Study was planned to determine the prevalence of sub clinical mastitis in crossbred and indigenous cows and to characterize etiological agent/s involved along with their antimicrobial sensitivity testing. Milk samples from 364 quarters of 95 lactating cows at an organized farm were screened. The overall quarter wise and animal wise prevalence on the basis of cultural examination was 64.21 and 3...

Mastitis is considered to be the most economically costly disease affecting the dairy industry. Regular dosage of animals with antibiotics, including use of prophylactic concentrations, may select for resistant strains. The purpose of this study was to determine the mode of action of a new bacteriocin (macedocin ST91KM), to evaluate the antimicrobial resistance of mastitis pathogens to antibiot...

Streptokinase is an extracellular protein secreted by various strains of streptococci and is used clinically as an intravenous thrombolytic agent for the treatment of acute myocardial infarction. It is well established that the fibrinolytic activity of streptokinase originates in its ability to activate plasminogen. The present investigation was carried out to determine the extent of streptokin...

To shed light on the role of Streptococcus equisimilis (SE) in the pathogenesis of intervertebral disc infection, we report here a case of lumbar spondylodiscitis in a 37-year-old male caused by SE, with identification of this strain by cultures from L4-L5 lumbar disc biopsy. Intravenous therapy with penicillin and gentamycin combined with immobilization resulted in a rapid and complete recover...

Background Necrotizing fasciitis (NF) retains a very high mortality rate despite prompt and adequate antibiotic treatment and surgical debridement. Necrotizing fasciitis has recently been associated with Streptococcus dysgalactiae subspecies equisimilis (SDSE). Methods We investigated the causes of a very severe clinical manifestation of SDSE-NF by assessing both host and pathogen factors. ...

mastitis, inflammatory disease of mammary glands, can be caused by various microorganisms. many antimicrobial agents have been evaluated to combat the causative agents. development of resistance in pathogens against conventional antibiotics may be high; hence at present study in vitro efficacy of a new fluoroquinolone antibiotic (marbofloxacin) against isolated pathogens from clinical mastitis ...

BACKGROUND & OBJECTIVES Group C and group G streptococci (together GCGS) are often regarded as commensal bacteria and their role in streptococcal disease burden is under-recognized. While reports of recovery of GCGS from normally sterile body sites are increasing, their resistance to macrolides, fluoroquinolone further warrants all invasive β haemolytic streptococci to be identified to the spec...
