A Study of Virulence Factors and Drug Resistance Pattern in Escherichia coli Isolated from Extra Intestinal Infections in a Tertiary Care Teaching Hospital, Chinakakani, Guntur, Andhra Pradesh, South India

Tuberculosis is the leading cause of death in Nepal. Failure in early detection anddrug resistance are two most important problems in treatment and cure of thetuberculosis. The objective of the study was to assess the drug resistance pattern inMycobacterium tuberculosis isolated in Tribhuvan University teaching Hospital. Morethan 85% of isolates were sensitive to all the four drugs and 5.5% of isolates weremultidrug resistant. The drug resistant isolates were obtained more frequently frompreviously treated patients. More extensive studies should be carried out by independentorganizations to collect more representative data on drug resistance tuberculosis.Key Words: Tuberculosis, drug resistance and surveillance.

AbstractIntroductionSARS-CoV2 which is a corona virus also predisposes patient to secondary bacterial infection by various mechanisms like-damaging the respiratory epithelium, profoundly affecting the innate and adaptive immunity, antagonising Interferon responses that enhance bacterial adherence, colonisation and invasion to respiratory tissue. In addition, prolonged hospital stay, invasive therapeutic devices, widespread use of empiric antibiotics and most importantly use of immune-suppressants like Steroid or Tocilizumab further increases the chances of bacterial infection. As opposed to this concept-physical distancing, frequent hand washing and use of gloves and protective gear by the healthcare workers also diminishes the chance of secondary bacterial infection. The present study is done to delineate the bacteriological profile, infection site predisposition or to gain knowledge on antibiotic sensitivity pattern.MethodRetrospective data will be analyzed from June 2020, when the first COVID wave came to June 2021, corresponding to second COVID wave. The present study is a pilot study before collecting and analyzing the whole data Only those samples which were positive for bacterial isolates were randomly selected and the COVID status and drug resistance patterns were checked.Results and discussionThe most common organism found was Klebsiella. Acinetobacter was also found in few patients. But most striking finding was that COVID positive patients showed higher incidence of antibiotic resistance with Acinetobacter. Though E Coli was also found commonly in COVID positive patients, they were not drug resistant.ConclusionMDR infections are common in COVID patients. Acinetobacter and Klebsiella are prone to develope MDR infections. While E.Coli is also common in COVID patients, chance of drug resistance is less among them.
