Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...

Ureaplasma urealyticum has been divided into 14 serovars. Recently, subdivision of U. urealyticum into two species has been proposed: U. parvum (previously U. urealyticum parvo biovar), comprising four serovars (1, 3, 6, 14) and U. urealyticum (previously U. urealyticum T-960 biovar), 10 serovars (2, 4, 5, 7-13). The multiple-banded antigen (MBA) genes of these species contain both species and ...

Reference strains of the Mycobacterium avium complex (MAC) belonging to serovars 1 to 28 were examined with DNA probes (Gen Probe Rapid Diagnostic System for the MAC; Gen Probe Inc., San Diego, Calif.) specific for either M. avium or Mycobacterium intracellulare. This study revealed that the earlier designations of the MAC serovars, in which serovars 1 to 3 and 4 to 28 were regarded as M. avium...

background leptospirosis is recognized as a re-emerging infectious disease; therefore, understanding the epidemiology of the disease is vital for designing intervention programs and diminishing its transmission. recently, multilocus variable number tandem repeat analysis (mlva) is used for segregating and identifying leptospira serovars. the method has potential application in investigating the...

A total of 66 serovars of potentially pathogenic Leptospira species were examined by slot blot hybridization, and 57 of these serovars were classified in six DNA homology groups. In cases in which common serovars were studied, the results were in general agreement with the results of previous workers, who used different DNA homology methods. However, we propose a new species, Leptospira kirschn...

Leptospirosis caused by infection with pathogenic leptospires, which is the most prevalent zoonotic disease in the world. The outer membrane proteins (OMPs) of pathogenic leptospires such as LipL41 play a crucial role in pathogenesis of this disease. Therefore a major challenge to develop an effective vaccine against leptospirosis is application of basic research on the OMPs of leptospires to i...

Background and Aims: Leptospirosis is a spirochetal disease with public health importance globally. This disease affects a wide range of domestic and wild animals. Dogs are one of the species most sensitive to Leptospira canicola and Leptospira icterohaemorrhagiae. The present study was concluded to evaluate the prevalence rate of Leptospira species and L. canicola and L. icterohaemorrhagiae se...

L eptospirosis is a worldwide zoonotic disease caused by infection with the spirochete bacterium Leptospira inteTragons.L. interrogans is further divided on the basis of antigenic relatedness into serogroupsand serovars. Approximately 200 different serovars of L. interrogans have been identified, and within a geographic region, certain serovars are prevalent and becomeadapted to a particular ma...
