Introduction: Vaginal discharge syndrome consists of abnormal vaginal discharge, vaginal itching, painful urination and painful sexual intercourse, among them abnormal vaginal discharge is one of the most common clinical symptoms for which most of the female seek care for management in gynaecology and obstetrics outpatient department. Abnormal vaginal discharge in the women of reproductive age can lead to subfertility, ectopic pregnancy, early rupture of membrane, chronic pelvic pain and increases susceptibility for HIV virus and oncogenic virus. Objective: To identify aerobic microflora associated with vaginal discharge and find out most useful drugs for it. Material and Methods: A Hospital based cross sectional study was carried out at Nepalgunj Medical College Teaching Hospital, Kohalpur in November 2016 to November 2017. Ninety- five women who were at reproductive age group with vaginal discharge and met inclusion criteria participated in the study. Samples were taken from posterior fornix of vagina with the help of cotton swab following the confirmation of vaginal discharge by per speculum examination, culture and sensitivity was done. Result: The mean age of participants was 32.7±8.1. Out of 95 participant's samples, aerobic vaginal microfloras were grown in 18 (18.94%) participants and 77 (74.73%) samples was found to be sterile. E. coli and staphylococcus aureus (predominant aerobic vaginal flora) was grown in 7(38.88%). E. coli was sensitive with all available antibiotics in majority of samples showed sensitive to ciprofloxacin, ceftriaxone, tobramycin and meropenam i.e 6 (85.71%) each followed by cefixime and cefpodoxime 5(71.42%), least sensitive with doxycycline 4(57.14%). Similarly, in majority of the samples Staphylococcus aureus was also found to be sensitive with doxycycline, ceftriaxone and meropenam 7(100%) each followed by tobramycin in 6(85.71%), ciprofloxacin and cefixime 2 (28.58%), least sensitive with cefpodoxime 1(14.29%). Meanwhile Ciprofloxacin and tobramycin 2(100%) found to be more effective for klebsiella pneumoniae and doxycycline, meropenam, cefixime and cefpodoxime was found to least effective 1(50%). Chloramphenicol was the only drug sensitive to streptococcus in total collected samples. However Acinetobacter was sensitive with ceftriaxone, ciprofloxacin and doxycycline 1(100%) each but resistant with rest of the antibiotics like meropenam, tobramycin, cefixime and cefpodoxime 1(100%). Most microorganisms were found to be sensitive with ceftriaxone, tobramycin and meropenam 14 (77.77%) and was followed by doxycycline 13 (72.22%) and ciprofloxacin in 11 (61.11%). Cefpodoxime 11(61.11%) and cefixime10 (55.55%), they found poorly in sensitivity test. Conclusion: Bacterial culture and its sensitivity in vaginal discharge should be done not only because of its troublesome symptoms but for its complications like subfertility, preterm delivery, ectopic pregnancy and it's increased susceptibility for HIV and oncogenic virus. E. coli and staphylococcus were the predominant bacteria found in present study and were followed by klebsiella pneumoniae, streptococcus and acinetobacter. In this study, Ceftriaxone (85.7%) and meropenam (100%) were found to be more effective for E.coli and staphylococcus aureus respectively, ciprofloxacin could be used as a choice of drugs for E.coli (sensitivity 85.7%). However for staphylococcus, doxycycline was a better option with 100 % sensitivity.

The successful conduct of disinfection measures largely depends on the availability of veterinary practice a highly efficient, environmentally safe disinfectants. In this regard, finding new highly efficient disinfectant remains relevant. Studies found that the "Polied" (OOO "Razvitie XXI Vek, Russia) can be attributed to the highly efficient and environmentally friendly means. Solutions "Polied" have a high disinfectant activity against smooth and rough surfaces in the laboratory against gram-positive, gram-negative bacteria, mycobacteria and spores of microorganisms. Studies have established that solutions should be "Polied" obezzarajivatmi E. coli (EA 1257) concentrations of 0.1% on smooth surfaces and Staphylococcus aureus concentration of 0.05% in 1 hour from the calculation of 0.25-0.3 litres/m2. Disinfection of rough test surfaces against Escherichia coli and Staphylococcus aureus occurred after treatment with 0,3% solution of 3-hour exposure, at a rate of 0.5 l/m2. It was also found that 1.0% solution "Polied" fully obezzarazhivatel test the surface of mycobacteria (PCs-5) and at double the 0.6% concentration for 24 hours. Disinfection of rough test surfaces contaminated with spores of B. cereus (PCs 96) was achieved with a 4.0% solution at twice the irrigation rate of 0.5 l/m2 at an exposure of 24 hours. Toxicity solutions of the drug "Polied" refer to "moderate" threat (hazard class 3) and low-hazard substances (4 hazard class) when applied to the skin, mucous membranes of the eyes, and inhalation exposure on the respiratory system.

Introduction: In this project, the growth and volatile metabolites profiles of Escherichia coli (E. coli ) and Staphylococcus aureus were monitored under the influence of silver base chemical, nanoparticle and ultra-highly diluted compounds. Materials & Methods: The treatments were done for 12000 life cycles using silver nanoparticles (AgNPs) as well as ultra-highly diluted Argentum nitricum (Arg-n). Volatile organic metabolites analysis was performed using gas chromatography mass spectrometry (GC-MS). The results indicated that AgNPs treatment made the bacteria resistant and adapted to growth in the nanoparticle condition. The use of ultra-highly diluted Arg-n initially increased growth but it decreased later. Also, with the continuous usage of these materials, no more bacterial growth was observed. Results: The most important compounds produced by E. coli are Acetophenone, Octyl acetate, Styrene, 1,8-cineole, 4-t-butyl-2-(1-methyl-2-nitroethyl)cyclohexane, hexadecane and 2-Undecanol. The main compounds derived from S. aureus are Acetophenone,1,8-cineole, Benzaldehyde, 2-Hexan-1-ol, Tridecanol, Dimethyl Octenal and tetradecane. Acetophenone and 1,8-cineole were common and produced by both organisms. Conclusion: Based on the origin of the produced volatiles, main volatiles percentage of untreated sample is hydrocarbon (>50%), while bacteria treatments convert the ratio in to aldehydes, ketones and alcohols in the case of AgNPs, (>80%) and aldehydes, ketones and terpenes in the case of Arg-n (>70%).

