Onchocerca gutturosa and Onchocerca lienalis in cattle: Variation in length of microfilariae by site of recovery

American Journal of Veterinary Research, 1989
SUMMARY Dermal microfilariae recovered from specimens obtained from umbilical and cervical sites of cattle infected with adult Onchocerca gutturosa alone or with adults of O gutturosa and O lienalis were measured and compared with uterine microfilariae obtained directly from gravid female worms of each species. Uterine microfilariae of O gutturosa were

Immunohistological studies on Onchocerca volvulus paramyosin

Parasitology Research, 2009
Paramyosin is a muscular protein exclusively found in invertebrate species, which has been proposed as a vaccine candidate against infections with Schistosoma mansoni and Brugia malayi. Here, we report the studies on the distribution of Onchocerca volvulus paramyosin, designated OvPmy, in different O.

Biopsy of Onchocerca Nodules in the Igbos of Nigeria

The American Journal of Tropical Medicine and Hygiene, 1975
The occurrence of Onchocerca nodules in the Igbos of Nigeria was studied in a biopsy series. There were 90 cases in approximately 5,000 biopsies received in 4.5 years at a central laboratory. The prevalence of infection in males was 1.5 times that of females. The two youngest patients were both aged 3 years; the oldest was approximately 70 years.
