Abstract Objective To determine prevalence and relevance of coagulase-positive Staphylococcus hyicus and S intermedius intramammary infections (IMI) in dairy cows and determine the ability of the 4-hour tube coagulase (TC) test to differentiate the coagulase-positive staphylococci (CPS). Design Prevalence of CPS was determined for primiparous cows (point prevalence and prevalence at first parturition) and multiparous cows (point prevalence) of 2 herd groups: < 6% CPS IMI prevalence = low prevalence (LP); > 10% CPS IMI prevalence = high prevalence (HP).

SUMMARY A comparison was made between conventional tube coagulase, macrocupsular coagulase, latex agglutination, and miniaturized biochemical test systems for identification of Staphylococcus aureus of bovine origin. A total of 303 gram-positive, catalase-positive cocci of bovine origin were tested. Agreement between each pair of 4-hour tube coagulase, macrocupsular coagulase, latex agglutination, and miniaturized biochemical test results within isolates was > 95.0. Seventeen (5.6%) isolates were test negative for 4-hour tube coagulase, but test positive for 24-hour tube coagulase. Thirteen

Abstract:

Introduction: The accurate identification of Staphylococcus aureus clinical isolates requires a series of tests. Morphological features and slide coagulase test are two criteria on which S. aureus are identified. Resort to tube coagulase test is sought when results of slide coagulase test are equivocal or doubtful. Both coagulase tests detect the enzymes that convert fibrinogen into fibrin. Human, rabbit or sheep pooled plasma is used as substrate for both tests. Slide coagulase test is simpler and faster as compared to tube coagulase test.

The test for coagulase activity is a simple and non-expensive test for the identification of S. aureus strains from clinical samples in resource-poor settings. The results of these tests have been reported to vary with the source of plasma and with some atypical strains that test negative with the coagulase test. The study was carried out to determine if misidentification of strains of S. aureus exists on account of the reliance on the coagulase tests.

In order to shorten the test protocol, different preincubation times of S. aureus in BHI were evaluated.

ABSTRACT Mastitis is an inflammation of the mammary gland that affects dairy cattle worldwide causing economic losses.

So, the aim of this study was to characterize the Staphylococcus spp. strains initially classified as coagulase-negative Staphylococci, isolated from buffalo with subclinical mastitis.

Abon used is non-branded beef abon which is as many as 10 samples obtained by total sampling technique. Samples were tested by observation of colony morphology through Gram staining, mannitol fermentation test, catalase and c

Abstract:

Coagulase positive staphylococci are one of the most common causes of chronic udder infection. Indiscriminate use of antimicrobial drugs and their presence in the environment where animals live has led to coagulase positive staphylococci strains resistant to antimicrobial means. Proper and timely treatment of sub-clinical mastitis, based on the most effective use of antimicrobial drugs, is the key to good health of the milk herd. The aim was to determine the antimicrobial efficacy of selected assets in relation to coagulase positive staphylococci isolated from samples of milk taken from indivi

Highlights: 1. The significance of Staphylococcus aureus and coagulase-negative Staphylococcus, which are more likely to infectimmunocompromised patients, needed to be researched in greater depth.2. Coagulase-negative Staphylococcus was found to form significantly more biofilm than Staphylococcus aureus.3. Wound care and changing medical devices in immunocompromised patients on a regular basis may provide benefitsto prevent biofilm formation by Staphylococcus spp. Abstract Staphylococcus spp. are typically commensal microorganisms that can exist in the human body without causing illness.

This study aimed to determine the phenotypic and genotypic identification and differentiation of typical coagulase positive Staphylococcus aureus (CPSA) and atypical coagulase negative Staphylococcus aureus (CNSA) from other Staphylococci isolated form bovine milk. Out of 111 milk samples, 67 Staphylococcus strains were isolated, phenotypically, based on resistance to Acriflavine; Staphylococcus aureus (S. aureus) was detected in 44 isolates of them (30 CPSA strains and 14 CNSA strains). Twenty five from CPSA and 5 from CNSA isolates were positive for slime production on Congo red agar plates.

When compared with the conventional tube method using rabbit plasma, none of the 6 commercial methods was suitable for identification of S intermedius, although the 6 tests performed well using strains of S aureus. Use of rabbit plasma identified more S intermedius isolates than did use of dog plasma.
