title: Human Listeriosis Presenting as Breast Abscess: Report of a Rare Case.
abstract: An abscess is defined as a collection of pus in various tissues of the body including skin and other organs. Abscesses most commonly are formed on the skin under the armpits, groin areas, and rectal areas. Most abscesses involve microbial infections with few remaining sterile. The treatment of abscesses includes both medical and surgical intervention. In the era of multidrug resistance, isolation and identification of the causative microbe and testing for antimicrobial susceptible patterns assume greater significance for the better management of patients, thereby reducing the resultant morbidity and mortality.Listeriaspp. are a group of aerobic and non-spore forming gram-positive bacilli. They are present in the environment, soil, and water.Listeriaspp. have also been noted to be present as a normal intestinal flora of animals. They are known for their ability to thrive under both cold and hot environmental conditions. Human infections withListeriaspp. have not been frequently reported, mostly because of the difficulty in laboratory identification and complex clinical presentations. In humans,Listeriaspp. have been frequently responsible for food poisoning and neonatal meningitis. Although not considered as a classic pathogen,Listeriaspp. are associated with infections in elderly people, pregnant women, newborns, and persons with weakened immune systems. This report presents a case of breast abscess caused byListeriaspp. in a young lactating female belonging to rural India.
