Diferentes amostras biológicas foram avaliadas (zaragatoa ocular, genital, urina e células mononucleares do sangue periférico) pela RT-PCR em 50 cães com sintomas neurológicos compatíveis como cinomose, na presença ou não de outros sintomas sistêmicos. O gene da nucleoproteína do vírus da cinomose foi detectado em 43 das 50 amostras avaliadas. Considerando apenas os animais com resultado positivos pela hemi-nested - PCR, os sintomas neurológicos observados com freqüência maior que 50%, foram mioclonia e alteração locomotora (maioria dos cães evoluiu a tetraparesia); convulsão e vocalização foram observados em 32% dos casos Outros sintomas sistêmicos, sintomas oculares, respiratórios ou digestivos, prévios ou associados aos sintomas neurológicos, foram observados em 82% dos cães. Também observou-se hiperqueratose nasal ou de coxins em 44% dos casos. Somente 20% dos animais positivos haviam sido vacinados contra o vírus da cinomose. Zaragatoas genitais forneceram maior número de resultados positivos (40), seguidos por zaragatoas oculares e urina (37) e células mononucleares do sangue periférico (34). A coleta associada de duas amostras biológicas (zaragatoa genital e urina) por animal aumentou a possibilidade de detecção de animais positivos...

Empregou-se a técnica de reação em cadeia pela polimerase precedida de transcrição reversa para detecção do vírus da cinomose canina (CC). Para a padronização da técnica foram selecionados quatro pares de oligonucleotídeos (P1, P2, N1, H1), baseados em seqüências dos genes da fosfoproteína, neuraminidase e hemaglutinina, sendo utilizadas três cepas vacinais de vírus da CC como controles positivos. Foram analisadas três amostras isoladas de cães com cinomose e quatro amostras provenientes de cães com suspeita clínica de cinomose. Não houve amplificação nas amostras com suspeita clínica da doença. Os resultados obtidos com os oligonucleotídeos P1 e N1 foram superiores aos de H1. Os oligonucleotídeos P2 foram considerados inapropriados para a detecção do vírus da CC. Os amplicons obtidos com os oligonucleotídeos P1, N1 e H1 foram clivados com endonucleases de restrição, sendo os perfis das amostras virais comparados aos da amostra vacinal Lederle, utilizada como referência. Um padrão similar de restrição foi observado em todas as amostras analisadas.; The reverse transcription-polymerase chain reaction was used to detect canine distemper virus (CDV). Four oligonucleotide pairs were selected (P1, P2...

Doenças infecciosas em animais selvagens têm aumentado devido às alterações em seu habitat e ao maior contato com animais domésticos. A cinomose já foi descrita em diversas espécies de carnívoros selvagens, representando uma ameaça à conservação da vida selvagem. Nesse estudo é descrito o primeiro caso de infecção pelo vírus da cinomose em um furão (Galictis cuja). Um indivíduo de vida livre, sem sinais clínicos aparentes, apresentou morte súbita após um dia em cativeiro. Foi realizado o diagnóstico molecular para detecção do vírus da cinomose canina, sendo o resultado positivo. A filogenia do vírus indicou que cães domésticos foram a provável fonte de infecção.; Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals.

Canine distemper virus (CDV) may induce multifocal demyelination in the central nervous system of infected dogs. The present work investigated apoptosis in white and gray matter (granular layer) in the cerebellum of naturally infected dogs by the analysis of the expression of the pro-apoptotic antigens caspase - 2 and - 3, b(terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL-staining) positivity, annexin-V immunodetection, and the presence of the anti-apoptotic antigens, BCl-2 and p53. Cerebellum specimens were obtained from the Laboratory of Animal Pathology, from 1995 to 2009, and the 5-μm thick fragments were stained both with hematoxylin-eosin and Shorr. All samples were diagnosed as positive for CDV genome by reverse transcriptase polymerase chain reaction targeting the nucleocapsid gene. The anti-apoptotic pathways evidenced in this study were BCl-2 and p53 proteins that were intensively detected in cerebellum of CDV positive slides (40-80% of labeled cells/mm2). In addition, the apoptosis markers annexin-V and TUNEL are directly correlated among the same samples (80 and 40% of labeled cells, respectively). This is the first description of p53 and annexin-V expression, characterized as anti-apoptotic and apoptotic proteins...

