A new antigenic variant of swine influenza virus was isolated from the lungs of pigs experiencing respiratory problems in 7 different swine herds in Quebec. Pigs of different ages were affected, and the main clinical signs were fever, dyspnea, and abdominal respiration. Coughing was not a constant finding of the syndrome. At necropsy, macroscopic lesions included the overall appearance of pale animals, general lymphadenopathy, hepatic congestion, and consolidation of the lungs. Histopathologic findings were mainly proliferative pneumonia with a significant macrophage invasion, necrotic inflammatory cells in the alveoli and the airways, a marked proliferation of type II pneumocytes, and thickening of the alveolar septae. Fluorescent antibody examination of lungs of sick piglets did not demonstrate porcine parvovirus, transmissible gastroenteritis virus, or encephalomyocarditis virus. However, evidence of the presence of an influenza type A infection was demonstrated by indirect immunofluorescence (IIF) staining using monoclonal antibody directed to nucleocapsid protein (NP) of human type A influenza virus. The virus was isolated either by intra-allantoic inoculation of specific-pathogen-free embryonating hens' eggs or propagation in canine kidney (MDCK) cells in the presence of trypsin. By hemagglutination inhibition tests, no cross-reactivity was demonstrated with human influenza H1N1, H2N2, and H3N2 strains, and infected MDCK cells did not react by IIF with monoclonal antibodies to NP protein of type B influenza virus. The hemagglutination activity of plaque-purified isolates was only partly inhibited by hyperimmune serum produced to subtypes A/Wisconsin/76/H1N1 and A/New Jersey/76/H1N1 of swine influenza virus. Gnotobiotic piglets that were infected intranasally with egg-adapted isolates of this new antigenic variant of swine influenza virus developed the very same type of lesions observed in field cases.

During the last 40 years vaccines have been developed that have greatly reduced the incidence of infectious diseases of dogs. In general, modified live products have been superior to inactivated vaccines for dogs. It can be expected that recombinant and/or DNA vaccines may dominate the market in the future. Although most vaccines on the market are safe and efficacious, there have been exceptions where disease was induced by vaccination or dogs were not protected. The failure of protection may in part be due to variations in individual vaccine batches. Only potency tests but not efficacy tests are required, which may not be sufficient. For example, a virus titer in a vaccine may be meaningless if the minimum protective dose is not known. Overattenuated virus (e.g., CDV-Ond or parvovirus in cat cells) may have a high titer in tissue culture but is not immunogenic. The question of frequency of vaccination of dogs should be addressed. Annual revaccinations for CDV, CPV, and CAV are probably not needed. However, it would be desirable to collect more data to support less frequent vaccinations. Annual immunization for bacterial diseases such as kennel cough, Lyme disease, and leptospirosis should continue. It also would be desirable to develop more oro/nasal vaccines, perhaps combined with newly developed vectors that are less likely to induce undesirable side effects that may be seen after parenteral vaccination. Finally a word of warning against homeopathic "nosodes" to replace tested canine vaccines. They will appear highly effective as long as the majority of dogs remain vaccinated. As soon as a nonvaccinated dog population is large enough to allow virulent agents to spread, disease outbreaks will occur and we will be back where we began 40 years ago.

The prevalence of diseases suffered by dogs within two weeks of their acquisition from a rescue shelter in Northern Ireland was investigated. A postal questionnaire was completed by 556 people who had purchased a dog from the Ulster Society for the Prevention of Cruelty to Animals (USPCA) to provide information on the diseases suffered by their dog. The majority of the dogs (53.7 per cent) had an ailment the most common being coughing and diarrhoea. Of the respondents who returned their dog to the USPCA, 92 per cent did so because the animal was unhealthy. Stray dogs were more likely to have an ailment than unwanted dogs, specifically coughing, and/or skin problems. More puppies suffered from parvovirus, vomiting, and/or diarrhoea than did juveniles or adults. Adult dogs were more likely to have a cough than juveniles or puppies. There was no association between the sex of the dogs and their ailments.

A 22-year-old Caucasian woman with a 6 year history of persistently active, systemic onset juvenile rheumatoid arthritis (JRA) developed symptoms of headache, dry cough, nausea, vomiting, abdominal pain, diarrhea, and dehydration associated with a high fever, elevated liver enzymes, and lymphopenia. Subsequent investigation revealed acute infection with parvovirus B19. Following clinical improvement over 10-14 days solely with supportive care, her underlying disease remained in remission for about 7 months.

