Epidemiology of Ovine Campylobacter Infection Determined by Numerical Analysis of Electrophoretic Protein Profiles

Abstract

The relationship of 50 Campylobacter strains isolated from aborted ovine foetuses, and the faeces of sheep, cattle and chickens were determined by numerical analysis of electrophoretic (SDS-PAGE) protein profiles. Comparison of protein patterns by numerical methods revealed differences between C. fetus ssp. fetus, C. jejuni, and C. coli strains as well as heterogeneity among isolates from different outbreaks. Isolates from each farm produced a distinct cluster and flocks from different locations were found to be infected with relatively different strains. In most cases, protein patterns of ovine foetal isolates were very similar to those of ovine faecal isolates. Ovine isolates of C. fetus ssp. fetus, C. jejuni and C. coli gave similar protein patterns to the corresponding Campylobacter species isolated from cattle or chicken, on the same farm. Thus, it was concluded that certain protein types of ovine Campylobacter strains were more likely associated with local areas, and Campylobacter strains causing ovine abortions are distributed in the environment more widely than assumed to date.

Campylobacter isolation from the feces of sheep with a history of reproductive disorders bred in the state of São Paulo, Brazil

“…As similar strains are capable of causing abortions in poultry and cattle, these animals are also considered reservoirs of Campylobacter spp. (DIKER et al, 2000). The presence of birds on sheep farms increases the risk of lambs becoming infected in their first days of life (BROMAN et al, 2002;PAO et al, 2014).…”

Development and stability of bacteriocin resistance in Campylobacter spp.

“…Campylobacter spp. are considered to be commensal organisms in the intestinal tracts of wild and domestic animals including chickens and other avian species (Diker et al 2000). Epidemiological studies demonstrated that consumption of contaminated poultry meat is the major cause of human campylobacteriosis (Stern et al 2001(Stern et al , 2004.…”

“…Campylobacter türleri, çeşitli evcil ve yabani hayvanların normal bağırsak florasında bulunmakta ve bu hayvanlarda enterik infeksiyonlar ve genital sistem infeksiyonlarına neden olmaktadır (7,8,13,17). Termofilik Campylobacter'ler grubunda incelenen Campylobacter jejuni, C. coli ve C. lari türleri, dünyanın pek çok böl-gesinde insan ve hayvanlarda bakteriyel enterik infeksiyonların en sık rastlanan nedenleri arasında yer almaktadır (3,14,16).…”