Distemper leukoencephalitis is a disease caused by the canine distemper virus (CDV) infection. It is a demyelinating disease affecting mainly the white matter of the cerebellum and areas adjacent to the fourth ventricle; the enzymes of the matrix metalloproteinases (MMPs) group, especially MMP-2 and MMP-9 have a key role in the myelin basic protein fragmentation and in demyelination, as well as in leukocyte traffic into the nervous milieu. To evaluate the involvement of MMPs during subacute distemper leukoencephalitis, we measured the levels of MMP-2 and MMP-9 by zymography in the cerebrospinal fluid (CSF) and in the cerebellum of 14 dogs naturally infected with CDV and 10 uninfected dogs. The infected dogs presented high levels of pro-MMP-2 in the CSF and elevated levels of pro-MMP-2 and pro-MMP-9 in the cerebellar tissue. Active MMP-2 was detected in the CSF of some infected dogs. As active MMP-2 and MMP-9 are required for cellular migration across the blood-brain barrier and any interference between MMPs and their inhibitors may result in an amplification of demyelination, this study gives additional support to the involvement of MMPs during subacute distemper leukoencephalitis and suggests that MMP-2 and MMP-9 may take part in the brain inflammatory changes of this disease. © 2013 Elsevier B.V.

Canine distemper virus (CDV) is a viral disease that affects dogs and many other carnivores. Clinical diagnosis of CDV is difficult due to the broad spectrum of signs that may be confounded with other respiratory and enteric diseases of dogs. Laboratory analysis is required to diagnose suspected cases. In this study, surface plasmon resonance (SPR) and electrochemical impedance spectroscopy (EIS) methodologies were developed for the detection of canine distemper virus simultaneously. The assay exhibited high specificity, as all the negative controls were not mistakenly detected. The CDV concentration was determined from successive injections into the apparatus, with a linear range from 1.1 to 116.0 ng mL-1. The system exhibited good reproducibility with 4.5% variation between runs after regeneration of the coated surface with a solution of 0.1 M glycine-HCL (pH 3.0). The capacitance and resistance values of the modified interface were calculated from EIS data using an equivalent circuit. It was possible to measure CDV in highly concentrated viruses with good specificity and reproducibility. © 2013 The Royal Society of Chemistry.

A quantitative real time polymerase chain reaction (PCR) revealed canine distemper virus presence in peripheral blood samples from asymptomatic and non vaccinated dogs. Samples from eleven domestic dogs with no signs of canine distemper and not vaccinated at the month of collection were used. Canine distemper virus vaccine samples in VERO cells were used as positive controls. RNA was isolated with Trizol®, and treated with a TURBO DNA-free kit. Primers were designed for canine distemper virus nucleocapsid protein coding region fragment amplification (84 bp). Canine b-actin (93 bp) was utilized as the endogenous control for normalization. Quantitative results of real time PCR generated by ABI Prism 7000 SDS Software showed that 54.5% of dogs with asymptomatic canine distemper were positive for canine distemper virus. Dissociation curves confirmed the specificity of the real time PCR fragments. This technique could detect even a few copies of viral RNA and identificate subclinically infected dogs providing accurate diagnosis of this disease at an early stage.

The thymic morphometry analysis was used for determining apoptosis and atrophy of the thymus of eight puppies inoculated with canine distemper virus (CDV). Three healthy dogs were used as negative controls. Sections, 5µm thick, were stained by HE and Shorr, and the latter were evaluated by morphometry. CDV nucleoprotein was detected by immunohistochemistry. Morphometric results confirmed lymphoid hypotrophy in CDV inoculated dog thymuses, more stroma, less parenchyma and higher apoptotic index/field than negative control (not inoculated) puppies. Apoptosis plays a role in the mechanism of thymus atrophy that develops in canine distemper.

Eleven central-nervous-system samples collected from stray dogs between 2000 and 2004 were found positive by RT-PCR, which amplified a 480bp fragment of the N gene of canine distemper virus (CDV). Phylogenetic analysis based on partial N-gene sequences showed four major clusters. All dog strains segregated into cluster I, with a mean nucleotide identity of 95.8% and 95.6% with the Onderstepoort and Lederle vaccine strains, respectively. Cluster II contained all the raccoon-related strains, cluster III Orient strains and Cluster IV the Onderstepoort and Lederle vaccine strains, with a mean nucleotide identity of 99.7% between them. This is the first report of phylogenetic analysis of CDV strains in Brazil.

A review of the number of dogs submitted for necropsy at the Department of Veterinary Pathology of the Federal University of Santa Maria, RS, between 1985-1997 has shown that 11.7% (250/2136) had lesions and inclusion bodies characteristic of infection by canine distemper virus (CDV). Most of these cases occurred during the winter months in dogs that were less than 1.5 year old, which were submitted by residents from the city of Santa Maria. Canine distemper is considered endemic in this city. Significant differences in susceptibility were not observed between males and females. Mongrel dogs were super-represented, but dolichocephalic breeds were more affected than brachycephalic ones. Distemper encephalopathy with typical CDV inclusion bodies, especially in astrocytes, was the main lesion and occurred in 82% of these cases. Eosinophilic inclusion bodies characteristic of canine distemper were also observed in epithelial cells of the urinary bladder (15%), lung (6%), stomach (3%), kidney (1%), and tonsil (0.5%).

