ABSTRACT        Background and Objectives: Mastitis caused by Staphylococcus aureus is a widely distributed disease in cattle, goats and sheep. The infection is often subclinical in cattle, leading to reduced milk production and quality, but acute catarrhal or even gangrenous inflammation may also occur. The aim of this study was to investigate resistance of S. au...

Staphylococcus aureus is one of the most frequent mastitis causative agents in small ruminants. The expression of most virulence genes of S. aureus is controlled by an accessory gene regulator (agr) locus. This study aimed to ascertain the prevalence of the different agr groups and to evaluate the occurrence of encoding genes for cytotoxin, adhesins and toxins with superantigen activity in S. a...

Staphylococcus aureus vaccines based on bacterins surrounded by slime, surface polysaccharides coupled to protein carriers and polysaccharides embedded in liposomes administered together with non-biofilm bacterins confer protection against mastitis. However, it remains unknown whether protective antibodies are directed to slime-associated known exopolysaccharides and could be produced in the ab...

Mastitis is by definition, inflammation of the mammary gland. Inflammation is most commonly due to infection with a pathogen (intramammary infection or IMI) but may also be due to injury and less commonly due to allergy and neoplasm. If inflammation is present without a detectable IMI, it may be that the udder was injured, it is recovering from an infection that has self-cured, the infection is...

Neutrophil extracellular traps (NETs) are structures composed of DNA, histones, and antimicrobial proteins that are released extracellularly by neutrophils and other immune cells as a means for trapping and killing invading pathogens. Here, we describe NET formation in milk and in mammary alveoli of mastitic sheep, and provide a dataset of proteins found in association to these structures. Nucl...

To find the association between uterine infection and mastitis to compare effectiveness of ozone treatment antibiotics in curing these infections, 200 dairy cows were screened by culturing milk samples on blood agar containing 5% sheep blood. A total 52 animals either suffering from or infections isolated divided into four groups receive antibiotic treatments i.e., MA (mastitis treated with ant...

ABSTRACT Mastitis is an important infirmity that affects dairy goats and sheep flocks. Antimicrobials are widely used in mastitis therapy; however, the phenomenon of bacterial resistance has sparked interest therapeutic alternatives, especially research on essential oils from several plant species. Therefore, this study aimed to evaluate antimicrobial activity against pathogens importance capri...

A fifteen-year (1991 — 2005) study of reproductive cases in animals presented to the Usmanu Danfodiyo University Veterinary Teaching Hospital, Sokoto, were analyzed based on species, disease condition and sex using clinical case Files of Sheep, goat and cattle. Within the study period a total of 88 reproductive cases were handled out of which 53 (57.95 %) occurred in sheep, 32(36.36 %) goat and...

A total of 272 staphylococcal isolates from cases of bovine mastitis (159 Staphylococcus aureus) belonging to 12 different species were identified with ID32 STAPH galleries, and 51 of them were confirmed by 16S rRNA gene (rrs) sequencing. The same isolates were examined for their hemolytic activity on sheep blood agar, DNase activity, and coagulase activity and with two rapid identification kit...
