Emerging drug resistance among Salmonella Typhi and Paratyphi has become challenging in the treatment of enteric fever. The objective of this study was to determine the antibiotic susceptibility pattern of Salmonella serotypes isolated from patients with enteric fever admitted to Manipal Teaching Hospital, Pokhara,Nepal. A total of 30 Salmonella enterica serovar Typhi, Paratyphi A, and Paratyphi B isolated from cases of typhoid and paratyphoid fever admitted to Manipal Teaching Hospital over a period from January 2012 to March 2018 were investigated. All strains were identified by standard microbiological methods and tested for in vitro antibiotic susceptibility testing,using Kirby-Bauer disc diffusion method following the criteria designed by the Clinical and Laboratory Standards Institute (CLSI 2013). S Typhi was the most predominant amongst all the isolates (18 of 30 i.e. 60%), followed by S Paratyphi A (33.3%, 10 out of 30) and S Paratyphi B (6.6%; 2 out of 30). Overall, 91.3% of the isolates were susceptible to chloramphenicol. The percentage sensitivities towards ceftriaxone, ciprofloxacin, cotrimoxazole and ampicillin were 82.6%, 75.8%, 63% and 37% respectively. All the isolates were sensitive to imipenem and amikacin. These findings suggested that there were changing patterns of antibiotic resistance in enteric fever with reemergence of chloramphenicol sensitive Salmonellae. This necessitates continuous surveillance of cases and re-evaluation of chloramphenicol therapy in Salmonella infections in Nepal.

Streptococci are gram positive cocci arranged in chains and are part of normal flora of humans and animals. The present study is carried out to determine the prevalence and risk factors for the carriage of beta-haemolytic streptococci (BHS) among women visiting Dr. VRK Women’s Teaching Hospital & Research Centre, Hyderabad. Vaginal swabs were collected from 250 patients attending outpatient department (OPD) of Dr. VRK Women’s Teaching hospital. Swabs were inoculated onto 5% sheep blood agar plates and incubated for 24 h at 37°C in a candle jar. BHS isolates were phenotypically identified by standard microbiological techniques, all the isolates presumptively identified as BHS were tested for Bacitracin susceptibility. Sensitive isolates were presumptively identified as GAS and resistant isolates were identified as non-group A BHS (NGABHS). Presumptively identified GAS & NGABHS isolates were serogrouped by Lancefield grouping using a commercially available latex agglutination test. BHS were isolated from 12.4% of samples. As many as 12 BHS isolates were identified as GAS and 19 were identified as NGABHS. Ten of nineteen were identified as group B (GBS), 4 (12.9%) were identified as group C (GCS) and 5 (16.12%) were identified as group G (GGS). Among six clinical groups, the prevalence of GAS is highest i.e. 7.5% in female patients visiting Gynaecology OPD with history of white discharge. Prevalence of NGABHS was more among post insertion (18%) IUCD group compared to pre insertion (8%) IUCD group. GBS were isolated from 7% of samples from IUCD group and 4% of samples from prostitutes.This study reports the prevalence of BHS among women visiting a tertiary care hospital in Hyderabad. This study also identified certain risk factors such as IUCD usage and working as a FSW are associated with the increased prevalence of NGABHS especially GBS.