A 10-year-old girl was admitted with a 3-day history of fever, cough, abdominal pain and vomiting. Severe neutropenia (total neutrophil count 186/mm3), a mild increase in ALT and AST, and a positive titer of IgM antibodies against parvovirus B19 were found. The neutropenia resolved and liver enzymes became normal as she recovered. We conclude that parvovirus B19 infection should be considered in the evaluation of an acute illness accompanied by severe neutropenia.

A decline in T-cell-mediated immunity and transient state of immunosuppression after immunization has been reported in dogs. Nevertheless, dogs are still routinely vaccinated with polyvalent live vaccines and severe disease does not generally occur. In order to investigate these effects on the canine immune system and to elucidate possible mechanisms we determined the following immune parameters in the blood of 33 clinically sound German shepherd dogs before and after standard vaccination with a polyvalent vaccine against distemper, parvovirus, viral hepatitis, leptospirosis, kennel cough and rabies: white and differential blood cell count, the serum concentrations and/or activities of IL-1, IL-2, IFN-gamma, TNF-alpha, neopterin and IgG, natural killer (NK) cell activity, bactericidal activity and complement hemolytic activity, lymphocyte proliferation test (LPT) and nitroblue tetrazolium test (NBT). Our major findings were that significant postvaccinal decreases in T-cell mitogenic response to PHA and in neutrophil function and neopterin serum concentration were accompanied by simultaneous increase in plasma IgG and hemolytic complement activity. This suggests a transient shift in the balance between cell-mediated and humoral (T(H)1/T(H)2) immunity rather than immunosuppression. These results do not imply that dogs should not receive live vaccines, as the response to vaccines just seems to create a state of altered homeostasis when immunization elicits protection by humoral and cell-mediated immunity. However, these recognized compromises of immune function should be considered and vaccines still be applied only in healthy animals and strictly according to the rules and regulations given by the manufacturer.

A 6-month-old male golden retriever was presented with fever, bloody-watery diarrhea and mild cough. Parvovirus and Isospora canis infection was confirmed and successfully treated. Two weeks later, the dog had severe cough and mucopurulent nasal discharge. Aspergillus niger was cultured from endotracheal washings on blood agar at 37 degrees C. Treatment with itraconazole for about 10 weeks resolved the clinical signs.

A male patient aged 67 years with chronic renal failure (CRF), who had undergone hemodialysis since June 3, complained of dyspnea while walking on June 23, 1998. Rapidly progressive anemia and severe reticulocytopenia were noted. Serological tests showed that parvovirus B19- (B19) specific IgM antibody, but not IgG antibody, was present in the patient's serum. B19 DNA was detected in the patient's serum by the polymerase chain reaction (PCR). Therefore, a definite diagnosis of transient aplastic crisis induced by B19 was made. On June 10, prior to the appearance of this case, a female nurse aged 27 years working in our hemodialysis center, complained of cough, fever and arthralgia. Another female nurse, aged 35 years, developed similar symptoms on July 3. Both nurses had a positive IgM titer against B19, but were negative for IgG, indicating an acute B19 infection. These findings led us to suspect that this series of B19 infection was spread by nosocomial transmission. Although some cases of B19 infection have been reported to occur in laboratory staffs, the B19 nosocomial infection has not been described in the literature. We also suggest that a transient aplastic crisis due to B19 infection could lead to severe anemia in cases of CRF whose erythropoiesis is maintained by a recombinant human erythropoietin.

A new human parvovirus, human bocavirus, has recently been identified in respiratory secretions, feces and serum. It is associated with lower and most likely also upper respiratory tract infections. Most commonly reported symptoms are cough, rhinorrhea, expiratory wheezing and fever, and the virus is preferentially detected in young children. We report three children with acute lymphoblastic leukemia who had acute febrile episodes with concomitant detection of human bocavirus in their respiratory secretions. One of them had five consecutive febrile episodes during 6 months, all associated with the presence of human bocavirus at varying viral loads, suggesting prolonged shedding or reactivation of the virus.
