BIOCHEMICAL VARIABILITY BETWEEN VENOMS FROM DIFFERENT HONEYBEE (APIS-MELLIFERA) RACES

1. The comparison of molecular exclusion cromatography profiles of venoms from sting apparatuses of Apis mellifera ligustica, Apis mellifera adansonii and Africanized honey-bees in Sephadex G-100 revealed both qualitative and quantitative differences.2. The venoms from A.m. ligustica and A.m. adansonii presented, respectively, three and two peaks characteristic of each sub-species, while Africanized honey-bee was characterized by the absence of eight peaks common to the former.3. The polypeptides with M(r) in the range from 100,000 to 7500 da correspond respectively to 62.0%, 66.6% and 68.7% of total proteins from the venon of A.m. ligustica, A.m. adansonii and Africanized honey-bees, while the peptidic fraction with M(r) range from 4100 to 2000 da corresponds to 11.4%, 32.4% and 10.2% of venom protein, respectively.

Hematological, biochemical and anatomopathological aspects of the experimental infection with Trypanosoma evansi in dogs

O presente estudo acompanhou durante 82 dias o curso da infecção experimental com T. evansi em quatro cães, realizando a avaliação dos achados hematológicos, bioquímicos e anatomopatológicos. Os animais infectados mostraram declínio acentuado na contagem de hemácias, hematócrito e teor de hemoglobina, permanecendo anêmicos a partir da terceira semana de infecção até o final do período experimental. Leucopenia com neutropenia foram observadas entre a segunda e a quinta semanas após a infecção. Os cães inoculados desenvolveram hiperproteinemia, sendo constatada diminuição na relação albumina:globulina. As atividades séricas de alamina aminotransferase e aspartato aminotransferase aumentaram significativamente nos cães infectados em relação aos animais controle. O exame histopatológico revelou hiperplasia linfóide no baço e linfonodos e infiltrado mononuclear periportal e esteatose de padrão centrolobular no fígado de todos os cães infectados. Intenso infiltrado mononuclear foi observado no miocárdio de três cães e acúmulos de células mononucleares junto às meninges foram evidenciados em dois animais infectados.

Experimental Trypanosoma evansi infection in donkeys: hematological, biochemical and histopathological changes

Cinco jumentos, adultos foram infectados experimentalmente com cepa brasileira de Trypanosoma evansi, isolada de um cão naturalmente infectado, com o intuito de observar as alterações hematológicas, bioquímicas e histopatológicas durante a evolução da enfermidade. O curso da infecção experimental foi de 145 dias. Análise hematológica dos jumentos infectados revelou declínio nos valores de hemoglobina, hematócrito e contagem total de eritrócitos. Notou-se anemia após sucessivos picos de parasitemia. Análise bioquímica indicou aumento dos níveis de índice ictérico, globulinas séricas e diminuição dos valores séricos de albumina e glicose. Todos os jumentos infectados apresentaram aumento do baço e de sua polpa branca, aumento de linfonodos mediastínicos e congestão pulmonar. Meningoencefalite foi o principal achado histopatológico. em algumas áreas do pedículo cerebelar foram observadas desmielinização, além de vacuolização do neurópilo. O estudo mostrou que jumentos infectados com a cepa brasileira do T. evansi desenvolveram doença crônica.

Haematological and biochemical reference intervals for farmed channel catfish

The reference intervals for biochemical variables and red blood cell indices of healthy intensively bred channel catfish Ictalurus punctatus were determined. The blood variables were determined using standardized clinical methods. The reference intervals (25th and 75th percentiles) were established using a non-parametric method. Reference intervals for plasma glucose, serum total protein, sodium, potassium, calcium, magnesium, chloride concentration, primary and secondary red blood cell indices were established. The haematological and biochemical reference intervals established may allow important clinical decisions about channel catfish.

Genetics of resistance to powdery mildew (Microsphaera diffusa) in Brazilian soybean populations

Crosses between resistant and susceptible soybean cultivars were performed and the F2 populations were obtained to study the inheritance of soybean resistance to powdery mildew and to estimate the number and action of genes related to resistance. The reaction to powdery mildew was studied in a greenhouse and pots carrying plants with symptoms were distributed among the pots carrying the genotypes to be tested as a source of inoculum. Individual plants were scored according to the method of Yorinori (1997), with modifications, and classified as resistant or susceptible. The results showed that adult soybeans plants can present resistance to powdery mildew, which is controlled by one major gene with a dominant effect.
