OBJECTIVES To estimate the prevalence of active trachoma (TF) in children aged one to nine years and potentially blinding trachoma (TT) in adults aged 15 years and older in six known trachoma-endemic districts in Kenya. DESIGN Community based survey. SETTING Six known trachoma endemic districts in Kenya (Samburu, Narok, West Pokot, Kajiado Baringo and Meru North). SUBJECTS A total of 6,98...
Because both Babesia microti and Borrelia burgdorferi can be transmitted by the bite of a single coinfected Ixodes scapularis tick, an attempt was made to determine frequency with which whole blood samples that tested positive for B. infection polymerase chain reaction (PCR) would also test PCR infection. Over 7-year period from 2013 2019, 119 different patients on at least one sample. Among 11...
•A recent review of small-eared shrews, genus Cryptotis (Mammalia: Insectivora: Soricidae), in the collection of the Museo Nacional de Costa Rica, revealed a previously unidentified specimen of Cryptotis merriami Choate from the Monteverde Cloud Forest Reserve. This specimen is only the second record of C. merriami from Costa Rica, it represents the southernmost record for the species, and it d...
The endemic Australian genus Neodialineura Mann is revised to include 13 species. Three species are previously described: N. nitens (White) and N. saxatilis (White) from southern mainland Australia and Tasmania, and N. striatithorax Mann from eastern Australia. Ten species are described as new, including N. ataxia sp. nov., N. atmis sp. nov., N. bagdad sp. nov, N. bifaria sp. nov., N. litura sp...
BACKGROUND It is unclear how often patients with pneumonia are assessed for Legionella in endemic areas. Additionally, the sensitivity of the IDSA/ATS criteria for recommended Legionella testing is undefined. METHODS We performed a single-center, retrospective study of patients diagnosed with Legionella pneumonia at our hospital to determine: 1) how often Legionella diagnostic testing is obta...
The genus Macromia is represented in Sri Lanka by two endemic species. In this paper a third presumed species described based on single male specimen collected at Kirikitta, Weliweriya, Western Province the low country wet zone of country. weerakooni sp. nov. differs from its congeners having turquoise blue eyes, an entirely black labrum, short yellow ante-humeral stripe, interrupted stripe ant...
Blood transfusion is the second most common transmission route of Chagas disease in many Latin American countries. In Mexico, the prevalence of Chagas disease and impact of transfusion of Trypanosoma cruzi-contaminated blood is not clear. We determined the seropositivity to T. cruzi in a representative random sample, of 2,140 blood donors (1,423 men and 647 women, aged 19-65 years), from a non-...
background : lung cancer is still the leading cause of cancer- related deaths and most of themâ are normally diagnosed in late stages, so there is an urgent need to establish reliable tools for the identification at early stages of the disease. in this study, we use an eleven gene signature test to examine lung biopsy specimens for diagnostic, prognostic & therapeutic purposes. methods : bronc...
BACKGROUND Trachoma is the leading infectious cause of blindness and is caused by ocular infection with the bacterium Chlamydia trachomatis (Ct). While the majority of the global disease burden is found in sub-Saharan Africa, the Western Pacific Region has been identified as trachoma endemic. Population surveys carried out throughout Fiji have shown an abundance of both clinically active tracho...
A putative driver of global amphibian decline is the panzootic chytrid fungus Batrachochytrium dendrobatidis (Bd). While Bd has been documented across continental Africa, its distribution in West Africa remains ambiguous. We tested 793 West African amphibians (one caecilian and 61 anuran species) for the presence of Bd. The samples originated from seven West African countries - Bénin, Burkina F...
