The present study was to assess the pattern of antibiotic susceptibility of the isolated bacteria in an urban referral hospital in Dhaka City. A total of 393 bacterial strains were isolated from various specimens over a l0-months period. The majority of the organisms were Escherichia coli Q3.33oh) followed by Klebsiella species (27.480 ), Staphylococcas aureus (l7.Oioh),Lcinetobacter species (8.l4yo), Pseudomonas species (7.l2Yo), and others. The thirdgeneration Cephalosporins Hke Ceftriaxone, Ceftazidime and Cefotaxime were sensitive against 45-66yo isolated Enterobacteriaceae. The first- and second-generation Cephalosporins were less effective. The sensitivity to Ciprofloxacin of various Enterobacteriaceae was only between 33-4Oo compared to 52.8-67.9Vo against Gentamicin. Majority of the Enterobacteriaceae were resistant to Ampicillin, whereas almost all of the Enterobacteriaceae (94-100%o) were sensitive to Imipenem. Ahont97.UY;s Acinetobacter species were susceptible to Imipenem. Sensitivity of the organism (Acinetobacter) to third-generation Cephalosporins ranged between 50-560 , whereas 40.60/o were found sensitive to Ciprofloxacin. The sensitivity to Chloramphenicol, Co-trimoxazole, Cephalexin and Ampicillin ranged between 9.3oh to 34.30 . About 93.0%o of Pseudomonas species were sensitive to Imipenem. The rate of susceptibility to Gentamicin and Netilmicin was higher than those of the Ciprofloxacin and Ceftriaxone (67.80/o and, 53.57o vs, 39.2yo), About 707o of isolated S. aureus were resistant to OxacilHn but all were sensitive to Vancomycin. The result of this study would help the physicians to make a judicious choice of,.anti.biotics for therapeutic purposes.Bangladesh J Med Microbiol 2008; O2 (02):7-ll

Abstract INTRODUCTION: Bloodstream infections (BSIs) can lead to life-threatening sepsis and are globally associated with high morbidity and mortality. Although BSIs require immediate antimicrobial treatment, their prevalence, etiology, and antimicrobial susceptibilities differ from one country to other. There is a dearth of such data from India. Here, we report the 4-year etiologic data on BSI in trauma patients admitted to a tertiary care referral hospital in New Delhi, India. MATERIALS AND METHODS: A retrospective study was conducted at the trauma center between January 2013 and December 2016. The routine microbiological data on bacterial BSI were recorded and determined retrospectively from the laboratory records. Antimicrobial susceptibility profiles were statistically analyzed. RESULTS: A total of 2017 bacterial strains isolated from blood culture samples were included for microbiological analysis. During the study, the median age of the patients varied from 30 to 35 years, with the percentage of females in the study population varying from 17% to 19%. The predominant pathogens were Gram-negative bacteria, with Acinetobacter species, followed by Klebsiella species being the most commonly isolated organisms throughout the 4 years of study. Among Gram-positive isolates, Staphylococcus species were the leading pathogens (11%–15%). CONCLUSIONS: A detailed analysis of prevalence, etiology of BSIs in India and its resistance profile is crucial for appropriate antibiotic use, clinical management, and formulation of antibiotic policies and preventive measures.

ABSTRACT Background:Infection is an important cause of mortality in burns. Rapidly emerging nosocomial pathogens and the problem of multi-drug resistance necessitates periodic review of isolation patterns and antibiogram in the burn ward. Aim:Keeping this in mind, the present retrospective study from wounds of patients admitted to burns unit was undertaken to determine the bacteriological profile and the resistance pattern from the burn ward over a period of three years (June 2002 to May 2005) and was compared with the results obtained during the previous five years (June 1997-May 2002), to ascertain any change in the bacteriological profile and antimicrobial resistance pattern. Materials and Methods:Bacterial isolates from 268 wound swabs taken from burn patients were identified by conventional biochemical methods and antimicrobial susceptibility was performed. Statistical comparison of bacterial isolates and their resistance pattern with previous five years data was done using c2 test.Results and Conclusions:During the period from 2002 to 2005 Pseudomonas species was the commonest pathogen isolated (51.5%) followed by Acinetobacter species (14.28%), Staph. aureus (11.15%), Klebsiella species (9.23%) and Proteus species (2.3%). When compared with the results of the previous five years i.e., 1997 to 2002, Pseudomonas species was still the commonest pathogen in the burns unit. However, the isolation of this organism and other gram-negative organisms had decreased in comparison to previous years. Newer drugs were found to be effective.

