Introduction Highly pathogenic avian influenza (HPAI) is a markedly contagious viral disease of domestic chickens and turkeys, characterized by severe illness with high morbidity and mortality (Easterday et al. 1997). Human infections with the HPAI virus H5N1 frequently cause death since 1997 (Class et al., 1998, Subbarao et al., 1998). Two surface glycoproteins, the haemagglutinin (HA) and neu...
BACKGROUND Human infection with avian influenza H5N1 is an emerging infectious disease characterised by respiratory symptoms and a high fatality rate. Previous studies have shown that the human infection with avian influenza H5N1 could also target organs apart from the lungs. METHODS We studied post-mortem tissues of two adults (one man and one pregnant woman) infected with H5N1 influenza vir...
Listeria monocytogenes is a foodborne pathogen causing listeriosis, especially in sensitive individuals such as children, pregnant women and persons with compromised immune systems. This pathogen has been isolated from different food products, but milk products surely play a major role in the epidemiology of this foodborne disease. identification traditionally involved culture methods based on ...
Malaria is a serious public health problem worldwide. Globally concerted efforts are underway to control and eliminate it. Despite recent slowdown, substantial achievements have been recorded in the last 20 years. However, its eradication requires successful elimination of all Plasmodium parasites among symptomatic, asymptomatic, sub-microscopic infections. This review aimed at assessing...
Currently available human immunodeficiency virus type 1 (HIV-1) RNA quantification assays can detect most viruses of the group M subtypes, but a substantial number are missed or not quantified reliably. Viruses of HIV-1 group O cannot be detected by any commercially available assay. We developed and evaluated a quantitative assay based on nucleic acid sequence-based amplification (NASBA) techno...
Accurate quantification of multidrug resistance-1 gene (MDR1) expression in target cells would be of important therapeutic value in predicting cellular response to anticancer drugs. Because certain normal cells in peripheral blood physiologically express MDR1, increasing the sensitivity of the detection methods might result in confounding low-degree expression in tumor cells with physiologic ex...
