An outbreak of Bordetella bronchiseptica pneumonia occurred in a breeding colony of common marmosets (Callithrix jacchus). 16 animals, all except one under 12 months of age, died suddenly. Extensive lesions of pneumonia and pleurisy were found at necropsy and B. bronchiseptica was isolated from the nasopharynx, trachea and lungs. Older animals had only a mild rhinitis. Colonization of the nasal mucosa occurred in 71 of 156 marmosets.

A rural development project carried out in Southern Zimbabwe for 5 years was aimed at improving nutrition, combatting diseases, educating villagers about proper hygiene, improving water quality, and assessing the development and nutritional status of children under 5. The community investigated consisted of 10,000 people or 1,439 families with an average of 7 persons per family. The main staple of their diet was maize, and malnutrition was prevalent. Water holes infested with bilharzia were the source of drinking water for both man and animal. The project succeeded in vaccinating 90% of preschool children against whooping cough, diphtheria, tetanus, polio, measles, and tuberculosis. A control district was chosen to compare the developmental data obtained by the Cole Slide Rule Calculator of 229 children under 5 with those of 242 children in the project. Malnutrition was studied in 200 children hospitalized in the children's ward of a district hospital, 1/3 of whom were less than 1 year old. Gastroenteritis, giardiasis and amebiasis were prevalent among them (37%), as were upper respiratory infections (27%), pneumonia (12%), and skin infections (7%). Nonspecific gastroenteritis was found in 86% of children under 2. Most over 2 were severely undernourished. A nutritional rehabilitation village called Hutano Village was established in 1982 to function as a nutritional center, staffed by a full-time health worker and an assistant. In the 1st 9 months of its existence, 114 children were taken in, and the mothers received instruction in vegetable gardening, raising chickens and rabbits, hygiene, and family planning. The average attendance runs to 25 children and 15 to 17 mothers. In spite of successful medical intervention in malnutrition cases, the relapse of children into an undernourished state remains a difficult issue, whose cause lies in inadequate water supply, poor soil, lack of resources, and low family socio-economic status.

The immunogenicity and safety of an attenuated Bordetella bronchiseptica vaccine for swine atrophic rhinitis (AR) was evaluated in 22 hysterectomy-produced, colostrum-deprived pigs and 18 conventional pigs. None of 8 pigs inoculated at 7 days of age intranasally with greater than or equal to 3 X 10(5) colony-forming units (CFU) of vaccinal strain/pig and 2 of 5 pigs inoculated at 7 days of age intranasally with 3 X 10(4) CFU of the vaccinal strain/pig developed AR after intranasal challenge exposure with a virulent strain at postinoculation week (PIW) 3. The remaining 3 vaccinated pigs and 4 nonvaccinated pigs developed AR. Thirteen pigs were inoculated intranasally with 3 X 10(6) to 3 X 10(9) CFU of the vaccinal strain at 7 days of age. At PIW 12, the pigs were killed and necropsied. None of the pigs had clinical signs of AR and/or pneumonia. Virulence was studied by transmission of vaccinal strain through 3 serial growing passages on the nasal mucosa of a litter of hysterectomy-produced colostrum-deprived pigs. Inoculum (nasal swab samples from 2 pigs 4 days after inoculation with 10(8) CFU of vaccinal strain at 5 days of age) was inoculated into the nasal cavity of 2 nonvaccinated pigs. This procedure was repeated 3 times. After the 1st passage, the vaccinal strain was recovered on postinoculation day 4, but after postinoculation day 4, the vaccinal strain was not recovered until the end of the 3rd passage. Turbinate atrophy or pneumonia was not recognized in these inoculated pigs. The vaccinal strain provided immunogenicity without ill effects.

Pneumonia and atrophic rhinitis were studied for the second consecutive year in pigs at the same test station. Pneumonia was found to reduce mean daily gain by 3.3% for every 10% of the pig's lungs that had lesions. Atrophic rhinitis did not affect mean daily gain. There was no association between the development of atrophic rhinitis and the development of pneumonia. Pigs that were vaccinated with a Bordetella bronchiseptica bacterin did not have turbinate atrophy scores or mean daily gains different from those in pigs that were not vaccinated. Yorkshire and Hampshire pigs had higher prevalences and severity of pneumonia and atrophic rhinitis, compared with pigs of other breeds.

An epidemiological study of atrophic rhinitis was carried out in four pig herds. Observations were made of (i) infection with Bordetella bronchiseptica and Pasteurella multocida, (ii) the presence of brachygnathia superior (BS score), (iii) the extent (grade) of turbinate atrophy and pneumonia at slaughter and (iv) growth rates from two to 16 weeks of age and average daily weight gains to slaughter. In two of the herds with no history of atrophic rhinitis, B bronchiseptica and non-toxigenic strains of P multocida were isolated; only one of 47 pigs (2 per cent) had a BS score greater than +10 mm and the most severe turbinate atrophy observed in 21 pigs at slaughter was grade 3. In contrast, from two herds with atrophic rhinitis, toxigenic strains of P multocida were isolated as well as B bronchiseptica and non-toxigenic P multocida. BS scores of greater than +10 mm were present in six of 47 pigs (13 per cent) of which five were infected with toxigenic P multocida and had severe turbinate atrophy of grade 4 or 5. There was no significant reduction in growth rates in the affected compared with the unaffected herds nor in the affected compared with the unaffected pigs in the same herd. Neither was there a correlation between progressive disease and the extent of pneumonia found at slaughter. It was concluded that in field cases of the disease, high BS scores plus severe turbinate atrophy were associated with infection by toxigenic type-D strains of P multocida.

