Diagnostic Centre

Different types of diseases inflict the inhabitants of Dhaka city from time to time. The focus of this study was to investigate disease prevalence, etiology and antibiotic sensitivity profiles reported at a local diagnostic service in Dhaka, Bangladesh. Pathogens were transported from a renowned local diagnostic centre in Dhaka city in Trypticase Soy broth (TSB) to the laboratory. Antibiogram was performed by Kirby Bauer disc diffusion assay. A total of 110 samples (20% blood (n = 22), 60.9% urine (n = 67), 13.64% pus (n =15), 3.64% sputum (n = 4) and 1.82% wound swab samples (n = 2) were collected for further investigation. Of the patients, 30% were male and 70% were female. In case of blood samples from diarrheal patients, Salmonella enterica serovar Typhi (72.7%) and S. enterica serovars Paratyphi (27.2%) were predominant. Both serovars were sensitive to Cefixime, Ceftriaxone and Gentamicin and resistant to Nalidixic acid. E. coli (91%) was the predominant pathogen in Urinary Tract Infection (UTI) patients followed by Klebsiella spp. (8.9%). E. coli exhibited resistance to Cephalosporins and Ciprofloxacin whereas Klebsiella spp. were, however, sensitive to these antibiotics. Both species showed resistance against Amoxicillin and sensitivity to Imipenem, Merpenem and Colistin. In pus samples, S. aureus (46.7%) prevailed followed by Klebsiella spp. (26.7%) and E. coli (26.7%) spp. All S. aureus isolates were sensitive to Fusidic acid, Vancomycin, Linezolid and Piperacillin and 50% were sensitive to Cephalosporins and Ciprofloxacin and resistant to Amoxycillin and Azithromycin. E. coli and Klebsiella spp. from pus samples could be inhibited by Carbapenem. As with UTI isolates, E. coli from pus were resistant to Cephalosporins, Ciprofloxacin and Amoxicillin whereas 66% Klebsiella spp. were sensitive to the first two. A total of 66% of E. coli and Klebsiella spp. showed sensitivity to Gentamicin and Amikacin. It was observed that there was a similarity in the antibiotic sensitivity pattern of the same bacterial spp. isolated from different disease cases. As a general rule, it was observed that Imipenem is a good treatment option for treating E. coli and Klebsiella spp., Cephalosporins for Salmonella while a number of treatment options existed for S. aureus infections.

Background: Acute lymphoblastic leukemia (ALL) is the commonest malignancies in childhood. Common obstacle in the treatment of ALL is febrile neutropenia and its complications. Objectives: To identify bacteria causing infection, their isolation rate and antibacterial sensitivity pattern in hospitalized febrile neutropenic children with ALL in different cycle of chemotherapy. Methodology: This observational study conducted in 2014 - 2015 in the department of paediatric haematology and oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Bangladesh. Sixty febrile neutropenic episodes from 52 diagnosed cases of ALL aged 0 to18 years were included. Complete blood count, blood culture, urine microscopy and culture, serum alanine aminotransferase, serum creatinine were done in every patient. X-ray chest, stool microscopy and culture, pus, wound, throat and aural swab for culture & sensitivity were done in selective patient. Results: Bacterial infection was confirmed by culture in 15 (25%) episodes from 60 febrile neutropenic episodes. Fifteen (25%) organisms were isolated from the study subjects from sample of blood (60%), pus (13.3%), aural swab (13.3%), wound swab (6.7%) and throat swab (6.7%) respectively. All isolates were gram negative. The organism isolated were Klebsiella spp. 5 (33.31%), E. coli 4 (26.7%), Acinetobacter 3 (20%), Pseudomonas 2 (13.3%) and only one (6.7%) Enterobacter species. All the isolates of the Klebsiella spp., E. coli and Acinetobacter spp. were resistant to amoxicillin. All isolated E. coli were resistant to cotrimoxazole, ceftazidime, ceftriaxone, cefotaxime and ciprofloxacin, Acinetobacter spp. Isolated were 100% sensitive to imipenem, colistin sulphate & piperacillin-tazobactam and resistant to cotrimoxazole and cephradine. All Pseudomonas spp. showed 100% sensitivity to imipenem, amikacin, ciprofloxacin & colistin and resistances to ceftazidime. Conclusion: The species of Klebsiella were the predominant causative bacterial agent followed by Escherichia coli, Acinetobacter spp, pseudomonas spp. and Enterobacter spp. They showed resistance to commonly prescribed antibiotics ceftazidime, gentamicin, ceftriaxone & ciprofloxacin and sensitive to imipenem, colistin-sulphate & piperacillin-tazobactam.

