ABSTRACT

Dentre os crocodilianos com ocorrência no Brasil, o Caiman crocodilus (Linnaeus, 1758) é a espécie de maior frequência, porém sua presença em estudos científicos restringe-se a levantamentos faunísticos, na maioria das vezes. O leucismo, também conhecido como albinismo parcial, é uma anomalia cromática ainda pouco conhecida. Indivíduos portadores dos genes que condicionam a doença apresentam ausência de pigmentação em uma parte ou em todo o corpo, porém os olhos não apresentam alteração. O objetivo deste trabalho foi realizar o primeiro registro de Caiman crocodilus com leucismo no mundo.(AU)


Among crocodilians in Brazil, Caiman crocodilus (Linnaeus, 1758) is the most frequent species, but its presence in scientific studies is mostly restricted to faunal surveys. Leukism, also known as partial albinism, is a still little known chromatic anomaly. Individuals with genes that condition the disease present no pigmentation in one part or in the whole body, but the eyes did not change. The objective of this work was to perform the first record of Caiman crocodilus with leucismo in the world.(AU)

ABSTRACT

This study aimed to verify if random regression models using linear splines (RRMLS) are suitable for identifying genetic parameters in multiple-breed populations and also to investigate whether an interaction exists between the breeding value (BV) of sires and their progeny breed group. Ten populations were simulated by crossing 2 breeds with distinct genetic variance and nonzero segregation variance. To obtain the genetic parameters, 2 models were used: a multiple-trait model (MULT), in which the trait was considered distinct when evaluated in each group (1/2P1 + 1/2P2, 5/8P1 + 3/8P2, and 3/4P1 + 1/4P2), and a RRMLS with the spline polynomial knots adjusted to these same groups. The genetic parameters estimated through MULT and RRMLS did not differ from the simulated values. The correlations between BV (simulated and estimated) of animals were high and varied from 0.74 to 0.76, which indicates the efficiency of using MULT and RRMLS for predicting BV. Using field data, the traits age at first calving (AFC), first lactation length (LL), and 305-d milk yield (MY-305) from a multiple-breed population of Holstein-Gyr cattle were analyzed. The BV of animals were modeled through RRMLS with 3, 5, and 7 knots, distributed in accordance with the fraction of Holstein breed in each progeny breed group. It was verified that RRMLS with 7 knots for adjusting mean trajectories and genetic effects, with homogeneous residual variance, best fit AFC and LL. For MY-305, the best fit for mean trajectory and genetic effects was the RRMLS with 5 knots and with homogeneous residual variance. The posterior means of heritability varied from 0.21 to 0.48, 0.21 to 0.38, and 0.10 to 0.33 for AFC, LL, and MY-305, respectively. Estimates from genetic parameters obtained by using RRMLS with field data showed that this model is a useful tool for genetic evaluations of populations formed by a great number of breed groups. An interaction occurred between the BV of sires and their progeny breed group, and the genetic parameters for AFC, LL, and MY-305 traits from a multiple-breed population depend on breed composition of the progeny from which the evaluations are based.

ABSTRACT

Objetivou-se verificar se a utilização do modelo autorregressivo (MAR) é adequada para obtenção de parâmetros genéticos para produção de leite no dia do controle (PLDC) de bovinos leiteiros da raça Gir. Foram analisados 125.191 registros de produções diárias, nas três primeiras lactações, por meio dos modelos de repetibilidade (MREP) e MAR. No MREP, foi considerado o efeito de ambiente de curto prazo; no MAR, foi considerado, também, o efeito de ambiente de longo prazo. Os modelos foram comparados por meio do logaritmo da função de máxima verossimilhança (−2logL) . A herdabilidade estimada pelo MREP foi 0,18; no caso do MAR, as estimativas para primeira, segunda e terceira lactações foram 0,32, 0,28 e 0,26, respectivamente. A estimativa de autocorrelação dos componentes de variância de longo prazo foi próxima de zero, e as de curto prazo foram de alta magnitude para primeira (0,79), segunda (0,79) e terceira (0,81) lactações. Logo, a influência do ambiente de curto prazo dentro de cada lactação não é a mesma. O valor de −2logL mais próximo de zero foi obtido para o MAR (-294.884,7778) em relação ao MREP (-329.266,4810). Assim, o MAR é adequado para obtenção de estimativas de parâmetros genéticos para PLDC nas três primeiras lactações de bovinos leiteiros.(AU)


