What are the virulence factors of chlamydia?
A number of candidate virulence factors have been identified, including the polymorphic outer membrane autotransporter family of proteins, the putative large cytotoxin, type three secretion effectors, stress response proteins and proteins or other regulatory factors produced by the cryptic plasmid.
What is the pathogenesis of Chlamydia infection?
Disease pathogenesis due to Chlamydia trachomatis is a complicated process that involves: (1) exposure to the organism and infectivity; (2) survival within the host cell; (3) virulence associated with specific strain types; (4) innate and acquired immunity, and (5) host genetic susceptibility to infection and disease.
What is the vector of Chlamydia trachomatis?
coli-Chlamydia shuttle vectors, for C. trachomatis and C. muridarum. These versatile vectors allow for expression and localization studies of Chlamydia effectors, such as Inc proteins, and will be instrumental for mutant complementation studies.
What is chlamydia plasmid?
Carlson JH, et al. The Chlamydia trachomatis plasmid is a transcriptional regulator of chromosomal genes and a virulence factor.
What is the virulence factor of gonorrhea?
pili
gonorrhoeae possesses a wide range of virulence determinants, which include the elaboration of pili, Opa protein expression, lipooligosaccharide expression (LOS), Por protein expression and IgA1 protease production that facilitates adaptation within the host.
Is Chlamydia a bacilli or cocci?
(bacterium) Typical representatives: Staphylococci are the most common cluster-forming cocci. Chlamydia trachomatis is an intracellular, Gram-negative bacterium in the Chlamydiaceae family.
What does Chlamydia trachomatis cause?
Chlamydia is a common STD caused by infection with Chlamydia trachomatis. It can cause cervicitis, urethritis, and proctitis.
Is chlamydia a cocci or bacilli?
Is chlamydia a rod or bacilli?
Pathogen name and classification Chlamydia trachomatis(C. trachomatis)is a Gram-negative coccoid or rod-shaped bacteria that causes genitourinary tract and eye infections.
Does Chlamydia trachomatis have a plasmid?
A 7.4-kb plasmid is a common and perhaps essential component of the Chlamydia trachomatis genome. This plasmid occurs as 10 copies per chlamydial chromosomal equivalent. It is unable to replicate in Escherichia coli. Complete plasmid genomes from eight serovars of C.
What is cryptic plasmid?
Cryptic plasmids are extrachromosomal DNA elements that encode no recognizable phenotype besides their replication functions (von Wright and Sibakov, 1998. 1998. Genetic modification of lactic acid bacteria, In S. Salminen & A. von Wright.
