Mastitis is diseases of dairy cows with a high economic impact. Bovine mastitis caused by wide range bacterial pathogens. As one the major environmental pathogens Klebsiella ssp. was investigated in this study some phenotypic characteristics like antibiotic resistance patterns and biofilm formation properties. A number 483 farms around Konya were examined California Test (CMT) producing 36 posi...

1 Bacterial infections causing mastitis in sheep can result in severe economic losses for farmers. A 2 large survey of milk samples from ewes with mastitis in Sardinia, Italy, indicated an increasing 3 prevalence of Pseudomonas aeruginosa infections. It has been shown previously that during 4 chronic, biofilm-associated infections P. aeruginosa populations diversify. We report the 5 phenotypic ...

Staphylococcus aureus is one of the main etiological agents of mastitis in ruminants. In the present retrospective study, we evaluated the potential interest of a previously described automated multiple loci Variable Number of Tandem Repeats (VNTR) Assay (MLVA) comprising 16 loci as a first line tool to investigate the population structure of S. aureus from mastitis. We determined the genetic d...

Clinical and laboratory studies in an outbreak of Maedi-visna disease in a flock of sheep and goats were conducted. The clinical findings of the disease were loss of wool, dyspnea and coughing, progressive condition loss, exercise intolerance and chronic mastitis. Nervous signs were developed later and were characterized by gait abnormalities of the hind limbs, ataxia, tremor of facial muscles ...

Ovine progressive pneumonia virus (OPPV) infects at least one sheep in 81% of U.S. sheep flocks, as determined by serology, and can cause viral mastitis, arthritis, dyspnea, and cachexia. Diagnostic tests that quantify OPPV proviral load in peripheral blood leukocytes (PBL) provide an additional method for identification of infected sheep and may help to further understanding of the pathogenesi...

In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n=5) or papilloma (Group B, n=3). In the second, teats were chapped and then, the organism was deposite...

Contagious agalactia (CA) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma (M.) agalactiae is the main cause of the disease in sheep and goats. The aim of the present study was to detect M. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or witho...

The isolation, identification of Staphylococcus aureus from bovine milk and its antibiotic susceptibility was studied. One milliliter of each freshly drawn milk sample was inoculated into 9 ml of sterile peptone water and incubated overnight. A loop full of peptone water broth was streaked on blood agar base enriched with sheep blood using the quadrant streaking method for each quarter. Blood a...
