ABSTRACT

This report describes a fatal case of a pet dog with major enteric signs owned by a family that has experienced cases of pulmonary tuberculosis (TB) in the household. Clinical and epidemiological aspects, imaging data, microbiological, haematological and histopathological examinations were assessed to diagnosis of disease. gyrB-RFLP, spoligotyping and MIRU-VNTR allowed molecular detection of M. tuberculosis strain from S family. The resazurin microtiter assay indicated that all isolates were resistant to isoniazid, ethambutol, ciprofloxacin, ofloxacin, streptomycin and amikacin. The public health concerns related to canine tuberculosis and risk of the dissemination by pets of M. tuberculosis pre-multidrug-resistant (PMD) to isoniazid, ethambutol and other first-line drugs used in human therapy of TB are discussed. We believe this to be the first report of PMD M. tuberculosis infection in a dog presenting mainly enteric manifestation, confirmed as S lineage by molecular methods, owned by a family in which TB has spread in the household for generations.

ABSTRACT

A coloração pela prata das regiões organizadoras de nucléolos (NORs) é caracterizada por marcar proteínas ligadas ao ácido ribonucleico ribossômico, avaliando a proliferação em células normais ou neoplásicas. Objetivou-se estudar, em testículos de ovinos obtidos em matadouro, a validade do uso da técnica de coloração pela prata (AgNOR) na identificação das regiões organizadoras de nucléolo (NORs) em células saudáveis da linhagem espermatogênica. Utilizaram-se 43 pares de testículos de ovinos mestiços entre seis e 10 meses de idade. Testes de Wilcoxon e Spearman foram empregados, com nível de 5%. As médias das NORs nas células das gônadas direita e esquerda foram, respectivamente: espermatogônia (8,77±1,14 e 9,04±0,96), espermatócitos (4,99±2,00 e 6,20±2,07; P<0,05), Leydig (8,05±2,82 e 7,89±2,29) e Sertoli (8,07±1,88 e 7,61±2,16; P<0,05). Houve correlação (P<0,05) entre os lados para o número de NORs: espermatócitos x Leydig (0,49); espermatócitos x Sertoli (0,49) e Leydig x Sertoli (0,96). Conclui-se ser válido o emprego da técnica AgNOR para avaliar o potencial proliferativo das células saudáveis em testículos de ovinos com prática execução e baixo custo.(AU)


The silver staining technique for AgNOR nucleolar organizer regions (NORs) is characterized by marking proteins linked to the ribosomal ribonucleic acid, evaluating cell proliferation. The aim was to study the validity of the AgNOR staining technique in the testicular cell proliferation in crossbred ovine. Forty-three pairs of ovine testicles between 6 and 10 months old were collected. Wilcoxon and Spearman tests were used with a significance level of 5%. The mean NORs count in cells of the right and left gonads were respectively: spermatogonia (8.77±1.14 and 9.04±0.96), spermatocytes (4.99±2.00 and 6.20±2.07, P<0.05), Leydig (8.05±2.82 and 7.89±2.29) and Sertoli cells (8.07±1.88 and 7.61±2.16; P<0.05). There was a correlation between the mean values for the right and left sides for the number of NORs (P<0.05) between Leydig x spermatocytes (0.49); spermatocytes x Sertoli (0.49) and Sertoli x Leydig (0.96). The study demonstrates that the AgNOR staining technique is indicated to evaluate the cell proliferative potential in ovine testis with practical implementation and low cost.(AU)

ABSTRACT

Objetivou-se estudar a morfometria corpórea, as características do sêmen, o perfil proteico do plasma seminal em SDS-PAGE e a concentração sérica de testosterona em cervos-sambar (Cervus unicolor), criados em cativeiro, na estação reprodutiva da primavera. Quatro machos com idades entre 12 e 36 meses foram avaliados em quatro momentos, com intervalos de sete dias, com peso corpóreo (60,5 a 89,0kg), índice de massa corporal (93,07kg/m2 a 126,56kg/m2), volume do ejaculado (0,50±0,35mL a 0,75±0,28mL), motilidade espermática (87,75±4,78% a 90,00±7,07%), defeitos totais (17,25±5,81% a 47,72±17,55%), testosterona sérica (6,43±4,33ng/dL a 166,00±64,48ng/dL) e proteínas do plasma seminal com bandas entre 7,6 e 142kDa. As características dos ejaculados não diferiram (P>0,05) entre as três primeiras colheitas. Houve diferença (P<0,05) para os defeitos espermáticos com elevação na quarta colheita. No plasma seminal de cada cervo, foram identificadas de 16 a 27 bandas de proteínas entre 7,6 e 142kDa. Conclui-se que a qualidade espermática foi satisfatória na primavera. O estresse das contenções sucessivas causou queda da qualidade espermática. A idade influi na concentração sérica de testosterona, a qual foi maior nos cervos aos 36 meses...


