“…One of the most accepted techniques in epidemiological studies is bacteriophage typing. Although there are different typing sets, S. aureus from bovine mastitis has mainly been characterized by using the human international set of phages according to the technique of Blair and Williams (1961), (Wallace et al, 1962;Frost, 1967;Laevens et al, 1996). Other phenotypic characterization includes haemolytic activity, biochemical and enzymatic reactions, including activity on selective media, and antibiotic susceptibility patterns (Frost, 1967;Matsunaga et al, 1993;Aarestrup et al, 1995a;Laevens et al, 1996).…”

A study of the characterization of the phenotypic patterns of Staphylococcus aureus strains isolated from bovine subclinical mastitis in Israeli dairy herds and their correlation with the severity of the disease was undertaken. A total of 400 chronically S. aureus-infected Israeli-Holstein cows, from 15 dairy herds were included in this study. Based on the results of the biochemical reactions, of the anti-biogram and phage typing, one major type of S. aureus was determined in each herd, its prevalence being between 54 and 100% of the total isolates from that same herd. The majority of the isolates were found to be non-haemolytic (62.7%). The most common phage type was 3/A,3/C,55,71, which was predominant in five herds. In two herds none of the isolates (24) were typable by this set of phages. All isolates were susceptible to methicillin, erythromycin, cephalotin, norfloxacin, trimethoprin-sulphamethoxazole and novobiocin. Most isolates were resistant to penicillin (96.6%) and 52% to oxytetracyclin. Differences in protein patterns between 50 and 36 kDa were found by one-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis. No correlation between any combination of the phenotypic characteristics was found when correlation was done with milk yield and somatic cell count, corresponding to the 6 months before sampling. Otherwise, a positive correlation was found between type of haemolysis and the N-acetyl-beta-glucosaminidase (NAGase) values. In milk from quarters infected with the-non-haemolytic strains, the level of NAGase was significantly lower (P < 0.05) than that from quarters infected with the haemolytic strains (69.7 and 105.9, respectively). However, the level of NAGase activity in the milk of the quarters infected with the non-haemolytic strains was significantly higher (P < 0.05) when compared to the milk of quarters infected with coagulase-negative staphylococci (43.5).

“…The public health significance of staphylococci isolated from milk and dairy products is important. It has been suggested that cattle can be a source of antibiotic-resistant strains for humans (30), with a possible interchange of staphylococci strains between humans and animals (33). Phage typing and antibiotic sensitivity have been used in attempts to determine the origin of strains and to investigate the importance of antibiotic-resistant strains.…”

A total of 57 gram-positive, catalase-positive cocci, considered etiological agents of clinical and subclinical bovine mastitis, were tested for glucose and mannitol fermentation, coagulase and thermonuclease production, sensitivity to lysostaphin, gelatin hydrolysis, lysozyme, phosphatase and egg yolk factor production, hemolytic properties, antibiotic sensitivity, susceptibility to human and bovine phages, and enterotoxin production. All 57 strains were identified as staphylococci. A good correlation was found between 3+ and 4+ coagulase reactions, thermonuclease production, and high sensitivity to lysostaphin. Neither mannitol fermentation nor production of other enzymes appeared to be a specific property of bovine Staphylococcus aureus strains. beta- and delta-hemolysins were more frequently found than alpha-hemolysin. Nearly 40% of the strains were penicillin resistant. Strains were lysed by phage 42E from the human phage set more frequently than by phage 42D, whereas with the bovine set, strains were more sensitive to specific bovine phages. Three strains produced enterotoxin C, and one strain produced enterotoxin D.

“…In addition, human attendants can harbour Staph. aureus phage 80/81 complex with possible transfer to animals (Wallace et al 1962). Thus the carriage by the strains of epidemic-associated phages and agglutinogens described by Poole & Baker (1966), Cohen (1972, Oeding (1978), Krynski & Becla (1981) may be capable of causing similar conditions reported by these authors.…”
