In specific pathogen-free dogs, clinical signs of experimental canine parvovirus infection were mild, inconsistent and transient. Clinical signs were more pronounced in conventionally-raised dogs, but the severe disease reported in field cases was not reproduced in either group. A pronounced plasma viremia occurred on the 2nd to 4th day post-infection (d.p.i.) in dogs challenged oronasally. Antibody was detectable on the 5th d.p.i. Marked pyrexia was rare, but a significant temperature rise usually coincided with the appearance of antibody and the cessation of viremia. Significant lymphopenia, but not leukopenia, occurred on the 3rd to 7th d.p.i. Virus could be readily isolated from fecal matter on the 3rd to 8th d.p.i.; a few dogs continued to shed virus for up to 12 days. In dogs challenged parenterally, the onset of elevated temperatures, viral shed and antibody production occurred 24-48 hours sooner. Convalescent dogs were no longer contagious for susceptible contact animals 25 days or longer after challenge, although infectious virus persisted in feces for more than 6 months at room temperature. Active giardiasis seemed to exacerbate the clinical syndrome, although treatment with corticosteroids or anti-thymocyte serum did not.

Primary immunodeficiencies (PIDs) are a relatively common occurrence in countries where consanguineous marriages are widespread. A principal factor leading to misdiagnosis and ensuing complications can be the lack of knowledge and proper evaluation. The aim of this study was to assess PID awareness and the identification of diagnostic criteria leading to correct diagnosis. Seven hundred eighty-six questionnaires with 71 items were distributed to physicians attending the 41st National Congress of Pediatrics (2005) and to pediatric residents of two university hospitals from different cities in Turkey. The 217 completed questionnaires revealed that family history (91.2%), consanguineous marriages (87.1%), infant deaths (70.0%), persistent thrush (90.3%), hospitalization for recurrent cellulitis (70.5%), chronic diarrhea due to giardiasis (62.2%), recurrent oral aphthous lesions (58.5%), telangiectasia (82.0%), failure to thrive (78.8%), absence of tonsil tissue (74.7%), oculocutaneous albinism (73.7%), and resistant sinusitis (71.0%) were cited among important indicators of PID. However, neonatal tetany (77.9%), liver abscess (61.3%) and poliomyelitis following oral polio vaccination (51.2%) were not considered as related to PID. Although white blood cell (WBC) and differential were chosen as the preferred initial tests, leukocytosis and lymphopenia were also not judged as related to PID. More comprehensive pre/postgraduate education in PID appears to be necessary for physicians in Turkey.