Contamination of meats and meat products with foodborne pathogenic bacteria raises serious safety issues in the food industry. The antibacterial activities of phosphorous-fluorine co-doped TiO2 nanoparticles (PF-TiO2) were investigated against seven foodborne pathogenic bacteria: Campylobacter jejuni, Salmonella Typhimurium, Enterohaemorrhagic E. coli, Yersinia enterocolitica, Shewanella putrefaciens, Listeria monocytogenes and Staphylococcus aureus. PF-TiO2 NPs were synthesized hydrothermally at 250 °C for 1, 3, 6 or 12 h, and then tested at three different concentrations (500 μg/mL, 100 μg/mL, 20 μg/mL) for the inactivation of foodborne bacteria under UVA irradiation, daylight exposure or dark conditions. The antibacterial efficacies were compared after 30 min of exposure to light. Distinct differences in the antibacterial activities of the PF-TiO2 NPs, and the susceptibilities of tested foodborne pathogenic bacterium species were found. PF-TiO2/3 h and PF-TiO2/6 h showed the highest antibacterial activity by decreasing the living bacterial cell number from ~106 by ~5 log (L. monocytogenes), ~4 log (EHEC), ~3 log (Y. enterolcolitca, S. putrefaciens) and ~2.5 log (S. aureus), along with complete eradication of C. jejuni and S. Typhimurium. Efficacy of PF-TiO2/1 h and PF-TiO2/12 h NPs was lower, typically causing a ~2–4 log decrease in colony forming units depending on the tested bacterium while the effect of PF-TiO2/0 h was comparable to P25 TiO2, a commercial TiO2 with high photocatalytic activity. Our results show that PF-co-doping of TiO2 NPs enhanced the antibacterial action against foodborne pathogenic bacteria and are potential candidates for use in the food industry as active surface components, potentially contributing to the production of meats that are safe for consumption.

The aim of the study is to synthesise and. Characterize — some novel, "tetrazole., -5-thiol” derivatives. Firstly, the “1-phenyl-1H7-tetrazole-5-thiol” (A1) has been., synthesised by the reaction of phenylisothiocyanate with NaN3 in water as a solvent. Secondly, the tetrazole-5-thiol derivatives (A2-A4) were synthesised by the alkylation reaction of the compound (A1) with chloroacetone, phenacyl bromide and chloromethyl acetate respectively. The resulted percentage yield was relatively high (92%, %95, %90 respectively). Compound (A5) was synthesised by the reaction of ethyl acetate tetrazole derivative (A4) with hydrazine. Moreover, the derivatives (A6-A11) were synthesised by the reaction of the (A5) with various substituted aromatic aldehydes. Moreover, compounds (A12-A13) have been synthesised by the cyclization reaction of compound A5 with acetylacetone and phenyl acetylacetone respectively. The produced compounds have been identified by IR, 13C-NMR and 1H-NMR Spectroscopy, and the quantities of various of the physical data (melting point, the shape of crystal and color). Finally, the compounds were examined for their biological activities alongside two kinds of bacteria (E. Coli and Staphylococcus aureus). Compounds A2, A4, A8, A11 and A13 showed the highest inhibition activity against E. Coli. Compounds A2, A9, A10and A13 showed the maximum activity against Staphylococcus aureus.

Ham sandwiches inoculated with a mixture of five enteropathogenic bacteria, Bacillus cereus, Clostridium perfringens. Escherichia coli, Salmonella typhimurium and Staphylococcus aureus, were held at 30, 21 and 4 C for up to 24 h. Food poisoning potential was judged by the growth and survival of the inoculated pathogens. Major differences were observed between new and old (30 days of storage at 4 C) ham samples. On new ham, all enteropathogens were able to grow except C. perfringens, whereas on old ham, with high microbial competition. the pathogens survived but did not grow. Severe storage temperature abuse was necessary to develop a food poisoning potential in new ham samples. The safety of old ham was attributed to the competitive microflora that grew in the ham during storage at 4 C for 30 days. Infective pathogens, E. coli and S. typhimurium, either survived or increased in numbers under all test conditions. The safety of vacuum packaged sliced ham for use in sandwiches, in its present market form, was indicated by these studies.

Ham and chopped ham from two manufacturers were contaminated with five enteropathogens: Bacillus cereus, Clostridium perfringens, Escherichia coli, Salmonella typhimurium and Staphylococcus aureus, at time of slicing and vacuum-packaging, to simulate contamination by manufacturer. Subsequent treatment of the samples, representing sound and undesirable retail handling and consumer use conditions, indicated marked differences in the fate of the pathogens between these products and within product type between the two manufacturers. Greatest differences were observed between the chopped ham products. All pathogens, except C. perfringens, grew actively in fresh ham and chopped ham with abusive holding at 30 and 21 C. After storage at 4 or 10 C for 30 days, B. cereus and C. perfringens were no longer detected, even after subsequent holding at 30 or 21 C for 24 h. E. coli survival and growth was variable, S. typhimurium survived well and grew under some conditions and S. aureus was generally inhibited at high levels of competition.

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
