Acinetobacter A. calcoaceticus

Description and Significance

Acinetobacter calcoaceticus is a soil bacterium. It is located in sewage and soil and is capable of causing nosocomial infections.

Despite being regarded nonpathogenic in most cases, Acinetobacters are causal agents of nosocomial infections, particularly in the elderly.

Genome Structure

Acinetobacter calcoaceticus has a size of 0.9 - 1.6 micrometers by 1.5 - 2.5 micrometers. It has a chromosome of 4,110,074 base pairs and a plasmid of 5,920 base pairs. It has a rod shape.

Cell Structure, Metabolism and Life Cycle

The Acinetobacter calcoaceticus may use a broad variety of organic substances as its only source of carbon and energy. It is a Gram-negative nonpathogenic bacteria, holds considerable potential in bioremediation. It was initially isolated due to its capacity to use diesel as its only carbon source.

Ecology and Pathogenesis

The Acinetobacter calcoaceticus can be found in soil and sewage. While it is usually found in dirt, it may also be detected in and collected from human specimens, interstitial regions, axillae, toe webs, pharynx, and various healthy people's secretions. They form 25% of the skin flora in normal people. Colonization of the digestive system has been observed in both newborns and adults. Rectal Acinetobacter colonization carries the danger of translocation.
