Enterococci, especially Enterococcus faecalis and faecium, have emerged as an important nosocomial pathogen and represent a serious threat to patients with impaired host defenses. E. faecalis and faecium are part of the normal intestinal microbial flora of poultry and man under most conditions, they are considered as an opportunistic pathogen. In the current study, an investigation of Enterococcus spp. isolated from poultry feces and their antibiotic susceptibility pattern was studied, due to the worldwide attachment with poultry by human being. Samples were collected from different sites of Allahabad, India, 80 samples collected screened for the presence of E. faecalis and E. faecium and identified based on cultural and biochemical characteristics. Thirty-five isolates were identified as E. faecalis (57.37%), while 26 were E. faecium (42.62%). The pathogens isolated were tested for their susceptibility toward 10 different commonly prescribed antibiotics. Most of the isolates showed resistance toward antibiotics under study. E. faecalis strain suggested a higher percentage of possibility of infection estimated by 15% in comparison with E. faecium as it was found to be less in a screening. The high resistance rate also indicates the negative impact of the antibiotic therapy. To evaluate the extent of transmission and impact of such transmission on the effectiveness of the antibacterial use in human medicine, further study is imperative. Periodic monitoring of antibiotic resistance pattern to detect any change in it would be necessary for the effective treatment against these pathogens. Enterococci revealed an alarming rate of resistance to the standard antimicrobial agents used for therapy and raised MIC values to vancomycin. The importance and infection control were stressed.

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.

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

Abstract OBJECTIVES: Gram-positive infections such as those by Staphylococcus aureus have contributed to the disease burden by increasing the morbidity and mortality rates in India. This study aims to determine the prevalence and the antibiotic susceptibility pattern of Gram-positive pathogens at a tertiary care hospital, Mumbai, Maharashtra, India. MATERIALS AND METHODS: This retrospective cross-sectional study was carried out from January, 2015 to December, 2017, at a tertiary care hospital in Mumbai, India. The clinical isolates were cultured, and identification was done using Vitek 2 culture system. The antibiotic susceptibility testing was done as per the Clinical Laboratory Standard Institute guidelines. RESULTS: Out of 2132 (29%) Gram-positive isolates, S. aureus (49%) was the most common encountered pathogen, followed by Enterococcus spp. (24.5%) and coagulase-negative Staphylococcus (16%). Majority of the S. aureus were observed in patients with skin and soft-tissue infections (61.2%) followed by those suffering from respiratory (41%) and bloodstream infections (35%). Among the infections caused by S. aureus, the prevalence of methicillin resistance was 30%. While the MRSA isolates showed lower sensitivity toward co-trimoxazole (39%), clindamycin (30%), erythromycin (23%), and ciprofloxacin (10%), they showed higher susceptibility to linezolid (98%), vancomycin (98%), and teicoplanin (98%). All the isolates were found to be sensitive to daptomycin and tigecycline. While vancomycin-resistant enterococci (VRE) formed 7.5%, the linezolid-resistant enterococcus species was as high as 4.1%. CONCLUSION: The study showed a high prevalence of MRSA and VRE, thereby emphasizing the increasing antimicrobial resistance pattern of the Gram-positive pathogens. Therefore, there is an urgent need for novel antimicrobial stewardship to restrict the ongoing resistance rate among the isolates.

The Relationship

The study was conducted in Kathmandu valley to investigate the relationship between the use of antibiotic and the development of the resistant form of Escherichia coli (E.coli), which were isolated from faecal waste of poultry farm. Out of 30 samples investigated, 20 samples were found to be E.coli positive. It was further investigated that the resistance pattern for the isolates of E.coli from poultry farm was tetracycline (100%), penicillin (100%), erythromycin (100%), amoxicillin (90%) and chloramphenicol (60%).
