Mycoplasma agalactiae is a worldwide serious pathogen of small ruminants that usually spreads through the mammary route causing acute to subacute mastitis progressing to chronic persistent disease that is hard to eradicate. Knowledge of mechanisms of its pathogenesis and persistence in the mammary gland are still insufficient, especially the host-pathogen interplay that enables it to reside in ...

Contagious caprine pleuropneumonia (CCPP) is now a well-defined disease that is caused by Mycoplasma capricolum subsp. capripneumoniae. CCPP is infectious, contagious and fulfils the classic Koch postulates that characterise such types of disease. The distribution of the disease is not exactly known, but reports of mycoplasma isolation and official declarations to the Office International des E...

Brun., 2011, LIX, No. 3, pp. 209–214 The aim of this study was to compare the sensitivity to selected antibiotics in staphylococci isolated from goat (n = 60), sheep (n = 60) and cow’s milk (n = 120). T...

BACKGROUND Clinical mastitis is an important disease in sheep. The objective of this work was to identify causal bacteria and study certain epidemiological and clinical features of clinical mastitis in ewes kept for meat and wool production. METHODS The study included 509 ewes with clinical mastitis from 353 flocks located in 14 of the 19 counties in Norway. Clinical examination and collectio...

This paper reviews the evidence for host genetic variation in resistance to infectious diseases for a wide variety of diseases of economic importance in poultry, cattle, pig, sheep and Atlantic salmon. Further, it develops a method of ranking each disease in terms of its overall impact, and combines this ranking with published evidence for host genetic variation and information on the current s...

Onderstepoort Journal of Veterinary Research, 62:223-226 Over an 8-year period (September 1986 to March 1994), a total of 497 organ specimens from sheep and goats and 96 from cattle, were received for the isolation of Pasteu...

Mastitis is the most complex and costly disease of dairy cows occurring throughout the world. In Ethiopia, the disease is not well investigated. A cross-sectional study to elucidate its magnitude, distribution, and associated risk factors in lactating dairy cows in Southern Ethiopia was carried out from February 2001 to March 2002 in a total of 974 milking cows using California Mastitis Test an...

Udder health troubles in dairy ruminants mainly include intra mammary infections, or mastitis, caused by a pathogen that enter the gland through the teat canal and develop in the gland cistern. Mastitis is a multifactorial disease; it’s origin, severity and outcome are highly variable and depend on environment, a wide variety of pathogens (mostly bacteria) and host. In dairy cattle, mastitis is...

Clinical and subclinical mastitis (SCM), mostly related to intramammary infection (IMI), is prevalent in pastoralist camel herds. An IMI has implications for public animal health as well household economy. As bacterial culturing expensive, time consuming impractical a setting, other early detection methods SCM camels need be investigated. Somatic cell count (SCC) the standard detecting cattle. ...

A morphological, immunohistochemical and polymerase chain reaction (PCR) study was performed on eight ewes experimentally infected with an Italian strain of Maedi-Visna Virus (MVV) in order to evaluate the lesions and the viral distribution after three years of infection. At the moment of euthanasia, seven sheep were seropositive for MVV, while one sheep in poor body conditions was seronegative...
