The experiment was designed to study the effect of a heavy antibiotic dose on fecal microflora during the 33-d treatment period as well as its effects upon the intestinal wall. Conventional adult mice received either a casein-starch diet (conventional controls) or an antibiotic-supplemented (0.66% dry matter, DM) diet (treated conventionals); Furthermore, germ-free (axenic) mice taken from isolators to the open animal room received the same antibiotic-supplemented diet (treated axenics) Fecal microbial population remained around 10(8)/g in the conventional mice while it decreased to 10(3)/g in the treated conventional mice. Fecal microbial population of the treated axenic mice dropped to 10(2)/g. At the end of the 33-d treatment period, no significant difference in ileal villus height between the treated or control groups no difference either was seen in the aspects of the villus and cell surface as shown by scanning electron microscopy. In the control group, however, development of bacterial colonies exhibiting various shapes were observed on the intestinal mucus. Although it was found that antibiotic treatment was followed by significant changes in microbial population and biochemical composition of digestive contents, this study concluded that the structure of the distal ileal epithelium was not impaired.","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.

A fragment located in a constant area of the viral genome was biotin-labelled. This probe, when present at a concentration of 100 ng/ml of the hybridization solution, could detect 10 pg of target DNA immobilized on nitrocellulose with cellular DNA and RNA. The virus was evidenced after being passaged on monkey kidney cells, either 8 h post-inoculation (pi) if the multiplicity of infection (MOI) was at least 1 hemadsorbing unit (HAd) per cell, or 24 h later if the inoculum was diluted up to 10(-3) HAd per cell. When passaged on pig leukocytes with a MOI of 0.1 HAd per cell, the virus was evidenced 12 h pi, or 24 h pi with a MOI of 10(-2) HAd per cell. The probe did not hybridize with another DNA virus passaged on cells, neither did it react with non-infected blood or ham, but did so if African swine fever virus was resuspended with the samples. The spleen from uninfected pig and the lymph nodes from a pig which had died from hog cholera were found to be negative, whereas the spleen from a pig which had died of African swine fever was positive. These samples were also tested with a 32P-labelled probe whose sensitivity was 10-fold higher. A non-radioactive probe could be used both for the sensitive and specific diagnosis of African swine fever and the detection of the virus in an epidemiological survey.","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.

There is little information about the pathogenesis of this infection. Attachment of microorganisms to eucaryotic cells is considered to be a prerequisite for colonization of the host in the pathogenesis of bacterial infections. Forty-seven P multocida strains isolated from pigs in France, and belonging to capsular type A or D were tested for their ability to agglutinate human erythrocytes, and to adhere to tracheal and lung cells. Each isolate was tested for dermonecrotic toxin production. Adherent strains were further observed by electron microscopy to look for attachment structure. Only type A strains agglutinated human O erythrocytes, but no relationship was observed between hemagglutination and dermonecrotic toxin production. The results of the adherence tests showed a greater affinity (P less than 0.05) of type A strains for lung cells (50% were adherent, whereas only 20% of type D strains were adherent) but did not reveal any correlation between adherence and the presence of dermonecrotic toxin. Microscope observations showed that these P multocida strains did not possess any pili-like structures. In conclusion, by means of the adherence test we were able to demonstrate a stronger adherence of type A strains and this adherence did not seem to be related to pili-like structures.","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.