Background: Non fermenting gram negative bacilli (NFGNB) are usually considered to be non pathogenic commensals of little significance, however, data suggest that they are remarkable because of antimicrobial resistance; propensity to cause outbreaks and complex epidemiology. This study was conducted to find out the prevalence and sensitivity pattern of NFGNB from various clinical samples.Methods: A total of 519 samples were received from patients suspected of having hospital acquired infections (HAI), admitted in Sawai Man Singh Hospital, Jaipur, India. Organisms grown on culture were subjected to phenotypic identification along with antimicrobial sensitivity testing by Kirby Bauer’s disc diffusion method.Results: Among 366 culture positive samples, 94 (25.6%) NFGNB were isolated. Maximum pevalence prevalence was found in burn ward i.e. 76.7 % followed by surgical wards 71.0%, surgical ICUs 69.6% and medical ICUs 68.0 %. Highest yield was found in pus/wound samples (95.5%) while it was only 23.7% in blood samples. Pseudomonas aeruginosa was the most common isolate (48.9%), followed by Acinetobacter baumannii (33%), Stenotrophomonas maltophilia (13.8%) and Burkholderia cepacia complex (4.3%). P.aeruginosa and A. baumanii strains were most sensitive to Meropenem. S.maltophilia showed maximum sensitivity with ticarcillin/ clavulanic acid and B. cepacia complex with Piperacillin/ Tazobactam.Conclusion: Isolation of NFGNB and their antibiotic susceptibility pattern should be regarded with all seriousness in clinical practice and epidemiology because they are emerging nosocomial pathogens and by being resistant to multiple antibiotics, their prevalence not only limits the treatment options but also act as a reservoir of drug resistance genes.Nepal Journal of Medical Sciences Vol.3(2) 2014: 101-105

Milk is such a food which can meet almost all nutritional needs of human lives. Raw or unprocessed milk supports the growth of wide variety of microorganisms. The major interests of this study were examining the microbial quality of raw milk collected from different locations of Jessore city in Bangladesh and determining antibiotic susceptibility pattern of some isolated bacteria. To do so, 12 raw milk samples were collected from different areas of Jessore city. Microbial analysis comprised of enumeration of TVC (total viable count), TCC (total coliform count) and TSC (total staphylococcal count). The highest TVC, TCC and TSC were 1.95x109 CFU/ml, 2.5x107 CFU/ml and 1.02x107 CFU/ml respectively. Prevalent bacterial populations were Klebsiella spp., Enterobacter spp., Shigella spp. Staphylococcus spp., Escherichia coli and Citrobacter spp. In order to observe the antibiotic susceptibility pattern, the antibiotic sensitivity test was performed for some randomly selected isolates of E. coli and Klebsiella spp. More than 90% isolates of Klebsiella spp. were found to be resistant against Erythromycin whereas more than 90% isolates were sensitive against Imipenem. On the other hand, 100% E. coli isolates were observed as resistant against Erythromycin and in case of Trimethopreme 100% isolates were sensitive. Multidrug resistance pattern was also found. These results suggest the necessity of hygienic practices during handling, processing and post-processing of raw milk to improve the microbiological quality and safety of raw milk.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23723Bangl.

Mortality in broilers (6.56%) and growing ducks (11.0%) caused by Escherichia coli was recorded in the experimental flocks study during the period from May to August 2003. E. coli organisms isolated from broiler birds affected with characteristic lesions of omphalitis and yolk sac infection, fibrinous pericarditis and peri-hepatitis , hemorrhagic enteritis, and accumulation of excessive pericardial and peritoneal fluid, whereas from ducks with lesions of hemorrhagic enteritis and extensive epicardial hemorrhages. Each of the 21 isolates collected from broilers and 11 isolates from ducks was characterized by cultural and biochemical studies, of which 8 isolates from broilers and 5 isolates from ducks were tested for antibiotic sensitivity with 9 different antibiotics. The antibiotic sensitivity pattern showed that the isolates were highly sensitive to ciprofloxacin but an increasing trend of resistance was recorded in broilers (7 / 9) than duck (4 / 9) isolates. It may be concluded from the results of this study that the high rate of E. coli infection in broilers and ducks along with the high resistance of isolates to antibiotics constitute a threat to the poultry industry in Bangladesh.

