Diagnosis of cardiac lesions by contrast echocardiography.

Contrast M-mode echocardiography was utilized to study animals with congenital and acquired cardiac defects. Contrast was produced through the rapid injection of isotonic NaCl solution, the patient's blood, or indocyanine green dye into the circulation. Peripheral vein and intracardiac injections of contrast material were used to document ventricular septal defect, tetralogy of Fallot, atrial septal defect, and mitral valve regurgitation. The technique was safe and useful for both small and large animals.

Generalized parvovirus disease in neonatal pups.

Generalized canine parvovirus disease was diagnosed in a litter of pups that died when 3 to 9 days old. Parvovirus was isolated from the heart, lungs, liver, kidneys, and small intestine. Histologically, lesions were characterized by hemorrhage and necrosis in the brain, liver, lungs, kidneys, lymphoid tissues, and gastrointestinal mucosa. Intranuclear inclusions were found in vascular endothelium, heart, lungs, liver, kidneys, adrenal cortex, and gastrointestinal tract.

Comparative susceptibility of a canine cell line and bluetongue virus susceptible cell lines to a bluetongue virus isolate pathogenic for dogs.

Recently, bluetongue virus (BLU) serotype 11 was detected in diseased dogs that had been inoculated with live attenuated vaccine contaminated with this serotype of bluetongue virus (Akita et al., 1994). For various laboratory tests, BLU can be propagated in different cell cultures. No information was found in the literature about the possibility of propagating this virus in canine cells. To determine whether the BLU isolate from the contaminated canine vaccine (BLU-vac) is unique in its ability to replicate in canine cells, this virus was studied in parallel with U.S. prototype strains of BLU (serotypes 2, 10, 11, 13, and 17), in hamster lung (HmLu-1) and canine kidney (MDCK) cell cultures. In HmLu-1 cell cultures, the BLU-vac produced cytopathic effect (CPE) of the same type as the U.S. prototype BLU strains by 4 to 6 d postinoculation. In MDCK cell cultures, all of the BLU strains tested were able to replicate but did not produce CPE. The BLU-inoculated MDCK cells became persistently infected, and these cultures continued to produce infectious BLU even after six serial passages over 2 1/2 mo. In none of these cultures was CPE observed. In mixed cultures containing both HmLu-1 and MDCK cells, CPE first affected the HmLu-1 islands; subsequently, CPE spread also to the areas with MDCK cells. The silent persistent infection of the MDCK cells with BLU indicates that more stringent screening of the cells used in the production of live vaccines for various contaminating viruses is necessary.

Cystic echinococcosis in the Americas.

Echinococcus granulosus and related genotypic variants, the agents of cystic hydatid disease, occur widely in the American continents from Alaska and Northern Canada in North America to Tierra del Fuego in South America. Here we review the historical and current distribution and prevalence of these infections throughout the American countries and the results of programs to control or eliminate the infection.
