Molecular Identification of Rickettsia typhi and R. felis in Co-Infected Ctenocephalides felis (Siphonaptera: Pulicidae)

Journal of Medical Entomology, 1998
Rickettsia typhi and R. felis, 2 closely related rickettsial species, often have been identified in cat fleas, Ctenocephalides felis (Bouché) from the same geographical location. However, no fleas have been found to be naturally infected concurrently with both rickettsial species.

Detection of R. felis and R. typhi in Fleas Using Monoclonal Antibodies

Annals of the New York Academy of Sciences, 2003
Abstract: Rickettsia typhi and R. felis are flea‐transmitted human pathogenic rickettsial species. To investigate the distributional dynamics of these rickettsiae we designed a micro‐immunofluorescence assay (MIF) using species‐specific monoclonal antibodies (MAbs) applied to flea cryosections.

Intracellular movements of Rickettsia conorii adn R. typhi based on actin polymerization

Research in Microbiology, 1992
Human vascular endothelial, Vero and human embryonic lung cells infected with rickettsiae for 24 h or 48 h were labelled for polymerized actin with NBD-phallacidin. Between 20 and 68% of the intracellular Rickettsia conorii had an actin tail of between 0.33 and 15 microns, with the longest tails being observed in Vero cells. In the case of R.

A novel broadly applicable PCR-RFLP method for rapid identification and subtyping of H58 Salmonella Typhi [PDF]

Journal of Microbiological Methods, 2016
Salmonella Typhi (S. Typhi), the human-adapted agent of typhoid fever, is genetically monomorphic. SNPs accumulation divided the S. Typhi population in 85 haplotypes (H) of which one, H58, has undergone a clonal expansion.

Escherichia coli R-factors unstable in Salmonella typhi are deleted before being segregated in this host

Plasmid, 2004
Although resistant Salmonella typhi strains are found in the environment, many epidemiological data indicate that most isolates are multisensitive. Plasmids are not common in S. typhi, contrasting with other enterobacteria. Since S. typhi is able to receive R plasmids from other enterobacteria, such plasmidless condition may be due to destabilization ...

Salmonella typhi R-plasmids in Hungary.

Acta microbiologica Academiae Scientiarum Hungaricae, 1981
The antibiotic sensitivity of 4095 Salmonella typhi strains isolated in Hungary from January, 1974 to June 1979, was tested. Twelve strains derived from one patient and seven chronic carriers were resistant to antibiotics due to R-plasmids. One of the S.

Molecular characterization of a conjugative R-lac plasmid in Salmonella typhi isolated from a patient with typhoid fever

Annales de l'Institut Pasteur / Microbiologie, 1987
In a strain of Salmonella typhi isolated from a patient with post-operative typhoid fever, a 217-Kb conjugative plasmid has been detected which codes for lactose fermentation and drug resistance to sulphonamides (SA), chloramphenicol (CP), ampicillin (AP), kanamycin (KM) and trimethoprim (TP). The physical and genetic map was constructed.
