Pathogenic Leptospira species cause a prevalent yet neglected zoonotic disease with mild to life-threatening complications in a variety of susceptible animals and humans. Diagnosis of leptospirosis, which primarily relies on antiquated serotyping methods, is particularly challenging due to presentation of non-specific symptoms shared by other febrile illnesses, often leading to misdiagnosis. In...

Leptospirosis, a major health problem worldwide, is known to be endemic in the northeastern part of Thailand with the risk of infection by exposure to pathogenic Leptospira in contaminated aquatic environment. A method based on PCR-hybridization detection of pathogenic Leptospira in water was established. The method included filtration of water sample through membrane filters of two pore sizes,...

Leptospirosis is a spirochetal zoonotic disease of global distribution with a high incidence in tropical regions. In the last 15 years it has been recognized as an important emerging infectious disease due to the occurrence of large outbreaks in warm-climate countries and, occasionally, in temperate regions. Pathogenic leptospires efficiently colonize target organs after penetrating the host. T...

Leptospirosis is a zoonotic disease with global distribution that caused by pathogenic spirochetes of the genus Leptospira. Accurate diagnosis for differentiation of leptospirosis from other pyrogenic infections prevailing in the same locality and is imperative for proper treatment. Therefore a molecular diagnostic test with high specificity and sensitivity such as PCR is essential. Gene encodi...

BACKGROUND Leptospirosis, one of the most widespread zoonotic infectious diseases worldwide, is caused by spirochetes bacteria of the genus Leptospira. The present study examined inhibitory activity of purified xanthones and crude extracts from Garcinia mangostana against both non-pathogenic and pathogenic leptospira. Synergy between γ-mangostin and penicillin G against leptospires was also det...

A macroscopic agglutination test for detecting leptospiral antibodies in human sera is described. The test utilizes a stained preparation of non-pathogenic leptospires and is performed on the Brewer diagnostic cards used for bovine brucellosis screening. The agglutination of the stained antigen is more easily observed than the current macroscopic slide test using unstained leptospiral antigens....

Five leptospiral strains were isolated from bovine kidneys during a cultural survey for pathogenic leptospires in Nigeria. Preliminary test results indicated that the five strains were identical and serologically heterologous to the other members of the Pyrogenes serogroup. Further examination of the strains by the cross-agglutinin absorption test, factor analysis and restriction endonuclease a...

Major progress has been made in the basic research of leptospirosis a global zoonotic disease. Recent knowledge on the genome of L. interrogans and the emergence of new genetic tools for comparative genetic studies have further developed research into the genetic pathogenesis of this illness. Many of these studies have compared the putative pathogenicity factors found in L. interrogans, with re...

Background In tropical areas, Leptospirosis is still considered a public health problem, particularly in the event of heavy rainfall and flooding. Transmission leptospira bacteria from infected animals, such as rats, takes place through urine or blood. Different serovar leptospires can be found different reservoir animals field. However, research on presence pathogenic rats Pati Regency, one ar...

Leptospirosis is a widespread zoonosis, potentially severe in humans, caused by spirochetal bacteria, Leptospira interrogans (L. interrogans). Host defense mechanisms involved in leptospirosis are poorly understood. Recognition of lipopolysaccharide (LPS) and lipoproteins by Toll-Like Receptors (TLR)4 and TLR2 is crucial for clearance of leptospires in mice, yet the role of Nucleotide Oligomeri...
