Age-specific mortality patterns in Central Mozambique during and after the end of the Civil War
(Springer Science and Business Media LLC, 2011-05-26)Background: In recent years, vigorous debate has developed concerning how conflicts contribute to the spread of infectious diseases, and in particular, the role of post-conflict situations in the epidemiology of HIV/AIDS. ... -
AIDS-related knowledge and sexual behaviour among married and previously married persons in rural central Mozambique
(Informa UK Limited, 2009-11)HIV prevalence in central Mozambique is the highest in the country with high urban rates impacting on the rural areas. To identify potential factors influencing the spread of HIV in three sparsely populated districts in ... -
Development of a loop-mediated isothermal amplification (LAMP) assay for rapid screening of ticks and fleas for spotted fever group rickettsia
(Public Library of Science (PLoS), 2018-02-01)Background: The importance of tick and flea-borne rickettsia infections is increasingly recognized worldwide. While increased focus has shifted in recent years to the development of point-of-care diagnostics for various ... -
Exflagellation responses of cultured Plasmodium falciparum (Haemosporida: Plasmodiidae) gametocytes to human sera and midguts of anopheline mosquitoes (Diptera: Culicidae)
(Oxford University Press (OUP), 1994)The process of exflagellation was quantified for cultured Plasmodium falciparum gametocytes exposed to human sera and midgut homogenates from six vector species of Anopheles mosquitoes. Neither serum factors related to ... -
Exogenously scavenged and endogenously synthesized heme are differentially utilized by Mycobacterium tuberculosis
(American Society for Microbiology, 2022-10-26)Heme is both an essential cofactor and an abundant source of nutritional iron for the human pathogen Mycobacterium tuberculosis. While heme is required for M. tuberculosis survival and virulence, it is also potentially ... -
Exposure and risk factors to Coxiella burnetii, spotted fever group and typhus group rickettsiae, and Bartonella henselae among volunteer blood donors in Namibia
(Public Library of Science (PLoS), 2014-09-26)Background: The role of pathogen-mediated febrile illness in sub-Saharan Africa is receiving more attention, especially in Southern Africa where four countries (including Namibia) are actively working to eliminate malaria. ... -
First Documented Pathologies in Tenontosaurus tilletti with Comments on Infection in Non-Avian Dinosaurs
(2019-06-18)In 2001, a nearly complete sub-adult Tenontosaurus tilletti was collected from the Antlers Formation (Aptian-Albian) of southeastern Oklahoma. Beyond its exceptional preservation, computed tomography (CT) and physical ... -
Flea-borne rickettsioses: Ecologic considerations
(Centers for Disease Control and Prevention (CDC), 1997-07)Ecologic and economic factors, as well as changes in human behavior, have resulted in the emergence of new and the reemergence of existing but forgotten infectious diseases during the past 20 years. Flea-borne disease ... -
Immunological factor that affects Anopheles gambiae survival
(The American Mosquito Control Association, 1995)High titers of antibodies against Anopheles gambiae midguts were produced in New Zealand rabbits to identify midgut targets for an antimosquito vaccine. The serum from one of 8 rabbits (designated R2B6) killed 71.6% (Abbott's ... -
Impact of variations in temperature on early Plasmodium falciparum development in Anopheles stephensi
(Cambridge University Press (CUP), 1995) -
Influence of religious affiliation and education on HIV knowledge and HIV-related sexual behaviors among unmarried youth in rural central Mozambique
(Informa UK Limited, 2010-10)The interactions between religious affiliation, education, HIV knowledge, and HIV-related sexual behaviors among African church youth are poorly understood. In this socio-demographic study, 522 unmarried youth 12-28 years ... -
Ingestion of Plasmodium falciparum sporozoites during transmission by anopheline mosquitoes
(American Society of Tropical Medicine and Hygiene, 1992)We investigated the process of sporozoite transmission during blood feeding for Anopheles gambiae and An. stephensi experimentally infected with Plasmodium falciparum. When infective mosquitoes were fed 22-25 days postinfection ... -
Invasive plants as foci of mosquito-borne pathogens: Red cedar in the southern Great Plains of the USA
(Springer Science and Business Media LLC, 2021-10-05)West Nile virus (WNV) is the most significant mosquito-borne disease affecting humans in the United States. Eastern redcedar (ERC) is a native encroaching plant in the southern Great Plains that greatly alters abiotic ... -
Low seroprevalence of antibodies to Toxoplasma gondii in blood donors in central Namibia
(Informa UK Limited, 2014)Although emphasis has been placed on research relating to human immunodeficiency virus (HIV), tuberculosis and malaria, several researchers in Africa are focusing on other threats to human health, such as neglected tropical ... -
Mapping of schistosomiasis and soil-transmitted helminths in Namibia: The first large-scale protocol to formally include rapid diagnostic tests
(Public Library of Science (PLoS), 2015-07-21)Background: Namibia is now ready to begin mass drug administration of praziquantel and albendazole against schistosomiasis and soil-transmitted helminths, respectively. Although historical data identifies areas of transmission ... -
Mosquito ingestion of antibodies against mosquito midgut microbiota improves conversion of ookinetes to oocysts for Plasmodium falciparum, but not P. yoelii
(Elsevier BV, 2011-07-13)The mosquito midgut is a site of complex interactions between the mosquito, the malaria parasite and the resident bacterial flora. In laboratory experiments, we observed significant enhancement of Plasmodium falciparum ... -
Mosquito-borne parasites in the Great Plains: Searching for vectors of nematodes and avian malaria parasites
(Elsevier BV, 2021)Vector-borne diseases in the United States have recently increased as a result of the changing nature of vectors, hosts, reservoirs, parasite/pathogens, and the ecological and environmental conditions. While most focus has ... -
