Aims: The aim of this study was to characterize bacteria isolated from circulating Kenyan banknotes and also antibiotic susceptibility profiles within Nyeri County. Study Design:  This was a cross-sectional study and simple random sampling was used to collect 25 of each paper currency denomination. Place and Duration of Study: Samples analyses were done at Outspan Teaching and Referral Hospital (OTRH) laboratory, between March, 2019 and April, 2019. Methodology: Total of 125 currencies of five different denominations were collected from different marketing sources such as Butcheries, Restaurants, Health facilities, Mpesa outlets and Transport Saccos and dropped in sterile bags. The bacterial isolates were characterized on the basis of their morphology, staining and biochemical tests. Antibiotic sensitivity tests were done by Kirby Bauer disc diffusion technique. Results: Total of 19 different bacterial species were isolated from five Kenyan Bank note currencies. Of these, 37 (52.2%) was Staphylococcus aureus followed by Staphylococcus sciuri ssp.lentus 7 (9.9%), Staphylococcus gallinarum 2 (2.8%), Staphylococcus intermedius 6 (8.5%), Micrococcus sp. 1 (1.4%), Staphylococcus schleiferi ssp.coagulans 2 (2.8%), Staphylococcus sciuri ssp.rodentium 1 (1.4%), Kluyvera ascorbata 1 (1.4%), Proteus penneri 1 (1.4%), Aeromonas media 3 (4.2%), Burkholderia cepacia ssp.komplex (1.4%), Aeromonas enteropelogenes 1 (1.4%), Enterobacter cloacae 1 (1.4%), Klebsiella oxytoca 2 (2.8%), Leclercia adecarboxylata 1 (1.4%), Raoultella ornithinolytica 1 (1.4%), Vibrio metschnikovii  1 (1.4%), Myroides odoratus 1 (1.4%) and Yersinia pestis 1 (1.4%). Overall gram positive and gram negative bacterial isolates exhibited resistance to vancomycin, clindamycin and amoxycilin with percentages 40 (71%), 28 (50%), and 37 (66%) and 9 (64%), 8 (57%) and 6 (43%)  respectively. Conclusion: This study revealed that Kenyan banknote currencies circulating in Nyeri County were contaminated with different pathogenic and potential pathogenic bacteria including multi drug resistant strains. Hence, great care must be taken while handling money during the preparation and handling of food to avoid cross contamination.

Introduction: Patients with malignancies frequently develop infections as a result of surgical procedures and fungating wounds leading to pus formation. This cross-sectional study was conducted to explore the bacteriological spectra of infections of various cancer sites and their antibiotic sensitivity patterns among the patients visiting minor operation theatre (OT) of B.P. Koirala Memorial Cancer Hospital (BPKMCH), Chitwan, Nepal. Methods: Over a period of 3 months from September to November 2018, a total of 183 wound exudates and pus samples were collected and analyzed by standard microbiological procedures. Isolates were identified based on the colony characters, Gram staining and an array of biochemical tests. Antibiotic susceptibility testing was performed by Kirby-Bauer disc diffusion technique according to criteria set by CLSI, 2016. Methicillin resistance in Staphylococcus aureus was tested with the help of cefoxitin using disc diffusion method. Results: Out of the 183 samples, 149 (81.4%) were culture positive. Among 13 different isolates identified, S. aureus (43.0%) was predominant followed by E. coli (14.0%). Higher incidence of bacteria was seen among the males (52.3%), in the age group 51 to 60 years (26.8%) and among the patients undergoing surgical intervention to deal with cancer (34.2%). The prevalence of wound infection was significantly affected by gender, age, and treatment regimen ( P < .01). Out of the total 68 S. aureus isolates, 38 (44.1%) were deemed as Methicillin-resistant Staphylococcus aureus (MRSA). Among the 158 isolates, 85 (53.8%) were multi-drug resistant (MDR). Cefepime was the most effective antibiotic for Gram positive isolates whereas both imipenem and meropenem were found to be equally more effective for Gram negative isolates. Conclusion: This study suggests that patients with malignancies harbor pathogenic bacteria; therefore, prudent use of antibiotics is essential to prevent the emergence of MDR pathogens.

