Intranasal infection with Bordetella bronchiseptica in gnotobiotic piglets.

Nineteen gnotobiotic piglets, four to six days old, from three different litters, were inoculated intranasally on three consecutive days with a pure culture of Bordetella bronchiseptica. Necropsy 10 to 30 days after inoculation revealed atrophic rhinitis lesions in all and pneumonia in 13 (73 per cent)infected piglets. One died of septicaemia two days after inoculation. Agglutinating antibodies were detected in the sera of all piglets necropsied from 17 to 30 days after inoculation. Five control piglets showed no lesions or serological changes.

Feline infectious peritonitis. Proteins of plasma and ascitic fluid.

Electrophoreses of sera, plasma and ascitic fluids of cats with natural or experimental infectious peritonitis show important modifications. Special stainings of electrophoreses and chromatographic and immunoelectrophoretic technics characterized some of the modified proteins. In the experimental disease, fibrinogen, haptoglobin, transferrin, and probably orosomucoid are increased; in the natural disease, in addition to these modifications, the gamma-globulins are strongly increased; the immunoglobulins found in the often abundant ascitic fluid belong to the IgG class. Increased proteins such as fibrinogen, haptoglobin and orosomucoid and decreased albumin are aspecific aspects of inflammatory processes, whereas hypergammaglobulinemia appears in the course of immunological response. The rapid evolution of the experimental disease explains the fact that immunoglobulins do not increase.

[Herpes virus isolated from pigeons (author's transl)].

A virus has been isolated from pigeons with the clinical symptoms of "infectious coryza". The virus produces numerous pocks on the chorio-allantoic membranes; livers from infected embryos have areas of necrosis. Microscopic examinations reveals basophilic and eosinophilic intranuclear inclusions. The virus produces a cytopathic effect of rounded refractile cells after 24 h with rapidly spreads throughout the monolayer. The virus is sensitive to chloroform. Electron microscopy of negatively stained lysed cell preparations shows that the virus is a herpesvirus. The strain is pathogenic for pigeons. Lesions produced by intralaryngeal inoculation consists of small necrotic foci in the laryngeal epithelium and in the liver.

Analysis of foodborne disease in Belgium in 1997.

Foodborne disease represents a major problem for public health in industrialized countries, albeit with a low lethality. Foodborne diseases are defined as a group of viral, bacterial or parasitic gastrointestinal infections transmitted by means of food. Proper food-hygiene practices and surveillance of individual diseases and in particular outbreaks are the first steps in targeting their prevention. The incidence of this illness is difficult to estimate. In the Netherlands a yearly incidence of gastrointestinal infections of 500 per 1,000 inhabitants is estimated, of which most are foodborne. To set up priorities in the actions to undertake, to establish the most frequent risks, to develop preventive efforts and to answer to international requirements, accurate data on foodborne disease from Belgium are required. In order to co-ordinate the initiatives in the Belgian context, a working group was set up in 1995. In 1997 a total of 2,013 persons with foodborne disease were identified as part of 140 outbreaks, 22 of which occurred with 10 cases or more. Salmonella Enteritidis (88 outbreaks) was identified as the main pathogen in foodborne disease, followed by S. Typhimurium (11), S. Hadar (4). Eggs and meat products were identified as the main food-items involved, although it remains difficult to obtain proper intervention studies allowing to identify the specific cause(s). In 1997, a total of 12,732 human Salmonella isolates and 5,617 Campylobacter isolates were identified by the respective national reference laboratories. Salmonella isolates from Belgium accounted in 1997 for more than a fifth of all Salmonella isolates in the EU. The final objective of the working group is the implementation of a surveillance system for all risk factors concerned with the development of food-related illness, including an early warning system and an efficient analysis of microbiological criteria relating to human health, food and food production, including livestock. An essential element of this surveillance is communication of the results, risks and measures for prevention between all the departments, institutions and public health authorities concerned.
