AbstractSerratia rubidaea a member of the Enterobacteriaceae family, is a Gram-negative opportunistic pathogen, known to survive harsh environmental conditions and responsible for hospital associated infections. Specifically, S. rubidaea can withstand desiccation and survive on hospital surfaces and equipments as well as have acquired antimicrobial resistance determinants for different commercial antibiotics. The expansion of this multidrug resistant pattern suggests that the treatment of S. rubidaea infections will become increasingly difficult in near future. Although some measures were taken to control this species, an inhibition mechanism is remaining unknown. To design effective means to control the dissemination of S. rubidaea, an in-depth analysis is required. In the present study, one possible candidate was isolated from the soil of Sundarban Mangroove Forest (Bangladesh) that has important physiological effects to inhibit this pathogenic bacterium. The bacterial isolate was initially identified as Bacillus amyloliquefaciens subsp. amyloliquefaciens using BIOLOG™ identification system and confirmed to be B. amyloliquefaciens strain through 16S rDNA sequence analysis. The growth and antagonistic activity of this potential strain was shown to be stable under wide range of pH, temperature and salinity (NaCl). Moreover, the novel B. amyloliquefaciens isolate can also inhibit Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and other pathogenic bacteria. These results suggest that B. amyloliquefaciens might have potential antimicrobial properties and further research is required for future use of this bacterium as biological controls of S. rubidaea or development as new drugs for pathogenic bacteria.

INTRODUCTION: Enteric fever includes typhoid and paratyphoid fever. Peak incidence is seen in children 5–15 years of age; but in regions where the disease is highly endemic, as in India, children younger than 5 years of age may have the highest infection rates. There are about 22 million new typhoid cases occur each year. Young children in poor, resource limited areas, who make up the majority of the new cases and there is a mortality figures of 215,000 deaths annually. A sharp decline in the rates of complications and mortality due to typhoid fever is observed as a result of introduction of effective antibiotic therapy since 1950s. MDR-ST became endemic in many areas of Asia, including India soon after multidrug-resistant strains of Salmonella enterica serotype typhi (MDR-ST) that were resistant to all the three first-line drugs then in use, namely chloramphenicol, amoxycillin and co-trimoxazole emerged in early 1990s. MATERIAL AND METHODS: Only blood culture or bone marrow culture positive cases were included. The patients with culture isolated enteric fever were included in the study. Antimicrobial susceptibility testing was carried out by disk diffusion method using antibiotic discs. The analysis of the antimicrobial susceptibility was carried out as per CLSI interpretative guidelines. RESULTS: A total of 82 culture positive cases were included in the present study. 80 culture isolates were from blood culture and 2 from the bone marrow culture. Salmonella entericasubspecies enterica serovartyphi (S typhi) was isolated from 67 (81.70%) patients while Salmonella enterica subspecies entericaserovarparatyphi (S paratyphi A) was isolated from 13 (15.85%) cases and 2 (2.44%) were Salmonella enterica subspecies entericaserovarschottmuelleri (S paratyphi B). Of the 82 cases 65(79.3%) isolates were resistant to ciprofloxacin, 17 (20.7%) were resistant to nalidixic acid, one (1.2%) case each was resistant to Cefotaxime and ceftriaxone, 2 (2.4%) were resistant to chloramphenicol, 10 (12.2%) were resistant and to cotrimoxazole 3 (3.7%) were resistant. CONCLUSION: In a culture positive cases 65(79.3%) isolates were resistant to ciprofloxacin and 17 (20.7%) were resistant to nalidixic acid. Multidrug resistant isolates were 65(79.3%).

Background: The rate of multidrug-resistant organisms (MDRO) colonisation in dialysis populations has increased over time. This study aimed to assess the effect of contact precautions and isolation on quality of life and mood for haemodialysis (HD) patients colonised with MDRO. Methods: Patients undergoing facility HD completed the Kidney Disease Quality of Life (KDQOL–SFTM), Beck Depression Inventory (BDI) and Personal Wellbeing-Index Adult (PWI-A). Patients colonised with MDRO were case-matched by age and gender with patients not colonised. Results: A total of 16 MDRO-colonised patients were matched with 16 controls. Groups were well matched for demographics and co-morbidities, other than a trend for older dialysis vintage in the MDRO group [7.2 years (interquartile range 4.6–10.0) compared to 3.2 (1.4–7.6) years, p=0.05]. Comparing MDRO-positive with negative patients, physical (30.5±10.7 vs. 34.6±7.3; p=0.2) and mental (46.5±11.2 vs. 48.5±12.5; p = 0.6) composite scores were not different between groups. The MDRO group reported poorer sleep quality (p=0.01) and sleep patterns (p=0.05), and lower social function (p=0.02). BDI scores were similar (MDRO-positive 10(3.5–21.0) vs. MDRO-negative 12(6.5–16.0), p=0.6). PWI-A scores were also similar in both groups; however, MDRO patients reported lower scores for “feeling safe”, p=0.03. Conclusion: While overall scores of quality of life and depression were similar between groups, the MDRO group reported poorer outcomes in sleep and social function. A larger cohort and qualitative interviews may give more detail of the impact of contact precautions and isolation on HD patients. The necessity for contact precautions for different MDRO needs consideration.
