| recognition of plasmodium falciparum asexual stage antigens by antibodies in sera from people exposed to plasmodium vivax. | an analysis of plasmodium falciparum antigen-specific antibodies was performed on 44 serum samples from guatemala, a region endemic for p. vivax. most sera showed positive reactivity to p. falciparum asexual stage antigens by indirect immunofluorescent assay, enzyme-linked immunosorbent assay, and immunoprecipitation analysis using biosynthetically labeled parasites. although several antigens were recognized by these sera, proteins with molecular weights of 195 kd, 140 kd, and in the range of 70 ... | 1992 | 1279995 |

| sociocultural factors in the control and prevention of parasitic diseases. | control and prevention of parasitic disease depends on an adequate knowledge of interactions among factors such as human behavior, the environment, and the life cycles of parasites. sociocultural factors in large part determine transmission and persistence of parasites. the main determinants are poverty, low educational level, deficiencies in home technologies, high demographic density, and ruralism. selected interventions designed to improve any of these situations may fail if they are applied ... | 1982 | 6214836 |
| poor response to primaquine in two cases of plasmodium vivax malaria from guatemala. | two cases of relapsing malaria infection by plasmodium vivax from guatemala are presented in patients treated with current standard doses of chloroquine and primaquine. the difficulties in recognizing resistance to chloroquine versus poor response to standard primaquine schedules are discussed. the recent recommendations of adopting a schedule of 6 mg/kg as a total dose of primaquine proved in our cases to be effective in obtaining a radical cure of the infection. | 1994 | 8165734 |
| short report: primaquine-tolerant plasmodium vivax in an italian traveler from guatemala. | plasmodium vivax infections caused by strains with low sensitivity to primaquine are widespread in the western pacific and southeast asia, and have been recently reported from central america as well. we report a case of primaquine failure in a p. vivax infection acquired in guatemala. a 28-year-old italian woman developed two months after returning from guatemala a vivax malaria attack that was treated with a standard chloroquine course (1,500 mg over three days) combined with primaquine (15 mg ... | 1996 | 8940974 |

| in vivo and in vitro antiplasmodial activities of some plants traditionally used in guatemala against malaria. | we present an evaluation of the antiplasmodial and cytotoxic effects of four plants commonly used in guatemalan folk medicine against malaria. methanol extracts of simarouba glauca d. c., sansevieria guineensis willd, croton guatemalensis lotsy, and neurolaena lobata (l.)r.br. significantly reduced parasitemias in plasmodium berghei-infected mice. dichloromethane fractions were screened for their cytotoxicities on artemia salina (brine shrimp) larvae, and 50% inhibitory concentrations were deter ... | 1997 | 9210673 |
| [introduction of bacillus sphaericus strain-2362 (griselesf) for biological control of malaria vectors in guatemala]. | malaria continues to be an important health problem in a number of countries of central and south america where it is considered as a highly prevent endemic disease. the objective of this paper is to assess the entomo-epidemiological impact of a pilot program for the biological control of malaria-transmitting vectors, which was implemented in 1998 in escuintla, republic of guatemala. this program was based on the use of 20,000 l of biolarvicide bacillus sphaericus- strain-2362 (griselesf) which ... | 2000 | 11107892 |
| antiplasmodial activities of sesquiterpene lactones from eupatorium semialatum. | eupatorium semialatum, plasmodium falciparum, sesquiterpene lactones eupatorium semialatum is a member of the asteraceae, which occurs in guatemala. previously, we reported the occurrence of sesquiterpene lactones of the eudesmanolide type as main constituents in the leaves. this paper deals with the isolation and identification of the first guaianolide found in e. semialatum. since this plant is used against malaria and other diseases in the guatemalan folk medicine, the main sesquiterpene lact ... | 2002 | 12064727 |
| fever of unknown origin. | this is a case study of a 26-year-old hispanic male who presented with an initial complaint of fevers, chills and generalized weakness for three weeks. patient reported a classical history of diurnal fever with temperature spikes as high as 105.8f after returning from a trip to guatemala. his symptoms had waxed and waned for 3 weeks. this case study will focus on the initial presentation, value of complete history and physical exam, use of laboratory data and use of specialized diagnostic proced ... | 2003 | 14651378 |
