Radiography, CT, and MRI Diagnosis of Enzootic Nasal Tumor in Goats Infected With Enzootic Nasal Tumor Virus.

The aim of this study was to describe radiography, computed tomography (CT), and magnetic resonance imaging (MRI) findings of enzootic nasal tumors in goats infected with enzootic nasal tumor viruses. Five of six goats with a mean age of 2 years, showed clinical signs of respiratory disease. Head radiographs showed increased density of the unilateral or bilateral nasal cavity in four goats, and a CT scan showed that the space-occupying lesion of the nasal cavity originated from the ethmoid bone and was enhanced homogeneously postcontrast in all goats.

Is Downregulated and Prone to Microsatellite Instability on ABCC9tetra in Canine Breast Cancer.

Tumorigenesis is associated with metabolic abnormalities and genomic instability. Microsatellite mutations, including microsatellite instability (MSI) and loss of heterozygosity (LOH), are associated with the functional impairment of some tumor-related genes. To investigate the role of MSI and LOH in sporadic breast tumors in canines, 22 tumors DNA samples and their adjacent normal tissues were evaluated using polyacrylamide gel electrophoresis and silver staining for 58 microsatellites.

Microsatellite Instability and MMR Genes Abnormalities in Canine Mammary Gland Tumors.

Early diagnosis of mammary gland tumors is a challenging task in animals, especially in unspayed dogs. Hence, this study investigated the role of microsatellite instability (MSI), MMR gene mRNA transcript levels and SNPs of MMR genes in canine mammary gland tumors (CMT). A total of 77 microsatellite (MS) markers in 23 primary CMT were selected from four breeds of dogs.

Sequence analysis of the thrombospondin-related adhesive protein gene and heat shock protein 70 gene of Babesia gibsoni isolated from dogs in Nanjing, China.

In this study, the thrombospondin-related adhesive protein (TRAP) gene and the heat shock protein 70 (Hsp70) gene of Babesia gibsoni isolated from the naturally infected dog in the Nanjing area were cloned and sequenced. Twenty blood samples were collected from the suspected cases of babesiosis at the animal hospital of Nanjing Agriculture University. Genomic DNA was extracted from the blood samples, and the 18S rDNAs were amplified by PCR to confirm Babesia infection.

Copper-modified palygorskite is effective in preventing and treating diarrhea caused by Salmonella typhimurium.

The aim of this research was to develop effective alternative therapies to reduce antibiotic use in animal agriculture. In this study, the efficacy of copper-modified palygorskite (CM-Pal) in preventing diarrhea caused by Salmonella was specifically examined both in vitro and in vivo. The CM-Pal was prepared with palygorskite (Pal) and copper nitrate.

Altered expression of the mismatch repair genes in DF-1 cells infected with the avian leukosis virus subgroup A.

The absence or deficiency of DNA mismatch repair (MMR) activity results in microsatellite instability (MSI) in cancer. The avian leukosis virus (ALV) causes neoplastic disease in chickens. In this study, the status of MMR, MSI, the cell cycle and apoptosis were detected in DF-1 cells after avian leukosis virus subgroup A infection.

Canine Babesiosis in China Caused by Babesia gibsoni: A Molecular Approach.

Background: To provide a point of reference to study the epidemiology and clinical expression of canine babesiosis in China.

Methods: A total of 30 dogs infected with canine babesiosis were evaluated by mean of clinical history, physical examination, hematological, restriction fragment length polymorphism of PCR products (PCR-RFLP) and sequencing analysis.

Result: The most prevalent clinical abnormalities were lethargy (100%), anorexia (100%), pale or icteric mucous membranes (80%), fever (70%) and dark urine (70%).

Microsatellite instability in chicken lymphoma induced by gallid herpesvirus 2.

Microsatellite instability (MSI) has been found in a range of human tumors, and little is known of the links between MSI and herpesvirus. In order to investigate the relationship between MSI and Gallid herpesvirus 2 (GaHV-2)-induced lymphoma, fifteen Marek's disease (MD) lymphomas were analyzed through using 46 microsatellite markers, which were amplified by PCR from DNA specimens of lymphoma and normal muscular tissues from the same chicken. PCR products were evaluated by denaturing polyacrylamide gel electrophoresis for MSI analysis.
