  • HIV Type 1 gag genetic diversity among antenatal clinic attendees in North Rift Valley, Kenya 
    Ng'ang'a, Zipporah W.; Nyagaka, Benuel; Kiptoo, Michael K.; Lihana, Raphael W.; Khamadi, Samoel A.; Makokha, Ernest P.; Kinyua, Joyceline G.; Mwangi, Joseph; Osman, Saida; Lagat, Nancy J.; Muriuki, Joseph; Okoth, Vincent; Gicheru, Michael; Songok, Elijah M. (Mary Ann Liebert, Inc., 2012)
    HIV genetic recombination and high mutation rate increase diversity allowing it to escape from host immune response or antiretroviral drugs. This diversity has enabled specific viral subtypes to be predominant in specific ...
  • Indirect immunofluorescence assay, particle agglutination and ELISA for the detection of HIV type 1 
    Ng'ang'a, Zipporah W.; Kiptoo, Michael K.; Mpoke, Solomon S.; Osman, Saida; Mwangi, Ann; Songok, Elijah M. (IJIB, 2009)
    Screening of blood and blood products for human immunodeficiency virus (HIV) is routinely performed using the enzyme-linked immunosorbent assay (ELISA), and the results confirmed by western blot (WB). In an effort to ...
  • Molecular genetic diversity of hepatitis B virus in Kenya 
    Ng'ang'a, Zipporah W.; Mwangi, Joseph; Songok, Elijah; Kinyua, Joyceline; Lagat, Nancy; Muriuki, Joseph; Lihana, Raphael; Khamadi, Samoel; Osman, Saida; Lwembe, Raphael; Kiptoo, Michael K.; Mwau, Matilu; Chirchir, Ruth; Mpoke, Solomon; Nyamongo, Jack; Okoth, Fred; Yamada, Rika; Kageyama, Seiji; Ichimura, Hiroshi (S. Karger AG, Basel, 2008)
    Eight genotypes of hepatitis B virus (A-H) and subgenotypes have been recognized worldwide. However, there is limited information on prevalent genotypes in many countries in Africa. This study was undertaken to determine ...
  • Predisposing factors for HIV infection among injecting drug users in Malindi Sub-County, Kenya 
    Ng’ong’a, Gabriel O.; Hunja, Carol W.; Osman, Saida; Lwembe, Raphael M. (2016-01)
    Injecting drug use (IDU) offers a100% chance to transmit blood borne infections. There exist scanty reports on factors predisposing IDUs to HIV infection and spread in Malindi Sub-county. IDUs are a potential bridging ...
  • Prevalence, awareness and risk factors associated with Hepatitis B infection among pregnant women attending the antenatal clinic at Mbagathi District Hospital in Nairobi, Kenya 
    Ngaira, Jacqueline A.; Kimotho, James; Mirigi, Isaac; Osman, Saida; Ng'ang'a, Zipporah W.; Lwembe, Raphael; Ochwoto, Missiani (African Field Epidemiology Network, 2016-08-17)
    Introduction Hepatitis B Viral Infection (HBV) remains one of the leading cause of morbidity and mortality globally accounting for 38-53% of chronic liver diseases and about 686,000 deaths annually. The prevalence of HBV ...
