M. pneumoniae is a common cause of pneumonia. The diagnosis is suspected when the patient presents with symptoms suggesting primary atypical pneumonia including cough, fever, chills, headache, and malaise in association with a segmental or subsegmental pulmonary infiltrate(s), the white blood cell count is normal or only slightly elevated, and the Gram stain of the sputum (if any can be obtained) reveals polymorphonuclear leukocytes and few bacteria. The diagnosis is more difficult when the patient presents with symptoms not suggestive of pneumonia including lethargy, dyspnea, and a 1- to 4-week history of shortness of breath without cough or fever in association with diffuse reticulonodular or interstitial pulmonary infiltrates. The disease in the previously healthy host is usually benign and self-limiting. However, the course is shortened by the administration of tetracycline derivatives or erythromycin. M. pneumoniae pneumonia can occur in association with other diseases including sickle cell anemia, sarcoidosis, systemic lupus erythematosus, Hodgkin's disease, and various other immunodeficiency states. In these patients mycoplasma pneumonia can be very serious. Although there is no pathognomonic clinical or radiographic presentation, careful consideration of epidemiologic, clinical, laboratory, and radiographic data are usually sufficient to suggest the diagnosis in most patients.

An outbreak of Mycoplasma pneumoniae infection occurred in the summer of 1978 in a boys' camp in northern Wisconsin and affected 139 of 196 persons (71%); 115 (59%) had laboratory evidence of infection. In 77% of the cases, onset of disease occurred within three weeks after arrival at camp, in contrast to the usually indolent spread of the disease. Attack rates decreased with increasing age. The sensitivity of serology for detecting M pneumoniae disease may have been as low as 79%. There was shorter duration of cough in those treated with erythromycin within four days after onset of symptoms.

Of approximately 200 members of a religious commune, 37 came to the emergency department of Cook County Hospital for primary medical care of respiratory illness. Of the 37, 31 were seen during a two-week period, indicating a rapid spread of disease. The major symptoms were cough, fever, coryza, and sore throat. Infiltrates were detected in 38%. Paired sera from four of nine patients showed a significant rise to Mycoplasma pneumoniae. Of 24 sera collected at the time of the first visit, 33% had a titer to the agent, of 64 or greater--presumptive evidence of Mycoplasma infection. Therefore, M pneumoniae was implicated as the causative agent in this outbreak of respiratory illness in a semi-closed community.

Mycoplasma mycoides subspecies mycoides (large-colony type) was isolated from the lungs of a goat with pneumonia. Clinical signs included inappetence, weakness, listlessness, coughing, dyspnea, pyrexia, slight nasal discharge, and lameness. Tylosin (4 mg/kg of body weight) was administered each day for 4 days, resulting in slow recovery. Three weeks later, the clinical signs recurred and the kid was anemic. It was given a single blood transfusion and tylosin was administered daily. The kid's health status was steadily declined and it died after 6 days' treatment. At necropsy, the lungs were edematous and congested. Histopathologic findings were those of septicemia and pneumonia.

Our understanding of chronic bronchitis has been hampered by the fact that the diagnosis is based upon historical evidence of recurrent cough and sputum without any requirement that certain physiologic or microscopic criteria be met. Despite the fact that epidemiological studies have implicated viruses, bacteria, and Mycoplasma pneumoniae in a varying percentage of exacerbations, in an individual case it is often difficult to establish a causal role for any agent. Antibiotics seem to reduce the morbidity of an infective exacerbation, but the widespread use of prophylactic antibiotics cannot be justified on the basis of the studies currently available. It would seem that the most sensible approach in the treatment of patients with chronic bronchitis would be to treat them on an individual basis, avoiding the indiscriminate use of antibiotics, but employing them on a trial basis in patients with a demonstrated proclivity for seasonal exacerbations. It is hoped that future clinical trials incorporating only patients meeting the classic criteria for chronic bronchitis and its exacerbations will develop treatments for this significant disease which are more successful than those currently available.

