Nowadays in Staphylococcus aureus isolates resistant to lincosamide, macrolide and streptogramin B (MLSB) group of antibiotics are expanded. Therefore, clindamycin is preferred drug for the treatment of infections caused by S. aureus, but due to change in sensitivity patterns of clindamycin it is leading to treatment failure. The three resistance phenotypes of MLSB antibiotics are iMLSB (inducible resistance) and cMLSB (constitutive resistance) that are resistant to macrolides, lincosamides and streptogrammins B antibiotics, whereas MS resistance that is sole resistant to macrolides and streptogramins B antibiotics. Erythromycin ribosome methylase (erm) genes are responsible for expressing inducible clindamycin resistance among S. aureus. In the present investigation, a Double disc approximation/Disc induction test (D-test) and PCR were used. Out of 428 strains the prevalence of iMLSB, cMLSB and MS phenotypes were 36 (8.41%), 47 (10.98%) and 48(11.21%) respectively. It is concluded that D-test should be routinely done to avoid treatment failure due to clindamycin resistance. In addition, PCR is a simple, quick, reliable and sensitive method that could also be used in the detection of inducible clindamycin resistance. The reason for the lower prevalence of iMLSB phenotype in the present study could be due to the reason that samples included in this study were mostly from the rural areas as the exposure of antimicrobial agents is less.

Antimicrobial Susceptibility Pattern

Methicillin resistant Staphylococcus aureus (MRSA) is major cause of nosocomial and community infections. Its prevalence varies with country and with hospitals within a country. Therefore, it is important for continuous surveillance in hospitals and other healthcare facilities in order to limit the spread of infections caused by MRSA. To determine the antibiogram of Staphylococcus aureus in a tertiary care hospital and to determine the change in trends in the antimicrobial susceptibility pattern of Staphylococcus aureus. To determine the prevalence of MRSA in a tertiary care hospital. This cross- sectional study was conducted at the Department of Microbiology, SMSR, Sharda University and Hospital. A total of 100 strains identified by morphological and biochemical characteristics were tested for antibiotic susceptibility using Kirby-Bauer disc diffusion method and the Prevalence of Inducible Clindamycin Resistance among the isolates. 100 out of 13,639 isolates clinical comprising samples were obtained Pus (78.6%), Blood (7%), Swab (4.1%), Sputum (4.1%), Urine (4.1%), Semen (2%). Maximum MRSA were obtained from pus samples (81%). However, out of total 7 isolates of Staphylococcus aureus obtained from blood 4 were MRSA and 3 were MSSA. The prevalence of MRSA that is (40%) infections was a high in our setup and is comparable to studies done earlier. This trend is particularly alarming for Staphylococcus aureus because of the severity and diversity of disease caused by this uniquely versatile pathogen.
