Prevalence of multidrug-resistant Acinetobacter baumannii in endotracheal aspirate samples: Experience at a tertiary hospital

The emergence of resistance to multiple antimicrobial agents in pathogenic bacteria poses a significant public health threat because few or no effective antimicrobials are available for infectious diseases. is a major cause of device-associated infections that pose a serious threat to critically ill patients. Resistance patterns are thought to result in very limited treatment options and high mortality. We examined the prevalence of in endotracheal aspirates samples and explored their antibiotics susceptibility. To determine the value of routine endotracheal aspirate cultures performed prior to the onset of the likely onset of ventilator-associated pneumonia (PVAP) in predicting pathogenic microorganisms and susceptibility to their antibiotics Patients admitted to the ventilatory intensive care unit were tested daily, and endotracheal aspirated (ET) specimens from suspected patients were sent to a microbiology laboratory for culture and sensitivity measurements. Of the 52 patients, only twenty five (48%) developed PVAP. Endotracheal aspirate cultures were positive in all PVAP cases. The most commonly isolated bacteria was 14 (56%), followed by 6 (24%) and 4 (16%). Almost all isolates of are multidrug resistant (MDR). ICU stays greater than 16 days were observed for the pathogen . We believe that multidrug-resistant is a widespread epidemic, leading to high mortality, long ICU stays, and a difficult case for ICU physicians. Further prospective studies are needed to tackle this threat
