The bacterium Treponema pallidum pertenue causes yaws in humans and nonhuman primates. We describe 33% T. pallidum pertenue seropositivity in 9 species of nonhuman primates in Uganda and Rwanda, seroconversion during a lethal outbreak and a novel bacterial genomic lineage. Yaws may threaten both public health and conservation in the region.

Taenia crassiceps (Zeder, 1800), a zoonotic cestode with a wide geographical distribution, utilises canids as definitive hosts and small rodents as intermediate hosts. However, accidental infections in non-human primates, particularly in captive lemurs, have been increasingly documented. In this case report, we describe the first documented case of cysticercosis caused by the larval stage of T.

Clinical microbiology involves the detection and differentiation of primarily bacteria, viruses, parasites and fungi in patients with infections. Billions of people may be colonised by one or more species of common luminal intestinal parasitic protists (CLIPPs) that are often detected in clinical microbiology laboratories; still, our knowledge on these organisms' impact on global health is very limited. The genera Blastocystis, Dientamoeba, Entamoeba, Endolimax and Iodamoeba comprise CLIPPs species, the life cycles of which, as opposed to single-celled pathogenic intestinal parasites (e.

Zona pellucida glycoprotein-1 (ZP1) is essential for maintaining oocyte structural integrity and facilitating fertilization. Mutations in are strongly associated with primary infertility disorders such as fertilization failure and empty follicle syndrome; however, the absence of accurate experimental models has hindered mechanistic understanding and obscured the etiological basis of -related infertility. In this study, CRISPR/Cas9-mediated genome editing was employed to generate two -edited cynomolgus macaques ( ), designated #ZP1-1 (male) and #ZP1-2 (female).

Comparative psychologists have been criticized for using a limited number of species in drawing general conclusions about broad behavioral processes. There are numerous examples, however, of the inclusion by behavior analysts of atypical subjects in their research. To examine the frequency and diversity in subject species used in the experimental analysis of behavior (EAB), JEAB publications between 1958 and 2023 were reviewed for their use of subjects other than pigeons, rats, humans, and nonhuman primates.
