The research work was conducted for isolation and identification of potential pathogenic bacteria from blow fly (Calliphora spp.) and to investigate their antibiotic susceptibility. For this purpose, 20 blow flies were collected from 4 selected areas (Curzon Hall, Dhaka Medical College Hospital, Fruit Store and Fish Market) of Dhaka city. A total of 40 samples (20 from external surface and 20 from alimentary gut homogenates) were prepared from the blow flies. Among the total 20 flies, 3(15%) were collected from Curzon Hall and 5(12.5%) isolates were obtained from them; 6(30%) flies were collected from DMCH which had 11(27.5%) isolates; 5(25%) flies were collected from fruit stores and 10(25%) isolates were collected from there; 6(30%) flies were collected from fish market and 14(35%) isolates were collected from there. The isolated bacteria were presumptively identified as Escherichia coli, 12 (30%); Salmonella spp., 8 (20%); Shigella spp., 4(10%); Enterobacter spp., 3 (7.5%); Klebsiella spp., 2 (5%); Bacillus spp., 7 (17.5%) and Staphylococcus spp., 4 (10%) in number which were based on morphology as observed under microscope as well as cultural and biochemical properties. All of these isolates were resistant to various antibiotics. Bacterial susceptibility showed that E. coli isolates were highly resistant (66.6%) to Penicillin, Salmonella spp. mostly resistant (62.5%) to Penicillin and Tetracycline. Klebsiella spp. Isolates were 100% resistant to Penicillin and 100% sensitive to Ciprofloxacin, Imipenem and Tetracycline. In case of Shigella spp. and Enterobacter spp., 75% and 100% isolates were resistant to Penicillin respectively. Among the Staphylococcus spp. isolates, 75% were resistant to Ampicillin and Penicillin. In case of Bacillus spp. isolates, 57.2% were resistant to Penicillin and 100% sensitive to Imipenem. Antibiotic resistance of these species affect our human health also. This study demonstrated the potential of blow flies as a vector of various pathogenic microorganisms and a mode of transmission of antibiotic resistance. Bangladesh J. Zool. 49 (2): 205-214, 2021

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.

Antibiotic, known as the magic bullet, was developed to control the growth of pathogenic bacteria. Efficacy of an antibiotic depends on its target site on bacteria. The current public health issue is the emergence of resistant bacterial strains against these drugs. The present study was undertaken to perform the routine antibiotic susceptibility pattern of eight laboratory isolates (Escherichia coli, Bacillus spp., Staphylococcus spp., Vibrio spp., Salmonella spp., Pseudomonas spp., Klebsiella spp. and Listeria spp.) against eleven different categories of antibiotics (Ciprofloxacin, Cephradine, Metronidazole, Cefuroxime, Cefixime, Levofloxacin, Amoxicillin, Azithromycin, Doxycycline, Erythromycin and Flucloxacillin) available in local markets of Dhaka metropolis. Among these antibiotics, Azithromycin, Ciprofloxacin, Cefuroxime, Levofloxacin and Doxycycline showed the highest potency against these bacteria. On the contrary, Amoxicillin and Metronidazole showed almost no potency. Erythromycin, Cephradine and Flucloxacillin gave variable effectivity against the tested isolates. These findings reveal that measures for prevention and containment of antimicrobial resistance are necessary in Bangladesh.

The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba.  Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control.

