The development of a specimen collection and transport medium outfit for the rapid laboratory diagnosis of whoping cough is described. The transport medium consisted of a semisolid agar containing charcoal, cephalexin, and defibrinated horse blood. It was also found to be an excellent enrichment medium for the selective isolation of Bordetella pertussis and B. parapertussis from scantily populated specimens. The investigation of 3,237 specimens that yielded 1,419 positive isolates of Bordetella, including 86 B. parapertussis, during a 20-month period is presented. A total of 3,076 specimens were processed in the laboratory by using the enrichment medium in addition to the routine procedure. Of these specimens, 757 were submitted in our medium, from which 137 (18%) were positive. Of the 567 specimens received in Amies transport medium, 290 (51%) positive cultures were obtained by the enrichment method only and not by primary culture.

Several infectious agents are involved in the kennel cough complex in dogs. They include canine parainfluenza virus (SV5), canine adenovirus 2, Bordetella bronchiseptica, and possibly several mycoplasma species. The importance of each of these agents in the disease syndrome is discussed as well as possible prevention or treatment.

A detailed study of a population of dogs with kennel cough was undertaken. Twenty-seven (77 per cent) of a total of 35 dogs had pathological evidence of respiratory disease in the form of tracheobronchitis with, in some animals, exudative pneumonia. A variety of viral and bacterial agents were isolated from the respiratory tract of diseased dogs but Bordetella bronchiseptica and canine parainfluenza virus SV-5 appeared to be the most significant organisms recovered.

Cultures of Bordetella pertussis were isolated by pernasal swabs from Kenyan children in whom whooping-cough was suspected. Serotyping of 94 of these isolates was undertaken by four laboratories in Europe, and there was very close agreement in their typing results. Each laboratory found that the incidence of type 1, 3 was the lowest of the three types, and that there were approximately equal numbers of types 1, 2, 3 and 1, 2. No new serotype was found. This distribution of serotypes was found in all age-groups; and it is in marked contrast with that currently seen in vaccinated communities, where type 1, 3 predominates. The implications of these findings for vaccination against whooping-cough in East Africa are discussed.

A five week old male infant is treated under suspicion of whooping cough because of pertussis like cough, cyanosis, and attacks of reflex apnea. These attacks are seen up to 40 times per day. After exclusion of a cerebral genesis there was found a ventral indentation of the trachea. It was also seen by tracheoscopy, but this part of the trachea was not pulsating. In the angiography the compriming structure was identified as the innominate artery. The genesis of this anatomic variant, the often threatening symptoms in this case without inspiratoric stridor, and the diagnostic and therapeutic steps are discussed.

Eight collie-cross pups, eight weeks old, were inoculated intramuscularly with an aluminum hydroxide adjuvanted preparation of killed Bordetella bronchiseptica; the inoculation was repeated after two weeks. Two weeks after the second inoculation, the vaccinated dogs and a control group of four unvaccinated animals were placed in contact with a group of five pups of similar age which had been experimentally infected with a pathogenic strain of B bronchiseptica by an aerosol method. All four unvaccinated control dogs as well as all five experimentally infected dogs developed a respiratory disease characterised by persistent coughing. Six of the vaccinated dogs remained free from clinical respiratory disease while disease was less severe and of shorter duration in the remaining two than in controls. Only slight changes were found in the lungs of vaccinated animals at necropsy while in the controls there was a severe tracheobronchitis. There was a marked reduction in the numbers of B bronchiseptica isolated from the respiratory tract of vaccinated animals when compared with controls. An aluminium hydroxide adjuvanted vaccine may be of value in controlling naturally occurring canine respiratory disease in which B bronchiseptica is involved.

A group of eight-week-old dogs was inoculated with a heat-killed suspension of Bordetella bronchiseptica by the intramuscular route on two occasions at an interval of two weeks. All vaccinated animals developed high circulating agglutinin titres by two weeks after the second inoculation at which time the vaccinated dogs and a comparable group of unvaccinated animals were challenged by exposure to an aerosol of live B bronchiseptica. Both vaccinated and unvaccinated dogs subsequently developed clinical respiratory disease characterised by persistent coughing but the onset of disease in vaccinated animals was delayed by up to five days when compared with the controls. B bronchiseptica was isolated from the nasal cavity, tracheobronchial tree and lung parenchyma of vaccinated and control dogs.

