Milk is such a food which can meet almost all nutritional needs of human lives. Raw or unprocessed milk supports the growth of wide variety of microorganisms. The major interests of this study were examining the microbial quality of raw milk collected from different locations of Jessore city in Bangladesh and determining antibiotic susceptibility pattern of some isolated bacteria. To do so, 12 raw milk samples were collected from different areas of Jessore city. Microbial analysis comprised of enumeration of TVC (total viable count), TCC (total coliform count) and TSC (total staphylococcal count). The highest TVC, TCC and TSC were 1.95x109 CFU/ml, 2.5x107 CFU/ml and 1.02x107 CFU/ml respectively. Prevalent bacterial populations were Klebsiella spp., Enterobacter spp., Shigella spp. Staphylococcus spp., Escherichia coli and Citrobacter spp. In order to observe the antibiotic susceptibility pattern, the antibiotic sensitivity test was performed for some randomly selected isolates of E. coli and Klebsiella spp. More than 90% isolates of Klebsiella spp. were found to be resistant against Erythromycin whereas more than 90% isolates were sensitive against Imipenem. On the other hand, 100% E. coli isolates were observed as resistant against Erythromycin and in case of Trimethopreme 100% isolates were sensitive. Multidrug resistance pattern was also found. These results suggest the necessity of hygienic practices during handling, processing and post-processing of raw milk to improve the microbiological quality and safety of raw milk.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23723Bangl.

Abstract Background Worldwide, come out and dissemination of Extended-spectrum beta-lactamases (ESBLs) producing Enterobacteriaceae has been warning the efficacy of antibiotics to treat an infection. Hospital wastewaters were a reservoir of such kind of resistant bacteria. Currently, the predominant antibiotics used for the treatment of hospitalized patients infected by Gram negative bacteria are the 𝛽-lactam antibiotics. So it is an important source to investigate the magnitude of ESBLs producing bacteria and their antimicrobial susceptibility pattern. The aim of this study was to determine the occurrence of ESBLs producing Enterobacteriaceae (ESBLs-pE) and their antibiotic susceptibility pattern in wastewater released from five governmental hospitals in Addis Ababa, Ethiopia. Method A cross-sectional study was carried out from April 1 to May 31, 2020. A total of 100 wastewaters were collected from five governmental hospitals in Addis Ababa using a grap-sampling technique. All Enterobacteriaceae were screened for ESBLs production using cefotaxime and ceftazidime as per 29th CLSI guideline. Each screen positive for ESBLs production was confirmed by the combination disk method (CDT) and their antibiotic susceptibility pattern were done using the Kirby-Bauer disk diffusion method on Muller Hinton agar (MHA). Data were entered and summarized using SPSS version 20 software. Results Of all Enterobacteriaceae, 48.3% were confirmed ESBLs-pE. The highest ratio of ESBLs-PE was observed in adult ward (66.7%) and laundry unit effluent (58.8%). The highest ESBL producers were E. coli (21.8%) and K. pneumoniae (4.8%). The most elevated resistance level of ESBL producer were observed to cefotaxime (95.8%) and amoxacilline/clavunalate (93%). 64% of tested Enterobacteriaceae isolates were multi drug resistant (MDR). Conclusion Higher magnitude of MDR and ESBLs-pE were present in the hospital wastewater. Majority of them were in adult ward and laundry unit effluents. The most frequent ESBLs-pE was among E .coli and K. pneumoniae. Hence, Consistent infection prevention and control procedures should be in practice at each ward/unit.

