Current research work was carried out for the detection of potential bacterial pathogen and aflatoxigenic fungi Aspergillus spp. from grain comprising [Rice (5), Maize (5), Wheat (5), Khessari dal (5) and Anchora dal (5)] were collected from 3 different local markets of Dinajpur District, Bangladesh. 15 bacterial isolates comprising 4 genera of bacteria were found from a total of 25 samples. The isolated bacteria were Staphylococcus spp., Escherichia coli, Klebsiella spp., Salmonella spp. with 16%, 28%, 16% and 16% prevalence respectively. Antibiogram studies revealed that overall effective drugs against isolated bacteria were Ciprofloxacin followed by Gentamycin. But resistant drugs were Penicillin, Vancomycin, Erythromycin, Kanamycin, and Amoxicillin. The variation in the sensitivity of common antibiotic could be the result of extensive and indiscriminate use of these antibiotics. Aspergillus spp. was isolated from 4-grain samples with 16% prevalence. But aflatoxigenic Aspergillus spp. was isolated from 3 samples with 12% prevalence. From the wheat samples and maize, the aflatoxigenic fungus was isolated and their prevalence in maize, wheat was 40% and 20% respectively. Their early detection can help to take preventive measures to combat economic and health losses. The study showed that earlier detections can be made by simple traditional identifications using macro and micromorphological fungal features rather than adopting the time and cost consuming molecular identification techniques.

Background: The infection of tonsil may occur primarily or secondarily as a result of upper respiratory tract infection, usually preceded by a viral infection. Bacterial tonsillitis is most commonly caused by Streptococcus pyogenes. Penicillin remains the treatment of choice for S. pyogenes tonsillitis. The present study aimed to identify the bacterial pathogen in acute tonsillitis and their sensitivity to antibiotics. Material and Methods: This prospective study was conducted in the Department of Otolaryngology and Head & Neck Surgery and Department of Microbiology, Gandaki Medical College, Pokhara Nepal from January 2018 to January 2019. Ninety-six patients who presented with acute tonsillitis and admitted in the hospital were included in the study. Results: The commonest age group of acute tonsillitis was found to be between 21-30 years. S. pyogenes was the commonest isolate 32(33.3%) followed by S. aureus 19(19.8%).  Streptococcus pyogenes was sensitive to Ampicillin (65.6%) and Cloxacillin (68.7%) while the isolates were more sensitive to levofloxacin and doxycycline. Carbapenem were found to be most effective drugs for intravenous treatment. Conclusion: The most common bacterial isolates were Streptococcus pyogenes. The sensitivity of organism shift from ampicillin group to fluroquinolones and tetracycline. Identification of bacterial isolates and their antibiotics sensitivity patterns could prevent resistance of bacteria to drugs and help in the proper management of acute tonsillitis.

The research work was conducted to isolate and identify the microflora from apparently healthy caged parrots. A total of 45 samples (oral swabs, cloacal swabs and feces) were collected from five types of caged parrots (Gray cockatiels, Rose ringed parakeet, Alexandriane parakeet, Red breast parakeet and Blossom headed parakeet) of Dhaka Zoo during the period from April to August 2009. The samples were cultured on different bacteriological media and the bacteria were identified by their cultural and biochemical properties. All the isolates were allowed for antibiogram study. The bacteria isolated in this study from different types of caged parrots were E. coli (64.44%), Salmonella spp. (46.67%), Staphylococcus spp. (46.67%), Pasteurella spp. (33.33%), Proteus spp. (6.67%) and some unidentified Gram-positive and Gram-negative bacteria. Of these isolates, E. coli was the most frequent isolate. The frequency of Gram-negative bacteria was higher in this study. The percentage of bacterial isolates recovered from each type of parrots was almost similar. Irrespective of types of parrots, the higher percentage of different bacteria was isolated from cloacal swab (77.78%) followed by feces (75.56%). The 68.89% isolates were recovered from oral swab. All the suspected isolates of Salmonella spp. were confirmed by slide agglutination test using Salmonella polyvalent ‘O’ antiserum. Among the 21 Salmonella spp. isolated in this study, 4 (19.05%) isolates were identified as S. Pullorum when tested with specific antisera against S. Pullorum. The results of antibiotic sensitivity tests revealed that ampicillin and amoxicillin were completely resistant to E. coli and Pasteurella spp.; ampicillin to Proteus spp.; and furazolidone to Salmonella spp. and Pasteurella spp. However, the antibiotics of fluoroquinolone group such as ciprofloxacin, norfloxacin and enrofloxacin showed moderate to high sensitivity against almost all the bacterial isolates. Of these, ciprofloxacin was found to be consistently highly sensitive to all the bacterial isolates. DOI = 10.3329/bjvm.v8i1.8349 Bangl. J. Vet. Med. (2010). 8(1): 05-10

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.

