Background: Antimicrobial sensitivity pattern from clinical isolates can reveal important information that can help in drafting the hospital antibiotic policy as well as help improve prescribing patterns and patient outcome in a particular region.Methods: Data from the results of the antimicrobial sensitivity pattern of clinical isolates of the patients between 1stJuly and 31st December 2018 were collected on a pre-designed and pre tested case study form and analysed with the help of descriptive statistics.Results: A total of 75 blood culture reports were obtained which showed 58 gram positive cultures. Further 46 of the gram positive samples were positive for Coagulase negative Staphylococcus. A total of 305 urine samples were obtained for culture which showed gram negative cultures. Paediatric and medicine wards were the common yielding sites. A total of 242 pus reports were obtained which showed 47 gram positive cultures. A total of 154 wound swab samples were obtained which showed 47 gram positive cultures. For pus and wound swab samples, surgery wards were the common yielding sites. Common gram negative organisms seen were Klebsiella sp., E. coli, Citrobacter sp., Pseudomonas, Proteus and Enterobacter. Gram positive organisms were commonly resistant to Erythromycin, orally active Penicillins, Vancomycin and Teicoplanin and gram negative organisms were commonly resistant to Cephalosporins, Aminoglycosides, Colistin, Fluroquinolones and Meropenem.Conclusions: This study showed that over six months samples of body pus, wound swab, blood culture and urine showed high levels of resistance to commonly used antibiotics. This would provide an outline for development of an effective hospital Infection Control Policy.

Background: Tuberculosis is appraised to cause the deaths of more than a billion people in the last decades. Objectives: The current study compares the performance of microplate Alamar blue assay for clinical isolates of Mycobacterium tuberculosis and multidrug-resistant tuberculosis. Microplate Alamar blue assay was performed in a central tuberculosis laboratory at Golestan University of Medical Sciences in Gorgan, Iran. Methods: In the first step, the microplate Alamar blue assay was used for the detection of 78 clinical isolates in the Golestan Regional Tuberculosis Reference Laboratory, and the results were compared with those of the proportion assay. In the second step, the microplate Alamar blue assay and the proportion assay were used for the drug susceptibility of 35 isolates. Results: In the microplate Alamar blue assay, the sensitivity was 100 (90.97 - 100), with a specificity of 74.36 (57.87 - 86.96), positive predictive value of 79.59 (65.66 - 89.76), and negative predictive value of 100 (88.06 - 100). For the microplate Alamar blue assay with rifampin, the sensitivity was 100 (89.11 - 100), specificity was 100 (29.24 - 100), positive predictive value was 100 (89.11 - 100), and negative predictive value was 100 (29.24 - 100). For the microplate Alamar blue assay with isoniazid, the sensitivity was 84.38 (67.21 - 94.72), specificity was 66.67 (9.43 - 99.16), positive predictive value was 96.43 (81.65 - 99.91), and negative predictive value was 28.57 (3.67 - 70.96). Conclusions: We found high accuracy between the microplate Alamar blue assay with rifampin and the proportion assay. The rapid and low-cost microplate Alamar blue assay is an inexpensive and appropriate assay for the detection of rifampin-resistant tuberculosis in low-income countries.

A study of antimicrobial sensitivity of Pseudomonas aeruginosa isolated from clinical sources from different diagnostic centers, Dhaka, Bangladesh was carried out to facilitate the preference of drug in the management of Pseudomonas aeruginosa induced symptoms. Very low sensitivity of P. aeruginosa towards co-trimoxazole (45%), azithromycin (30%) and erythromycin (35%) was observed. Higher sensitivity pattern was observed for cefuroxime (57.5%). and only imipenem (100%) has shown sensitivity pattern possibly susceptible enough to consider for the management of P. aeruginosa induced cases in the area under study. The low sensitivity to different antimicrobial could be attributed to their prevailing usage and abuse in the area under study.Keywords: Antimicrobial sensitivity; Clinical isolates; Pseudomonas aeruginosa.© 2011 JSR Publications.

Antimicrobial Sensitivity

General objectives: This study aimed at assessment of factors affecting antimicrobial sensitivity in Staphylococcus aureus clinical isolates from Assir region, Saudi Arabia. Materials and Methods: In this study, eighty one patients presented with Staph. aureus infections either nosocomial or community acquired infections were involved by collecting nasal swabs from them at Aseer Central Hospital General Lab. These patients were from all age groups and from males and females during the period of Jan 2011- Jun 2011. These samples were undergone variable laboratory procedures mainly; bactech, culture media, antibiotics sensitivity test using diffusion disc test (MIC) and molecular (PCR) for detection of mec A gene. Clinical and laboratory data were recorded in special formats and analyzed by statistical computer program (SPSS). Results: Showed that; Descriptive and analytical statistical analysis were performed and final results were plotted in tables. In Staph aureus MecA gene positive cases (50) showed: Oxacillin/ Mithicillin, Ciprofloxacin and Fusidin resistant in diabetic patients were 13, 26.0%, 9, 18% and 7, 14% respectively and in non diabetic patients were 37, 74.0%, 22, 44% and 20, 40% respectively. While no sensitivity in diabetic and non diabetic patients using Oxacillin/ Mithicillin. In Staph aureus MecA gene negative cases (31) showed: Oxacillin/ Mithicillin, sensitivity in diabetic patients (5, 16.1%) and in non diabetic were (26, 83.9%). While no resistant in diabetic and non diabetic patients. In Ciprofloxacin and Fusidin resistant in diabetic patients were 1, 3.2% and 1, 3.2% respectively and in non diabetic patients were 12, 38.7% and 7, 22.6%respectively. Erythromycin in Staph aureus ( MecA gene) positive cases (50) showed: resistant in age (0-15) years were (5, 10%), (16-50) years were (16, 32%) and ( ›50 years) were (12, 24%). Erythromycin in Staph aureus (MecA gene) negative cases (31) showed: resistant in age (0-15) years were (6, 19.3%), (16-50) years were (5, 16.1%) and ( ›50 years) were (3, 9.7%). Conclusion: Drugs resistance is a major progressive multifactorial problem facing the treatment of Staph aureus infections.
