“…The results of the biotyping tests performed on the isolates obtained in this study confirm earlier observations (Devriese et al, 1972) on the distinct characteristics of S. aureus strains originating from poultry. The strains differ sufficiently from human strains to make the possibility unlikely that chicks acquire their staphylococcal flora from human sources soon after hatching, as has been suggested by Harry (1967a).…”

Important populations of Staphylococcus aureus were found to be present on the body surfaces of live poultry originating from flocks without history of staphylococcal disease. Their sized increased considerably until approximately the seventh week of life after which time they were maintained at equally high levels. Significant correlations were found between the populations recovered from superficial wash samples and skin-tissue samples. Similarly the numbers isolated from the nasal cavities were correlated with other surface counts. Low numbers were present in the intestinal tract. Birds with staphylococcal synovitis had higher numbers in all sampling regions. The counts were very high in subjects suffering from staphylococcal dermatitis. Higher rates of positive birds and higher numbers of staphylococci were detected with a whole body sampling method than with a nasal swab technique. The isolates obtained in this study belonged to the S. aureus biotype B which is associated with poultry and pigs.

“…aureus associated with disease in poultry and found that the phage typing results were unlike those in a collection of human strains, confirmed by Hajek & MarShlek (1971), and that strains on the skin and in the upper respiratory tract were similar to those present in infected lesions. Devriese et al (1972Devriese et al ( , 1975 extended these findings and showed that their poultry strains of Staph. aureus, which increased in numbers on the live birds up to the seventh week of life, belonged to biotype B (Hajek & Margalek 1971, 1973.…”

About half (49%) of strains of Staphylococcus aureus isolated from poultry were non‐typable with the international human set of phages, and 55% were biotype B according to the biochemical identification scheme of Hájek & Maršálek (1971, 1973). A furthest neighbour clustering strategy and principal coordinate analysis based on 17 biochemical tests made clear distinctions between biotype B strains and a group of biotype A and intermediate strains. Overall 62% of strains were enterotoxigenic, the majority producing enterotoxin A. Significantly fewer intermediate strains than biotype A or B strains were enterotoxigenic. Starch gel zymograms of intracellular esterases showed a general correlation with the biotyping and phage typing results.

Staphylococcus aureus isolates recovered from poultry between 1970 and 1972 (90 old isolates) and in 2006 (81 recent isolates) were screened for the presence of bap, icaA and icaD genes associated with biofilm formation, and for bbp, cna, ebpS, eno, fib, fnbA, fnbB, clfA and clfB genes that encode microbial surface components recognizing adhesive matrix molecules (MSCRAMMs). Most of the old isolates were collected from broiler breeders affected by staphylococcal tenosynovitis and arthritis, whilst nearly all recent isolates were derived from the nose and cloaca of healthy broilers. Ten recent isolates belonged to the animalassociated methicillin-resistant S. aureus (MRSA) ST398. All isolates were positive for clfA, clfB, eno and fnbA, and were negative for bap and bbp. All recent isolates were also positive for ebpS and cna, and all old isolates were positive for fib. The average number of genes encoding adhesins and biofilm-associated proteins in both groups was eight per isolate. All MRSA ST398 isolates in this study were positive for icaD, cna, ebpS, eno, fnbA, fnbB, clfA and clfB. No relevant differences were found between the presence of adhesin and biofilm formation genes in old and recent S. aureus isolates or in isolates from healthy compared with diseased chickens. From this study, there is no indication that the presence of these genes has changed over time and no specific association could be found between the presence of certain MSCRAMM or biofilm genes in poultry S. aureus isolates and the isolate's capacity to cause disease.
