ABSTRACT

Background: The growing contact between men and wild animals, caused by the increase in the population in urban centers and the destruction of the habitat of these animals, has been leading to a greater circulation of pathogens between humans and wildlife. Chelonoidis carbonaria, a tortoise found throughout South America, is one of the animals most rescued from animal trafficking and illegal breeding. Considering this situation, this study aimed to verify the occurrence of hemoparasites in C. carbonaria. Materials and Methods: Blood samples from 73 C. carbonaria were collected from animals located in (1) a rural commercial breeding unit, (2) an urban zoo, and (3) a center of rescued animal screening. Genomic DNA was extracted from these animals and used in PCRs to detect specific genomic fragments of haemogregarines (i.e., Hepatozoon and Hemolivia), and members of the Anaplasmataceae Family (i.e., Ehrlichia sp. and Anaplasma sp.). Blood samples were screened for hemopathogens by direct microscopy and were used for hematological assays, and serum samples were analyzed to determine the concentration of serum components. Results: It was found that 34.2% of the tortoises presented Sauroplasma sp. in their blood samples; these animals showed clinical biochemistry changes that indicate altered liver function. Two zoo animals were positive for Ehrlichia sp. in PCR, and also presented clinical biochemistry and hematological changes. Conclusion: The present project is pioneer in the detection of Ehrlichia sp. in C. carbonaria, and was able to identify changes in clinical biochemistry that can be a result of the infection by hemopathogens in this species.

ABSTRACT

This Research aimed to evaluate the metabolic status and behavior changes during the transition period in dairy goats from three breeds, under tropical conditions. Thirty multiparous female goats were kept in pens, distributed randomly by breeds. Infrared cameras were fitted in the pens to monitor the animals, and its activities were recorded. Goats displayed varied idle, standing, walking, and feeding behaviors at kidding day (P < 0.10) when compared with the days after and before. Agnostic interactions prevailed between 3.33 and 7.98% of the time on the day of kidding. There was a day effect for the exploratory activities (P < 0.10), where the most exploratory activities were observed on the day of kidding. The milk production and fat content differed according to breed and lactation week. Collective pens for lactating goats, kept in a tropical environment, do not compromise the social behavior and welfare.

ABSTRACT

Objetivou-se estudar a cinética da proteína total, fibrinogênio e ceruloplasmina durante os primeiros cinco meses de vida, em cordeiros saudáveis da raça Santa Inês, no município de São Gonçalo dos Campos, Bahia, Brasil. Amostras de sangue foram colhidas de 22 animais, ao longo de onze momentos: logo após o parto (T0), 12 (T1), 24 (T2), 48 horas (T3), sete (T4), 15 (T5), 30 (T6), 60 (T7), 90 (T8), 120 (T9) e 150 dias de vida (T10). A proteína total e o fibrinogênio plasmáticos foram analisados por meio de refratômetro clínico e pela técnica de desnaturação pelo calor, respectivamente, enquanto que a determinação da ceruloplasmina sérica se baseou em sua atividade oxidásica. Para análise estatística utilizou-se o programa SPSS versão 18; os dados com distribuição não paramétrica foram submetidos ao teste de Friedman para avaliar o efeito do tempo, enquanto que as comparações múltiplas pelo teste de Wilcoxon permitiram a identificação das diferenças entre os momentos, adotando-se nível de significância de 5% (p<0,05). A proteína total apresentou o menor valor no T0 diferindo estatisticamente dos demais tempos, com pico às 12 horas (T1), porém estabilizando-se até o final do experimento. O fibrinogênio não apresentou diferença estatística entre os tempos. De T1 (12h) a T3 (48h) constatou-se baixos valores de ceruloplasmina, muito embora às 24 horas (T2) tenha diferido estatisticamente (p<0,05), em relação ao T0. A partir do sétimo dia (T4) a concentração desta proteína aumentou significativamente, atingindo pico nos tempos T8 (90 dias) e T9 (120 dias). Foi possível estabelecer a cinética das proteínas estudadas, identificar os principais momentos com alterações e sugerir os fatores associados com as mudanças observadas.


