Francisella tularensis subsp. novicida strain DPG 3A-IS

Francisella tularensis subsp. novicida strain DPG 3A-IS is a Gram-negative, rod-shaped bacterium that exhibits a free-living biotic relationship and inhabits aquatic environments. This strain is classified as an aerobe, meaning it requires oxygen for growth, and it is mesophilic, thriving within moderate temperature ranges. The cell arrangement of strain DPG 3A-IS is characterized by singles, indicating that the bacterial cells do not typically form clusters or chains. Notably, this strain lacks mobility, despite possessing flagella, which suggests that the flagella may not be functional for motility in this context. Genetically, strain DPG 3A-IS contains two replicons and has a double-membrane structure, a characteristic feature of many Gram-negative bacteria. Its health implications are significant, as it is associated with tularemia, a disease that can affect both humans and animals. The understanding of F. tularensis subsp. novicida strain DPG 3A-IS emphasizes its ecological role in aquatic habitats and highlights its potential impact on health through the transmission of tularemia. Its free-living nature allows it to interact with various environmental factors, which may influence its pathogenicity and survival strategies in natural ecosystems. The data underscore the importance of monitoring this bacterium in aquatic environments to assess risks to public health.
