Relatively few phages (<10) of coagulase negative staphylococci (CoNS) have been described. Staphylococcus epidermidis phage vB_SepS_SEP9 is a siphovirus with a unique morphology as a staphylococcal phage, possessing a very long tail. Its genome is unique and unrelated to any phage genomes deposited in public databases. It appears to encode a nonfunctional integrase. Due to the not having a rec...
Methicillin-resistant coagulase-negative staphylococci were isolated from the nares and skin of 1- to 8-week-old healthy chickens in three flocks from a farm. Isolation of methicillin-resistant coagulase-negative staphylococci was positive for 72 (25.7%) of the 280 chickens tested, with the frequency varying from 2.2 to 100% according to flock. A total of 45 appropriate isolates were selected a...
The objective of this study was to evaluate the prevalence of coagulase-negative staphylococci in healthy dogs and to determine whether methicillin-resistant staphylococci expressed the mecA gene. Nasal and rectal swab samples were taken from 50 clinically healthy dogs. The prevalence of coagulase-negative staphylococci was evaluated according to phenotypic properties. The agar diffusion method...
This specimen was presented as a blood culture (bacteremia) isolate and was to be identified and tested for antimicrobial susceptibility. The culture contained a Staphylococcus epidermidis, a common isolate from blood cultures, some being considered skin contaminates. High rates of methicillin resistance are observed in coagulase-negative staphylococci (CoNS) such as S. epidermidis, thus requir...
Aerobic In clusters ● Coagulase (+): Staphylococcus. aureus ● Coagulase (-):Staphylococcus lugdunensis or other coagulase-negative Staphylococcus In pairs/chains ● Optochin sensitive: Streptococcus pneumoniae ● Alpha-hemolytic: Viridans group Streptococcus, Enterococcus species ● Beta-hemolytic: ○ Group A Strep (Streptococcus pyogenes) ○ Group B Strep (Streptococcus agalactiae) ○ Group C, D, G ...
INTRODUCTION Coagulase-negative staphylococci (CoNS) are a group of micro-organisms that are increasingly implicated as a cause of significant infection and the leading cause of bloodstream infection (BSI). One important predictor of true BSI is the isolation of CoNS from multiple blood cultures, presuming that the isolates represent the same species. Thus the objective of this study was to det...
Coagulase-negative staphylococci (CoNS) have been associated with a range of human health issues such as medical device-related infection, localized skin or direct are recognized comprising the main part normal microbiota and severe intensive infections, causing infections in humans, especially immunocompromised patients neonates. S. haemolyticus is, after Staphylococcus epidermidis, second mos...
Coagulase-negative Staphylococcus spp. (CoNS) represent a major cause of bloodstream infections, especially in patients with prosthetic devices and intravenous catheters. We evaluated the activity of daptomycin in comparison to vancomycin and teicoplanin against a large collection of 22,024 CoNS isolates causing clinically significant infections from 283 medical centers over 9 years (2002-2010)...
PURPOSE To evaluate the fluoroquinolone susceptibilities of ocular isolate coagulase-negative staphylococci (CoNS), identified at the Microbiology Laboratory - UNIFESP. DESIGN Experimental laboratory investigation. METHODS The minimum inhibitory concentrations (MICs) of 21 strains of methicillin-resistant coagulase-negative staphylococci (MRCoNS) and 22 methicillin-sensitive coagulase-negat...
OBJECTIVES The aim of this study was to determine the occurrence of fusidic acid resistance, mediated by the fusB gene, among coagulase-negative staphylococci (CoNS) isolated from bovine mastitis. METHODS A total of 113 CoNS isolates were screened for susceptibility to fusidic acid by using a disc diffusion method. The fusB gene was detected by using PCR and subsequent DNA sequencing. The loc...