Bacterial pathogens are isolated, identified and antibiogram were performed by taking the skin, gills and intestine of twenty randomly selected Tilapia fish (Oreochromis niloticus) that collected from local market of the Dinajpur city, Bangladesh. A serial dilution was prepared with the stated sample and at the amount of 0.1 ml was plated on nutrient agar, differential also specific media respectively. Then gram’s staining, colony morphology, biochemical test and antibiogram performed respectively. The four different isolated species with frequency of occurrence are 31(40.26%) Escherichia coli, 3 (29.87%) Staphylococcus spp., 13 (16.88%) Pseudomonas spp., 10 (12.99%) Salmonella spp. respectively. Some of these pathogens have tendency to transmit to man, who eat fish or deal with fish and fish products. Amoxicillin, Cefixime, Azithromycin, Chloramphenicol, Ciprofloxacin, Penicillin G, Erythromycin, Vancomycin, Gentamicin and Neomycin antibiotics was performed during sensitivity test. Among the total (77) isolated bacteria were sensitive to gentamycin, chloramphenicol, ciprofloxacin and Azithromycin but resistant to Amoxicillin, Penicillin G, Vancomycin and Erythromycin. The study was conducted in term of medical importance. Hence it is considered that a variety of bacterial species can be associated with fresh Tilapia fish related pathogen to humans.

The current study was aimed to detect the presence of contaminating microorganisms in some commonly available spices collected from different areas of Dhaka city, Bangladesh and also to assess their antibacterial activity. Out of eight samples under this study, total viable bacterial count (TVBC) was observed within the range of 106 to 107cfu/g. Among the specific bacterial isolates Staphylococcus spp., Pseudomonas spp. and Escherichia coli were found in almost all the samples within the margin of 102 to 106 cfu/g. Alarmingly Salmonella spp. and Vibrio spp. were presumptively identified in one and two samples respectively. Besides every sample showed the presence of fungus with load up to 103 cfu/g. Antibacterial activity of these samples was tested against seven laboratory isolates. Syzygium aromaticum showed highest activity against as many as five bacterial isolates while Cinnamomum verum was active against four isolates. On the other contrary, both Zingiber officinale and Laurus nobilis demonstrated their antibacterial activity only against Staphylococcus spp. and Klebsiella spp. respectively.

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.

Chicken eggs are a major component of people’s diets, with an average yearly consumption of approximately 103 eggs per person in Bangladesh. Eggs act as an important carrier of food-borne pathogen worldwide. The study was conducted to identify the prevalence and antibiotic resistance pattern of E. coli, Salmonella spp., and Staphylococcus spp., in eggs isolated from farms and different markets of Rajshahi, Bangladesh. A total of 60 eggs were collected randomly between April to December 2019. The isolation and identification of bacterial pathogen was done in accordance with standard procedures. The bacterial isolates were subjected to antibiotic susceptibility testing against seven commonly used antibiotics using Kirby-Bauer disk diffusion method. An overall prevalence of E. coli, Salmonella spp., and Staphylococcus spp. were found to be 35.0%, 28.33%, and 23.33%, respectively. E. coli were found highly resistant to penicillin (100%), tetracycline (80.95%), ampicillin (100%), and erythromycin (85.71%) and were sensitive to amoxicillin (71.42%), ciprofloxacin (85.71%), and gentamicin (95.23%). Salmonella spp. was highly resistant to penicillin (100%), erythromycin (82.35%) and tetracycline (82.35%), and was sensitive to gentamicin (94.11%), amoxicillin (76.47%) and ciprofloxacin (70.58%). Staphylococcus spp. was resistant to penicillin (100%), erythromycin (78.57%), tetracycline (85.71%), amoxicillin (100%), and ampicillin (100%) but sensitive to ciprofloxacin (85.71%), and gentamicin (92.85%). The higher prevalence of multidrug-resistant (MDR) bacteria can easily enter the food chain, which poses a public health threat.