Aimed to verify if the autoregressive model (MAR) is adequate to obtain genetic parameters for Gyr dairy cattle milk yield on the test day in the three first lactations. Analysis was performed on 125,191 records of daily production of 9,242 cows using repeatability model (MREP) and MAR. On MREP, a long-term environment was considered, on MAR, the short-term environment was also taken into consideration. The models were compared by logarithm of the maximum likelihood function (−2logL) . The heritability estimated using the MREP model was 0.18, while the heritability estimated by MAR for first, second, and third lactations were 0.32, 0.28 and 0.26, respectively. The autocorrelation estimates of the components of long-term variance were close to zero, and those of the short-term were of high magnitude for first (0.79), second (0.79) and third (0.81) lactations. Therefore, the influence of the short-term environment within each lactation is not the same. The value of −2logL closer to zero was obtained for MAR (-294,884.7778) in relation to MREP (-329,266.4810). Thus, MAR is suitable for obtaining genetic parameters estimates for PLDC in the first three lactations of dairy cattle.(AU)

ABSTRACT

Criadores de animais silvestres sempre buscam métodos eficientes de manter sua criação. Parasitos intestinais afetam os animais em cativeiro, diminuindo sua sobrevivência e reprodução. Este estudo teve como objetivo avaliar a eficácia do uso de cal virgem na desinfecção do solo e na prevenção da reinfestação de endoparasitos em pacas (Cuniculus paca) em cativeiro. Amostras de solo das baias de criação foram analisadas usando-se o método de Rugai modificado. Duas etapas foram avaliadas: a primeira aos cinco, 45 e 105 minutos após os tratamentos, e a segunda aos sete dias e aos 14 dias após os tratamentos. Os valores de pH das amostras foram verificados após a aplicação de quatro tratamentos. Foram aplicados 400g/m2 de cal virgem a lanço ou 500mL/m2 de três soluções de cal virgem (10%, 20% ou 40% p/v). Na primeira etapa, a cal a lanço foi ineficaz na modificação do pH do solo e no controle de parasitos. A solução a 10% proporcionou o melhor controle dos parasitos. Na segunda etapa, as soluções foram eficazes na elevação do pH, porém não houve diferença significativa nos achados larvais. Concluiu-se que, nas condições do estudo, a solução a 10% aumentou o pH do solo e teve boa capacidade de inativação dos ovos de Strongyloides sp., o que economicamente é interessante. Porém, para o controle eficiente de Strongyloides sp. em cativeiros de pacas, deve-se considerar a frequência da aplicação de soluções com até 20% de cal, juntamente com a adoção de um programa de vermifugação.(AU)


Wild animal breeders are always looking for effective ways to care for their livestock. Intestinal parasites affect animals in captivity, reducing their survival and reproduction. This study aimed to evaluate the effectiveness of quicklime for use in soil disinfection and prevention of reinfection of endoparasites in paca (Cuniculus paca) kept in captivity. Soil samples of pacas' stalls were analyzed using the modified Rugai method. Two experimental stages were evaluated; the first at 5, 45 and 105 minutes after treatment and the second at 7 days and 14 days after treatment. The pH values of the samples were checked after the application of four treatments. An application of 400g/m2 of quicklime spread out on ground or 500mL/m2 of three lime solutions (10%, 20% or 40%, w / v) applied on ground. In the first stage, the lime spread out on soil was ineffective in parasites control, while the 10% solution provided the best control of parasites. In the second stage, the solutions were effective in raising the pH, but there was no significant difference in larval findings. In conclusion, under the conditions of the study, 10% solution increased the soil pH and had good ability to inactivate the eggs of Strongyloides sp.; that is economically interesting. However, for effective control of Strongyloides sp. in pacas kept captive, both the frequency of application of solutions up to 20% of lime and the adoption of a good worming schedule should be taken into consideration.(AU)