A case of multifocal distemper encephalomyelitis in a mature dog is described. In the presented case the ante mortem clinical diagnosis of canine distemper virus (CDV) infection could not be ideally performed due to the absence of typical signs of distemper, such as myoclonus and systemic signs accompanying the nervous signs. The definitive diagnosis of distemper encephalomyelitis was only carried out at post mortem through virus isolation in cell culture from fresh central nervous system (CNS) fragments and CDV nucleoprotein gene detection in the CNS by RT-PCR.

Infections by free-living amoebae can cause systemic disease in animals and humans. We describe the epidemiological, clinical and pathological aspects of disseminated acanthamoebiasis associated with canine distemper in three dogs of the semiarid region of Paraíba, Northeastern Brazil. Affected dogs developed progressive neurological and respiratory signs that progressed to death within in two to 20 days. Gross lesions were irregular and with yellow-reddish nodules randomly distributed in the lungs, heart, kidneys, spleen, lymph nodes, adrenals, and intestine. One dog had foci of malacia in the parietal cortex and another one in nucleus of brain basis. Histologically, pyogranulomas with areas of necrosis and hemorrhage in all organs affected were observed, associated with myriads of intralesional amoebic trophozoites. All three cases were concomitant canine distemper, that possibly triggered immunosuppression in the dogs. The diagnosis was performed through microscopic findings of infection by free-living amoebae and confirmed Acanthamoeba sp. by immunohistochemistry

A cinomose canina (CC) é uma doença viral sistêmica de carnívoros, cujo diagnóstico é embasado em sinais neurológicos e extra-neurais. A desmielinização que ocorre nesta doença assemelha-se à das doenças desmielinizantes humanas, o que a torna um modelo animal para estudo de doenças neurodegenerativas humanas. Lesões iniciais do SNC caracterizam-se por desmielinização sem considerável inflamação e lesões tardias por um processo inflamatório crônico. Vários métodos são empregados para o diagnóstico da CC, destacando-se a RT-PCR como precisa e sensível. Estudar, prospectivamente, os achados clínicos e histopatológicos do cérebro de 49 cães com cinomose diagnosticada clinicamente, e confrontá-los com os resultados da RT-PCR foi o nosso objetivo. A presença de sinais neurológicos foi significante para o diagnóstico da doença, especialmente a mioclonia e ataxia. O comprometimento inflamatório era significante no cerebelo, hipocampo e diencéfalo sendo que a reação inflamatória era maior no diencéfalo. Quanto maior o peso cerebral, menor era a desmielinização. Nos animais na fase clínica aguda, a freqüência de desmielinização cerebelar foi maior. Foi significante a localização linização...

The exposure of 13 Brazilian free-ranging nondomestic canids (five pampas fox - Pseudalopex gymnocercus and eight crab-eating fox -Cerdocyon thous) from Southern region of Brazil, to Canine distemper virus (CDV), canine parvovirus (CPV) and Canine coronavirus (CCoV) was investigated. Antibodies against CDV were detected in 38.5% (5/13) of the samples. There were anti-CDV antibodies in 60% (3/5) of P. gymnocercus and in 25% (2/8) of C. thous. The frequency was higher among the adults and males. Eleven canids (84.6%) presented antibodies against CPV, 80% (4/5) were from P. gymnocercus and 87.5% (7/8) were from C. thous. There was no difference in positivity rate against CPV between gender and age. Antibodies against CCoV were detected in 38.5% (5/13) of the samples, with 60% (3/5) of positivity in P. gymnocercus and 25% (2/8) in C. thous. The frequency of antibodies against CCoV was higher among the adults and males. The study showed that these canids were exposed to CDV, CPV and CCoV.

To help understand why there is a prevalence of canine distemper in Brazil, we interviewed 404 owners of dogs that were in clinics or veterinary hospitals about distemper. Our results showed that 80.4% of respondents knew about distemper and 67.6% knew that it is a severe and fatal disease. Approximately 50.9% knew that distemper can be prevented by the use of the vaccine, but 60.9% did not know about distemper vaccines. Our results show that the lack of knowledge and, consequently, the lack of vaccination against distemper may be the most important factors in the endemic presence of distemper in Brazil.
