Characterization of eight new phlebotomus fever serogroup arboviruses (Bunyaviridae: Phlebovirus) from the Amazon region of Brazil.
Eight new members of the phlebotomus fever arbovirus serogroup (family Bunyaviridae; genus Phlebovirus) from the Amazon region of Brazil are described. One serotype was recovered from a febrile patient, three from small wild animals and four from sand flies. A small serum survey carried out with the human isolate, Alenquer virus, suggests that it rarely infects man. ⋯ This finding is of considerable interest and deserves further investigation. Addition of these eight new viruses to the genus Phlebovirus brings to 14 the number of serotypes known to occur in the Amazon region and to 36 the total number reported worldwide. More detailed clinical and epidemiological studies should be conducted in Amazonia in order to define the public health impact caused by phleboviruses.

Case ReportsA case of encephalitis in a human associated with a serologic rise to Jamestown Canyon virus.
An 8-year-old girl living in rural southwestern Michigan experienced sudden onset of symptoms beginning with headache, dizziness and fever which rapidly progressed to central nervous system involvement with seizures and coma. Following 27 days of hospitalization her recovery was uneventful, with no apparent sequelae 15 months after discharge. Serologic studies of paired sera showed a rise in antibody to Jamestown Canyon virus, a member of the California serogroup (family Bunyaviridae). ⋯ A concomitant rise in complement fixation antibody to herpesvirus was also noted. We believe this is the first reported case of encephalitis associated with Jamestown Canyon virus infection. Reasons are presented for the current inability to routinely detect infection and clinical illness caused by this virus.

Case ReportsEosinophilic meningoencephalitis in Cuba, caused by Angiostrongylus cantonensis.
Five cases of eosinophilic meningoencephalitis presumed to be caused by the rat lungworm, Angiostrongylus cantonensis, are reported from localities in or near Havana, Cuba. The first typical case occurred in 1973. Lungworms identified as A. cantonensis were found in rats from the same localities. The clinical picture in the Cuban cases, as in cases from other countries, is that of a self-limiting disease without apparent sequelae.

Further experience with mebendazole in the treatment of symptomatic trichuriasis in children.
Mebendazole (methyl-5-benzoylbenzimidazole-2-carbamate: Vermox), a broad spectrum anthelmintic, cured 22 (88%) children with symptomatic trichuriasis when given as a single 6-day course in a dosage of 100 mg twice daily. A further 3 (12%) were cured after a repeat 6-day course of therapy. ⋯ The administration of an antidiarrheal agent, loperamide hydrochloride (Imodium), appeared to enhance the efficacy of mebendazole. Both drugs were well tolerated and completely free of any toxic effects.
