We performed transtracheal aspiration (TTA) in 1165 patients, who were suspected to have bronchopulmonary infection, from December 1978 to March 1993. We isolated pathogens from TTA in 806 patients (69.2%). We isolated H. influenzae (62 cases), S. pneumoniae (39 cases) and M. catarrhalis (24 cases) in patients with acute bronchitis, S. pneumoniae (65 cases), alpha-Streptococcus sp. (52 cases), H. influenzae (32 cases) and S. aureus (29 cases) in patients with pneumonia or lung abscess and H. influenzae (174 cases), S. pneumoniae (84 cases), P. aeruginosa (81 cases) and M. catarrhalis (42 cases) in patients with chronic lower respiratory tract infection. Anaerobic bacteria isolated from TTA included Peptostreptococcus sp. (19 cases), Bacteroides sp. (19 cases) and others. Mycoplasma pneumoniae was isolated from TTA in 8 patients with pneumonia without other organisms. Virus isolated from TTA included Rhinovirus (6 cases) and others. These results suggest that various pathogens affect the pathogenesis of bronchopulmonary infection. Therefore, we must diagnose the bronchopulmonary infection by the correct methods such as TTA.

Among 72 adult patients with a diagnosis of acute bronchitis, serological investigation established the presence of an aetiologic agent in 29 (40%). Influenza virus was the most common pathogen. Seven patients had bacterial infection, caused by pneumococci in four patients and Mycoplasma pneumoniae in three. Five of the patients had pneumonia as diagnosed by radiography, and mycoplasmal aetiology was established in one of these. Altogether, 11 patients either had bacterial infection or radiographic pneumonia. Although the doctors' recording of wheezes was strongly associated with prescription of antibiotics (p < 0.0001), wheezes were heard only in two of the 11 patients with pneumonia or bacterial infection, compared with 30 of the 61 patients with viral or unspecified bronchitis. The median value of C-reactive protein (CRP) was 52 mg/l in the 11 patients, significantly higher than < 11 mg/l in the 61 other patients (p < 0.0001). The corresponding values for erythrocyte sedimentation rate were 45 and 14 mm/h (p < 0.0005). The results indicate that certain patients with acute bronchitis should be treated with antibiotics, and that the erythrocyte sedimentation rate and the CRP-test may be useful in detecting which patients this applies to.

In 1990 and 1991 4522 blood samples from 398 pullet flocks and 1338 blood samples from 128 laying flocks were monitored for antibody against infectious bronchitis virus, infectious laryngotracheitis virus, adenovirus, reovirus, infectious bursal disease virus, Newcastle disease virus, Mycoplasma gallisepticum and Mycoplasma synoviae. The results are discussed for pullets and laying hens.

An epidemic often provides an opportunity to obtain evidence of the etiologic association of a microorganism with disease. Chlamydia pneumoniae TWAR is a newly recognized organism whose relationship to disease is not completely understood. An outbreak of C. pneumoniae infections from November 1990 to February 1991 was studied in University of Washington students. Twelve TWAR infections were identified serologically in 54 students with acute respiratory disease. The organism was isolated from 7 of the 12 and identified by the polymerase chain reaction (PCR) in 2 that were isolation-negative. The organism was not found in any of the 42 serologically negative patients or in 51 control student patients without respiratory illness cultured in 1991. There was no evidence of infection with Mycoplasma pneumoniae or respiratory viruses in the 12 patients with C. pneumoniae infection. During the 4-month outbreak, there was an increase in total pneumonia cases. These findings provide evidence for an etiologic association of C. pneumoniae with pneumonia and bronchitis.

During a 16-month period patients who presented to the Syracuse University Health Center with upper respiratory complaints had throat swabs obtained for viral, streptococcal and Mycoplasma pneumoniae cultures. Thirty-five of 613 patients (5.7%) had herpes simplex virus (HSV) isolated. All but 2 of the HSV isolates were found to be type 1 by immunofluorescent staining. Two HSV-positive patients also grew Group A Streptococcus, one grew M. pneumoniae and three had serum heterophile antibody tests that were positive. On physical examination 25 of the 35 HSV-positive patients had pharyngeal erythema and 14 had pharyngeal exudate. Twelve of these patients had vesicular lesions of the lips, throat or gums associated with their other symptoms. For 29 of the 35 HSV-positive students the primary diagnosis assigned was pharyngitis, for 2 the diagnosis was stomatitis and the remainder were assigned a primary diagnosis of upper respiratory infection, pneumonia, bronchitis or dental infection. Thirty-two of the 35 HSV-positive patients were treated with oral antibiotics and 7 were treated with oral or topical acyclovir. During the same 16-month period 89 (6.9%) of 1297 students presenting with sore throat were culture-positive for influenza A or B, 30 (2.3%) of 1283 were culture-positive for M. pneumoniae and 169 (2.8%) of the 6016 cultured for Group A Streptococcus were positive. Serum was tested for heterophile antibody in 2438 students, and 257 (10.5%) were positive. Herpes simplex virus is associated with pharyngeal symptoms in college students, and herpes simplex pharyngitis cannot easily be distinguished clinically from other causes of acute pharyngitis in this age group.

