The antibiotic resistance pattern was observed significantly in various geographical locations. Routine surveillance is therefore essential for constant monitoring of AMR rates in the clinically important pathogens. It is imperative to track the changing resistance pattern over time, to guide proper therapeutic strategies to combat infections due to drug-resistant pathogens. This study aims to highlights the distribution of aerobic bacterial isolated from pus samples, and their susceptibility to different antibiotics collected during 2017 (July to December) in a tertiary care hospital. Nearly 637 clinical pus samples were received during July to December 2017 to the Department of Microbiology, Tertiary care hospital, Puducherry. Bacterial identification was performed using standard conventional biochemical tests and antibiotic susceptibility was carried out according to CLSI guidelines 2017 on each one of the aerobic bacterial isolates from the pus samples. Among the isolates 76.5% were Gram-negative bacilli (GNB) as well as 23.5% were Gram-positive cocci (GPC). The most common bacteria isolated were Pseudomonas spp 24.88% (108 in 434), followed by Escherichia coli 21.66% (94 in 434), Staphylococcus aureus 19.82% (86 in 434) and Klebsiella pneumoniae 13.13% (57 in 434). Of the 86 (19.82%) Staphylococcus aureus isolates, 16 (18.40%) were MRSA. Pseudomonas aeruginosa was highly susceptible to the carbapenems and least susceptible to ciprofloxacin. Acinetobacter baumannii was the most resistant organism according to this study and showed the least susceptibility to ceftriaxone and maximum susceptibility to aminoglycosides. This study concluded that the Pseudomonas aeruginosa isolate was found to be a predominant in our clinical pus samples. Gram negative bacteria are more commonly associated with the pyogenic lesion that Gram positive. A high level of an antibiotic resistance was observed in most of our bacterial isolates.

Objective: To determine the spectrum and antibiotic resistance pattern of uropathogens causing urinary tract infection among inpatients and outpatients in a tertiary care hospital in Karachi Methods: This descriptive cross-sectional study was conducted in the Department of Microbiology, Sindh Institute of Urology and Transplant, Karachi, The study was conducted from March 2016 to March 2017 after taking approval from the Hospital Ethics Committee. Urine specimens were analyzed to establish a diagnosis of UTI and identify uropahtogens. The antibiotic susceptibility pattern of uropathogens was studied using disc diffusion method against the following antibiotics; fosfomycin, ampicillin, amoxicillin-clavulanate, nitrofurantoin, cefotaxime, ceftazidime, amikacin, cefoxitin, imipenem and vancomycin. Results: A total of 480 samples of UTI were received during the study period. The average age of patients was 54.79±12.09 years. The majority of samples came out positive from the male gender (65%) and in-patient department (n=400, 83.3%). The highest prevalent microorganism was E.coli (82.1%) followed by Klebsiella spp (14%), Pseudomonas aeruginosa (1%), Proteus mirabilis (1%), Morganella morgannii (1%) and Staphylococcus aureus (0.8%). All microorganisms were highly resistant to augmentin, cefoxitin, cefotaxime, ceftazidime. Only pseudomonas aeruginosa was highly resistant to imipenem (60%). Pseudomonas aeruginosa (100%), E.coli (86.8%) and Klebsiella spp (71.6%) were highly sensitive for Amikacin (100%). Morganella morgannii (80%) and Proteus Mirabilis (40%) were mainly resistant to Fosfomycin. Only E.coli was sensitive to nitrofurantoin (74.1%). Conclusion: The presented study demonstrated that gram-negative bacteria was the most frequent cause of urinary tract infection. Microorganisms showed variable resistance to different antibiotics. The first line of antibiotics should be rationally selected by physicians to treat urinary tract infections.

Antibiotic Resistance Pattern

Background: Osteomyelitis is a common cause of morbidity in developing countries. Its treatment comprises of surgical debridement of all necrotic bone and soft tissue along with use of appropriate antimicrobial therapy. Treatment is becoming increasingly troublesome due to rise in drug resistant isolates in osteomyelitis cases. The present study was done to determine the antibiotic resistance pattern among aerobic bacterial isolates from osteomyelitis cases.Methods: 125 samples from osteomyelitis cases were aerobically cultured and isolates from culture positives were identified by standard procedures. Antimicrobial susceptibility testing was done by Kirby Bauer disk diffusion method. Staphylococcal isolates were screened for methicillin resistance and Gram negative bacilli were screened and confirmed for ESBL, AmpC and MBL production.Results: Out of 125 samples cultured, 20 were culture negative and 105 were culture positive giving rise to 120 isolates (58 Gram positive and 62 Gram negative organisms). The prevalence of methicillin resistant staphylococcal (MRS) isolates, ESBL, AmpC and MBL producers was found to be 43.1%, 51.6%, 24.2% and 14.5% respectively. All the resistant isolates were multidrug resistant, with MRS being 100% sensitive only to vancomycin, linezolid and teicoplanin, ESBL and AmpC producers being 100% sensitive only to imipenem and colistin, and MBL producers being 100% sensitive only to colistin.Conclusions: Antibiotic therapy on the basis of antibiotic susceptibility pattern helps the clinician to choose appropriate drugs leading to successful treatment and prevention of emergence and dissemination of drug resistant isolates.
