Channel catfish virus (CCV) disease is an acute haemorrhagic disease in juvenile channel catfish (Ictalurus punctatus). While fish that survive primary CCV infection are suspected of being carriers of CCV, little is known concerning CCV latency. In this report, fingerling catfish were infected with CCV by experimental immersion challenge. Infected fish displayed clinical signs of CCV disease, b...

A role for the aryl hydrocarbon receptor (AHR) pathway in vascular maturation has been implicated by studies in Ahr-null mice. In this study the hypothesis that activation of AHR signaling by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) alters common cardinal vein (CCV) development in the zebrafish embryo was investigated. The CCV is a paired vessel that grows across the yolk, connecting to the h...

Fecal secretory immunoglobulin A (IgA) antibodies in dogs infected or vaccinated with canine coronavirus (CCV) were evaluated by an enzyme-linked immunosorbent assay. The study was carried out with 32 fecal samples collected just before inoculation and at 28 days postinoculation. Five groups were studied: naturally infected dogs, experimentally infected dogs, dogs inoculated with a modified liv...

The purpose of this study was to investigate the genetic features of canine coronavirus (CCV) strains detected in Korea. M gene sequences obtained for isolates from 22 dogs with enteritis over a 5-year period were evaluated. Sequence comparison revealed that the 22 Korean CCV strains had an 87.2 to 100% nucleotide homology. Comparing to the typical reference CCV strains (type II), the nucleotid...

Canine coronavirus (CCV) is a single-stranded RNA virus belonging to the Coronaviridae family and is responsible for generally mild gastroenteritis in pups. Infected dogs shed CCV in feces for 6-9 days, but shedding can be prolonged in some pups. The virus content of feces is very high at the time of clinical signs. Electron microscopic (EM) examinations of fecal suspensions or isolation in tis...

Two giant pandas (Ailuropoda melanoleuca) died of unknown causes in a Chinese zoo. The clinical disease profile suggested that the pandas may have suffered a viral infection. Therefore, a series of detection including virus isolation, electron microscopy, cytobiological assay, serum neutralization and RT-PCR were used to identify the virus. It was determined that the isolated virus was a canine...

Canine coronavirus (CCV) and canine parvovirus type 2 (CPV-2) are the causative agents of gastroenteritis in dogs. Seventy fecal samples from dogs with signs of gastroenteritis (vomiting and diarrhea), twenty-five fecal samples from healthy dogs and one CPV-2 vaccine strain were amplified by semi-nested polymerase chain reaction (PCR) and semi-nested reverse transcriptase polymerase chain react...

Esta pesquisa revisita a aquisição das sílabas de ataque ramificado CCV (Consoante1+Consoante2+Vogal) em Português Brasileiro, investigando como o molde silábico é categorizado ao longo do desenvolvimento fonológico infantil e por que este ocorre da forma ocorre. Para caracterizar alvo sendo adquirido, um estudo corpus descreve variação CCV→CV presente na fala adultos paulistanos (como ‘outro’→...

UNLABELLED Coxiella burnetii replicates in an acidified lysosome-derived vacuole. Biogenesis of the Coxiella-containing vacuole (CCV) requires bacterial effector proteins delivered into host cells by the Dot/Icm secretion system. Genetic and cell biological analysis revealed that an effector protein called Cig2 promotes constitutive fusion of autophagosomes with the CCV to maintain this compart...
