The spread of influenza virus through a community typically causes large increases in medical visits for febrile respiratory disease. Increased school absenteeism occurs early in the epidemic, and school children appear to be important for disseminating the virus. Industrial absenteeism, hospitalizations of adults and infants for pneumonia, and deaths due to pneumonia-influenza all tend to peak later in the epidemic. Although influenza infection rates are highest in persons of school age, hospitalizations and deaths occur primarily in infants and in the elderly, particularly among those with pulmonary, cardiovascular, or other debilitating disorders. Influenza viruses can be spread by aerosol or contact. The primary target cells are those of the respiratory epithelium. In healthy adults, the typical influenza syndrome includes fever, cough, and general aches for three to seven days, but lassitude, cough, and evidence of small-airways disease may persist for weeks. Laryngotracheobronchitis, pneumonia, and unexplained fever are prominent manifestations of influenza that lead to hospitalization of young children. Adults are more likely to have complications of bacterial pneumonia and worsening of chronic pulmonary disease or congestive heart failure. Less frequent complications include myositis, various neurologic disorders, and Reye's syndrome. These consequences of influenza clearly justify strenuous efforts at prevention and control.

Twenty-three of 23 neonates were contaminated in the course of an outbreak of respiratory syncytial virus (RSV) in a neonatal care unit. Symptoms among 22 infected symptomatic infants included rhinitis (n = 21), dyspnea (n = 19), cough (n = 17), apnea (n = 5), seizures (n = 3), fever (n = 3). Five patients presented with severe respiratory distress. The occurrence of non-obstructive apnea was significantly correlated with a history of respiratory disease, RSV infection during the first 15 days of life and the severity of lower respiratory tract RSV infection.

An acute upper respiratory disease was observed in two broad-breasted white (BBW) turkey primary breeder flocks. Associated clinical signs included sneezing, depression, and a deep dry cough originating from large conducting airways. Morbidity reached approximately 15-20% of the hens in an affected house. None of the turkeys died, and total feed consumption was not affected. A minimal effect upon egg production was noticed. Sera from an acutely affected flock exhibited a marked rise in titer to Bordetella avium compared with preinfection sera samples. In Case 1, B. avium was isolated in pure culture from affected birds. In Case 2, B. avium was diagnosed by serological results and clinical signs; bacteriological examination was not attempted. The findings presented here are consistent with an acute clinical outbreak of B. avium-induced turkey rhinotracheitis (turkey coryza) in BBW turkey breeder hens.

Respiratory infections of 19 subjects of advanced age and/or with underlying respiratory disease were treated with cefoperazone (CPZ) and its clinical effects were studied. Sixteen subjects suffered from respiratory tract infection and 3 subjects had pneumonia. The age of the subjects ranged from 39 to 77 years with the mean of 63.8, 7 of them being more than 70 years of age. The underlying respiratory diseases included chronic pulmonary emphysema in 6 subjects, diffuse panbronchiolitis in 3, bronchiectasis in 3, silicosis in 2 and one each of chronic bronchitis, pulmonary fibrosis, lung cancer and old pulmonary tuberculosis. One case, 75 years of age, had renal insufficiency. The daily dose of CPZ was 4 grams in 18 of the 19 subjects and the duration of administration ranged 5 to 22 days. The remaining 1 subject received 2 g of CPZ daily for 6 days. Clinical effects were judged from the changes in fever, cough, amount of sputum, dyspnea, rales, cyanosis, chest X-ray, white blood cell counts, CRP, erythrocyte sedimentation rates and results of sputum culture. Clinical effects were good in 16 subjects, fair in 1, and poor in 2. Bacteriological follow-up was carried out in 13 subjects. Infecting bacteria were eliminated from 5 subjects, reduced in 2 and, in 4 subjects, they were replaced by other bacteria. In 1 subject, P. aeruginosa was isolated from sputum even after the treatment with CPZ, and in another subject H. influenzae relapsed immediately after the cessation of the CPZ treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Mycoplasma ovipneumoniae and Mycoplasma arginini were the species of Mollicutes most commonly isolated from 175 goats with respiratory disease in Ontario. The pathogenicity of M. ovipneumoniae, strain B321B and M. arginini, strain D53e, was assessed in goats following endobronchial inoculation. One out of three two year old goats developed fever after inoculation with a pure culture of strain B321B, and it had extensive subacute fibrinous pleuritis when necropsied three weeks later. Neither of the remaining goats had lesions in the respiratory tract. Mycoplasma ovipneumoniae was recovered from one of the animals four days after inoculation, but not at necropsy from any of the goats, at which time a marked humoral immune response with growth inhibiting antibodies was detected. In a second experiment three four to five week old goats were inoculated with the same strain and three other goats were given placebo treatment. One experimental goat developed fever and coughing, and it had extensive subacute fibrinous pleuritis in the right side and pneumonia. Another goat had focal pneumonia in the left diaphragmatic lobe. Microscopically there was subacute hyperplastic suppurative bronchiolitis, atelectasis and nonsuppurative alveolitis. The infected animals did not clear the mycoplasma and not all of them produced antibodies. Mycoplasma arginini, strain D53e, did not induce lesions in any of four goat kids within 14 days after inoculation but did cause transient elevations in rectal temperature, circulating monocytes, circulating neutrophils and blood fibrinogen. Mycoplasma arginini was infective and immunogenic for all inoculated animals and showed a particular affinity for the tonsil. Thus, this study provides the first evidence that M. ovipneumoniae is pathogenic for goats causing pneumonia and pleuritis.(ABSTRACT TRUNCATED AT 250 WORDS)

