“…High prevalence of ETEC strains expressing F5 and F41 fimbrial adhesions was described in Spain (Garabal et al 1997) and Sweden (Soderlind et al 1988). On the other hand, strains expressing F5 and F41 adherence antigens were isolated rarely in the United Kingdom (Wray et al 1993) and in Poland (Osek and Truszczynsky 1992) which is in agreement with our results (F5positive were recorded only in four cases, i.e. 2.5 %) and none of the isolates coded for F41 alone.…”

One-hundred sixty Escherichia coli isolates obtained from piglets with diarrhea from different parts of Slovakia were examined for the presence of genes coding for F4, F5, F6 and F41 fimbrial adhesins, and hemolytic activity. According to polymerase chain reaction tests 74 (46%) E. coli isolates were positive for primers that detected genes coding for fimbrial adhesins. Of these 74 isolates, 64 were positive for genes encoding for F4+, four for F5+, five for F6+, and one for both F41+ and F5+ adhesins.

“…The comparative approach allowed the identification of possible predisposing factors, which are important in lowering the prevalence and reducing the number of outbreaks of enteric pathogens associated with diarrhoea in piglets. The epidemiological situation with regard to the investigated pathogens in Poland was studied decades ago; thus, there is a need for an update as to the current situation (Osek and Truszczyński 1992, Osek 1999). …”

Prevalence and factors associated with the occurrence of bacterial enteropathogens in suckling piglets in farrow‐to‐finish herds

The aim of the study was to determine both environmental and infectious factors, influencing occurrence of bacterial enteropathogens in suckling piglets. For this purpose, a cross-sectional study in 70 Polish farrow-to-finish pig herds was performed. In each herd, presence of selected intestinal pathogens (Escherichia coli, Clostridium perfringens and Salmonella species) in faeces of suckling piglets were determined using bacteriological and PCR methods. Using logistic regression models, risk factors for enterotoxigenic E coli with fimbriae F4 (ETEC-F4) and C perfringens type A were established. Prevalence of bacterial enteropathogens in investigated herds was as follows (on herd and sample level): ETEC-F4 30.0 per cent and 9.3 per cent, respectively, C perfringens type A 91.4 per cent and 58.3 per cent, C perfringens type C 1.4 per cent and 0.3 per cent, Salmonella species 2.9 per cent and 0.5 per cent. The occurrence of ETEC-F4 was associated with presence of diarrhoea in piglets and vulval discharge in sows. Vulval discharge in sows, not slatted floor in farrowing pen and lack of coccidiosis prevention were determined as risk factors for C perfringens type A. The results obtained in the study revealed the high prevalence of enteropathogenic bacteria in pig herds and indicate management and organisation of production as factors having the greatest impact on the incidence of bacterial enteropathogens in piglets before weaning.

“…Different research groups established that isolates positive for STb were also positive for other enterotoxins. The most prevalent enterotoxin gene combination observed was LT-STb Wilson & Francis, 1986 ;Nagy et al, 1990 ;Hare1 et al,,, 1991 ;Osek & Truszczynski, 1992). Studies of the association of STb wj th adhesion factors and with strain serotype were also conducted (Table 1).…”