ObjectivesIntramuscular benzathine penicillin G is not available in certain countries. In a previous report, 3 g/day amoxicillin with probenecid was shown to be effective in treating syphilis in patients with HIV; however, 7.3% of patients changed their therapy owing to adverse events. The objective of this study was to assess the clinical efficacy and tolerability of 1.5 g/day amoxicillin without probenecid for the treatment of syphilis.MethodsThe routine clinical records of patients diagnosed with syphilis and treated with 1.5 g/day amoxicillin at a tertiary care hospital between 2006 and 2018 were retrospectively analysed. Syphilis was diagnosed if serum rapid plasma reagin (RPR) titres were ≥8 RU and the Treponema pallidum latex-agglutination test was positive. Serological cure was defined as a ≥fourfold decrease in the RPR titre within 12 months in symptomatic early syphilis and within 24 months in latent syphilis.ResultsOverall, 138 patients (112 with HIV) were analysed. The percentages of primary, secondary, early latent, late latent and latent syphilis of unknown duration were 8.0%, 50.0%, 25.4%, 5.8% and 10.9%, respectively. The median treatment duration was 4.5 weeks (IQR 4–8 weeks), which was not related to the stage of syphilis. Two patients (1.5%) changed treatment due to skin rash. The rate of serological cure was 94.9% (131/138; 95% CI 89.8% to 97.9%) overall; 93.8% (105/112; 95% CI 87.5% to 97.5%) in patients with HIV and 100% (26/26; 95% CI 86.8% to 100%) in patients without HIV. Treatment duration was not related to the treatment efficacy.ConclusionThe regimen of 1.5 g/day amoxicillin without probenecid is highly effective with a low switch rate in patients with and without HIV.

ABSTRACT Aim: The emergence of Methicillin-resistant Staphylococcus aureus (MRSA) has posed a serious therapeutic challenge. We report the prevalence and antibiotic susceptibility pattern of MRSA in the hospitals attached to GMC, Amritsar, Punjab. Materials and Methods: The study comprised of 250 coagulase-positive staphylococci (COPS) isolated from a total of 6743 clinical specimens (like pus, blood, urine, high vaginal swab, sputum, etc.) of patients admitted in hospitals attached to Government Medical College, Amritsar from January 2008−February 2009. Routine antibiotic susceptibility testing was performed and interpreted as per standard guidelines. Methicillin resistance was detected using oxacillin and cefoxitin disc diffusion method, oxacillin screen agar method, and minimum inhibitory concentration using broth macrodilution method. Results: A total of 115 (46%) strains were found to be methicillin resistant. Multidrug resistance was observed in 73% MRSA strains. However, no strain was resistant to vancomycin. Conclusion: Regular surveillance of hospital-associated infection and monitoring of antibiotic sensitivity pattern is required to reduce MRSA prevalence.

Antibiotic Susceptibility Test

Introduction: Extended spectrum β-lactamases (ESBLs) are enzymes that intervene resistance to extended-spectrum (third generation) cephalosporins (e.g., ceftazidime, cefotaxime, and ceftriaxone) and but do not affect carbapenems (e.g., meropenem or imipenem). Though the number of ESBLs producing organism has been increasing day by day, the detection methods and treatment option for them are extremely limited. Objective: Objective of the study was to investigate the rate of ESBLs production and their antibiotic susceptibility pattern. Materials and method: A total 200 Gram negative isolates from various clinical samples received in microbiology laboratory, Sir Takhtsinhji General Hospital, Bhavnagar were studied and Antibiotic susceptibility test was done for commonly used antibiotics. A hospital-based study was conducted in microbiology laboratory, Sir Takhtsinhji General Hospital, Bhavnagar from February 2012 to August 2012. A total of 200 Gram negative isolates from various clinical samples were collected and identified using the conventional biochemical tests following the Clinical and Laboratory Standard Institute (CLSI) guidelines. Antimicrobial susceptibility testing (AST) was performed using the standardized Kirby-Bauer disk diffusion method. Results: Among the total isolates 89(44.5%) were ESBLs producer, and the rate of ESBLs positivity was 39.8% for E. coli (33 out of 83), 10% for Proteus mirabilis (1 out of 10), 51.4% for Klebsiella spp (55 out of 107). ESBLs producing organisms were resistant to most of the antibiotics but 100% were sensitive to imipenem, meropenem, and cefoperazone + sulbactam. Conclusion: Screening for ESBLs production requires to be carried out regularly in all clinical diagnostic laboratories to direct clinicians in appropriate selection of antibiotics.