The objective was to study the kinetics of the total protein, fibrinogen, and ceruloplasmin during the first five months of life in healthy lambs Santa Inês, in São Gonçalo dos Campos, Bahia, Brazil. Blood samples were collected from 22 animals, over eleven times: immediately after birth (T0), 12 (T1), 24 (T2), 48 hours (T3), seven (T4), 15 (T5), 30 (T6), 60 (T7), 90 (T8) 120 (T9), and 150 days of age (T10). The total protein and plasma fibrinogen were analyzed by means of a clinical refractometer and the heat denaturation technique, respectively, while the determination of serum ceruloplasmin was based on its oxidase activity. For statistical analysis, the SPSS version 18 program was used; the non-parametric data were submitted to the Friedman test to evaluate the effect of time, whereas the multiple comparisons by the Wilcoxon test allowed the identification of the differences between the moments, adopting a significance level of 5% (P < 0.05). The total protein presented the lowest value at T0 differing statistically from the other times, with a peak at 12 hours (T1), but stabilizing until the end of the experiment. Fibrinogen is not able to differentiate between the times. Between T1 (12h) and T3 (48h), low values of ceruloplasmin were observed, although at 24 hours (T2) it differed statistically (p <0.05) in relation to T0. On the seventh day (T4) the concentration of this protein increased significantly, reaching a peak at T8 (90 days) and T9 (120 days). It was possible to establish the kinetics of the proteins studied, to identify the main moments with alterations and to suggest the factors associated with the observed changes.

ABSTRACT

ABSTRACT: This study was conducted to evaluate caprine arthritis encephalitis virus (CAEV) transmission among sheep using 15 lambs that were distributed in 2 experimental groups. The exposed group consisted of 10 lambs that remained with their mothers, who were experimentally infected with CAEV. The non-exposed group was characterized as the control group and was comprised of 5 lambs that remained with their CAEV-negative mothers. Blood samples were collected monthly from birth until 1 year of life. To evaluate the transmission, an agar gel immunodiffusion test (AGID), enzyme immunoassay (ELISA), immunoblotting (IB), and nested polymerase chain reaction (nPCR) techniques were used. The non-exposed group was negative in all of the tests throughout the whole experiment. In the exposed group, 2 individuals had positive nPCR results. Positive nPCR samples were sequenced for comparison with the original goat strains and were shown to be similar to the CAEV-Cork strain. Seroconversion was not detected, and clinical manifestations were not observed. Thus, after 1 year of observation, it was verified that CAEV transmission among sheep is possible; however, with discreet frequency. This was an initial study, and other experiments are needed to analyze the adaptive capacity of the CAEV to remain in an infected sheep flock and cause the disease.


RESUMO: O estudo foi conduzido para avaliar a transmissão do vírus da artrite encefalite caprina (CAEV) entre ovinos, utilizando 15 cordeiros, distribuídos em dois grupos experimentais. O grupo exposto foi constituído por 10 cordeiros, mantidos com suas mães, que foram infectadas, experimentalmente, com CAEV. O grupo não exposto caracterizou-se como grupo controle e foi formado por cinco cordeiros, mantidos com suas matrizes, negativas para CAEV. Foram colhidas amostras de sangue mensalmente, do periodo que compreende o nascimento até um ano de vida. Para avaliar a transmissão, foram utilizadas as técnicas de imunodifusão em gel de agarose (IDGA), ensaio imunoenzimático (ELISA), immunoblotting (IB) e reação em cadeia da polimerase do tipo nested (nPCR). O grupo não exposto se manteve negativo aos testes durante todo o experimento. Já no grupo exposto, dois indivíduos apresentaram resultados positivos na nPCR. As amostras positivas na nPCR foram sequenciadas para serem comparadas com as cepas originais de caprinos, comprovando se tratar de lentivírus semelhante à cepa CAEV-Cork. A soroconversão não foi detectada e a manifestação clínica não foi observada. Sendo assim, após um ano de observação, verificou-se que a transmissão do CAEV entre ovinos é possível, entretanto, com discreta frequência. Este foi um estudo inicial, e outros experimentos são necessários para analisar a capacidade adaptativa do CAEV de permanecer em rebanho ovino infectado e, com isso, causar doença.

