Opis:: To compare the genotypes of Campylobacter jejuni, isolates of cattle origin were collected from 9 Polish farms and genotyped by ERIC-PCR. We identified 28 genotypes among the 43 C. jejuni isolates, and demonstrated high genomic diversity. The highest level of diversity was observed in strains isolated from stanchion-barn animals in opposition to those from the loose-housing system.

Opis:: Eighty enterococcal isolates (E. faecium, n=38, E. faecalis, n=42) from diseased farm animals (swine, cattle, poultry) in Lithuania have been studied for the prevalence of antibiotic resistance and for resistance and virulence genetic determinants. 86% of E. faecium and 71% of E. faecalis isolates were multidrug resistant (resistant to three or more unrelated antibiotics). Resistance to aminoglycosides, tetracycline and erythromycin was found most frequently in both species (61%, 69%) and was linked to aph(3’)-IIIa, aac(6’)-Ie-aph(2”)-Ia, ant(6)-Ia (aminoglycoside resistance), tetM, tetL (tetracycline resistance), ermA, ermB (erythromycin resistance) gene combinations, which were supplemented with chloramphenicol resistance genes catA7, catA8 (E. faecalis) and catA9 (E. faecium). All E. faecalis isolates harboured genes coding for virulence factors agg, esp, fsr gelE alone or in combinations with the high prevalence of esp gene in isolates from cattle (63%) and pigs (79%). The origin- dependent incidence of agg gene variants prgB and asp1 was observed. The results indicate the existence of a large pool of potentially virulent and multidrug resistant E. faecalis in diseased farm animals posing risk to humans.

Opis:: The increasing interest in enzymatic growth promoters prompted this investigation of the effect of an enzymatic stimulating complex on selected hematological and serum biochemical parameters in boars. The enzymatic complex [five proteases (proteinases-endopeptidases) and two peptidases (exopeptidases) obtained by fermentation from Streptomyces fradiae] was added to diets for three months, at initial doses of 90 (group El) and 120 (group E2) g/ton feed for the first seven days followed by 40 and 60 g/ton, respectively, in the subsequent weeks. The evaluation was based on selected hematological (RBC, WBC, HCT (Ht), HGB (Hb), MCV, MCH, and MCHC) and biochemical (AST, ALT, AP, Ca, Mg, urea, cholesterol, creatinine, inorganic phosphorus, and oxyglucose) parameters determined before and after the experimental period. The reported values were within physiological norms. Statistical differences were found between experimental groups with respect to WBC, HCT (Ht), MCV, MCH, AP, Ca, Mg, creatinine, and inorganic phosphorus. The study results indicate that the complex of proteolytic enzymes administered to boars caused no negative changes in their metabolic profiles. The statistically different hematological and serum biochemical parameters, while within normal limits, point to an early stage of microcytic anemia and heightened agitation that could be the result of intensified nitrogen metabolism.
