Molecular cloning of components of protective antigenic preparations have suggested that related parasite fatty acid binding proteins could form the basis of the well documented protective, immune cross reactivity between the parasitic trematode worms Fasciola hepatica and Schistosoma mansoni. We have now confirmed the cross protective potential of parasite fatty acid binding proteins and suggest that it may be possible to produce a single vaccine that would be effective against at least two parasites, F. hepatica and S. mansoni of veterinary and human importance respectively.
We found that asthma represents a significant public health problem in this city. Local strategies are urgently needed in order to increase in the availability of prophylactic treatment.
Resumo: Ácaros da família Cheyletidae são de grande importância na veterinária, por estarem associados com parasitismo em aves e mamíferos. Permanecem, contudo, pouco estudados como fatores etiológicos em dermatites humanas, apesar de serem encontradas referências a esse respeito desde o iní-cio do século 20. O objetivo dos autores foi o de analisar, em paciente de seis meses de idade, um caso clínico de dermatite por ácaros da família Cheyletidae. O achado de três espécies dessa família no ecossistema domiciliar desse paciente, associado às manifestações cutâneas e cura definitiva após higienização do ambiente, faz acreditar na necessidade de se considerar essa hipótese diagnóstica nas dermatites humanas. Palavras-chave: ácaros; dermatite; poeira.
Summary: Cheyletidae mites are of great importance in the veterinary sciences, as they are associated with parasitism in birds and mammals. Yet they are barely studied as etiological factors to
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