ABSTRACT

The objective of this study was to determine the impact of including licuri cake in the diet of Santa Inês crossbred finishing lambs by examining their liver metabolic and histopathological profile. Forty-four uncastrated lambs with an average age of 6 months and an average weight of 21.2 kg ± 2.7 kg. The animals were fed diets with 40 % Tifton 85 hay and 60 % of a mixture consisting of corn and soybean meal, 1 % urea, a mineral-vitamin premix, and an inclusion of licuri cake at a level of 0, 8, 16, and 24 % of the dietary dry matter (DM), which composed the treatments. The experimental design was completely randomized, and the data were analyzed by variance and regression analyses. The animals were confined in individual stalls for 70 days. Blood was collected on the last day of the experimental period, and metabolite, protein, energy, and enzyme profiles of the liver were determined for these samples. Histopathological evaluations of the liver parenchyma were also undertaken. The increase in the level of the licuri cake in the diet caused a linear increase (P < 0.05) in the serum urea content. The protein metabolism was not affected by the licuri cake inclusion levels in the diet. Regarding energy metabolism, a linear increase (P < 0.01) was observed in the serum triglyceride concentrations, but there were no effects on serum cholesterol levels. Regarding the functioning of the liver and muscle, the inclusion of the licuri cake had no effect on the enzymatic activities, except on gamma-glutamyltransferase, which decreased linearly (P < 0.05). The values found for the evaluated parameters varied within a range considered normal for this species. In the postmortem examination at slaughter, no macroscopic alterations in the liver were observed. Histopathological analysis revealed the presence of discrete and nonspecific alterations common to all treatments, suggesting no effect of the level of inclusion of the licuri cake. The use of the licuri cake in composing up to 24 % of the diet did not cause metabolic or liver disorders in the lambs.

ABSTRACT

Forty-five crossbred Dorper × Santa Inês lambs were selected to assess the effect of replacing soybean meal by groundnut cake metabolic profile and histopathological evaluation of the kidney and liver tissues. The animals were 5 months old on average with a 24.5 ± 5.3 kg initial body weight which were maintained fed in feedlot with groundnut cake (0, 25, 50, 75, and 100%) as the replacement for soybean meal. Confinement lasted 84 days, and on the last day, the animals were fasted and slaughtered. A completely randomized design with five treatments and nine repetitions was used. Blood samples were collected from the jugular vein of each animal to evaluate the metabolic, protein, energy, and liver profiles of lambs. No effect was observed on protein, energy, or enzymatic profiles, which remained within the normal range for sheep. A histopathological examination was performed, and no deleterious effects from groundnut cake were observed in the liver or kidney tissues. Groundnut cake as a replacement for soybean meal can be used as an alternative protein source up to 100% because it does not affect the metabolic, protein, and energy profiles or the liver and kidney functions of the growing sheep for slaughter.

