Abstract
- This study was conducted at the livestock/wildlife interface areas of national parks and traditional cattle grazing areas. The main aim of the study was to establish the occurrence of Escherichia coli serogroups isolated from Kafue lechwe antelopes (Kobus leche kafuensis) and pastoral cattle. A total of 593 faecal samples from lechwe (232) and pastoral cattle (361) were conveniently picked from the grazing pastures in the interface areas and cultured for E. coli. From each faecal sample, two or three presumptive E. coli isolates were picked to constitute 1,283 isolates with 574 from lechwe and 708 from cattle. Some of these isolates were found to be similar to Shiga toxin-producing E. coli O157 on CHROMagar and sorbitol MacConkey agar. Only 18 E. coli isolates from Kafue lechwe antelopes were grouped into eight serogroups while 32 from pastoral cattle were grouped into 16 serogroups. The most prevalent type-able serogroups from lechwe antelopes and pastoral cattle were O125 (5.8%) and O29 (4.2%), respectively. On further analysis by fermentation of various sugars, some isolates showed a similar pattern suggesting that the strains were indistinguishable. Key words: Escherichia coli, diarrheagenic, Shiga toxin, Kobus leche kafuensis, pastoral cattle.
