Microbe Identification
Microbe namePeptoniphilus lacrimalis
NCBI Taxonomy ID33031
DescriptionPeptoniphilus lacrimalis is a Gram-positive, spherical-shaped microbe that thrives in temperatures between 25-37°C, categorizing it as a mesophilic organism. It is a chemoheterotroph, meaning it derives its energy by breaking down organic compounds and using them as its energy source. P. lacrimalis produces energy through the process of fermentation, converting glucose and other carbohydrates into lactic acid and other byproducts. This microbe is found in various body sites, including the nasal cavity, oral cavity, and eyes of humans and animals, as well as in soil and water. Its ability to thrive in these diverse environments makes it a ubiquitous member of the microbial community. P. lacrimalis is an anaerobe, meaning it requires a low-oxygen environment to survive. In fact, it is an obligate anaerobe, unable to tolerate the presence of oxygen and will not grow in its presence. This adaptation allows it to thrive in environments where oxygen is limited, such as deep within the eye or in the nasal cavity. In addition to its unique physiological characteristics, P. lacrimalis has also been found to be resistant to antimicrobial peptides, making it a challenging microbe to treat in cases of infection. Its ability to adhere to host cells and evade the immune system also contributes to its pathogenic potential. P. lacrimalis has been shown to play a role in a range of diseases, including conjunctivitis, sinusitis, and peritonitis. Further research into its biology and pathogenesis has the potential to inform the development of novel therapeutic strategies for treating these conditions.