Motorcycle Helmets

Background. Motorcycle helmets can serve as a potential vehicle for the transmission of pathogenic bacteria and fungi with serious health implications. The main aim of this study was to explore the microbial diversity associated with the motorcycle helmets and determine the antibiotic susceptibility profile of the bacterial isolates. Methods. A descriptive cross-sectional study was carried out among the teaching staffs of Birendra Multiple Campus, Bharatpur, Nepal. A total of 130 motorcycle helmets worn by the teaching staffs of the Birendra Multiple Campus, Bharatpur, were included in the study for microbiological investigations. Results. Of the total 130 motorcycle helmets analyzed, 392 bacteria and 346 fungi belonging to seven different genera were recovered. Staphylococcus aureus 89 (22.7%) was the predominant bacteria followed by S. epidermidis 77 (19.6%) and E. coli 54 (13.8%), whereas Aspergillus niger 67 (19.4%) was the predominant fungi followed by A. fumigatus 49 (14.2%). Antibiotic susceptibility test was performed by the disc diffusion method for all the bacterial isolates. Tetracycline, gentamycin, and cotrimoxazole were the most effective antibiotics for Gram-positive isolates, whereas Gram-negative isolates were sensitive towards imipenem and ciprofloxacin. Of the total bacterial isolates, 153 (39.0%) were multidrug-resistant (MDR), 10.4% were extended-spectrum beta-lactamase (ESBL) producers, and 4.3% were metallo-beta-lactamase (MBL) producers and, out of 89 isolates of Staphylococcus aureus, 30 (33.7%) were detected as methicillin-resistant Staphylococcus aureus (MRSA). Conclusion. The findings suggest that motorcycle riders should follow good hygiene practices and regularly clean their helmets with suitable sterilants to avoid the risk of microbial contamination and reduce the associated risks.

Introduction: Infections due to antibiotic resistant bacteria have increased alarmingly in both developed and developing countries. Unrestrained and rapidly spreading bacterial growth has turned the management of wound infections into a serious challenge. This study aimed to determine the prevalence of different bacterial pathogens and their antibiotic susceptibility in various types of wound infections. Methods:  A cross-sectional study was conducted to collect 105 wound swabs. All isolated bacteria were identified based on colony characteristics, gram stain and standard biochemical tests, and antibiotic susceptibility testing (AST) with the disc diffusion method. Descriptive statistics were used to present the study findings, and all analyses were performed using Stata Version 13. Results:  The rate of isolation of bacteria was 92.3%. Staphylococcus aureus was found to be the most frequent isolate (55.7%), followed by Escherichia coli (23.7%), Pseudomonas spp. (8.2%), and Streptococcus pyogenes (7.2%). Gram-positive bacteria were mostly (60%) found sensitive to vancomycin, azithromycin, gentamicin, imipenem, cefixime, and ceftriaxone in this study. Among the Gram-negative bacteria, Escherichia coli (>60%) showed sensitivity to cefixime, azithromycin, cefuroxime, ceftriaxone, cefotaxime, gentamycin, and ceftazidime. Conclusions: The diversity of isolated bacteria and their susceptibility patterns signify a need to implement a proper infection control strategy, which can be achieved by carrying out antibiotic sensitivity tests of the isolates.