Pathogenic microorganisms have been so far reported to contaminate a wide range of foods triggering food borne infections or intoxications including the enteric complications, abdominal pain, fever, bloodstream infection etc. The current study was attempted to observe the microbiological quality of some popular foods collected from different places of Dhaka city, Bangladesh. Conventional cultural, microscopic and biochemical tests were followed for the detection and enumeration of bacterial isolates associated with these food samples. The investigation encompassed detection of total viable bacterial count (TVBC) and presumptive identification of other pathogenic bacteria from these samples. Higher counts of TVBC, coliform, Staphylococcus spp. and fungal load were recorded as 1.46×107 CFU/g (yogurt 1), 4.5×106 CFU/g (yogurt 1), 5.6×105 CFU/g (raw meat) and 2.9×103 CFU/g (sea fish), respectively. Fecal coliform was detected only in one out of ten samples. On the contrary Salmonella spp., Vibrio spp., Shigella spp. and Pseudomonas spp. were completely absent. The antibiogram study showed that all the isolates were sensitive against Kanamycin and Azithromycin. Better sensitivity was also observed against Gentamycin and Ciprofloxacin. Varying degree of antibiotic resistance was also detected against Cefixime, Amikacin and Neomycin. Our study emphasizes the need for continuous monitoring of the various categories of food samples for the safety of public health.

Food borne diseases are an increasingly recognized problem involving a wide spectrum of illnesses caused by bacterial contamination of food.Microorganism poses potential human health problems and is mainly transmitted through consumption of contaminated foods .Bangladesh is one of the densely populated country where majority of the people consume cheap foods prepared in unlicensed food selling points. The objective of the present study was to investigate the microbiological quality of different street food (Amra, Fusca, Chanachur and Guava) sold by various street vendor at Dinajpur, Bangladesh. A total of 20 samples were collected randomly from street vendors and tested for the presence of bacteria following standard microbiological method used for isolation, enumaration and identification of bacreria. Among the samples all had bacterial contamination. The total viable count (TVC) in diferrent street food samples was ranged from 8.0 × 105 CFU/g to 6.7x107 CFU/g. Among samples Escherichia coli 7(35%), Staphylococcus spp. 6(30%), Klebsiella spp. 5(25%), Salmonella spp. 1(5%) and Shigella spp. 1 (5%) were isolated. Escherichia coli were found highest 3(50%) Amra samples and 2(40%) Guava samples, then another organisms Staphylococcus spp. was found highest 2(50%) Chanachur and 2(40%) Fusca samples and then Klebsiella spp. was found highest 2(40%) Fusca samples. Antibiotic sensitivity test showed that Shigella spp., Staphylococcus spp., Klebsiella spp., Salmonella spp. and Escherichia coli were sensitive to Ciprofloxacin and Salmonella spp. were resistance to Gentamycin. All isolates found resistant to Cefixime, Cefalexin, Erythromycin, Fusidic acid, Cefuroxime and Aztreonam. All of the sample harbor multidrug resistant food borne bacteria which might cause public health hazards if these antibiotic resistance transfer to human.Asian J. Med. Biol. Res.

Aim: This study seeks to determine the antibiotic susceptibility pattern of bacteria isolated from surfaces of fitness machines at fitness center located at Elizade University and Akure town. Methods: Samples were collected from the different site of gym equipment including thread mill (handle, floor), bicep bench (handle), bike (handle, paddle), cruncher (handle, elbow) using sterile swab stick moistened with sterile buffered physiological solution. The swab sticks were immediately transferred to the laboratory for analysis. Standard microbiological techniques were used to identify the bacterial isolates. The antibiotic susceptibility profile of the isolates was determined by using standard antibiotics discs.  Results: Out of the 31 isolates identified, Staphylococcus aureus 12(38.7%) was the predominant bacteria followed by Bacillus spp. 11(35.5%), Klebsiella spp. 4(12.9%), E. coli and Staphylococcus saprophyticus 2(6.45%) and Enterococcus spp. 1(3.23%). The susceptibility profile showed that all isolates were resistant to Amoxicillin (AM) and Augmentin (AU), Staphylococcus spp. isolated from different surfaces shows different susceptibility pattern to the used antibiotics, while Bacillus spp. Klebsiella spp. and E. coli also confer resistance to more than one commonly used antibiotic. Conclusion: The results showed the occurrence of potential pathogenic bacteria in which their presence on the equipment surfaces could easily be transmitted between users and to the environment generally. The spread of these potential pathogenic microorganisms in the fitness centre can be prevented through frequent hand washing and use of hand sanitizer as well as daily cleaning of equipment surfaces before and after activities with disinfectants.