Among gram-negative microorganisms Pseudomonas aeruginosa is the most common bacteria identified in different clinical specimens of hospitalized patients. A few studies have been conducted in Saudi Arabia regarding antibiotic susceptibility pattern. The purpose of this study was to evaluate the current levels of antibiotic susceptibility and to assess the resistance pattern of antibiotics among the clinical isolates of P. aeruginosa in the King Khalid Hospital, Alkharj, Kingdom of Saudi Arabia. This study was carried out during January, 2015 to May, 2015. A total of 180 different specimens such as sputum, urine, pus swabs, wound swabs etc. were collected from different patients admitted to the hospital. Thirty (30) clinical isolates of P. aeruginosa were isolated from different specimens of the patients suspected of having respiratory tract infection, urinary tract infection, wound infections, etc. The antibiotic susceptibility profiles of all the isolates were determined using Kirby-Bauer disk diffusion method. Piperacillin-tazobactam was found to be the most active antimicrobial agent with 96.7% susceptibility followed by cefepime (83.3%), ceftazidime (83.3%), and ciprofloxacin (76.7%). All isolates were resistant to ertapenem, cefuroxime, cefoxitin and nitrofurantoin. Anti-bacterial treatment strategies should focus on P. aeruginosa, for which the prevalence rates are increasing every year. The usage of piperacillin-tazobactam, cefepime, ceftazidime and ciprofloxacin must be reserved and only be given to the patients after susceptibility test to reduce the resistance of P. aeruginosa against these agents.

Urinary tract infections (UTI) are one of the most common infections in the community and hospitals. Uropathogens colonize the urinary tract and may ascend to bladder causing cystitis, if left untreated reach kidneys through ureters can be responsible for acute pyelonephritis and cause renal damage. The aim of the present study is to determine the prevalence of urinary tract infections and antibiotic susceptibility pattern in a tertiary care hospital.This is an observational study conducted in Microbiology department, Hind Institute of Medical Sciences, Barabanki.A total of 623 urine(mid-stream) samples were collected from indoor and outdoor departments of hospital and culture was done on UTI chromogenic agar using semiquantitative method. Antibiotic sensitivity test was performed using Kirby Bauer disc diffusion method.Prevalence of urinary tract infections is 29% in the study. (43%) is the most common micro-organism isolated followed by (13%), (11%), (10.4%), (8.8%), (3.3%), (1.6%), CONS & (1.1%) and (6.6%). The females(56.6%) are more commonly affected than males.In the present study, beta-lactamase inhibitors and aminoglycosides were effective drugs against gram negative bacteria. Vancomycin and linezolid were sensitive in gram positive bacteria. Nitrofurantoin is the promising drug in cases of uncomplicated UTI, and safe to use in pregnancy. High recurrence rates and antimicrobial resistance are responsible for increasing the burden of disease. It is advised to use the antibiotics judiciously as per the hospital antibiotic policy which will help prevent multidrug resistance micro-organism further reducing morbidity and mortality.

Objectives: The objective of this study was to determine the prevalence of asymptomatic bacteriuria in pregnant women, identify the causative agent responsible for urinary tract infection (UTI) and its antibiotic susceptibility. Methods: The mid-stream urine sample was streaked on the MacConkey agar (MA) and Blood agar (BA) medium by the semi-quantitative culture technique. Identification of significant isolates was done by standard microbiological techniques. Antibiotic susceptibility test of the isolated organisms was done by modified Kirby Bauer disc diffusion method. Results: The prevalence rate of asymptomatic urinary tract infection (AUTI) among pregnant women was found to be 42%. The highest number of UTI cases found during pregnancy was in between age 21-25 years (52.22%), in second gravida (51.59%), during 3rd trimester of pregnancy (49.68%) and in winter with 52.22%. E. coli was principal organism to cause AUTI (35.48%) during pregnancy. Amikacin, imipenem and nalidixic acid were effective towards Gram negative bacilli whereas vancomycin, tetracycline and amoxyclav were effective towards Gram positive cocci. Conclusion: All pregnant women visited for antenatal checkups should be advised for the culture and sensitivity test of their urine specimens which will reduce the maternal and child health complications. Different screening test and awareness programme should be conducted at regular interval of time for prevention of AUTI during pregnancy.

