Abstract

Salmonella spp. has been recognized as the major cause of food-borne illness in humans worldwidecausing remain relevant to public health. Poultry vaccination is one promising strategy to mitigateSalmonella infection in poultry and, in turn, in humans as well. The objective of this study was to assessthe potential of cross-reaction of serum in Salmonella enteritidis-vaccinated chicken to some serotype ofSalmonella enterica. Four female, Isa Brown layer chickens (20 weeks old), were vaccinated with S. enteritidisstrain Sm24/Rif12/Ssq (intra vena) to induced the production of specific antibodies in serum. Crossreactionof serum in S. enteritidis-vaccinated chicken were assess with agar gel immunodiffusion test(AGID) with S. enteritidis, S. pullorum, S. typhimurium, S. typhi, and Escherichia coli antigens. Serumcould react with S. enteritidis and all types of S enterica used in this study (S. pullorum, S. typhimurium,S. typhi), but could not react with E. coli. The potential of cross-reaction of serum in S. enteritidis-vaccinatedchicken to some serotypes of S. enterica may play a role in reducing the infection caused by that serotype.

Abstract

Staphylococcus aureus is known as a major causative agent of mastitis in dairy cattle. In the presentstudy, 104 isolates of Staphylococcus originated from subclinical mastitis cattle characterized for thephenotypic properties and the presence of Staphylococcal protein A (Spa). Some bacteria were resistancesagainst several antibiotics were also studied, such as erythromycin, streptomycin, tetracycline, cefepime,nitrofurantoin, amikacin, chloramphenicol, and ciprofloxacin. About 78% of the isolated were moderatelysensitive to nitrofurantoin, while 89% were highly resistant to cefepime and ciprofloxacin. Using thevarious mammals? sera, seven isolates out of 104 revealed the presence of Spa.