ABSTRACT

Com o objetivo de definir os valores biométricos e quantificar parâmetros hematológicos como hematócrito, concentração de proteínas plasmáticas totais e leucócitos totais de tartarugas da espécie Podocnemis expansa, coletou-se um mililitro de sangue da veia femoral de 60 exemplares aparentemente saudáveis. Os animais obtidos do criatório particular, Estância Terra, localizado no estado do Acre, foram classificados em seis grupos de pesos diferentes. Durante a biometria, foram tomadas medidas de peso, comprimento e largura da carapaça e do plastrão, para as análises da correlação dos parâmetros de tamanho e massa corporal entre os indivíduos do mesmo grupo. Os valores observados indicaram que o grupo 06, que inclui os animais com massa acima de 26 kg, apresentou melhor correlação entre as massas individuais de cada animal (r = 0,97) Enquanto que, o grupo 02 (massa entre 21 e 25 kg) apresentou a pior correlação entre as massas (r = 0,34). O resultado da média total de hematócrito de todos os animais deste experimento foi de 10,56%. A concentração das proteínas plasmáticas totais foi de 3,69g dL-1, e a média de leucócitos totais foi de 51466,66µL. Estes parâmetros são considerados fora do padrão quando comparados com os valores encontrados em animais saudáveis da mesma espécie. Assim, este trabalho pode contribuir com informações sobre os dados biométricos e parâmetros hematológicos de P. expansa de cativeiro e demonstra a importância do monitoramento da sanidade dos animais em cativeiro, prevenindo manifestação de enfermidades que poderão pôr em risco a saúde de todo o plantel.(AU)


The aim of this study was defined the biometric values and quantify hematological parameters such as hematocrit, concentration of total plasma proteins and total leukocytes for Podocnemis expansa, we collect one milliliter of blood from the femoral vein of 60 specimens apparently healthy. The animals were collected from a private farm, Estancia Terra, located in Rio Branco in the state of Acre, and were classified into six groups of different weights. During the collection of biometric data, weight measurements were taken, and length and width of the carapace and plastron, for the analysis of correlation between the size parameters and body mass between individuals of the same group. The values observed indicate that the group 06, which includes animals with mass above 26kg, showed the best correlation between the individual masses of each animal (R = 0.97), while the group 02 (weight 21 to 25kg) showed the worst correlation between the mass (r = 0.34). The result of the overall average hematocrit of all animals of this experiment was 10.56%. The concentration of total plasma proteins was 3,69g DL-1 and the average total number of leukocytes was 51466,66µL. These parameters are considered abnormal when compared to the values found in healthy animals of the same species. This work contributes with information about biometric data and hematological parameters of P. expansa captivity and demonstrates the importance of monitoring health, preventing diseases that may endanger the health of all animals in the farm.(AU)

ABSTRACT

Angiostrongylus vasorum is a parasitic nematode that infects the heart and pulmonary artery and its branches of domestic and wild canids. The parasite can use several species of terrestrial and aquatic molluscs as intermediate hosts, although susceptibility varies. Pomacea canaliculata is a mollusc found in lakes, swamps and rivers in South America. In this study, we evaluated the susceptibility, parasite growth, oviposition and larval development of 282 P. canaliculata infected with 500 A. vasorum first-instar larvae (L1). From day 5 post-infection (pi) to day 30 pi, seven specimens per day were sacrificed to recover the larval instars. We compared 50 egg masses from infected and uninfected molluscs to determine the number of eggs per clutch, the hatching rate and the growth of the molluscs. The percentage of recovered larvae ranged from 39.17% to 67.5%. First-stage larvae (L1) were found until day 19 pi, second-stage larvae (L2) were found from days 11 to 25 pi, and third-stage larvae (L3) were recovered only after day 19 pi. Infected snails exhibited the most eggs during spawning, although the rate of hatching and shell size were lower in the infected snails compared with controls. This is the first report of an experimental infection of P. canaliculata with A. vasorum, and the results confirm the non-specificity of the nematode in relation to the intermediate host and indicate the importance of epidemiological surveys of this parasite and mollusc.

ABSTRACT

Considering the venereal transmission of visceral leishmaniasis from dogs to bitches, the aim of this study was to verify if the penile surface and smegma from infected dogs can be the source of parasites in bitches. Twelve Leishmania infantum infected dogs had semen and smegma samples collected for submission to PCR identification of the DNA of the parasite. Semen (41.7 percent) and smegma (50.0 percent) have similar positive incidence (P>0.05; Fisher's exact test), with 58.3 percent of the dogs positive for semen and/or smegma samples. The proportion of positivity for both semen and smegma was 33.3 percent, but 8.3 percent was positive only for semen, and 16.7 percent only for smegma, revealing a moderate agreement between tests (K=0.5; Kappa index). It was concluded that Leishmania infantum is present in the smegma of contaminated dogs and it can be a source of parasites for the semen and the bitch...


