Acinetobacter baumannii- Pathogenicity and Clinical Features

Acinetobacter baumannii- Pathogenicity and Clinical Features Acinetobacters are strictly aerobic, oxidase-negative, plump gram-negative coccobacilli which are ubiquitous saprophytes, recovered in nature and in the hospitals. They are opportunistic pathogens that cause infections in the respiratory tract, urinary tract, and wounds; they also cause septicemia. Acinetobacter is subdivided into two groups: glucose oxidizing species ( A. … Read more Acinetobacter baumannii- Pathogenicity and Clinical Features

Acinetobacter baumannii- Lab Diagnosis, Treatment and Prevention

Laboratory Diagnosis The diagnosis of Acinetobacter infection is made by the growth of Acinetobacter from a patient specimen (eg, sputum, blood, cerebrospinal fluid) in the setting of other clinical findings that suggest an infection at that site. Since Acinetobacter colonization is common and treatment difficult and potentially associated with substantial toxicity, the distinction between colonization and infection, with treatment … Read more Acinetobacter baumannii- Lab Diagnosis, Treatment and Prevention
