| Abstract: | Examination of milk from goats yielded 41 strains from 40 clinically affected halves; 15 were Staphylococcus aureus, 6 Staph. epidermis, 1 Streptococcus agalactiae, 2 Strept. dysgalactiae, 5 Strept. uberis, 2 Corynebacterium pyogenes, 3 Escherichia coli, 3 Pasteurella spp. and 4 Mycoplasma spp. One half had dual infection of Staph. aureus and Strept. dysgalactiae. Twenty two of the 297 milk samples from apparently normal halves also harboured pathogens comprising of 9 Staph. aureus, 1 Strept. agalactiae, 2 E. coli, 2 Pasteurella spp., 2 Candida albicans and 6 Mycoplasma spp. Most of the bacterial isolates were sensitive to many broad spectrum antibiotics. Twenty of the 24 Staph. aureus isolates were phase typable by a set of 23 human Staphylococcal International Phages suggesting the utility of these phages for the typing of goat strains. The isolates were grouped into 15 phage-types, many of which have been reported from human infections in Iraq. This indicates the possibility of association of human strains of Staph. aureus in caprine mastitis. No definite correlation could be noted between antibiogram and phage types of Staph. aureus strains. |
