“…Staphylococcus epidermidis belongs to the coagulase negative staphylococci (CoNS), a group of Gram-positive cocci that causes a high incidence of bloodstream nosocomial infections [1]. S. epidermidis is a major nosocomial pathogen, frequently isolated from the normal skin microbiota of patients and healthy individuals [2,3].…”

Introduction: Staphylococcus epidermidis is a pathogen associated with nosocomial infection in neonatal intensive care units (NICU). This study investigates an outbreak of methicillin resistant S. epidermidis in an NICU in a hospital in Saudi Arabia. Methodology: A total of 41 isolates identified as Gram-positive cocci were obtained from blood culture, umbilical wound swabs and endotracheal aspirate specimens of neonates, of which 29 were identified as S. epidermidis. Bacterial identification at the species level and determination of antibiotic resistance were performed by MicroScan (Dade Behring, USA). Genotyping was completed using randomly amplified polymorphic DNA (RAPD) and the mecA gene was detected by PCR. Results: All 29 S. epidermidis isolates were found to be resistant to oxacillin and were positive for the mecA gene. The isolates showed several multidrug-resistance patterns; the resistance rates to gentamicin, erythromycin, clindamycin, and trimethoprim/sulfamethoxazole were 89.7%, 86.2%, 75.9% and 72.4%, respectively. All isolates were susceptible to vancomycin, teicoplanin, rifampin, synercid, and ciprofloxacin. Several genotypic and phenotypic patterns were detected among the S. epidermidis isolates: antibiogram typing showed seven different patterns, one of which was shared by 65% of the isolates, whereas the most prevalent RAPD genotype was shared by only five S. epidermidis isolates, and did not correlate with antibiotic resistance phenotype. Conclusion: The diverse clonal origin of tested isolates indicates the presence of multiple S. epidermidis strains among neonates in the NICU setting

“…20 But dental professionals as persistent reservoirs of MRSA in dental institutions are rare, yet important, most frequently acting as vectors and not as the main sources of MRSA transmission. 21 Since MRSA conveyance is of short duration, we may have missed transient carriers of MRSA in the present study which could have been another drawback of the present study. Hence further studies are required with periodic screening of dental health professionals and collecting swabs from other representative sites as well like the throat and hand to get a better picture of the conveyance rates among the dental professionals.…”

Any control program for MRSA requires identifying the whole hospital reservoir. The likelihood of conveyance of MRSA may be higher in dental settings. Hence, the aim was to compare the nasal conveyance MRSA among dental professionals with varying levels of clinical exposure in a tertiary dental hospital in South India. Methods: A total of 81 volunteers were stratified based on the number of years of clinical exposure. The nasal swabs were subjected to catalase and coagulase tests as well as antibiotic susceptibility test. Chi-Square test was done to compare the different types of organisms isolated from dental professionals with varied levels of clinical exposure. Results: Out of the total 81 isolates, 62.96% of the isolates were MSCONS (Methicillin sensitive coagulase negative staphylococcus), 20.98% of them were MRCONS (Methicillin resistant coagulase negative staphylococcus), 9.87% were MSSA (Methicillin sensitive staphylococcus aureus) and 3.7% were MRSA positive and 2.46% were other gram negative organisms. Conclusions: MRCONS, MSSA and MRSA were shown to increase with an increase in the clinical exposure years.

“…1 Although we often think of our hands as instruments of healing, it is important to remember that the hands of healthcare workers are super-colonized with unique numbers and species of potential pathogens. 18 Even innocent and noninvasive touches to the infant or his/her microenvironment present a real risk for transmission. In modern NICUs, where the dangerous combination of micro-preemies and multi-drug resistant pathogens (MDRPs) is propagating in our midst, the issue is exponentially magnified.…”
