Since 1960, a total of seven species of monkey malaria have been reported as transmissible to man by mosquito bite: Plasmodium cynomolgi, Plasmodium brasilianum, Plasmodium eylesi, Plasmodium knowlesi, Plasmodium inui, Plasmodium schwetzi and Plasmodium simium. With the exception of P. knowlesi, none of the other species has been found to infect humans in(More)
Previously, Plasmodium knowlesi was not considered as a species of Plasmodium that could cause malaria in human beings, as it is parasite of long-tailed (Macaca fascicularis) and pig-tailed (Macaca nemestrina) macaques found in Southeast Asia. A case of infection by P. knowlesi is described in a Spanish traveller, who came back to Spain with daily fever(More)
We present filaria-nested polymerase chain reaction (PCR), which is based on amplification of first internal transcribed spacer rDNA to distinguish three parasitic filarial species (Onchocerca volvulus, Mansonella ozzardi and Mansonella perstans) that can be found in the Amazon Region. Nested PCR-based identifications yielded the same results as those(More)
Cryptosporidium spp. and microsporidia are opportunistic parasites affecting a wide range of hosts in which they can be potentially life threatening in immunocompromised individuals. Diagnosis usually relies on the identification of the stained Cryptosporidium oocyst or microsporidial spores, but these methods lack sensitivity and require highly trained(More)
In this work, two well-known classical PSO schemes have been modified by introducing a tournament selection strategy, commonly used in genetic algorithms, and the new hybrid PSO schemes (HPSO) have been applied to planar array synthesis. The classical PSO schemes with either synchronous or asynchronous updates of the swarm and a global topology are(More)
Mansonellosis is endemic in several regions of Africa, the Caribbean, and Latin America. Mansonella ozzardi and Mansonella perstans have been reported in Latin America, including the Amazon region. A morphological and molecular microfilariae study was performed in Pauini (Brazil). Blood samples were collected from 40 individuals, and were analyzed by(More)
Malaria is a vectorborne disease caused by protozoan of the genus Plasmodium, which can also be transmitted by the transfusion of infected red blood cells. One year after return from a travel to Honduras, a Spanish traveller developed vivax malaria. Prior to the onset of symptoms, the donor made a donation that tested non-reactive using an immunological(More)
OBJECTIVE To develop a new technique for diagnosis of Plasmodium knowlesi and at the same time to be able to discriminate among the diverse species of Plasmodium causing human malaria. METHODS In this study the nested multiplex malaria PCR was redesigned, targeting the 18S rRNA gene, to identify the fifth human Plasmodium species, Plasmodium knowlesi,(More)
