Lactobacillus crispatus DSM 20584 = JCM 1185 = ATCC 33820 strain

Lactobacillus crispatus DSM 20584 (also known as JCM 1185 and ATCC 33820) is a Gram-positive, rod-shaped bacterium that is categorized as a facultative anaerobe. This strain is notable for its non-motility, lacking flagella, and typically arranges itself in chains. The optimal growth temperature for L. crispatus is 37°C, indicating its mesophilic nature, which aligns with the typical body temperature of its hosts. This bacterium is primarily host-associated and exhibits a free-living biotic relationship. It has been identified in various hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), Aves (birds), and Olea europaea (olive trees). The presence of L. crispatus in these diverse hosts suggests its ecological versatility and potential roles in different biological systems. L. crispatus is characterized by a single replicon and possesses one membrane. It does not undergo sporulation, which may influence its survival strategies in various environments. The strain is cataloged under the accession number AZCW00000000.1, highlighting its recognized genetic profile. In summary, Lactobacillus crispatus DSM 20584's traits, such as its facultative anaerobic metabolism and association with diverse hosts, underscore its ecological adaptability. Its presence in both animal and plant hosts may reflect its roles in gut health and fermentation processes, contributing to the microbiomes of these organisms.
