticks and their pathogens in wild habitats and wild animals like the endangered chimpanzee, our closest relative. Methods In this study, we collected ticks in the forested habitat of a community of 100 chimpanzees living in Kibale National Park, Western Uganda, and assessed how their presence and abundance are influenced by environmental factors. We used non-invasive methods of flagging the vegetation and visual search of ticks both on human team members and in chimpanzee nests. We identified adult and nymph ticks through morphological features. Molecular techniques were used to detect and identify tick-borne piroplasmids and bacterial pathogens. Results A total of 470 ticks were collected, which led to the identification of seven tick species: Haemaphysalis parmata (68.77%), Amblyomma tholloni (20.70%), Ixodes rasus sensu lato (7.37%), Rhipicephalus dux (1.40%), Haemaphysalis punctaleachi (0.70%), Ixodes muniensis (0.70%) and Amblyomma paulopunctatum (0.35%). The presence of ticks, irrespective of species, was influenced by temperature and type of vegetation but not by relative humidity. Molecular detection revealed the presence of at least six genera of tick-borne pathogens (Babesia, Theileria, Borrelia, Cryptoplasma, Ehrlichia and Rickettsia). The Afrotopical tick Amblyomma tholloni found in one chimpanzee nest was infected by Rickettsia sp. Conclusions In conclusion, this study presented ticks and tick-borne pathogens in a Ugandan wildlife habitat whose potential effects on animal health remain to be elucidated. Graphical Abstract