The aim of this work was to study the body morphometry, semen characteristics, seminal plasma protein profile in SDS-PAGE and serum testosterone concentration in Sambar Deer (Cervus unicolor), in captivity in the breeding season (spring). Four males aged between 12 and 36 months were assessed in four moments with intervals of seven days with body weight (60.5 to 89.0kg), body mass index (93.07 to 126.56kg/m2), ejaculate volume (0.50±0.35mL to 0.75±0.28mL), sperm motility (87.75±4.78% to 90.00±7.07% ), total defects (17.25±5.81% to 47.72±17.55%), serum testosterone (6.43±4.33 ng/dL to 166.00±64.48ng/dL) and seminal plasma proteins with bands between 7.6 and 142 kDa. The characteristics of ejaculates did not differ (P>0.05) among ejaculates (1st, 2nd and 3rd). There were differences (P<0.05) for sperm defects elevation on the fourth ejaculate. In seminal plasma 16 to 27 protein bands between 7.6 and 142 kDa were identified. In conclusion, sperm quality was satisfactory in the spring and the stress of successive contentions decreased sperm quality. Also, there is influence of age upon serum testosterone concentration which was higher in deer at 36 months...

ABSTRACT

O objetivo deste estudo foi avaliar e comparar a eficácia de dois protocolos de tratamento de ceratoconjuntivite seca (CCS) experimentalmente induzida em coelhos: uma formulação oftálmica tópica composta por álcool polivinílico 1,4%, adicionado com acetilcisteína 10% e pilocarpina 1% (AAP), e outro protocolo com o uso do óleo de semente de linhaça (OL) tópico em forma de colírio, durante 12 semanas. Foram utilizados 15 coelhos machos, adultos, da raça Nova Zelândia, alocados aleatoriamente em três grupos: grupo C (controle), grupo AAP (formulação oftálmica) e grupo L (OL tópica). Os animais foram avaliados semanalmente pelo teste lacrimal de Schirmer, teste de fluoresceína e teste de Rosa Bengala; uma vez por mês, pelo exame de citologia esfoliativa ocular; ao final do experimento, pela análise histopatológica da córnea e conjuntiva. Os resultados demonstraram que houve um aumento maior na produção lacrimal quando utilizada a formulação oftálmica, e uma resolução mais rápida das úlceras de córnea, bem como diminuição no número de células desvitalizadas quando utilizado o óleo de semente de linhaça, além de aumento no número de células caliciformes em ambos os grupos de tratamento. A associação desses dois protocolos pode ser no futuro uma alternativa no tratamento da CCS.


The objective of this study was to evaluate and compare the effectiveness of two treatment protocol of experimentally induced keratoconjunctivitis sicca (KCS) in rabbits, a topical ophthalmic formulation composed by 1.4% povinilic alcohol added with 10% acetylcysteine and 1% pilocarpine (AAP) and another protocol with the topical use of the linseed seed oil (LO) in eye drop form f or 12 weeks. Fifteen male New Zealand white rabbits were aleatory allocated in 3 groups: Group C (Control), Group AAP (ophthalmic formulation) and Group L (LO topical). The animals were evaluated weekly using the Schirmer's tear test, fluorescein test and Rose Bengal test monthly for ocular cytology, and at the end of the experiment for histopathological analysis of cornea and conjunctive. The results demonstrated that there was a larger increase in the tear production when the ophthalmic formulation was us ed and a faster rapid resolution of corneal ulcers and decrease in the number of devitalized cells when linseed seed oil was used, besides an increase in the number of caliciform cells in both treatment groups. The association of those two protocols can be a future alternative in the treatment of KCS.

ABSTRACT

Relataram-se um surto de pododermatite e quadro septicêmico em aves de um canaril comercial. Quarenta e quatro canários de cor foram escolhidos de forma aleatória, sem distinção de sexo, idade ou cor, os quais vieram a óbito naturalmente, após terem sido afetados pela pododermatite, sem que tivessem se submetido a tratamento prévio. As aves mortas foram encaminhadas para o exame necroscópico, onde amostras de tecidos das áreas afetadas foram colhidas para exames microbiológico, micológico e histológico. Todas as aves necropsiadas apresentavam pododermatite, com inflamação em um ou mais dedos, de aspecto nodular, com ou sem presença de úlceras ou necrose. Staphylococcus aureus plasma coagulase positivo foi isolado dos pés e do fígado de todas as aves. Foi observado que todas as linhagens isoladas foram resistentes aos antimicrobianos da classe das penicilinas (penicilina G e ampicilina) e parcialmente sensíveis ou resistentes à ciprofloxacina. Apenas metade dos isolados foram sensíveis à neomicina e à estreptomicina. Problemas de saúde pública podem estar relacionados ao surgimento de animais reservatórios de cepas multirresistentes para seres humanos contactantes, como neste caso.


An outbreak of bumblefoot and septicemia was reported in birds of commercial breeding. Forty-four color canaries chosen at random, without regard to sex, age or color, which died naturally having been affected with pododermatitis and not undergoing any prior treatment were used. The dead birds were sent for necropsy in which tissue samples from affected areas were taken for microbiological, mycological and histological examination. All necropsied birds had bumblefoot, inflammation in one or more fingers, nodular, with or without the presence of ulcers and necrosis. Staphylococcus aureus plasma-coagulase positive was isolated from the liver and the feet of all birds. It was observed that all isolates were resistant to the penicillin class of antibiotics (penicillin G and ampicillin) and partially sensitive or resistant to ciprofloxacin. Only half of the isolates were sensitive to neomycin and streptomycin. Public health problems may be related to the emergence of animal reservoirs of multi-resistant strains for contacted humans, as in this case.