Globally, antibiotic resistance in bacteria isolated from neonatal sepsis is increasing. In this cross-sectional study conducted at a medical college teaching hospital in Nepal, we assessed the antibiotic resistance levels in bacteria cultured from neonates with sepsis and their in-hospital treatment outcomes. We extracted data of neonates with sepsis admitted for in-patient care from June 2018 to December 2019 by reviewing hospital records of the neonatal intensive care unit and microbiology department. A total of 308 neonates with sepsis were admitted of which, blood bacterial culture antibiotic sensitivity reports were available for 298 neonates. Twenty neonates (7%) had bacteriologic culture-confirmed neonatal sepsis. The most common bacterial species isolated were Staphylococcus aureus (8), followed by coagulase-negative Staphylococcus (5). Most of these bacteria were resistant to at least one first-line antibiotic used to manage neonatal sepsis. Overall, there were 7 (2%) deaths among the 308 neonates (none of them from the bacterial culture-positive group), and 53 (17%) neonates had left the hospital against medical advice (LAMA). Improving hospital procedures to isolate bacteria in neonates with sepsis, undertaking measures to prevent the spread of antibiotic-resistant bacteria, and addressing LAMA’s reasons are urgently needed.

First Choice

Cow’s milk containing pathogenic bacteria is an important threat to the consumers. The objectives of the present study were to identify the bacterial agents of public health importance in milk samples (n=35) of different locations and to determine their sensitivity to different antibiotics. The milk samples were collected and transported aseptically and subsequently allowed for culture in bacteriological media, Gram’s staining and biochemical tests for the identification of bacterial species. The bacteria identified were Staphylococcus aureus, Escherichia coli and Salmonella typhi, and their prevalence, in case of vendor milk specimens (n=28), were 96.43%, 53.57% and 35.71% respectively, and of brand milk specimens (n=7), were 42.86 %, 28.57% and 0%, respectively. This suggests that cautionary measures should be taken for quality milk production and consumption. The antibiotic sensitivity test was done by disc diffusion method and the average inhibition zones, in case of Staphylococcus aureus, were 32 mm for oxytetracycline, 26 mm for amoxicillin, 35 mm for ciprofloxacin, 27 mm for cefotaxime, 30 mm for ceftriaxone, 30 mm for azithromycin, and 26 mm for erythromycin; in case of Escherichia coli, were 5 mm for oxytetracycline, 9 mm for amoxicillin, 22 mm for ciprofloxacin, 30 mm for cefotaxime, 31 mm for ceftriaxone, 15 mm for azithromycin, and 0 mm for erythromycin; in case of Salmonella typhi., were 25 mm for oxytetracycline, 24 mm for amoxicillin, 38 mm for ciprofloxacin, 31 mm for cefotaxime, 34 mm for ceftriaxone, 24 mm for azithromycin, and 0 mm for erythromycin. Therefore, ciprofloxacin and ceftriaxone may be the antibiotics of first choice, and cefotaxime and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.Asian J.

The Impact

Abstract Different methodologies have been developed throughout the years to identify environmental microorganisms to improve bioremediation techniques, determine susceptibility profiles of bacteria in contaminated environments, and reduce the impact of microorganisms in ecosystems. Two methods of bacterial biochemical identification are compared and the susceptibility profile of bacteria, isolated from residential and industrial wastewater, is determined. Twenty-four bacteria were retrieved from the bacteria bank of the Environmental Microbiology Laboratory at the Institute of Biology (IB) of the Universidade Federal de Pelotas, Pelotas, Brazil. Bacteria were identified by conventional biochemical tests and by the VITEK ®2 automated system. Further, the susceptibility profile to antibiotics was also determined by the automated system. Six species of bacteria (Raoutella planticola, K. pneumoniae ssp. pneumoniae , Serratia marcescens, Raoutella sp., E. cloacae and Klebsiella oxytoca) were identified by conventional biochemical tests, while three species of bacteria (K. pneumoniae ssp. pneumoniae, S. marcescens and K. oxytoca ) were identified by VITEK®2 automated system. VITEK ®2 indicated agreement in 19 (79.17%) isolates and difference in five (20.83%) isolates when compared to results from conventional biochemical tests. Further, antibiotic susceptibility profile results showed that all isolates (100%) were resistant to at least one out of the 18 antibiotics tested by VITEK®2. Thus, no multi-resistant bacteria that may be used in effluent treatment systems or in bioremediation processes have been reported. Results indicate VITEK ® 2 automated system as a potential methodology in the determination of susceptibility profile and identification of environmental bacteria.

