an outbreak of ringworm in karakul sheep caused by a physiological variant of trichophyton verrucosum outbreak of ringworm in karakul sheep occurred during 1973 among the flocks of at least 14 farmers in south west africa and the northern cape province. infections spread from one farm to another as a result of introducing infected stud rams. on one farm a few cattle, a goat and a horse developed lesions after being in contact with infected sheep. some of the attendants handling infected sheep also contracted the disease. strains recovered from infected animals resembled trichophyton verrucosu ...19751187096
development and evaluation of real-time pcr assays for the quantitative detection of babesia caballi and theileria equi infections in horses from south africa.a quantitative real-time polymerase chain reaction (qpcr) assay using a taqman minor groove binder (mgb) probe was developed for the detection of babesia caballi infection in equids from south africa. nine previously published sequences of the v4 hypervariable region of the b. caballi 18s rrna gene were used to design primers and probes to target unique, conserved regions. the b. caballi taqman mgb qpcr assay was shown to be efficient and specific. the detection limit, defined as the concentrati ...201020031328
pathology and immunohistochemistry of papillomavirus-associated cutaneous lesions in cape mountain zebra, giraffe, sable antelope and african buffalo in south lesions associated with papillomaviruses have been reported in many animal species and man. bovine papillomavirus (bvp) affects mainly the epidermis, but also the dermis in several species including bovine, the best-known example being equine sarcoid, which is associated with bvp types 1 and 2. this publication describes and illustrates the macroscopic and histological appearance of bpv-associated papillomatous, fibropapillomatous or sarcoid-like lesions in cape mountain zebra (equus zebra ...201122135923