Mice immunized with a killed vaccine of phase I Bordetella bronchiseptica were challenged with various numbers of virulent B. bronchiseptica by intraperitoneal, intracerebral, or intranasal routes. The course of infection was compared among these routes, and the protective effect of vaccination was quantitatively analyzed. In ddN mice infected intraperitoneally with 1.8 X 10(8) cells (ca. 80 times the 50% lethal dose [LD50]) the organisms rapidly increased in the intraperitoneal fluid, spleen, and liver within few days and caused splenic atrophy, septicemia, and death. However, immunizations with 5 X 10(9) cells gave the mice a high agglutinin titer and suppressed the increase in the number of organisms. With four immunizations, the lungs and livers were clear within 3 days, and with one or two immunizations, they were clear within 7 days. These immunizations effectively protected the mice from death but did not protect them from splenic atrophy. In the intracerebral infection with 1.4 X 10(6) cells (ca. 1.2 X 10(5) LD50), the number of organisms rapidly increased in the brain and caused encephalitis, splenic atrophy, and death. However, four or five immunizations completely suppressed the increase in the brain and protected the mice from death and splenic atrophy. After intranasal infection with 4 X 10(6) cells (ca. 25 LD50), the organisms rapidly increased in the nasal cavity and lungs and caused pneumonia and death. Immunization with 5 X 10(9) cells was effective in clearing the organisms from the lungs and in protecting against death and splenic atrophy. However, the organisms were not cleared from the nasal cavity for 60 to 150 days after the challenge with as little as 10(2) cells, even in the mice with an agglutinin titer as high as 1:10,000.

9, 3"-Diacetylmidecamycin (MOM), a new macrolide antibiotic, was administered to 28 patients: 6 with pharyngitis caused by Group A beta-Streptococcus, 2 with lacunar tonsillitis, 8 with upper respiratory tract infection, 6 with acute bronchitis, 3 with Mycoplasma pneumonia, 1 with primary atypical pneumonia, 1 with pneumonia caused by H. influenzae and 1 with whooping cough. MOM in the form of fine granules was administered at a daily dose of about 20-30 mg/kg divided into 3 doses. Isolated group A beta-Streptococcus strains were eradicated in only 1 out of 6 strain S. One strain of H. influenzae was eradicated. The clinical results could be obtained with 21 cases and the response was excellent in 1 case, good in 7, fair in 3 and poor in 10. Although diarrhea was found in 3 cases during the administration of MOM, it was not clear whether these phenomena were caused by MOM, because of the prevalence of diarrhea among the children treated by us at that time.

A total of 62 gnotobiotic pigs were inoculated with Bordetella bronchiseptica at 7 days of age. There were 25 noninoculated controls. Thirteen of the inoculated pigs were killed and 6 pigs which died were examined between 3 and 5 weeks after inoculations were done (group A). Of these 19 pigs, 16 had severe pneumonia and B bronchiseptica was isolated from the lungs of 17. The turbinates in most of the pigs appeared to have some atrophy. Four other pigs died of pneumonia after they were transferred to the floor in isolation rooms, and 9 inoculated pigs were examined at necropsy at about 112 days of age (group B). Bordetella bronchiseptica was isolated from 8 of the latter 9 pigs, and 7 of the pigs had pneumonic lesions. The turbinates all appeared normal. Thirty inoculated pigs (group C) were killed at 180 days of age. Of these, 22 had pneumonic lesions. Bordetella bronchiseptica was reisolated from the turbinates of 2 of 30 pigs, although the turbinates in all appeared normal. The noninoculated controls examined at necropsy at 3 to 5 weeks, 112 days, and 180 days of age did not have any pulmonic lesions, and their turbinates appeared normal. The inoculated pigs killed at 112 days of age gained an average of 0.25 kg/day, and the control pigs gained 0.31 kg. At 180 days of age, the inoculated pigs had gained 0.41 kg/day and the controls, 0.49 kg. Bordetella bronchiseptica infection in susceptible pigs can cause a severe pneumonia which can persist and reduce the growth rate.

An adult, male guinea pig died of Bordetella bronchiseptica pneumonia during quarantine and was necropsied, Numerous, firm, pale nodules were found attached to the omentum, the parietal peritoneum, and the serosal surface of the liver and intestinal tract. Gross, light, and electron microscopic examination revealed the tumors to be mesotheliomas. To our knowledge, mesotheliomas have not been reported in this species.

Three types of lesion were present in the lungs of guineapigs with chronic pneumonia - pulmonary interstitial fibrosis, perivascular lymphoid hyperplasia and foreign body granulomas. Bordetella bronchiseptica was present in the nasopharynx, trachea and lungs of a high proportion of animals from 4 weeks old, and antibodies to this organism were also found. Animals removed at 4 days old and reared in isolation from the main colony and free from B. bronchiseptica developed similar lung lesions, so that B. bronchiseptica appeared to have no causative role in these forms of chronic pneumonia.