ABSTRACT

The study evaluated the anthelmintic activity of aqueous extract of Zanthoxylum rhoifolium leaves in two experiments. In vitro test, cultures of goat fecal samples were treated with different concentrations of extract (134.5 to 335.0 mg.mL(-1)). In vivo test was composed of 20 sheep: G1: treated with 0.63 g.kg(-1), during four days; G2: same dose, for eight days; G3: ivermectin (200 microg.kg(-1)) and G4 untreated group. In vitro results showed a reduction of Haemonchus spp, Trichostrongylus spp. and Oesophagostomum spp. larvae greater than 95% in the concentrations between 335.0 and 193.7 mg.mL(-1). Faecal egg counting reduction was 51, 56 and 90% in G1, G2 and G3, respectively, while immature stages and adults ranged from 0 to 91% in G1 and from 26 to 94% in G2. Ivermectin effectiveness was 99% for L4 and L5 of H. contortus and 100% for other nematodes species. Clinical and biochemical parameters have remained in the normality and histophatologic analyses did not show alteration suggesting absence of toxicity. Although the great effectiveness of Z. rhoifolium leaves extract in vitro test, it displayed poor efficiency in vivo regarding gastrointestinal nematodes reduction.

ABSTRACT

O estudo avaliou a atividade anti-helmíntica do extrato aquoso das folhas de Zanthoxylum rhoifolium em dois experimentos. O teste in vitro utilizou cultivos de fezes de caprinos tratados com diferentes concentrações do extrato: (134,5 a 335,0 mg.mL-1). No teste in vivo, utilizaram-se 20 ovelhas: G1 tratado durante quatro dias (0,63 g.kg-1 PV); G2, mesma dose, por oito dias; G3, ivermectina (200 μg.kg-1); e G4, sem tratamento. In vitro, observou-se redução de larvas de Haemonchus, Trichostrongylus e Oesophagostomum superior a 95% nas concentrações de 193,7 a 335,0 mg.mL-1. In vivo, a redução de ovos por grama de fezes foi de 51, 56 e 90%, respectivamente, para G1, G2 e G3, no oitavo dia de tratamento, enquanto para os estágios imaturos e adultos variou de 0 a 91% no G1 e 26 a 94% no G2. A eficácia da ivermectina alcançou 99% para L4 e L5 de H. contortus e 100% para as demais espécies de nematoides. Parâmetros clínicos e bioquímicos permaneceram na faixa de normalidade, e as análises histopatológicas não revelaram alterações sugestivas de toxicidade. Embora altamente efetivo in vitro, o extrato aquoso de folhas de Z. rhoifolium foi pouco eficaz in vivo na redução de nematoides gastrintestinais.

ABSTRACT

Nodular trombiculinosis has been reported in Brazil in chickens [Torres, S., Braga, W., 1939. Apolonia tigipioensis, g. e sp. n. (Trombiculinae) parasito de Gallus gallus dom. Chave para determinação de gêneros. Boletim da S.A.I.C. 4, 37-44] and humans [Carneiro, L.S., 1952. Uma nova acaríase humana - Contribuição ao seu estudo. Imprensa Industrial, Recife. Faculdade de Medicina da Universidade do Recife, Tese Livre Docência, p. 56]. In this report, a juvenile ostrich and a house sparrow, both originating from a riverside property in the town of Petrolina in the state of Pernambuco, presented 87 and eight nodules, respectively, on various locations of their bodies. Physical expression of the nodules liberated parasites that were morphologically identified as mites from the family Trombiculidae. The mites were further identified as Apolonia tigipioensis by the presence of an elongated body form and transversely striated, three pairs of long legs each with seven segments, primary coxae with a single seta, each tarsus terminating with three claws, and a scutum with an anteromedian projection and paired anteromedian setae. Histopathologic examination of skin biopsies from these birds, stained with hematoxilin-eosin, revealed acute parasitic cystic lymphoplasmacytic dermatitis.

