ABSTRACT
Background:A novel corona virus known as severe acute respiratory syndrome corona virus 2 was first reported in Wu- han city of China.The spectrum of clinical presentation of COVID 19 is highly variable,infections range from being asymp- tomatic to severe viral pneumonia with respiratory failure often leading to death.some patients found to be additionally infected with a secondary bacterial infection with 50% fatalities due to the COVID 19 caused by untreated or untreata- ble secondary bacterial infection in the lungs.Secondary bacterial infections develop in patients during or after initial infection. Methods:The study was conducted in Microbiology laboratory from the samples received from Government general hospital, Kurnool medical college,Kurnool.Patients were investigated for detection of secondary bacterial infection of respiratory tract using the conventional methods.Cough out sputum was collected and cultured on different media to support the growth of the bacteria. After incubation,formed colonies on the media were identified using gram staining and other biochemical tests.Antimocrobial susceptibility testing then done on isolated organisms according to standard CLSI guidelines. Results:Among 60 samples obtained, commonest organisms isolated are Staphylococcus aurues (35%), Streptococcus pneumonia (23%),Klebsiella (16%),Pseudomonas (8%),Acimetobacter (6%). Antibiotic susceptibility done in order to see multidrug resistant organisms. Conclusions:Secondary bacterial infections play a critical role in the morbidity and mortality rates of patients initially falling ill with pulmonary viral disease. Need for the study is to isolate the organism causing secondary bacterial infec- tion, there antibiotic susceptibility in order to give appropriate treatment, to avoid drug resistance and to improve the quality of life.