Tendo em vista a transmissão venérea da leishmaniose visceral do cão para a cadela, o objetivo deste estudo foi verificar se a superfície peniana e o esmegma de cães infectados poderiam ser a fonte de parasitas para a fêmea. Amostras de sêmen e esmegma de 12 cães infectados com Leishmania infantum foram submetidas à identificação do DNA do parasita por PCR. As incidências de positividade no sêmen (41,7 por cento) e no esmegma (50,0 por cento) foram semelhantes (P>0,05; teste exato de Fisher), sendo 58,3 por cento dos cães positivos para sêmen e/ou esmegma. A positividade para sêmen e esmegma juntos ocorreu em 33,3 por cento, mas em 8,3 por cento dos casos apenas no sêmen, e em 16,7 por cento apenas no esmegma, o que revela uma concordância moderada entre os testes (K=0,5; índice Kappa). Conclui-se que a Leishmania infantum está presente no esmegma de cães contaminados, podendo ser a fonte de parasitas para o sêmen e a cadela...

ABSTRACT

Bronchoalveolar lavage (BAL) is a procedure that retrieves cells and other elements from the lungs for evaluation, which helps in the diagnosis of many pulmonary diseases. The aims of this work were to perform this procedure in dogs in the acute and chronic phases of an Angiostrongylus vasorum infection for cytological analysis and to evaluate the potential of this technique as a diagnostic method for this lung-heart worm. The BAL procedure was performed through the use of an endotracheal tube on seven A. vasorum infected dogs and on five non-infected dogs lined as a control group. Sixty days post-infection (dpi) active and live larvae were retrieved from the bronchoalveolar fluid (BALF) of all infected dogs. Furthermore, in one animal it was possible to retrieve larvae in its BALF before the pre-patent period. This work reports that the A. vasorum infection resulted in an increase of relative neutrophils and eosinophils counts. In contrast, there was a significant decrease in the alveolar macrophage relative count in infected animals from 60 to 330 dpi. This study shows that the BAL is an accurate technique for the diagnosis of canine angiostrongylosis. Moreover, the technique allows us to retrieve cells and other elements that line the lung surface for cytological evaluation, which provides information about inflammatory diseases, and the diagnosis and prognosis of pulmonary parasites such as A. vasorum.

ABSTRACT

During gonadal maturation the females of Steindachnerina insculpta, a teleost of the Furnas reservoir, Minas Gerais, Brazil, show low hepatosomatic and high gonadossomatic indexes, suggesting possible transference of hepatic substances to the ovaries. In comparison to the resting phase, in the maturation/mature one the hepatocytes show greater development of both smooth and rough endoplasmic reticula, increased electron density in the mitochondria, and glycogen scattered throughout the cytoplasm. In both resting and maturation/mature phases, the hepatic parenchyma contains melanomacrophagic centers that consist of degenerating cellular debris and are surrounded by capsules formed by cells, resembling fibroblasts, joined by desmosomes. No physiological relation of these centers with ovarian maturation was found.


Fêmeas de Steindachnerina insculpta, um teleósteo do reservatório de Furnas, Minas Gerais, Brasil, apresentaram, durante a maturação gonadal, um baixo índice hepatossomático e um alto índice gonadossomático, sugerindo que substâncias hepáticas são provavelmente transferidas para os ovários. Comparando-se fêmeas no estádio de repouso com aquelas no estádio maturação/maduro, observaram-se nos hepatócitos de fêmeas no estádio maturação/maduro maior desenvolvimento do retículo endoplasmático rugoso e liso, mitocôndrias com densidade eletrônica aumentada e glicogênio espalhado por todo citoplasma. No estádio de repouso, assim como no estádio de maturação/maduro, observaram-se, no parênquima hepático, centros melanomacrofágicos constituídos de restos celulares em degeneração delimitados por cápsula contendo células semelhantes a fibroblastos unidas por desmosomas. Não foram observadas relações fisiológicas entre os centros melanomacrofágicos e a maturação dos ovários.

