RESUMO
The ABO blood groups were determined in blood and saliva collected from 40 Aotus infulatus, 74 Saimiri sciureus, and 96 Cebus apella from the Amazonian region along the Tocantins river. Saliva samples were tested for human ABH antigens by a standard hemagglutination inhibition test. Aotus infulatus showed monomorphism, exhibiting only the B blood group. Saimiri sciureus exhibited the A (67) and AB (7) phenotypes. All four phenotypes have been found in C. apella: O (8), A (52), B (19) and AB (17). The observed distribution was as expected assuming Hardy-Weinberg equilibrium. The titers of ABH substances varied among the species and phenotypes. The B-like agglutinogen, common to all New World monkey species tested, was detected in the red blood cells. Sera were used to detect naturally occurring antibodies and the results showed discrepancies between serum and saliva phenotypes in all species studied.

Foram coletadas amostras de sangue e saliva de 93 animais da espécie Aotus nancymai e 20 de A. vociferans. As amostras de saliva foram testadas para a presença de antígenos ABH humanos, através do teste convencional de inibiçäo da hemaglutinaçäo, o qual nos permitiu classificar 21 A. nancymai e 10 A. vociferans como sendo do grupo B e 72 A. nancymai e 10 A. vociferans como pertencentes ao grupo O. Amostras de soro foram utilizadas para detectar aglutininas naturais do sistema ABO. Os resultados mostraram algumas discrepâncias entre os fenótipos séricos e salivares, como também sugeriram a existência de anticorpos anti-A1 nessas espécies

Foram coletadas amostras de sangue e saliva de 72 animais da espécie Chiropotes satanas utahicki, capturados na margem esquerda do rio Tocantins, pará (Brasil). As amostras de saliva foram testadas para a presença dos antígenos ABH humanos, através do método convencional de inibiçäo da hemaglutinaçäo. Todos os indivíduos foram classificados como pertencentes ao grupo A. Aglutininas anti-A e anti-B foram pesquisadas em 15 amostras de soro, dos quais 13 apresentaram apenas a aglutinina anti-B e duas näo apresentaram nenhum dos anticorpos. Amostras de hemácias foram testadas pelo método de eluiçäo, para verificar a presença de antígenos A e B humanos. Os resultados confirmam a presença de B-like, detectado em outros macacos do Novo Mundo e sugere a ocorrência de A-like

Concentrations of chorionic gonadotrophin gradually increased during early pregnancy, reached maximum values at mid-gestation, then declined to low levels. Oestradiol-17 beta concentrations were relatively low (300-600 pg/ml) during early pregnancy, increased thereafter to high levels (10-35 ng/ml), and then appeared to decline towards term. Concentrations of progesterone were constant (100-200 ng/ml) for the first 15 weeks of gestation, suggesting that sequential measurements of progesterone could be used to diagnose early pregnancy. Prolactin concentrations rose during pregnancy, reaching maximum values at term.

Twenty-five clinical and biochemical parameters were determined on 17 normal, male, laboratory-bred Bolivian squirrel monkeys (Saimiri sciureus). Parallel hematologic parameters were conducted. The correlation of biochemical and hematological observations and the distribution characteristics, range, and standard error of the mean were determined. The purpose of the present communication is to establish baseline biochemical values for laboratory-bred squirrel monkeys and to present a correlative comparison between selected cellular elements and major blood electrolytes.

Eighty-one black-handed tamarins from the Tucurui region were tested for human type ABO blood groups by salivary inhibition tests. Eleven belonged to the A group, 45 to B, and 25 to AB. The serum samples were tested for the presence of agglutinins having specificities like those of humans. The ABO system appeared to be polymorphic, with three alleles occurring at the following frequencies: A = 0.26, B = 0.66, and O = 0.08. The observed distribution fitted the expected on the basis of Hardy-Weinberg equilibrium.

Serum measurements of chorionic gonadotropin (CG), estradiol (E-2) and progesterone (P) were used to describe patterns of hormonal change in Bolivian squirrel monkeys undergoing spontaneous abortion. During early pregnancy, serum CG levels gradually increased, reaching maximum levels at the end of the first 50 days of pregnancy (range: 200-1964 ug protein/ml). E-2 concentrations also increased to high levels (10-30 ng/ml) toward the end of pregnancy, while serum P remained fairly constant at levels above 100 ng/ml. A gradual decline in serum hormone concentrations was observed in aborting animals. CG levels declined to less than 100 ug protein/ml while E-2 and P decreased to concentrations characteristic of nonpregnant cycling animals, less than 500 pg/ml and 20 ng/ml respectively. The data suggest that two weekly measurements of CG and E-2 could be used to identify monkeys undergoing abortion and those which have already aborted.

Complete and differential blood counts were conducted on 23 male squirrel monkeys (Saimiri sciureus) of Bolivian origin. The sample included 9 laboratory-bred and 14 wild-caught adult monkeys weighing between 600 and 1,500 g. The means of total white blood cell (WBC) counts, total hemoglobin and hematocrits of laboratory-bred animals were found to be significantly different from those of wild-caught monkeys (p less than 0.01). Other hematologic parameters showed no significant differences between the two experimental groups. 3 of 14 (21.0%) wild-caught animals each had 1 reactive lymphocyte and 7% of the same group had 10 nucleated erythrocytes per 100 WBC. No reactive lymphocytes or nucleated erythrocytes were observed in laboratory-bred animals. The importance of these baseline data and the basis for the differences observed between laboratory and wild-caught monkeys are discussed within the context of experimental studies involving primates in which hematologic parameters are valuable.
