Porphyromonas gingivalis FimA and Mfa1 fimbriae: Current insights on localization, function, biogenesis, and genotype

Japanese Dental Science Review, 2021
In general, the periodontal pathogen Porphyromonas gingivalis expresses distinct FimA and Mfa1 fimbriae. Each of these consists of five FimA–E and five Mfa1–5 proteins encoded by the fim and mfa gene clusters, respectively.

Investigation of periodontal disease development and Porphyromonas gulae FimA genotype distribution in small dogs

Scientific Reports
In dogs, Porphyromonas gulae is a major periodontal pathogen with 41-kDa proteins polymerizing to form a filamentous structure called fimbriae or pili, termed FimA. FimA is classified into three genotypes: A, B, and C, and there are combinations of types

Type I fimbriae subunit fimA enhances Escherichia coli biofilm formation but affects L-threonine carbon distribution

Frontiers in Bioengineering and Biotechnology, 2022
The biofilm (BF) provides favorable growth conditions to cells, which has been exploited in the field of industrial biotechnology. Based on our previous research works on type I fimbriae for the biosynthesis of L-threonine (LT) in Escherichia coli, in ...

Distribution of Porphyromonas gingivalis fimA and mfa1 fimbrial genotypes in subgingival plaques [PDF]

PeerJ, 2018
Background Strains of periodontal disease-associated bacterium Porphyromonas gingivalis have different pathogenicity, which can be attributed to clonal genetic diversity. P.

Efficacy of FimA antibody and clindamycin in silkworm larvae stimulated with Porphyromonas gulae

Journal of Oral Microbiology, 2021
Objective: Porphyromonas gulae, a major periodontal pathogen in animals, possesses fimbriae that have been classified into three genotypes (A, B, C) based on the diversity of fimA genes encoding fimbrillin protein (FimA). P.

Frequency of Porphyromonas gingivalis fimA in smokers and nonsmokers after periodontal therapy

Journal of Applied Oral Science, 2019
Porphyromonas gingivalis is one of the most important Gram-negative anaerobe bacteria involved in the pathogenesis of periodontitis. P. gingivalis has an arsenal of specialized virulence factors that contribute to its pathogenicity.

The gut microbiota induces melanin deposits that act as substrates for fimA-mediated aggregation of Salmonella Typhimurium and enhance infection of the German cockroach vector

Microbiology spectrum, 2023
When Salmonella Typhimurium is ingested by German cockroaches, the bacteria replicate in the gut and persist for at least 7 d, enabling transmission in the feces.

Passive immunization with anti-FimA egg yolk antibodies (IgYs) mitigate Acinetobacter baumannii pneumonia in mice.

Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2023
Acinetobacter baumannii is a formidable pathogen, characterized by high mortality rates and pan-drug-resistant strains. Current commercial antibiotics lack efficacy against drug-resistant variants, necessitating the search for alternative treatments ...