ABSTRACT

BACKGROUND: The current management of patients with gallstone disease and ductal calculi consists of endoscopic stone extraction (ESE) followed by laparoscopic cholecystectomy (LC). Following the advent of techniques of laparoscopic ductal stone clearance, an alternative single-stage laparoscopic treatment was introduced for these patients. The European Association of Endoscopic Surgery (E.A. E.S.) set up a ductal stone trial to compare the relative efficacy and outcome of these two management options. METHODS: A prospective randomized controlled clinical trial compared two management options. Group A (n = 150) received preoperative endoscopic retrograde cholangiography (ERC) with ESE followed by LC during the same hospital admission, and group B (n = 150) received single-stage laparoscopic management. RESULTS: There were no significant differences between the two groups in the clinical demographic details and the pretreatment biochemical findings. In group A, 14 of 150 patients received single-stage treatment; in group B, 17 of 150 were managed by the two-stage approach (protocol violation = 31/300, 10%). In group A patients managed in accordance with randomization, ERC was successful in 129/136 (95%) and preoperative ESE succeeded in 82/98 (84%) with ductal calculi detected by the ERC. Two patients had malignancies and one refused surgery. Thus, 133 patients underwent surgery. Of this group, 116 had LC only and 17 had LC and attempted laparoscopic duct exploration. There were eight conversions to open surgery (6%), 17 complications for both stages (12.8%), and two postoperative deaths (1.5%). In group B patients managed in accordance with randomization, intraoperative cholangiography was successful in 132/133 (99%). Twenty-one (16%) had normal findings, ductal calculi were found in 109, and other pathology was noted in two (periampullary cancer, severe pancreatitis). These two patients and one other (who had gross adhesion in the triangle of Calot) were converted at the start of the procedure. Transcystic ductal stone clearance was successful in 45 of 56 patients (80%), and laparoscopic direct common duct (CBD) exploration was successful in 47 of 55 patients (85%). This group includes 53 patients who underwent primary direct exploration and two failed attempts at transcystic extraction. The conversion rate was 13%. Postoperative complications were encountered in 21 patients (15.8%), and one patient died of a major myocardial infarction (0. 75%). The one postoperative death and the 10/11 biliary complications occurred in the laparoscopic supraduodenal CBD exploration subgroup. The conversion rate was higher in group B (17 vs eight; p = 0.08). Laparotomy in the postoperative period was required in three patients in group A and four patients in group B. The group B patients were in hospital for 3 days less than patients who had two-stage management (median, 6.0, IQR = 4.25-12 vs median, 9.0, IQR = 5.5-14; p < 0.05). CONCLUSIONS: The results demonstrate equivalent success rates and patient morbidity for the two management options but a significantly shorter hospital stay with the single-stage laparoscopic treatment. The findings indicate that in fit patients (ASA I and II), single-stage laparoscopic treatment is the better option, and preoperative ESE should be confined to poor-risk patients-i.e., those with cholangitis or severe pancreatitis.

ABSTRACT

BACKGROUND: The current management of patients with ductal calculi and gallstone disease consists of endoscopic stone extraction (ESE) followed by laparoscopic cholecystectomy (LC). The advent of techniques of laparoscopic ductal stone clearance has introduced an alternative single stage laparoscopic treatment for these patients. The EAES ductal stone trial was set up to compare the relative efficacy and outcome of these two management options. METHODS: The study consists of a prospective randomized controlled clinical trial comparing two management options of patients undergoing LC and suspected of harbouring common duct stones. Patients registered into the trial are randomized to one of two arms: (i) Group A-preoperative ERC with ESE followed by LC during the same hospital admission. (ii) Group B-single stage laparoscopic management consisting of LC and laparoscopic stone extraction either by the trans-cystic duct route or by direct supraduodenal common duct exploration. RESULTS: This preliminary analysis was carried out on 207 randomized patients with comparisons being made on the intention to treat principle. The two groups (A = 106, B = 101) were comparable with respect to clinical features. ASA grade, serum biochemistry and ultrasound findings. CONCLUSIONS: These preliminary findings indicate equivalent success rates and patient morbidity between the two management options but a shorter hospital stay (cost benefit) with the single stage laparoscopic treatment. Trans-cystic duct extraction is a more benign procedure than laparoscopic supraduodenal CBD exploration and is accompanied by a significantly shorter hospital stay. The higher incidence of conversion in the single stage laparoscopic group compared to the two-stage arm is due to the preference for open common duct exploration when the laparoscopic attempt failed by the majority of participating surgeons. The results to-date suggest that in fit patients, single stage laparoscopic treatment is the better option and the role of ESE should change to selective use in those patients in whom laparoscopic ductal stone extraction has failed.

ABSTRACT

A case of neuromotor retardation in association with chromosome 1qh's reported. Chromosomes analysis of the patient and three relatives showed increased long arm on the n. degrees 1 chromosome, in all of them. However it is wmphasized that the clinical feautre could be secondary to various non genetics factors, also.

ABSTRACT

An unusual case of mental retardation and physical malformations with chromosome abnormalities in a 9 year old boy is reported. Chromosomal analysis showed either breakage and delation from some gens to 5p and/or 13q; genic mutation or, perhaps, efect of position in re-adjusted chromosomic segments.
