Incidence and Prevalence of Enterococcal species, Isolated from Various Clinical Samples, in Tertiary Care Hospital at Darbhanga, Bihar
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 12
Abstract
Objective: The aim of present study was to evaluate the incidence and prevalence of Enterococci species in different clinical samples. Materials and Methods: A total of 17162 clinical samples (Urine, Pus, Blood, Wound swab, peritoneal fluid, etc.) were received from different OPD and IPD to our department. All the samples were processed with standard procedure. Isolation and Identification of Isolates were done on the basis of Grams staining, motility, blood agar, mac-conkeys agar, nutrient agar, bile aesculin hydrolysis tests, PYR test and salt tolerance test. Results: Out of 17162 clinical samples, a total of 354 (2.06%) Enterococci isolates were isolated. Enterococci were more frequently isolated from urine (60.46 %) followed by pus (19.20%) and wounds (12.72%). Among the 354 isolates of Enterococci, only 201 (56.78%) isolates represented pure cultures of Enterococci, whereas 153 (43.22%) grew along with other Gram positive or Gram negative organisms of which majority were Pseudomonas aeruginosa, Escherchia coli, Proteus species and Staphylococcus aureus. The majority of the isolates were E.faecalis 83.61%, while E.faecium accounted for 16.39 %. Conclusion: The incidence and prevalence of enterococcal urinary tract infection is increasing due to the result of use of catheterization and irrelevant, improper, under dose antimicrobials. So consider the enterococcal species as essentially pathogenic as they are isolated in pure culture from various clinical specimens.
