Typhoid fever is a bacterial infection caused by the Gram-negative bacterium Salmonella enterica subspecies serovar Typhi (S. Typhi), prevalent in many low- and middle-income countries. In high-income territories, typhoid predominantly travel-related, consequent to travel typhoid-endemic regions; however, data show that level of vaccination travellers low. Successful management using antibiotic...
b a ckground: zoonotic cutaneous leishmaniasis (zcl) is endemic in many parts of iran. recently its incidence isconsiderable in different parts of jahrom district, in fars province, southern iran. the aims of our study were to in- vestigate the prevalence of leishmania infection, and identify and characterize the leishmania species present, among the rodents by molecular methods in a new ende...
More than 50 countries have eliminated malaria, but increasing travel to malaria-endemic countries ensures that imported cases of malaria remain common in non-endemic countries. Patterns of imported malaria vary by country and reflect several factors, notably the intensity of transmission in the endemic country and the number and behavior of people visiting that country. Most information on imp...
The correlation between the geographic occurrence of Balkan endemic nephropathy (BEN) and low rank Pliocene lignites is striking. Comparison of mass spectra of methanol extracts from lignite samples collected in the vicinity of two endemic villages, with mass spectra of methanol extracts higher grade coals, shows the presence of many more potentially nephrotoxic compounds, and much higher total...
Phylogenetic evidence suggests that endemic and epidemic dengue viruses (DENV), transmitted among humans by the anthropophilic mosquitoes Aedes aegypti and Ae. albopictus, emerged when ancestral, sylvatic DENV transmitted among nonhuman primates by sylvatic Aedes mosquitoes adapted to these peridomestic vectors. We tested this hypothesis by retrospectively examining evidence for adaptation of e...
Blastomycosis, a fungal infection caused by Blastomyces dermatitidis, was once thought to be endemic only to the Central and Great Lakes regions of the United States of America. We present the first reported case series of patients documenting the diagnosis of blastomycosis in the Pacific region. In both cases, exposure to endemic areas was retrospectively identified. ness of symptoms during cl...
BACKGROUND Strains of the Beijing genotype of Mycobacterium tuberculosis (MTB) are reportedly associated with the virulence of tuberculosis (TB) infection, unfavorable outcomes of anti-TB treatment, and the global TB pandemic. Rv0679c, a hypothetical membrane protein related to host cell invasion, has a Beijing genotype-specific mutation at residue 142 (Asn142Lys). Antigenicity differences betw...
