PREVALENCE OF ANTIBOIOTIC RESISTANT RALSTONIA SPP AND OTHER EXOTIC GRAM NEGATIVE ORGANISMS IN HOSPITAL ANIMATE AND INANIMATE SOURCES AND ITS RELATIONSHIP WITH NOSOCOMIAL INFECTIONM. REENAA, D. GAYATHRI AND S. LALITHA KAMESWARIAbstract Infections acquired by the patient during hospital stay are generally considered as nosocomial infections. Rise in nosocomial infections are due to various factors such as crowded hospital environment, sub-optimal sanitary conditions and increasing bacterial resistance. Less common gram negative pathogens can play significant role in nosocomial infections during prolonged hospital stay. These organisms can cause critical illness especially in immunocompromised cases. In the present study, samples from patient and environmental sources including hospital equipment were collected and microbiologically analyzed to understand the source and transmission. In the present study based on the study premise, the clinical sample microbiological analysis was limited to gram negative bacilli. In the clinical samples besides the rare bacilli viz., Ralstonia sp., several common gram negative pathogens including, Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Proteus vulgaris, Citrobacter sp, Enterobacter sp, and Klebsiella sp were isolated and identified. These pathogens were found to be resistant to most common antibiotics employed in treating UTI.
