Salmonella enterica subsp. enterica strain LSP 389/97

Salmonella enterica subsp. enterica strain LSP 389/97 is a gram-negative, microaerophilic bacterium characterized by its spirilla shape and chains or singles cell arrangement. It is a chemoorganotroph, relying on organic compounds for energy. This strain is a free-living organism found in various host-associated habitats, including Homo sapiens (humans), Gallus gallus (domestic chickens), Sus scrofa (pigs), and multiple other metazoan species, including mammals, amphibians, and fish such as Lates niloticus (Nile perch). Strain LSP 389/97 has a mesophilic temperature range, with an optimal growth temperature of 37°C. It possesses a single replicon and has two membranes, which is characteristic of gram-negative bacteria. The strain does not produce spores, indicating it is nonsporulating. Notably, it is motile due to the presence of flagella. In terms of health implications, this strain is associated with several illnesses, including salmonellosis, gastroenteritis, mastitis, and breast abscesses in humans and animals. This highlights its potential impact on public health and veterinary medicine. The ecological insight provided by the host range of S. enterica subsp. enterica strain LSP 389/97 suggests that it plays a significant role in the transmission of pathogens across different species, which can facilitate zoonotic disease outbreaks. Understanding its behavior and interactions within various hosts can inform strategies for managing and preventing salmonellosis in both human and animal populations.