During the last twenty years pleuropneumonia in pigs, caused by Haemophilus pleuropneumoniae, has spread globally. The increasing importance of the disease within swine production is apparently connected with increasing industrialization and subsequent heavy concentration of a large number of animals in the individual production unit. Haemophilus pleuropneumoniae seems to be specific for pigs. Several more or less pathogenic serotypes of the bacterium are known. Serotype 2 as occurring in Denmark is primary pathogen for pigs which have not previously been in contact with the infection. Immunity of varying strength and duration is left after recovery. Prolonged immunity in an animal is presumably dependent on latent infection or on repeated infections. Normally there is a large number of latently infected animals in attacked herds. Such animals, especially sows and boars, represent a potential infection reservoir which might be the basis of new clinical outbreaks under conditions of reduced herd immunity or of compromised general resistance of animal groups. Clinical disease is most frequently seen in young pigs and fatteners, as piglets are generally protected by maternal antibodies. Acute pleuropneumonia is characterized by high temperature, lost appetite, light cough and often vomiting. Morbidity is high, especially by new-infection where there may also be considerable mortality if adequate antibacterial therapy is neglected, however, normally the disease implies low mortality. The pathological lesions are localized to the respiratory organs. The lungs are the seat of fibrinous necrotising pneumonia (red, grey hepatization), more or less extensive, most frequently of the diaphragmatic part of the lung. Furthermore fibrinous, later on fibrous pleuritis and pericarditis may be seen. The fibrous pleuritis may be of decisive diagnostical value when established with high frequency in baconers. The disease causes losses as a consequence of increased use of medicine and reduced daily weight gain in fatteners. Optimum environment and feeding conditions will reduce such losses considerably. The use of commercially available vaccines makes it possible to fortify specific resistance against the disease in exposed groups of animals. In small herds with few infected animals the infection may be eliminated by discarding seropositive animals, combined with strategic medication. Elimination of the infectious agent in large herds can only take place by replacing all animals by an SPF-herd.

Mycoplasma pneumonia usually follows a benign course and the patient does not require hospitalization. The present report summarizes the feature of eight children admitted for a moderately severe pneumonia during an epidemic of Mycoplasma pneumoniae in Victoria. All children were previously healthy. The usual presenting symptoms included cough, fever, lethargy, and weight loss. All children had moderately severe respiratory distress and physical signs in the chest consistent with extensive parenchymal involvement. Half of this group had radiological evidence of a small pleural effusion. Complement fixation titres for Mycoplasma pneumoniae in paired samples confirmed the diagnosis. Clinical and radiological resolution was complete after one to three months. It is suggested that severe mycoplasma pneumonia may be more common than previously appreciated.

The authors report the first two cases of legionnaires' disease from Catalonia. Both patients were chronic bronchitic males, and the cases were sporadic. The onset of the disease was characterized by a febrile illness with muscle and joint pains, respiratory symptoms (cough and mucous sputum production), and mental changes. There were no digestive complaints. Pulmonary consolidation occurred in both patients in the left upper lobe. Blood chemistries disclosed the existence of an absolute lymphopenia, altered liver function tests, and elevated CPK levels. Bacterial cultures of blood and sputum, respiratory virus screening (influenza A and B, parainfluenza 1, 2 and 3, and adenoviruses), and tests for Mycoplasma pneumoniae, Coxiella burnetti and Chlamydia psittaci were all negative. Antibody titers against Legionella pneumophila by indirect immunofluorescence were 1/1024 (positive) for serotype 1 and 1/1024 (positive) for serotype II in one patient, and 1/1024 (positive) for serotype I and 1/128 (negative) for serotype II in the other patient. The authors review the epidemiological, clinical, biochemical and diagnostic aspects of legionnaires' disease, which knowledge will undoubtedly allow to detect an increasing number of cases.

An acute pneumonia developed in 28 calves which had been housed together from one to two weeks of age. The clinical signs included pyrexia, tachypnoea, respiratory distress and coughing. Some of the calves died. The pneumonia was characterised by an alveolitis with multinucleated syncytia, alveolar epithelial hyperplasia and bronchiolitis. Interstitial emphysema was also present. Fifteen of 19 calves examined serologically had rising neutralising antibody titres to respiratory syncytial virus; in nine calves the rise was fourfold or greater. Respiratory syncytial virus was not isolated from the calves. There was no evidence of parainfluenza type 3 virus involvement. The adult cows being sucked by the calves remained clinically normal throughout the incident. Six calves examined six weeks after the outbreak started had a chronic cuffing pneumonia characterised by lymphocytic bronchiolitis; some of the calves also had bronchiolitis obliterans. Mycoplasma dispar was found in two of them.

Clinical effect of acetylspiramycin, one of macrolide antibiotics, primary atypical pneumonia and serologically proven Mycoplasma pneumonia in children was studied. Twenty-four cases of these pneumonia (PAP 11, MP 13) in children were selected and acetylspiramycin was given in dose of approximately 30 mg/kg/day orally. Clinical response was evaluated in terms of improvement in fever, cough and chest X-ray. Clinical response was excellent in 4, good in 5, fair in 14 cases and none in 1 case. No definite adverse effect was observed, however 3 cases showed skin rashes. Two cases showed evanescent small erythematopapulous rash and 1 case developed urticaria on the 2nd to 4th day after this drug was given. These skin rash seemed one of the manifestation of Mycoplasma infections, rather than adverse side effect. One case showed elevated transaminase activity before acetylspiramycin was given and improved on the 2nd week, although this drug was continued. No other side effect was observed. We were able to use acetylspiramycin only in the form of 200 mg tablet and difficulty of the administration was encountered in children under 5 years of age. Other form (dry syrup, etc.) of this drug should be considered for the clinical use in children. In conclusion, acetylspiramycin was effective and safe for the treatment of primary atypical pneumonia and Mycoplasma pneumonia.
