brucellosis in childhood.brucellosis has always been an unusual disease in children and, concomitant with the control of the disease in domestic animals, reports have become sparse. the pediatrician, therefore, may not be aware of the protean clinical manifestations of childhood brucellosis. in 1973, nine cases occurred during a three-month period in el paso, texas. all cases were marked by spiking fevers and lethargy of four days to four weeks in duration. tender hepatomegaly or splenomegaly was striking in seven patie ...1975806883
serologic evidence of venezuelan equine encephalitis in some wild and domestic populations of southern texas.more than 2,500 sera from approximately 30 wild and domestic species in southern texas were tested for neutralizing antibodies to venezuelan equine encephalitis (vee). virus isolations were also attempted from blood and tissue samples of many of the wild specimens. vee neutralizing substances were present in a variety of species collected prior to the 1971 epizootic, suggesting that vee was present and perhaps enzootic in this area before the recent epizootic. serologic results of this study sug ...1975238050
teaching international animal agriculture.students who major in animal science at u.s. institutions are generally exposed to a curriculum that emphasizes commercial, large-scale production of the few traditional food animals: cattle, poultry, sheep, and swine. globally, most farmers live in lesser-developed countries under limited-resource conditions of land, feed supplies, equipment, and capital. the promotion of commercial animal production enterprises may not be appropriate for such farms because it can subject farmers to considerabl ...199910568483
