ABSTRACT

 

Yousif AA, Al Mashadani KM., Prevalence of clinical and subclinical mastitis in ewes with Staphylococcus aureus, Onl J Vet Res., 24 (7):383-387, 2020. We report prevalence of mastitis and staphylococcus aureus in 100 lactating ewes in Baghdad, Iraq. Milk samples (n=194) were subjected to California mastitis test (CMT), somatic cell count (SCC) and S aureus antibiotics. By clinical examination we found 6 ewes but 12 milk samples with mastitis (~6.8%) with 33% S. aureus. By CMT 28 apparently normal milk (subclinical mastitis) samples tested positive (~27%) of which 9 had S. aureus. By SCC 27 ewes tested positive with more than 500,000 cells/ml all with S. Aureus. S. aureus were highly sensitive to cefotaxime (100%), Erythromycine (100%), Ciprofloxacin (100%) but less to Amikacin (94.1%), Ceftriaxone (88.2%), Oxacillin (88.2%) or Cephalexin (76.4%). Our results suggest that somatic cell counts over 500,000 may differentiate subclinical from clinical mastitis in ewes.

Key words: Mastitis , Staphylococcus, Antibiotic sensitivity test Staphylococcus aureus.