Aeromonas hydrophila is an opportunistic microorganism. It is a secondary biological agent that contributes to the occurrence of fish diseases and its deterioration. This research was undertaken to determine the prevalence of A. hydrophila in some freshwater fishes collected from three different fish markets of Dhaka City and to test their antibiotic susceptibility. Total bacterial count and total aeromonas on different aeromonas selective media were enumerated using serial dilution technique. Bacterial isolates were characterized to identify A. hydrophila using biochemical tests and with comparison to reference strain (ATCC 7966). The lowest Aeromonas count was detected to be 2.83±0.40×102 cfu/g in Anabas testudineus and the highest was 1.03±0.153×103 cfu/g in Oreochromis mossambicus. On market basis highest aeromonas count was found in Anando Bazar (8.10±1.09×102 cfu/g) and lowest in Hatirpool Bazar (5.63±0.90×102 cfu/g) with no significant difference. Maximum susceptibility to amikacin and gentamicin was observed whereas all of the isolates were found resistant to a commonly used antibiotic amoxycillin. The obtained results point that antimicrobial susceptibility was more or less similar regardless of the origin of the samples collected. All the fishes investigated in this study contained A. hydrophila in their different organs.

The use of earphones has increased in recent times throughout the world especially among the different level of students such as school, college or university who have a higher tendency of sharing these among them. Unlike airline headsets, headphones and stethoscope ear-pieces, ear phones are often shared by multiple users and can be a potential medium for transmission of pathogens, which can give rise to various ear related infections. The objective of this study was to detect the pathogenic bacteria from the ear-phones used by the students of Stamford University Bangladesh. A total of 16 ear-phone swabs were collected by sterile cotton swabs. The swabs were inoculated onto blood agar and incubated aerobically overnight at 37oC. Microscopic observation and standard biochemical tests were performed to confirm the identification of all the bacterial isolates. Six presumptively identified Staphylococcus spp. (38%) were tested against six different types of antibiotics following Kirby-Bauer disk diffusion method. Isolates were found to be 84% resistant against Cotrimoxazole and demonstrated 100% sensitivity to Vancomycin and Ciprorofloxacin. The findings of this study suggest the users to disinfect their respective ear phones and not to exchange them as they may act as a potential source to transfer pathogenic and antibiotic resistant bacteria among the ear phone users.

Foodborne illness is generally caused after consumption of food contaminated with pathogenic microorganisms. Food contamination often caused by contact with tabletops or food handling surfaces where the pathogenic microbes are present due to unhygienic condition of people working there and the overall environment of the food serving area. In current study, four areas (local restaurants, fast food shops, university canteens and hospital canteens) were selected for collection of swab sample (per cm2 area) from the tabletops. Five samples from each area were taken for further studies. After microbiological analysis we found ten different types of bacteria (Esherichia coli, Klebsiella pneumonia, Klebsiella oxytoca, Corynebacterium xerosis, Staphylococcus aures, Salmonella spp., Proteus mirabilis, Enterobacter aerogenes, pseudomonas aeruginosa and Alcaligenes fecalis) which are already considered to be pathogenic bacteria causing different health issues in immune-compromised and also in healthy consumers. These bacteria were then subjected to antibiotic sensitivity test using ten antibiotics-Vancomycin (30 µg), Cotrimoxazol (30 µg), Azithromycin (15 µg), Gentamicin (10 µg), Amoxycillin (10 µg), Cephradine (30 µg), Ceftriaxone (30 µg), Cefuroxime (30 µg), Cefoxitin (30 µg) and Tetracycline (30 µg). Bacterial isolates collected from university and hospital canteens showed most resistance towards these antibiotics. Strict maintenance of proper sanitation and hygiene starting from personal aspects to the overall environment of food handling service should be maintained to reduce the food contamination and foodborne disease.
