Associations between parasite loads and sexual signal expression have long been the focus of research. However, our understanding how selection operates in context multiple infections within same host is still quite limited. We examined plumage coloration, which sexually selected North American barn swallows, Hirundo rustica erythrogaster, tail streamer length, other swallow subspecies, eight d...

BACKGROUND Helminth infection and malaria remain major causes of ill-health in the tropics and subtropics. There are several shared risk factors (e.g., poverty), and hence, helminth infection and malaria overlap geographically and temporally. However, the extent and consequences of helminth-Plasmodium co-infection at different spatial scales are poorly understood. METHODOLOGY This study was c...

Malaria remains one of the major killers of humankind and persists to threaten the lives of more than one-third of the world's population. Given that human malaria can now be caused by five species of Plasmodium, i.e., Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale, and the recently included Plasmodium knowlesi, there is a critical need not only to augment global...

Infectious diseases threaten the health and survival of wildlife populations. Consequently, relationships between host diversity, host abundance, and parasite infection are important aspects of disease ecology and conservation research. Here, we report on the prevalence patterns of avian Plasmodium and Haemoproteus infections and host relative abundance influence based on sampling 728 wild-caug...

Eighteen hybridoma cell lines were used to study species-specific, stage-specific, and serological cross-reactive antigens of the rodent malarial parasite, Plasmodium yoelii. Specificity and location of plasmodial antigens were determined by indirect fluorescent-antibody analysis. Results showed that a minimum of 12 distinct plasmodial antigens could be distinguished by the 18 hybridomas. Antig...

OBJECTIVE To survey malaria prevalence in Sarbaz from April 2009 to October 2010. METHODS Epidemiological data of 1 464 confirmed malarial patients were analyzed according to demographic status, sex, age, nationality, isolated species and residence place. RESULTS The majority of patients were male 950 (64.8%) but 514 (35.2%) were female. 82.5% of patients were Iranian, 14% Pakistani immigra...

INTRODUCTION Acalculous cholecystitis has been shown to occur in the context of malarial infection with Plasmodium vivax and Plasmodium falciparum and requires prompt diagnosis and treatment to prevent complications. To the best of our knowledge this is the first reported case of the disease occurring in a patient infected with Plasmodium malariae. CASE PRESENTATION We report the first case o...

background: this study investigated the association between pfcrt, t76 allele and chloroquine resistance in patients with falciparum malaria. molecular assays for point mutations on drugs resistance-related genes are applied tools for monitoring emerging resistance and surveillance malaria control strategies in endemic areas. the mutant genotype at codon 76 of plasmodium falciparum chloroquine ...
