Primers were based on the 28S ribosomal subunit gene. The reaction conditions were optimized and SYTO-82 fluorescent dye was used to allow real-time and visual detection of the product. The product identity was confirmed with restriction enzyme digestion, cloning, and sequence analysis. The assay was specific when tested against DNA from bacteria, fungi and parasites, and 30 normal stool samples. Analytical sensitivity was to < 10 copies of target sequence in a plasmid and up to a 10(-2) dilution of DNA extracted from a Strongyloides ratti larva spiked into stool. Sensitivity was increased when further dilutions were made in water, indicative of reduced reaction inhibition. Twenty-seven of 28 stool samples microscopy and polymerase chain reaction positive for S. stercoralis were positive with the LAMP method. On the basis of these findings, the assay warrants further clinical validation.

Strongyloides cebus (Nematoda: Strongyloididae) in Lagothrix cana (Primates: Atelidae) from the Brazilian Amazon: aspects of clinical presentation, anatomopathology, treatment, and parasitic biology.

Mati VL1, Ferreira Junior FC, Pinto HA, de Melo AL.Author information 1Departamento de Parasitologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, CP 486, CEP 30123-970, Belo Horizonte, MG, Brazil.AbstractAbstract : Seven cases of parasitism by Strongyloides cebus were identified in Lagothrix cana from Brazil. Aspects of the clinical presentation, treatment, pathology, and parasitic biology of these infections are described. Moderate to severe disease was observed, requiring hospitalization of 3 primates, and diarrhea was the most common clinical sign described. One L. cana individual died, for which ulcerative enteritis was the major finding upon histopathological analysis. The use of ivermectin in these atelids was safe and effective against the parasite. Parallel attempts to experimentally infect gerbils with the parasite failed. Lagothrix cana is presented as a new host for S. cebus. The evidence that Strongyloides infections are common in nonhuman primates under free-living conditions, and even more prevalent in captive animals, likely represents a neglected problem.
