Unique Identifier : AIDSLINE ASHM5/94348955 AB Although microsporidia (MS) are important opportunistic pathogens in Acquired Immunodeficiency Syndrome (AIDS) patients, the in vitro characteristics and seroprevalence of many human species are poorly understood. Light microscopy and electron microscopy confirmed the presence of Encephalitozoon sp spores from a nasopharyngeal aspirate (NPA), urine and faeces from an AIDS patient. MS from NPA inoculated into Human Embryonic Lung cells and macrophages were found to replicate successfully. Seroprevalence studies indicated a high incidence of antibody to the parasite in both Human Immunodeficiency Virus (HIV) positive and HIV negative groups.
