Diagnosis of Hospital-Acquired Infections

Diagnosis of Hospital-Acquired Infections

Diagnosis of hospital-acquired infections is made by routine bacteriological methods, such as direct demonstration of microorganisms in specimens by microscopy, isolation by culture, and testing bacterial isolates for their antibiotics sensitivity pattern. The specimens are usually sampled from possible sources of infections, such as environment, inanimate objects, water, air, food, hospital personnel, etc. The source of infection may be traced by performing phage typing, bacteriocin typing, biotyping, or molecular typing.