Infections due to multidrug resistant E.coli range from uncomplicated urinary tract infections to life-threatening sepsis. A retrospective study was conducted to determine the patterns of antimicrobial susceptibility in 173 (12.84%) Escherichia coli strains isolated from 1347 clinical specimens of different types. Isolation and identification of E.coli were done as per routine laboratory protocol directed by Cheesbrough1. The isolation rate of E.coli was 48.57% in stool followed by 17.68% in urine, 25% in wound swabs, and 15.38% in tracheal aspirate etc. Among the 173 isolates 102 (59%) were from males and 71 (41%) were from females. Patients were classified into five age groups: 0-15, 16-30, 31-45, 46-60 and >60 years. E.coli was found highest number in females (13.9%) of age range 31-45 years and in males (22%) belonged to age group of over 60 years. Antimicrobial susceptibility testing by the disk diffusion method was conducted for 22 different antibiotics. The majority of isolated E.coli were highly sensitive to Imipenem (98.18%), Meropenem (97.37%), Amikacin (91.67%), Amoxiclav (80%), Ceftazidime (73.33%), and Gentamycin (71.76%). The antibiotics Tobramycin and Azithromycin were found as moderately sensitive against E.coli with the susceptibility rate of 52.5% and 50% respectively. The isolates show low degree of susceptibility to Penicillin G (9.52%), Carbenicillin (10%), Erythromycin (19.48%), Amoxycillin (19.59%), and Ampicillin (25%). These findings have clinical and epidemiological significance and provide a benchmark for future studies on the pattern of susceptibility of clinical isolates of E.coli in this region as well as may help the clinician to prescribe the right empirical treatment.KYAMC Journal Vol. 7, No.-1, Jul 2016, Page 681-686

Aims: To assess the prevalence of A. xylosoxidans isolated from non-respiratory tract samples from adult inpatients and outpatients and the antibiotic resistance levels at a tertiary-care teaching hospital in Szeged, Hungary retrospectively, during a 10-year study period. Study Design: Retrospective microbiological study. Place and Duration of Study: 1st of January 2008 - 31st of December 2017 at the University of Szeged, which is affiliated with the Albert Szent-Györgyi Clinical Center, a primary- and tertiary-care teaching hospital in the Southern Great Plain of Hungary. Methodology: Data collection was performed electronically. Antimicrobial susceptibility testing (AST) was performed using disk diffusion method and when appropriate, E-tests on Mueller–Hinton agar plates. Results: During the 10-year study period, a total of 68 individual A. xylosoxidans isolates were identified (6.8±3.6/year, range: 0-11 isolates). The frequency of isolation in the first half of the study period (2008-2017) was n=22, while in 2013-2017, this number was n=46. The majority of isolates (51 out of 68) were from inpatient departments. 32 out of 68 patients were female (female-to-male ratio: 0.89). The susceptibilities of the respective A. xylosoxidans isolates (n=68) were the following: high levels of susceptibility for imipenem and meropenem (n=63; 92.6%), and moxifloxacin (n=55; 80.9%), while higher rates of resistance were detected for sulfamethoxazole/trimethoprim (susceptible: n=36; 52.9%), ciprofloxacin (susceptible: n=40; 58.8%) and almost all isolates were resistant to ceftazidime (susceptible: n=3; 4.4%) and cefepime (n=2; 2.9%). Conclusion: The existing literature on Achromobacter infections in the context of non-respiratory human infections is scarce, as the incidence of these pathogens in clinically-relevant syndromes in low. The developments in diagnostic technologies in routine clinical microbiology will probably lead to a shift in the isolation frequency of these bacteria in the future.