During a 10 year period 49 patients were recorded as having pulmonary infection caused by opportunist mycobacteria. Six different species were identified of which M. kansasii (65%) and M. avium-intracellulare (20%) were the most common. Cough and sputum (82%) or haemoptysis (26%) were frequent symptoms on presentation and over two thirds of patients had pre-existing respiratory disease. Chest radiographs showed predominantly apical disease with the right apex (44%) being twice as commonly affected as the left (22%). In 30% the radiograph showed bilateral disease. Clinicians had an individual approach to treatment with no uniform pattern of drug prescribing. A majority of patients (59%) received rifampicin for at least 9 months and those patients with M. kansasii infection responded well with no bacteriological relapses in 20 patients followed for a mean period of 3.9 years. M. avium-intracellulare, M. malmoense and M. xenopi were less responsive to treatment and in four patients receiving chemotherapy death was attributed to mycobacterial infection.

An illness among office workers, consisting of cough, fever, chills, muscle aches, and chest tightness was associated with water leaks from a cafeteria. Mean single breath carbon-monoxide diffusing capacity (DLCO) of cases differed significantly from that of non-cases. There was a significant decrease in the percent of predicted DLCO with increasing number of symptoms. Testing for precipitating antibodies to microbial agents found in the building revealed no differences between cases and non-cases. DLCO is an appropriate cross-sectional instrument for field investigations of building-associated respiratory disease.

Seventy-seven hospitalized children from whom respiratory syncytial virus was subsequently isolated were studied in retrospect. This demonstrated the association of host invasion by this agent with an acute respiratory disease requiring hospitalization for approximately one week.Boys considerably outnumbered girls, the average age was 7.5 months, and in 56% the admission diagnosis was "bronchiolitis". Cough and difficulty in breathing were the most common presenting complaints and "pneumonia" the most common radiological diagnosis. Nearly half the patients also harboured accepted disease-causing bacterial pathogens. All the patients recovered and have remained well.The appearance of the virus in Montreal was seasonal, beginning in late autumn and terminating in early spring.

A community study of respiratory disease on Karkar Island sampled 1734 people. Both sexes showed abnormalities, especially those over 35 years. 33% had a positive loose cough, 29% had adventitious sounds, and 11% had persistent cough. Smoking was universal by age 30. A local cigar made from the same type of tobacco (Brus) as commercial cigarettes (Nicotiana tobaccum) was the favorite smoke. Store bought cigarettes were used by 8% men, .8% women. 1.8% men and 12% women who smoked local tobacco inhaled, compared to 56% men who smoked commercial tobacco. Inhalers showed a higher frequency of symptoms than noninhalers. Nonsmokers had consistently higher values for lung function tests. However, differences in lung function were significant only in the FEV percentage in women. Wider use of commercial tobacco will likely increase inhalation leading to an increase in lung disease.

Thirty-five consecutive infants admitted into hospital in Newcastle upon Tyne with acute respiratory disease had cough/nasal swabs and nasopharyngeal secretions taken. Both types of specimens were examined by the fluorescent antibody technique for respiratory syncytial virus; isolation techniques were also used. Twenty-eight specimens of nasopharyngeal secretion were positive, as were 26 of the corresponding cough/nasal swab preparations. Respiratory syncytial virus was isolated from all but one.Sixteen consecutive children who were only suitable for examination by cough/nasal swab preparations were also investigated by isolation and fluorescent antibody techniques for respiratory syncytial virus. Respiratory syncytial virus was isolated from eight, seven of whom were positive by the fluorescent antibody technique. The use of cough/nasal swab preparations stained by the fluorescent antibody technique, although not as efficient as nasopharyngeal secretions, may have a place in the rapid diagnosis of respiratory virus infection in older children and children in general practice. The importance of rapid diagnosis for respiratory virus infection in relationship to antiviral therapy was also discussed.
