Abstract: Foram caracterizadas antigenicamente amostras de Salmonella isoladas de aves (portadoras e doentes) provenientes de diversas regi es do país durante o período de 1962 a 1991. Nas 2123 culturas analisadas foram reconhecidos 90 sorovares, distribuídos em 14 sorogrupos com predominancia dos grupos O:9 (40,0%), O:4 (33,3%), O:7 (10,6%) e O: 3,10 (6,7%). A maior diversidade de sorovares foi reconhecida no sorogrupo O:7 com 22 tipos distintos, secundado por O:4, O:3,10 e O:9, constituídos de 19, 15 e 10 sorotipos, respectivamente. No computo geral, foi determinada a média de 10,8 sorovares isolados por ano. Os sorovares classificados como muito frequentes nos três decênios, representando 65 a 67%, dos isolamentos, foram S. Gallinarum, S. Pullorum, S. Typhimurium, S. Heidelberg, S. Enteritidis e S. Infantis. Considera es de natureza bacteriológica e epidemiológica foram discutidas em rela o a alguns dos sorotipos prevalentes.

Abstract: the voluntary dry matter intake (dmi), rate of passage and mean retention time in the rumen and gastrointestinal tract were estimated using 18 crossbred holstein-zebu lactating cows grazing elephantgrass. the voluntary dmi and fecal output estimations the models proposed by quiroz et al. (1988) and pond et al. (1989) were used. the data of rate of passage and those of retention time in the rumen the model suggested by grovum and williams (1973) was chosen. the elephantgrass pasture were fertilized and managed in a rotational system with three days paddock occupation and 30 days resting. the stocking rate was 6 cows/ha. the dmi was estimated using the relation fecal output/forage indigestibility of extrusa samples. for the fecal production calculations, neutral detergent fiber was chromium mordanted. using the models of pond et al. (1989) and quiroz et al. (1988) to compare the total diet dmi (12.5 and 13.9 kg/cow/day) and elephantgrass dmi (7.7 and 9.2 kg/cow/day) they did not differ, respectively. however, the rate of passage and the mean retention time in the gastrointestinal tract did differ among the three used models. the results of this trial showed that the model proposed by quiroz et al. (1988) was the one that better describes the dmi data.

Abstract: in the sixties and seventies there was an extraordinary increase in export of horse meat products to europe and japan. this favored an increase in risk of salmonella outspread through those products to human and animal consumer populations. thus, from an exporting company dealing with horse meat located in northeastern brazil (state of pernambuco), 19,238 fragments of more external muscles, salmonella was isolated from 666 samples colleted from 433 animals (horses and donkeys). the serotyping of 745 isolates showed 98 serovars pertaining to 14 serogroups, predominantly classified into subspecies i (98.9%). s. anatum, s. carrau, s. saintpaul, s. agona, and s. typhimurium were the most frequent serovars isolated. preliminary data indicate that the primary causes for the presence of salmonella in the meats probably was contact with feces from slaughtered animals, as well as possible contamination of environments, in view of the absence of human carriers researched in part of the personnel.

Abstract: Foram estimados o consumo de matéria seca (MS), a taxa de passagem e o tempo médio de reten o no trato gastrintestinal de 18 vacas Holandês-Zebu, em lacta o, pastejando capim-elefante. Nas estimativas de consumo e da produ o fecal usaram-se os modelos propostos por QUIROZ et al. (1988) e POND et al. (1989). Para as taxas de passagem e tempos de reten o, incluiu-se a equa o proposta por GROVUM e WILLIAMS (1973). Nas avalia es de consumo, utilizaram-se piquetes de capim-elefante, com três dias de ocupa o e 30 de descanso, adubado com duas doses de nitrogênio (300 e 700 kg/ha/ano), numa taxa de lota o de 6 vacas/ha, em quatro meses do ano. O consumo foi estimado pela rela o produ o fecal/indigestibilidade da forragem. Nas determina es da digestibilidade e da produ o fecal foram usadas amostras de extrusas. Para a excre o fecal foi usada a fibra detergente neutra, tratada com dicromato de sódio. As estimativas do consumo de MS da dieta total e do capim-elefante n o apresentaram diferen as (P>0,05) em fun o dos modelos utilizados. Registraram-se valores médios de consumo de 12,5 e 13,9 kg de MS/vaca/dia para a dieta total e 7,7 e 9,2 kg de MS/vaca/dia do capim-elefante, respectivamente, pelos modelos de POND et al. (1989) e QUIROZ et al. (1988). As taxas de passagem, os tempos médios de reten o no rúmen e no trato gastrintestinal apresentaram diferen as, quando utilizados os três modelos testados. No presente experimento, optou-se pela ado o dos resultados obtidos pelo modelo de QUIROZ et al. (1988), para se estimar consumo, devido à semelhan a dos dados com aqueles já descritos na literatura.