ABSTRACT

Com o objetivo de avaliar a influência da parição e do puerpério no leucograma de caprinos da raça Saanen foram colhidas 360 amostras de sangue de 20 cabras, sendo os resultados apresentados em 18 grupos experimentais: 32, 16,8,4,3,2, 1 e ½ dias antes do parto, imediatamente após aparição, ½, 1,2,3,4,8,16,32 e 64 dias após o parto. Nas amostras de sangue colhidas em frascos contendo EDTA, foram realizadas as seguintes provas: contagem do número total de leucócitos, em câmara de Neubauer modificada, utilizando-se o liquído de Thoma como diluidor e contagem diferencial de leucócitos, efetuada em esfregaços sangüíneos, corados pelo método de Rosenfeld. A avaliação dos resultados obtidos demonstrou que o leucograma sofreu influência da parição e do puerpério, sendo que durante todo o experimento o quadro leucocitário foi predominantemente neutrofilico. Nos últimos três dias de gestação observou-se gradual aumento do número de leucócitos, em decorrência das variações observadas no número de neutrófilos. No momento do parto o leucograma era caracterizado por leucocitose devido à neutrofilia associado a linfopenia. Nas primeiras 24 horas após o parto foi observado a existência de leucocitose por neutrofilia que desapereceu nos dias subseqüentes, passando o quadro leucocitário a assemelhar-se entre o 2° e 64° dia após o parto àquele observado na fase final da gestação.

ABSTRACT

Para avaliar a influência de fatores raciais sobre a função hepática de bovinos foram colhidas 134 amostras de sangue, sendo 67 animais da raça Jersey e 67 da raça Holandesa, criados em São Paulo. No soro sangüíneo realizaram-se as seguintes determinações: proteinograma; atividade enzimática da aspartato aminotransferase (AST), gama glutamiltransferase (GGT), bilirrubinas indireta, direta e total. A avaliação do proteinograma demonstrou a influência dos fatores raciais, pois os valores médios da proteína total dos bovinos da raça Jersey (6,37±0,90 g/dl) foram menores do que os animais da raça Holandesa (6,82±0,97 g/dl).Essas variações foram decorrentes as frações protéicas que correspondem as globulinas, sendo os teores médios obtidos para bovinos da raça Jersey (3,13 ± 0,81g/dl) menores do que os encontrados para bovinos da raça Holandesa (3,73 ± 0,99 g/dl). Os valores das alfa-, beta- e gama-globulinas obtidos nos animais da raça Jersey (iguais a 0,89±0,14 g/dl; 0,71±0,14 g/dl; 2,03±0,38 g/dl) foram menores do que os encontrados para bovinos da raça Holandesa (iguais a 1,00±0,16 g/dl; 0,76±0,15 g/dl; 2,20±0,45 g/dl). A avaliação da atividade enzimática revelou a influência dos fatores raciais nos resultados da AST, sendo os valores dos bovinos Jersey (49,27±17,87 U/l) maiores do que os da raça Holandesa (34,76±10,61 U/l), enquanto para a GGT não foram observadas diferenças significativas entre os resultados da raça Jersey (19,46±33,11 U/l) e da raça Holandesa (19,08±33,26 U/l). A avaliação dos teores séricos de bilirrubinas evidenciou variações sob influência racial para os teores de bilirrubinas indireta e total, sendo os valores obtidos para a raça Jersey (0,40±0,33 mg/dl de bilirrubina indireta e 0,44±0,33 mg/dl de bilirrubina total) maiores do que os observados para a raça Holandesa (0,22±0,19 mg/dl de bilirrubina indireta e 0,25±0,19 mg/dl de bilirrubina total).

ABSTRACT

Com o objetivo de avaliar a influência da parição e do puerpério sobre o eritrograma de caprinos da raça Saanen foram colhidas 360 amostras de sangue de 20 cabras, sendo os resultados apresentados em 18 momentos do puerpério: 32, 16, 8, 4, 3, 2, 1 e ® dias antes do parto, imediatamentee após a parição, ®, 1, 2, 3, 4, 8, 16, 32 e 64 dias após o parto.Nas amostras de sangue colhidas em frascos contendo EDTA, foram realizadas as seguintes determinações: contagem do número de hemácias, em câmara de Neubauer modificada, utilizando-se o líquido de Gower como diluidor; determinação do volume globular, pelo método do microhematócrito; dosagem da taxa de hemoglobina, pelo método da cianometahemoglobina e cálculo dos índices hematimétricos absolutos (VCM, HCM, CHCM). A avaliação dos resultados obtidos demonstrou que o eritrograma não sofreu influência da parição e do puerpério.