Antibiotics to treat dental caries infection are routinely prescribed which led to the increased resistance against bacteria. The purpose of this investigation was to perform antibiotic susceptibility tests on a panel of pathogenic bacteria isolated from dental caries infection. Bacteria were isolated from caries site of patients and identified at the species level. Each of 150 species of bacteria was tested for antibiotics susceptibility to a five antibiotics using Etest. The antibiotics used were Amoxicillin, Cloxocillin, Erythromycin, Tetracycline and Penicillin‐V. The obtained resistance percentage for each antibiotic were Penicillin V: 72/150 (48%), Tetracycline: 99/150 (66%), Amoxicillin: 135/150 (90%), Cloxocillin: 117/150 (78%), and Erythromycin: 90/150 (60%) (Table 1). In case of combinatorial antibiotic exposure, the resistance percentage of Penicillin V/Amoxicillin and Amoxicillin/ Erythromycin was 39/150 (26%), and 45/150 (30%) respectively. The study has well demonstrated the clinical picture of antibiotic resistance and susceptibility pattern of bacteria causing dental caries. The obtained comprehensive data will allow investigating the spatial distribution of pathogenic, antibiotic resistant bacteria among dental caries patients which further may help into development of novel diagnostic and treatment approaches for the same.

Current Scenario

Neonatal sepsis is one of the leading causes of neonatal mortality in developing countries. Neonatal sepsis can be classified into two subtypes depending upon onset of symptoms- before 72 hours of life (early-onset neonatal sepsis—EONS) or later (late-onset neonatal sepsis—LONS). Bacteriological profile and antibiotic susceptibility pattern in neonatal septicemia are changing time-to-time and place-to-place. This study is aimed to know the current scenario of neonatal septicemia and antibiotic susceptibility pattern for determining effective treatment, hence reducing burden of antibiotic resistance.This is a Retrospective study. Data was collected from Bacteriology lab, PDUMC Rajkot (May 2020 – May 2021). Blood cultures were performed on suspected neonates. Both BACTEC and conventional methods were used. Organisms were isolated by standard microbiological protocols and antibiotic sensitivity was performed by Kirby-Bauer disc diffusion method as per CLSI- 2020/2021 guidelines. Total 1402 samples were screened. 326 were positive (23.25%). 214(65.64%) were male and 112(34.36%) were female. CONS (32.21%) was found to be the predominant pathogen followed by Klebsiella (19.63%), Staphylococcus aureus (18.10%), E. coli (15.95%), Acinetobacter (12.27%) and Enterococcus spp. (1.84%). EONS was seen in 195(59.82%) cases and LONS was seen in 131(40.18%) cases. Gram-negative bacteria are predominant in EONS (76.28%) and gram-positive bacteria is predominant in LONS (64.12%). Gram negative isolates are mostly susceptible to Meropenem, Piperacillin-tazobactam, Cefepime, Ceftazidime. Gram positive isolates mostly showed sensitivity to Vancomycin, Linezolid.Multi-drug resistant organism are emerging in neonatal septicemia. Strict antibiotic stewardship should be practiced to avoid the upcoming treatment difficulties.

Background: The genus Klebsiella of Enterobacteriaceae family is ubiquitous in nature. They cause many nosocomial infections like pneumonia, urinary tract infections, wound infections, bacteremia and septicemia. Multidrug resistance is seen in Klebsiella which serves as the most common cause of increased morbidity and mortality. This study reveals the prevalence and antibiotic sensitivity pattern of Klebsiella species from various clinical samples. The primary objectives are as follows: To isolate and characterize Klebsiella species from various clinical samples. To study the antibiotic susceptibility pattern of Klebsiella isolates.Methods: This prospective study was conducted in our tertiary care hospital during the period from August 2019 to October 2019. A total of 3521 samples were tested during this period. The samples include blood, sputum, urine, and pus.Results: Out of the total samples tested,1106 samples were showing the growth of the organisms. Among this,351 were identified as Klebsiella species and the highest rate of isolation of Klebsiella species is from the sputum sample and also the same was reported high in medical wards. The study also shows that the isolation of Klebsiella species shows male preponderance when compared to females. The antibiotic sensitivity pattern was done by Kirby-Bauer's disc diffusion method and the sensitivity was noted to be higher to amikacin and ciprofloxacin.Conclusions: Thus, this study shows the prevalence rate of Klebsiella species and sensitivity pattern of Klebsiella, which may help select appropriate antibiotics and prevent overuse and misuse of antibiotics.