Background: Diabetes mellitus (DM) is an immunosuppressive condition and uncontrolled diabetes is associated with increased susceptibility to various infections like pneumonia. Community acquired pneumonia (CAP) in diabetic patients is often caused by more virulent or atypical organisms and associated with increased resistance to conventional antibiotics. The aims of this study were to identify the bacterial etiology of CAP in patients with DM and to see their antibiotic sensitivity pattern.Methods: This was a cross-sectional, observational study conducted in the Department of Internal Medicine & Pulmonology of BIRDEM General Hospital, Dhaka, Bangladesh, from January 2013 to December 2015. A total of 120 hospitalized diabetic patients diagnosed with CAP and with a positive sputum culture growth of any bacteria were included in the study.Results: Majority (67%) of the patients were male. Mean age of the patients was - 55.69 ±10.5 years. Mean duration of diabetes was - 7.35 ±1.3 years. Mean HbA1c was - 8.6 ±1.89%. Sputum for culture showed that out of 120 (100%) patients, Klebsiella pneumoniae was detected in 53 (44.2%) patients, Staphylococcus aureus in 18 (15.0%), Pseudomonas species in 16 (13.3%) patients, Acinetobacter in 10 (8.3%), Escherichia coli in 9 (7.5%) patients and 14 (11.7%) patients had growth of other organisms. Sensitivity pattern of different bacterial growth in sputum to commonly used antibiotics like ceftriaxone, ciprofloxacin, amikacin and imipenem were as follows – Klebsiella (19%, 47%, 74%, 96% respectively), Staph aureus (11%, 33%, 78%, 67% respectively), Pseudomonas (19%, 75%, 81%, 88% respectively), Acinetobacter (0%, 0%, 20%, 50% respectively), E. coli (22%, 22%, 100%, 100% respectively). All (100%) of the Pseudomonas and Acinetobacter were sensitive to colistin. Most of the growth of all the bacteria (Klebsiella 94%, Staphylococcus 78%, Pseudomonas 81%, Acinetobacter 100%, E. coli 100%) occurred in patients with poor glycemic control (HbA1c ? 7.0%).Conclusion: This study results suggest that CAP in diabetic patients are more frequently due to Klebsiella pneumoniae, Staphylococcus aureus and Pseudomonas species and mostly they are less sensitive to commonly used antibiotics like ceftriaxone and ciprofloxacin. So, whenever possible, treatment of CAP should be guided by sputum culture and sensitivity test and for empirical treatment of CAP in diabetic patients, alternative antibiotics like imipenem and amikacin should be considered.Birdem Med J 2017; 7(2): 101-105

Infection that occurs in Indonesia has increased more significantly than before, compared to the increasing bacterial multidrug resistance (MDR) as the cause of infection. A study conducted in 5 hospitals in Indonesia in 2013 showed that the prevalence rate of extended-spectrum β-lactamase (ESBL)-producing bacteria reached 32-68%. The objective of this study is to detect the prevalence and resistence pattern of ESBL-producing Escherichia coli and Klebsiella pneumoniae in Dr. Zainoel Abidin General Hospital, Banda Aceh. This study was conducted from 1 September 2016 to 31 December 2016. Specimen types included in this study were blood, sputum, urine, pus, mucosal swab, and another body fluids sample. The sampling method in this study was total sampling that is all clinical specimen examined in Clinical Microbiology Laboratory. Isolation and identification ESBL-producing bacteria was performed by VITEK-2 machine (Biomerieux). The result of this study is that a total 122 E. coli and K. pneumoniae were isolated. That consisted of 48 (39%) E. coli isolates and 74 (61%) K. pneumoniae isolates. From 48 E. coli isolates it was found out that 41 (85%) had ESBL phenotypes and from 74 K. pneumoniae isolates it was found out that 59 (80%) had ESBL phenotypes. In total, 100 (82%) isolates from 122 isolates had ESBL phenotypes. Distribution of ESBL-producing E. coli and K. pneumoniae based on sample was 24 (89%) isolates from the total of 27 urine isolates, 18 (95%) isolates from the total of 19 blood isolates, 28 (78%) isolates from the total of 36 sputum isolates, and 30 (75%) isolates from the total of 40 pus isolates. Antibiotic sensitivity pattern of the E. coli and K. pneumoniae isolates had high sensitivity to amycasin dan meropenem which was above 89%. Meanwhile, it also had sensitivity to Fosfomycin and Piperacyclin-Tazobactam by 80% and 77% respectively. Another antibiotic was less effective

