Lassa virus (LASV) causes a deadly haemorrhagic fever in humans, killing several thousand people in West Africa annually. For 40 years, the Natal multimammate rat, Mastomys natalensis, has been assumed to be the sole host of LASV. We found evidence that LASV is also hosted by other rodent species: the African wood mouse Hylomyscus pamfi in Nigeria, and the Guinea multimammate mouse Mastomys ery...
Apicoplast, a nonphotosynthetic plastid derived from secondary symbiotic origin, is essential for the survival of malaria parasites of the genus Plasmodium. Elucidation of the evolution of the apicoplast genome in Plasmodium species is important to better understand the functions of the organelle. However, the complete apicoplast genome is available for only the most virulent human malaria para...
Hantaviruses are a diverse group of infectious agents which zoonotic in nature and transmitted to humans through rodent reservoir. enveloped RNA viruses that persistently infect hosts without ill-effect. The host excretes virus urine saliva. Man becomes infected from the rodents when one enters ecological niche other. can cause two types diseases humans: hemorrhagic fever with renal syndrome (H...
In Mizoram (Northeast India), rodent outbreaks are known to occur periodically with the onset of bamboo flowering causing a tremendous destruction to food grains and as per the folk belief, often resulting in famine. In an exploratory survey of rodent pests in bamboo growing atreas for their helminth parasite spectrum, metacestodes of tapeworms were frequently encountered infecting the liver lo...
Many variant proteins encoded by Plasmodium-specific multigene families are exported into red blood cells (RBC). P. falciparum-specific variant proteins encoded by the var, stevor and rifin multigene families are exported onto the surface of infected red blood cells (iRBC) and mediate interactions between iRBC and host cells resulting in tissue sequestration and rosetting. However, the precise ...
Given that rodents are responsible for nearly 280 million cases of undernutrition worldwide and about 400 people affected by rodent-associated zoonoses annually, management rodent populations agricultural pests and/or reservoirs pathogens is a major food security public health matter. In sub-Saharan Africa, the median crop loss due to 16% in field around 8% during storage. The impact on not wel...
Long-term control of triatomine bugs in Chagas endemic regions will depend on a full understanding of vector-parasite-host interactions. Herein we describe a cytochrome b multiplex polymerase chain reaction (PCR)-based strategy for blood meal source identification in bug foregut contents. This technique discriminates human from animal blood, and has been tested in five Triatoma species from Méx...
The 1993 outbreak of hantavirus pulmonary syndrome (HPS) in the southwestern United States was associated with Sin Nombre virus, a rodent-borne hantavirus; The virus' primary reservoir is the deer mouse (Peromyscus maniculatus). Hantavirus-infected rodents were identified in various regions of North America. An extensive nucleotide sequence database of an 139 bp fragment amplified from virus M ...
A total of 719 wild rats were captured from four localities representing the west (Kuala Lumpur), east (Kuantan), north (Georgetown) and south (Malacca) to determine the diversity of blood protozoan from the urban wild rat population in peninsular Malaysia. Five rat species were recovered with Rattus rattus diardii being the most dominant species, followed by Rattus norvegicus, Rattus exulans, ...
Rabies virus presents a global public health problem. Our current understanding of the molecular determinants of rabies virulence stems from rodent models and laboratory strains of the virus, however, it is unclear how well rodent models represent viral response in natural reservoirs. Here, we examined interactions between the raccoon variant of rabies virus (RRV) and its natural host, raccoons...
