13. Emergence of rifampin-resistant Rhodococcus equi in an infected foal.
To investigate the emergence of rifampin resistance in Rhodococcus equi strains isolated from foals and their environment in Japan, we compared the in vitro antimicrobial susceptibilities to rifampin of 640 isolates from 64 infected foals and 98 soil isolates from their horse-breeding farms. As a control, 39 human isolates from patients with and without AIDS

14. Atrial septal defect of the persistent ostium primum type with hypoplastic right ventricle in a Welsh pony foal.
Valvular competency of the foramen ovale (patent foramen ovale) is regarded as a common finding in the neonatal foal and usually occurs in isolation. True atrial septal defects appear to be uncommon and are usually associated with other congenital cardiac lesions. The present report describes a case of atrial septal defect type 1 (persistent ostium primum) c

15. Hypogammaglobulinemia and Thymic Hypoplasia in Horses: a Primary Combined Immunodeficiency Disorder
A severe combined immunodeficiency disorder was demonstrated in two Arabian foals which were full siblings. The defect in the B-lymphocyte system was shown by hypogammaglobulinemia, lymphopenia, and absence of germinal centers. The almost total absence of thymic tissue in one foal and the lack of thymic dependent lymphocytes in the spleens of both foals demo

18. Passive transfer of mucosal antibody to Streptococcus equi in the foal.
Passive transfer of mucosal antibody to Streptococcus equi was studied in foals during the first 2 months of life. Immunoglobulin G (IgG) and IgA antibodies were found in sera and nasal secretions of foals shortly after colostrum intake. Titers were highest 2 days after birth; IgG predominated in sera, and IgA predominated in nasal washes. Intragastrically a

19. Immunoglobulin and specific antibody responses to Rhodococcus (Corynebacterium) equi infection in foals as measured by enzyme-linked immunosorbent assay.
Humoral immune response to intestinal Rhodococcus (Corynebacterium) equi in horses was studied by enzyme-linked immunosorbent assay. Anti-R. equi immunoglobulin M (IgM), IgG, and IgA antibodies were demonstrated in the healthy horse population. Adult horse levels of anti-R. equi IgM and IgG antibodies were reached by 5 to 9 weeks of age in two healthy newbor

21. Unusual vascular ring anomaly in a foal
A 2.5-month-old filly was presented with signs of esophageal obstruction. The filly was euthanized and postmortem examination revealed a vascular ring anomaly. The vascular ring anomaly was not caused by a persistent right aortic arch, which is the only vascular ring anomaly reported to occur in horses.

22. Thyroid hyperplasia and musculoskeletal deformity in a standardbred filly in Ontario
Thyroid hyperplasia and musculoskeletal deformity, described in foals in western Canada, has not been recognized as a common cause of neonatal foal mortality in Ontario. A case is reported from Ontario, with clinical and histopathological findings consistent with the syndrome described in western Canada.

23. Protein-losing enteropathy caused by Lawsonia intracellularis in a weanling foal
A 5-month-old Morgan filly was presented to the Atlantic Veterinary College with a history of lethargy, fever, depression, anorexia, and dependent ventral edema. Diagnostic tests revealed severe inflammation, hypoproteinemia, and thickened small intestinal loops. Protein-losing enteropathy caused by Lawsonia intracellularis was diagnosed and treated successf

24. Characterization of a Coronavirus Isolated from a Diarrheic Foal
A coronavirus was isolated from feces of a diarrheic foal and serially propagated in human rectal adenocarcinoma (HRT-18) cells. Antigenic and genomic characterizations of the virus (isolate NC99) were based on serological comparison with other avian and mammalian coronaviruses and sequence analysis of the nucleocapsid (N) protein gene.
