1. Detection of respiratory viruses in shelter dogs maintained under varying environmental conditions
Abstract Three dog shelters in Rio Grande do Sul were investigated for associations between the occurrence of respiratory viruses and shelter environmental conditions. Nasal secretions randomly collected during the cold season were tested via PCR, and this data collection was followed by nucleotide sequencing of the amplicons. In shelter #1 (poor sanitary an

2. Anticorpos neutralizantes contra os vírus da cinomose e da parainfluenza em cães de canis dos municípios de Novo Hamburgo e Porto Alegre, RS, Brasil / Neutralizing antibodies to distemper and parainfluenza viruses in dogs in shelter kennels in the municipalities of Novo Hamburgo and Porto Alegre, RS, Brazil
No presente estudo, foi realizada uma pesquisa em busca de anticorpos neutralizantes contra os vírus da cinomose (CDV) e da parainfluenza (CPIV) caninos em amostras de soro de 173 cães recolhidos a canis municipais em Novo Hamburgo (n=82) e Porto Alegre (n=91), RS. A pesquisa de anticorpos neutralizantes foi realizada pela técnica de soroneutralização f

3. Anticorpos neutralizantes contra os vírus da cinomose e parainfluenza caninos em cães e felinos silvestres em cativeiro. / Neutralizing antibodies to distemper and parainfluenza viruses in dogs and captive wild felids
O vírus da cinomose canina (CDV) e o vírus parainfluenza canino (CPIV) afetam uma ampla variedade de hospedeiros e encontram-se distribuídos mundialmente. O CDV é considerado um dos mais importantes agentes infecciosos dentro das populações caninas. Este vírus é o agente causal da cinomose, uma doença potencialmente letal em membros das famílias Ca

4. Comparison of different tissue cultures for isolation and quantitation of influenza and parainfluenza viruses.
Rhesus and cynomolgus monkey kidney tissue cultures and two continuous lines, Madin-Darby canine kidney (MDCK) and LLC-MK2, were compared in titrations and isolations of influenza and parainfluenza viruses. Tube cultures were inoculated with laboratory virus strains or stored patient specimens and observed for hemadsorption. Trypsin was added to the medium o

5. Longitudinal Study of Viruses Associated with Canine Infectious Respiratory Disease
In this investigation a population of dogs at a rehoming center was monitored over a period of 2 years. Despite regular vaccination of incoming dogs against distemper, canine adenovirus type 2 (CAV-2), and canine parainfluenza virus (CPIV), respiratory disease was endemic. Tissue samples from the respiratory tract as well as paired serum samples were collect

6. In Vitro Identification and Characterization of a Virus Isolated from a Dog with Neurological Dysfunction
A virus, 78-238, isolated from the cerebrospinal fluid of a dog with neurological dysfunction, was characterized as a paramyxovirus. This conclusion was supported by viral cytopathic effects and morphological appearance of virions and nucleocapsids in infected cells. Nucleocapsids were found in the cytoplasm of all infected cells and in the nuclei of 0.001%

7. Microneutralization test for influenza A and B and parainfluenza 1 and 2 viruses that uses continuous cell lines and fresh serum enhancement.
A modified microneutralization test for influenza A and B and parainfluenza 1 and 2 viruses was developed. Use of continuous cell lines (Madin-Darby canine kidney and LLC-MK2), hemagglutination for virus detection, and transfer plates and other microtiter equipment resulted in a highly mechanized technique suitable for titrating large numbers of sera easily

8. Simian Virus 5 Is a Poor Inducer of Chemokine Secretion from Human Lung Epithelial Cells: Identification of Viral Mutants That Activate Interleukin-8 Secretion by Distinct Mechanisms
We have compared chemokine secretion from human lung A549 cells infected with simian virus 5 (SV5) with other members of the Rubulavirus genus of paramyxoviruses. High levels of the chemokines interleukin-8 (IL-8) and macrophage chemoattractant protein-1 (MCP-1) were secreted from A549 cells infected with Human parainfluenza virus type 2 (HPIV-2) but not fro

9. Intracellular neutralization of influenza virus by immunoglobulin A anti-hemagglutinin monoclonal antibodies.
Traditionally, immunoglobulin A (IgA) was thought to neutralize virus by forming complexes with viral attachment proteins, blocking attachment of virions to host epithelial cells. Recently we have proposed an intracellular action for dimeric IgA, which is actively transported through epithelial cells by the polymeric immunoglobulin receptor (pIgR), in that i
