The main objective is to determine the sensitivity, specificity, positive predictive value and negative predictive value of MCRA and TAM against TCP method. A total of 50 Staphylococcus aureus strains resistance to methicillin and Ciprofloxacin from all clinical isolates from April 2015 to March 2016 was subjected to biofilm detection methods. Out of 50 S. aureus resistant to methicillin and ciprofloxacin, 26(52%) were found to be biofilm producers.

The present study was carried in the Department of Microbiology, MMIMSR, Haryana on 200 clinically suggested cases of corneal ulcers. Corneal scrapings were subjected to microscopy and culture. Of 200 suspected cases, 43.5% were culture positive. Staphylococcus aureus and Pseudomonas aeruginosa were the predominant gram positive and negative bacterial isolates. Aspergillus species was the most prevalent fungal isolate.

Staphylococcus aureus recently shows resistance to many Beta lactam antibiotics and Carbapenems. This study is focused on the incidence of MRSA in NICUs. Using Gram staining, blood culture and antibiotic sensitivity tests, MRSA can be identified. Septicemia is diagnosed not only by the isolation of the organism in blood culture. It should be correlated with total count, CRP like lab investigations and clinical features. Sometimes repeated blood culture is needed to confirm the diagnosis and to assess the prognosis.

Methicilin–resistant Staphylococcus aureus (MRSA) is a common cause of serious nosocomial infections with limited options for treatment due to its known resistance to many antibiotics. Knowledge guided antibiotic combination therapy can be of great benefit in fighting this superbug. The aim of this study was to evaluate the combined activity of penicillin G (A) and gentamicin (B) against clinical isolates of methicillin resistant Staphylococcus aureus.

Staphylococcus aureus is one of the most common organisms causing nosocomial and community acquired infections worldwide. Antibiotic resistance in this organism has become an ever-increasing problem. Present study was undertaken to determine the percentage of Staphylococcus aureus isolates having inducible clindamycin resistance. A total of 270 Staphylococcus aureus isolated from different specimens were subjected to routine antibiotic sensitivity testing by Kirby Bauer disc diffusion method.

The increasing methicillin resistant Staphylococcus aureus (MRSA) infections pose a serious threat. Accurate and rapid detection of methicillin resistance is important for ensuring the prompt start of antibiotherapy and control of MRSA in the hospitals. Molecular detection of mecA gene is the gold standard for identification of MRSA isolates. However, many laboratories don’t have the capacity for molecular techniques. Resazurin is a dye used as an oxidation reduction indicator in bacterial cell viability assays.

The present study was conducted to evaluate antimicrobial and cytotoxicactivity of Sisymbrium irio L extract against MDRB (Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, Acinetobacter baumanni, Enterobacter cloacae and Pseudomonas aeruginosa) and Candida albicans. Antibiotic sensitivity profile was performed using disc diffusion method. Cytotoxicity was measured against African Green Monkey Kidney (VERO) cell line using the colorimetric MTT assay.

In recent times, the treatment of Staphylococcus aureus infection has become problematic because of emergence of resistance to antibiotics which is a cause of concern for all the clinicians and microbiologists worldwide. Infections caused by MRSA have been associated with high morbidity and mortality rates. Hence this study was conducted to know the prevalence of Methicillin resistant Staphylococcus aureus [MRSA] isolates in various clinical specimens and to determine the sensitivity of these isolates to different antimicrobial agents.

The present study was carried out to isolate Methicillin-Resistant Staphylococcus aureus (MRSA) in clinical samples. Standard microbiological and biochemical methods were used to screen 404 clinical specimens comprising of pus, urine and blood.58 isolates were MRSA out of 194 Staphylococcus aureus isolates. MRSA is increasing. Most MRSA are resistant to several non-beta lactam antibiotics. Frequent monitoring of susceptibility patterns of MRSA and formulation of a definite antibiotic policy may be helpful in decreasing incidence of MRSA infection.

Many plants in Africa are medicinal. The use of medicinal natural plants predates the establishment of antibiotics and other modern drugs into the African continent. The antibacterial activity of Gongronema latifolium and a synthetic antibiotic (Rocephin) on a clinical isolate of Staphylococcus aureus was evaluated in vivo using albino Wister rats. Five (5) adult female rats with weight ranging from 120 – 180 kg were purchased, housed, fed and nurtured for five days. Four (4) of the rats were inoculated with 0.1 ml 4hour growing broth culture of Staphylococcus aureus.

Nosocomial infection is a key factor in determining clinical outcomes among patients admitted in intensive care units. Studies on nosocomial infections in ICUs found that respiratory tract infections, blood stream infections, urinary tract infections and soft tissue infections are the common nosocomial infections in ICUs. These organisms causing nosocomial infections are highly resistant to antibiotics. Early recognition of bacteria and appropriate antimicrobial therapy are essential for controlling infection, preventing the morbidity and improve the quality of life.

Staphylococcal mastitis is a major and costly problem of dairy cattle all over the world. In the present study, Clinical (n=165) and sub-clinical mastitic milk samples were processed for bacterial isolation. All the 83 isolates recovered on primary isolation were confirmed as Staphylococcus spp. based on morphological and biochemical characteristics. Based on the result of tube coagulase test, 55 (66.27 %) isolates were considered as a Staphylococcus aureus, whereas 28 (33.73 %) isolates were considered as Coagulase-negative staphylococci (CoNS).

Staphylococcus aureus causes skin and soft tissue infections (SSTIs), if not treated with proper antimicrobials can leads to serious form of infection. Multi-drug resistant strains left us very few therapeutic alternatives, in such cases clindamycin can be a good option with true sensitivity. The clinical samples exhibiting skin and soft tissue infection received in the department of microbiology further subjected to isolation of Staphylococcus aureus. Isolated strains further subjected to D-test to detect inducible clindamycin resistant strains as per standard guidelines.
