Salmonella enterica subsp. enterica serovar Enteritidis strain BAA

Salmonella enterica subsp. enterica serovar Enteritidis strain BAA is a Gram-negative, microaerophilic bacterium that primarily inhabits various hosts, including Homo sapiens and several animal species such as Gallus gallus (chickens), Sus scrofa (pigs), and Canis lupus familiaris (domestic dogs). This strain is classified as a chemoorganotroph, utilizing organic compounds for energy. Its cellular structure is characterized by a spirilla shape, and it typically forms chains and singles. S. Enteritidis strain BAA is notable for its pathogenic potential in humans, causing diseases such as salmonellosis, bloodstream infections, diarrhea, and foodborne outbreaks. The bacterium also poses risks to avian species, leading to conditions such as avian salmonellosis and paratyphoid diseases. The optimal growth temperature for this mesophilic organism is 37°C, which coincides with the body temperature of its primary hosts, facilitating its survival and replication in these environments. The strain possesses flagella, suggesting motility, although it is noted for no active movement. With a total of one replicon and two membranes, this bacterium exhibits characteristics typical of many Gram-negative pathogens. Its ability to thrive in host-associated environments signifies its role in complex biological relationships, especially in the context of zoonotic diseases. Understanding the ecological dynamics of S. Enteritidis is imperative, as it underscores the importance of monitoring food safety and public health in relation to this pathogen.