Six collie dogs, eight weeks old, were inoculated intramuscularly with an aluminium hydroxide adjuvanted preparation of killed Bordetella bronchiseptica; the inoculation was repeated after two weeks. Two weeks after the second inoculation, the vaccinated dogs and a comparable group of six unvaccinated animals were challenged by exposure to an aerosol of pathogenic B bronchiseptica. All six unvaccinated control dogs developed respiratory disease characterised by persistent coughing. In contrast, four of the vaccinated dogs remained free from clinical respiratory disease while, in the other two dogs, disease was less severe and of shorter duration than in controls. At necropsy, there were only slight changes in the lungs of vaccinated dogs but in controls there was a severe tracheobronchitis with areas of exudative pneumonia. Bacteriological examination showed a marked reduction in the numbers of B bronchiseptica isolated from the respiratory tract of vaccinated animals compared with controls. An aluminium hydroxide adjuvant vaccine may be of value in controlling naturally occurring respiratory disease in dogs in which B bronchiseptica is involved.

The role of Bordetella bronchiseptica as a primary pathogen in nautrally occurring respiratory disease of dogs has been in question since its original isolation in 1911. A study to determine the incidence of B. bronchiseptica in a closed breeding kennel has revealed that the frequency of such isolations is closely associated with mild respiratory disease characterized by a moist, sometimes productive, cough. Infection with B. bronchiseptica usually occurred shortly after weaning and produced illness which lasted for one to two weeks. The organisms, however, continued to be shed for two to three months, and important factor in maintaining the infection in this kennel. Adult dogs sampled at frequent intervals did not harbor B. bronchiseptica in spite of their almost constant exposure to heavily infected pups; immunity to reinfection, therefore, appeared to develop. The involvement of several known canine respiratory viral agents was excluded by virus isolation and serological techniques. It therefore was concluded that B. bronchiseptica was the primary cause of respiratory disease in this large breeding kennel.

The progeny of 9 SPF gilts fed a balanced ration (Table I) was used in an inoculation experiment with field strains of Bordetella bronchiseptica isolated in herds suffering atrophic rhinitis. Acute rhinitis was produced within a week after intranasal inoculation of B. bronchiseptica into 1 to 11-day-old piglets. Coughing occurred in some of the exposed pigs, but signs of pneumonia did not develop. A few pigs were killed at intervals of 1 to 3 weeks after exposure. These pigs all showed histological lesions in the turbinate and B. bronchiseptica was recovered from various parts of the respiratory tract. Pigs killed 3 weeks after inoculation showed advanced turbinate atrophy (Tables II and III). Among inoculated litter mates reared to slaughter weight, only one developed clinical signs (slight) of atrophic rhinitis, and a tendency towards an elimination of the B. bronchiseptica infection from the accessible part of the nasal cavity was noticed during the growth period. By examination of nasal swabs collected when the pigs were 10 to 13 weeks old, Mycoplasma flocculare was isolated as well from pigs inoculated with B. bronchiseptica as from the control pigs. The growth rate of the experimental pigs was high and no difference in feed consumption or feed conversion occurred between the exposed pigs and the control pigs. By post mortem examination of the snouts from the pigs slaughtered at approx. 85 kg live weight, severe atrophic rhinitis was not found. Approximately one third (32%) of the exposed pigs showed slight atrophic rhinitis lesions (Table IV). The results are discussed and it is concluded that the isolated B. bronchiseptica strains are pathogenic in young pigs and able to induce turbinate atrophy 2 to 3 weeks after inoculation. Turbinate atrophy induced in pigs a few weeks old, may apparently restore completely or almost completely during the growth period. Under the provided experimental conditions, infection with B. bronchiseptica did not result in the development of a lasting, growth-retarding atrophic rhinitis.