Background: Group B streptococcus (GBS) is one of the important cause of early onset neonatal sepsis in developed countries leading to increased neonatal morbidity and mortality. Penicillin and Ampicillin are the drugs of choice for prevention of GBS infections. Antibiotic resistance amongst GBS isolates is an emerging health problem affecting neonates. Hence, this study was performed to determine the antibiotic susceptibility pattern of Group B Streptococcus (GBS) in a population of pregnant women.Methods: A prospective study was done to screen pregnant women for vaginal and rectal GBS colonization during their regular visits to antenatal clinic. Todd-Hewitt broth, an enrichment medium for GBS was used for isolation. The antibiotic susceptibility pattern of the isolates were studied.  Results: A total of 300 pregnant women were screened for GBS colonization. GBS colonization rate in our study was 2.3%. The antibiotic susceptibility pattern of the isolates revealed that none of the isolates were resistant to penicillin or clindamycin, while resistance was noted to erythromycin (14.3%) and   tetracycline (71.4%).Conclusions: GBS continues to remain sensitive to Penicillin which is the drug of choice for prevention and treatment of GBS.  Consistent surveillance of antibiotic sensitivity pattern of GBS as well as for other organisms implicated in new born sepsis and maternal infections is required to formulate guidelines for prevention and treatment.

Background: Muscle foods, notably red meat, poultry meat, and fish are the first choice of animal source food with adequate protein for human. The present study was undertaken to analyze the load and antibiotic susceptibility pattern of microorganisms in muscle foods sold in Akure, Southwest Nigeria. Methods: Hundred muscle food samples, including meat and fish were collected from different locations (A-E) of Akure, Nigeria and examined microbiologically using cultural techniques, biochemical tests, and analytical profile index. Antibiotic susceptibility patterns were also determined in isolated microorganisms from muscle foods against different antibiotics. Data were analyzed using SPSS software version 17.0. Results: The highest (p<0.05) total viable bacterial count (8.3×106 CFU/g) were obtained from pork, including with 6.0×105 CFU/g for Staphylococcus and 5.8×105 CFU/g for Salmonella-Shigella. Mackerel collected from location D (Kings market) had the highest (p<0.05) bacterial count of 9.97×105 CFU/g, followed by 8.57×105 CFU/g, and 7.03×105 CFU/g in locations C and E, respectively. Low fungal counts were recorded ranged from 1.0×102 to 1.30×102 spore forming unit/g. The highest (p<0.05) occurrence of 26.50% was observed for Escherichia coli. The isolated microorganisms displayed varying degree of resistance (33.3 to 100%) to commonly used antibiotics. Conclusion: The microorganisms found in muscle foods from Akure, Nigeria could be considered as result of poor hygiene of the retailers or handlers. Also, presence of the multidrug resistant bacteria in muscle foods distributed in this region could pose a serious risk factor to public health.

Global Public Health Problem

Enteric fever continues to be a major global public health problem, predominantly in the developing countries, including Bangladesh. Mortality rates due to enteric fever can be reduced from 30% to <1% by providing effective antimicrobial therapy which is facing challenges due to emerging antimicrobial resistance. The changing trend of antibiotic susceptibility pattern of Enteric fever from pre-antibiotic era through susceptible antibiotics, then multidrug resistance (MDREF) followed by re-emergence of sensitivity to some older resistant antibiotics pose therapeutic challenges for the physicians. The purpose of this review article is to compare the antibiogram of Salmonella isolates of different recent studies and analyzing the changing trend of antibiotic resistance pattern for further successful management. This may also enable planning of antibiotic recycling wherever feasible. J MEDICINE JAN 2020; 21 (1) : 51-54
