We investigated infection of rodents and shrews by Leptospira spp. in two localities of Cambodia (Veal Renh, Kaev Seima) and in four types of habitat (forests, non-flooded lands, lowland rain-fed paddy fields, houses) during the wet and the dry seasons. Habitat preference was common, and rodent and shrew species were found only in houses or in rain-fed paddy fields or in forests. Among 649 smal...
Leptospirosis is an important zoonosis of worldwide distribution. Humans become infected via exposure to pathogenic Leptospira spp. from infected animals or contaminated water or soil. The availability of genome sequences for Leptospira interrogans, serovars Lai and Copenhageni, has opened up opportunities to examine global transcription profiles using microarray technology. Temperature is a ke...
Pathogenic Leptospira spp. are the etiological agents of leptospirosis, an important disease of both humans and animals. In urban settings, L. interrogans serovars are the predominant cause of disease in humans. The purpose of this study was to characterize a novel Leptospira isolate recovered from an abandoned swimming pool. Molecular characterization through sequencing of the rpoB gene reveal...
Leptospirosis, a zoonotic infection with worldwide prevalence, is caused by pathogenic spirochaetes of Leptospira spp., and exhibits an extremely broad clinical spectrum in human patients. Although previous studies indicated that specific serovars or genotypes of Leptospira spp. were associated with severe leptospirosis or its outbreak, the mechanism underlying the difference in virulence of th...
Background: Leptospirosis is an emerging infectious disease and is considered to be the most widespread zoonotic disease in the world. LigB is an immunogenic outer membrane protein. The leptospiral ligB gene expressed only in pathogenic Leptospira spp. The aim of this study was molecular diagnosis of pathogen Leptospires by PCR based on ligB gene. Materials and Methods: Five pathogenic Leptospi...
Leptospirosis is a globally distributed zoonotic disease caused by pathogenic bacteria of the genus Leptospira. This affects humans, domestic animals and wild animals. Colombia considered an endemic country for leptospirosis; Antioquia second department in Colombia, with highest number reported leptospirosis cases. Currently, many studies report bats as reservoirs Leptospira spp. but prevalence...
Leptospirosis has been one of the worldwide zoonotic diseases caused by pathogenic Leptospira spp. Many molecular techniques have consecutively been developed to detect such pathogen including loop-mediated isothermal amplification method (LAMP). The objectives of this study were to evaluate the diagnostic accuracy of LAMP assay and real-time PCR using bacterial culture as the gold standard and...
BACKGROUND Dengue is a leading cause of morbidity throughout the tropics; however, accurate population-based estimates of mortality rates are not available. METHODS/PRINCIPAL FINDINGS We established the Enhanced Fatal Acute Febrile Illness Surveillance System (EFASS) to estimate dengue mortality rates in Puerto Rico. Healthcare professionals submitted serum and tissue specimens from patients ...