Aimine at evaluating the influence of parturition and puerperium on the erythrogram of Saanen goats (Capra hircus) 360 blood samples were collected from 20 goats on 18 different moments, as described as described: 32, 16, 8, 4, 3, 2, 1 and ® days before parturition, immediately after parturition, ®, 1, 2, 3, 4, 8, 16, 32 and 64 days after parturition. The blood samples were collected with EDTA and submitted to the following tests: erythrocyte counts (at the modified Neubauer hemocytometer, using Gower's liquid as a dilute); packed cell volume (using the microhematocrit method); hemoglobin concentration (using cyanmethemoglobin method); calculated blood indices: MCV - mean corpuscular volume; MCH - mean corpuscular hemoglobin; MCHC - mean corpuscular hemoglobin concentration. The evaluation of the erythrogram did not show any significant variation that could be attributed to the pregnancy or puerperium.

ABSTRACT

Para avaliar a influência da gestação e do puerpério sobre o eritrograma de caprinos (Capra hircus) foram coletadas 150 amostras de sangue de cabras sadias da raça Saanen, criadas no Estado de São Paulo, distribuídas em cinco grupos com 30 animais cada: G1 - cabras não prenhes; G2 - fase inicial da gestação (30 - 60 dias de prenhez); G3 - fase média da gestação (60 - 120 dias de prenhez); G4 - fase final da gestação (> 120 dias de prenhez); e G5 - recém-paridas(cabras com até 30 dias pós-parto). Nas amostras de sangue coletadas em frascos contendo EDTA, foram realizadas as seguintes análises: contagem do número de hemácias, determinação do volume globular, dosagem de hemoglobina, e cálculo dos índices hematimétricos (Volume Corpuscular Médio - VCM, Hemoglobina Corpuscular Médio - HCM, Concentração de Hemoglobina Corpuscular - CHCM). Constatou-se a influência da gestação e do puerpério sobre o eritrograma, pois na fase final da gestação, houve diminuição do número de hemácias, valores estes que retornaram no puerpério aos patamares observados nas cabras não prenhes, fases inicial e média da gestação. A avaliação do volume globular e da taxa de hemoglobina não revelou variações significativas que pudessem ser atribuídas à gestação ou ao puerpério. Na análise dos índices hematimétricos, verificou-se que os valores do VCM e do HCM foram maiores nas cabras na fase final de gestação e nas recém-paridas.

ABSTRACT

Para avaliar a influência da gestaçäo e do puerpério sobre os constituintes do leucograma de caprinos da raça Saanen foram colhidas 150 amostras de sangue, distribuídas em 5 grupos com 30 animais cada: cabras näo prenhes; fase inicial da gestaçäo (30 -- 60 dias de prenhez); fase média da gestaçäo (60 -- 120 dias de prenhez); fase final da gestaçäo (> 120 dias de prenhez); e recém-paridas (< 30 dias de puerpério). Nas amostras de sangue, colhidas em frascos contendo EDTA, foi realizada a contagem do número total de leucócitos em câmara de Neubauer, utilizando-se o líquido de Thoma como diluidor e a contagem diferencial de leucócitos,efetuada em esfregaços sangüíneos, corados pelo Método de Rosenfeld. Observou-se a influência da gestaçäo sobre o leucograma, pois o quadro leucocitário foi caracterizado por uma diminuiçäo gradual do número de leucócitos com o avançar da gestaçäo, atingindo seus menores valores no final da gestaçäo e no puerpério. Essa diminuiçäo ocorreu devido ao comportamento observado para o número absoluto de linfócitos, que também diminuiu com a evoluçäo da gestaçäo. Dessa forma, o quadro leucocitário tornou-se, predominantemente, neutrofílico na fase final da gestaçäo e no puerpério