Fruits are highly nutritious, sources of vitamins, minerals, fibers etc. and these are part of our daily diet. However, during cultivation, harvesting, transportation, handling fruits get contaminated with pathogenic microorganisms which leads to severe problems to community. Owning to this point, in current research, bacteriological analysis was performed on Sofeda, Pineapple, Grape, Banana, Apple, Orange, Guava, papaya, Jujube and Starfruit. Total 50 samples were randomly collected from market and street vendors of Dhaka city. Higher numbers of rotten fruits were present in wholesale markets. 35 strains were isolated which included Salmonella spp., Acinetobacter spp., Klebsiella spp., Vibrio cholerae, Vibrio parahaemolyticus, Staphylocoous aureus and E. coli. They were identified using biochemical test and antibiogram for selective isolates. In case of drug resistance of isolates, majority exhibited resistance against Erythromycin, Vancomycin and Amoxycillin and showing sensitivity against Ciprofloxacin and Ceftriaxone. It was observed in the current study that 100% isolates were resistant against Erythromycin, followed by Amoxycillin 90.63% and vancomycin 86.25%, where only 35.27% isolates were resistant against Ciprofloxacin. In case of sensitivity 64.73% isolates were sensitive against Ciprofloxacin followed by Ceftriaxone 66.25%.

Due to delicious taste and readily availability, desserts are one of the most popular foods in Dhaka city. High amount of carbohydrate and protein in dessert items make them more susceptible to proliferation of microbial growth. Present study depicted a complete microbiological profile of some popular desserts such as, sweet, pastry, ice cream, pudding, falooda, yogurt and custard available in different food shop at Dhaka city, Bangladesh. All the samples were found to be contaminated with heterotrophic bacteria as well as fungi within the range of 103 to 106 cfu/g. In case of specific microflora, the growth of Staphylococcus spp., Klebsiella spp. and Pseudomonas spp. were observed in most of the samples indicates the poor quality of these products. Bioburdens of E. coli in sweet, pudding and yogurt were found in the range of 1.2×102 to 2.7×103 cfu/g. Salmonella spp., Shigella spp. and Vibrio spp. could not be isolated from any of the samples. Current study indicates that hygienic conditions should be maintained during preparation, packaging and retailing of dessert items in order to reduce the load of contamination in ready to eat foods which will ensure good health of consumers.

Background: Urinary tract infection (UTI) being one of the most common and a serious health problem both in the community and hospital settings each year worldwide, the emergence of antibiotic resistance in the management of UTI is a serious public health issue. The present study will analyse the antimicrobial sensitivity pattern of pathogens isolated from the urine samples of admitted patients suffering from UTI in Tripura Medical College and Dr. B.R. Ambedkar Memorial Teaching Hospital (TMC).Methods: This was a hospital record-based study. The urine samples of clinically diagnosed UTI patients admitted in various departments of the hospital during the study period were included. The reports of culture and sensitivity testing of the samples were collected. The results were interpreted according to the guidelines of the Clinical and Laboratory Standards Institute (CLSI).Results: During the 12-month study period, a total of 752 urine samples were analysed. Enterococcus (43.75%) was the most frequently isolated bacteria, followed by E. coli (28.45%) and Klebsiella (14.89%). Enterococcus was highly sensitive (p<0.001) to vancomycin (95.33%), E. coli was mostly sensitive to nitrofurantoin (83.65%) and Klebsiella mainly sensitive to imipenem (75.49%).Conclusions: The study showed that positive urine culture with the antibiotic sensitivity of the isolates is very important for antimicrobial therapy, as antibiotic resistance is a worldwide problem which causes ineffectiveness of treatment.