Background and Objectives: Acinetobacter baumanii is ubiquitous, aerobic non fermentative, gram negative cocobacilli, emerging globally as an important cause of nosocomial infection. This study was conducted to determine the prevalence and antibiogram of clinically isolated multidrug-resistant Acinetobacter species. Material and methods: Antibiotic susceptibility of 93 Acinetobacter baumannii isolates were performed against ampicillin, ampicillin/sulbactam, piperacillin/tazobactam, ceftazidime, cefepime, ceftriaxone, cefotaxime, ciprofloxacin, levofloxacin, amikacin, gentamicin, imipenem, meropenem, tigecycline, polymyxin B and colistin as per standard methods in microbiology laboratory of Nepal Mediciti Hospital, Kathmandu, Nepal from January to December 2018. Ethical clearance was taken from the Institutional review committee of Nepal Mediciti Hospital. Results: A total of 93 Acinetobacter baumannii isolates were obtained from sputum, blood, pus, wound swabs , catheter tips and others. Antibiotic susceptibility analyses of the isolates revealed that the resistance to ampicillin was most common (100%), followed by cefotaxime (75.2%), ceftazidime (74.1%), ampicillin/sulbactam (73.1%), cefepime (67.7%). However, almost all isolates were susceptible to tigecycline (100%), followed by colistin (98.9%), and polymyxin B (87.0%). Conclusion: The present study showed the increasing trends of resistance of Acinetobacter speciesto various classes of antimicrobials. Treatment options for infections due to MDR and XDR Acinetobacter baumanii are very limited and tigecycline and colistin may be considered as one of the therapeutic option for the treatment of hospital acquired infections

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

Spreads are used widely for making the fast foods more amazing and tasty. Varieties and cross combinations of ingredients are used to make many flavours of fast foods. Different restaurants prepare their signature spreads for attracting people but this can cause opposite result if not prepared using high quality raw materials and proper hygienic conditions are not maintained. Current study was conducted on ten different types of spreads (pesto, cilantro, queso, tomato sauce, peanut butter, honey, mustard, cream cheese, chocolate sauce and butter) which are used by the local restaurants in Dhaka city, Bangladesh. Almost all the samples (nine out of ten) harbored total viable bacteria exceeding the standard limit. Four spread samples showed high fungal count (102 cfu/gm). Four samples showed to be positive (˃101/ml recommended acceptable count) for Escherichia coli and Klebsiella spp. which indicates that these spread cannot be recommended for public consumption. Among all the samples examined, only chocolate sauce showed acceptable result without the presence of coliforms, Staphylococcus spp. and Pseudomonas spp. This finding suggests proper maintenance of sanitation in spread preparation and selling area. A proper guidelines and monitoring can help keep up the quality of food additives. Stamford Journal of Microbiology, Vol.10 (1) 2020: 16-19

Antibacterial Potential

There is an alarming increase in the problem of resistance towards antibiotics amongst most of the pathogenic bacterial strains in recent years. This has drawn the attention of researchers around the world to search for novel and eco-friendly antibacterial compounds. Several biological sources have been explored in this respect but medicinal plants have taken a centre stage out of all. Plants have been known as a reservoir of number of bioactive compounds specially the antibacterial ones since time immemorial. Therefore, the present investigation was undertaken to analyze the antibacterial potential of the medicinal plant Achyranthes aspera. This study revealed that highest antibacterial activity was observed in the methanolic extract of stem against almost all test Bacteria. It showed maximum activity against E.coli (30 mm), followed by S. aureus (28 mm), Enterococcus sp.(25mm), Salmonella typhi ( 20 mm) and least activity was recorded in same extract against K.pneumoniae (6 mm). Four phytochemicals were screened in various solvent extracts. They are alkaloid, flavonoids, saponins and tannins.

The aim of the presented investigation was to describe seasonal changes of microbial community composition in situ in different biocenoses on historical sandstone of the Northern Pergola in the Museum of King John III’s Palace at Wilanow (Poland). The microbial biodiversity was analyzed by the application of Illumina-based next-generation sequencing methods. The metabarcoding analysis allowed for detecting lichenized fungi taxa with the clear domination of two genera: Lecania and Rhinocladiella. It was also observed that, during winter, the richness of fungal communities increased in the biocenoses dominated by lichens and mosses. The metabarcoding analysis showed 34 bacterial genera, with a clear domination of Sphingomonas spp. across almost all biocenoses. Acidophilic bacteria from Acidobacteriaceae and Acetobacteraceae families were also identified, and the results showed that a significant number of bacterial strains isolated during the summer displayed the ability to acidification in contrast to strains isolated in winter, when a large number of isolates displayed alkalizing activity. Other bacteria capable of nitrogen fixation and hydrocarbon utilization (including aromatic hydrocarbons) as well as halophilic microorganisms were also found. The diversity of organisms in the biofilm ensures its stability throughout the year despite the differences recorded between winter and summer.

Bacterial strains become resistant to almost all classes of antibiotics, which makes it necessary to look for new substitutes. The non-absorbable ciprofloxacin–biguanide bismuth complex, used locally, may be a good alternative to a conventional therapy. The purpose of this study was to study the structure of the proposed ciprofloxacin (CIP) -bismuth(III)—chlorhexidine (CHX) composite (CIP-Bi-CHX). The spectroscopic techniques such as UV-VIS (ultraviolet-visible) spectroscopy, FTIR (Fourier-transform infrared) spectroscopy and NMR (Nuclear Magnetic Resonance) spectroscopy were used for structure characterization of the hybrid compound. The performed analysis confirmed the presence of the two active components—CIP and CHX and revealed the possible coordination sites of the ligands with bismuth ion in the metallo-organic structure. Spectroscopic study showed that the complexation between Bi(III) and CIP occurs through the carboxylate and ketone groups of the quinolone ring, while CHX combines with the central ion via the biguanide moieties.