Mycoplasma pneumoniae causes not only pneumonia but also other respiratory syndromes such as bronchitis, bronchiolitis, pharyngitis, and croup. These infections mimic viral respiratory syndromes. Most cases are treated on an outpatient basis. Epidemics take place at intervals of 4-7 years. The incidence rate is highest among school children and second highest among children < 5 years of age. Among persons who have had M. pneumoniae pneumonia, rates of subsequent infection with this organism are low, and immunity appears to increase with age. The carrier state may last for several months. Patients with humoral immunodeficiency often develop severe infections due to M. pneumoniae, with involvement of the joints; in these individuals the carrier state may persist. M. pneumoniae has been isolated from bronchial washings from children with AIDS. These children have recovered from mycoplasmal infection with appropriate antibiotic treatment. Dermatologic, neurological, cardiac, renal, and pulmonary complications occur, although data on their frequency are lacking.

Five conventionally kept calves aged between 17 and 24 days were experimentally infected with bovine respiratory syncytial virus (BRSV) by aerosol in order to mimic the natural infection route. The calves were killed and autopsies performed 7 days after the first virus challenge. The BRSV isolate used induced tracheitis, bronchitis and atelectasis in infected calves. The only virus which could be isolated from the lungs of the calves was BRSV. In addition, Mycoplasma bovirhinis was isolated from the lungs or/and trachea of two calves. The clinical and histopathological findings, as well as the detection of BRSV antigens by immunofluorescence in the epithelial cells of lung and trachea, and the reisolation of the virus from bronchoalveolar lavage fluids of all inoculated calves, provided confirmation of successful infection with BRSV.

Azithromycin (AZM) was studied for its clinical efficacy in pediatric infections. The study on AZM was carried out in 43 patients whose diagnoses were given as follows: pharyngitis in five cases, tonsillitis in one, bronchitis in four, pneumonia in four, Mycoplasma pneumonia in 14, scarlet fever in nine, impetigo in four, pyodermia in one and Campylobacter enteritis in one. The patients received AZM once daily at 1.6 approximately 20.0 mg/kg body weight for three to five days. Effectiveness of AZM was evaluated in 39 cases and the drug was rated "excellent" in 15, "good" in 19, "fair" in one, "poor" in four, resulting in an efficacy rate of 87.2%. Twenty bacterial isolates were identified as causative isolates in 19 patients: Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Campylobacter jejuni and Mycoplasma pneumoniae. AZM eradicated 16 isolates but four persisted after therapy. One patient complained of loose stool, while two patients were found with decreases in white blood cell counts, and seven showed increases in eosinophils. However, no serious case of adverse event was reported.

Fine granule preparation of azithromycin (AZM), a new macrolide antibiotic, was given to treat various infections in pediatric patients. Efficacies of AZM in a total of 21 patients (tonsillitis in six, bronchitis in five, pneumonia in five, impetigo contagiosa in three, staphylococcal scalded skin syndrome in one and bacterial enterogastritis in one) were rated "excellent" in 11 patients and "good" in eight. The remaining two cases were not included in the evaluation. AZM eradicated all strains of infection-causative bacteria identified in the 21 patients: Staphylococcus aureus in two, Streptococcus pneumoniae in four, Moraxella (Branhamella) catarrhalis in four, Haemophilus influenzae in six, Haemophilus parainfluenzae in three and Mycoplasma pneumoniae in one. One patient complained of mild diarrhea, while two patients showed increases in eosinophils as abnormal laboratory changes.

Azithromycin (AZM) was studied for its concentrations in plasma and urine, efficacy and safety. 1. Plasma and urine samples were collected from one patient diagnosed as having Mycoplasma pneumonia for drug level determination. The drug was given once daily at 9.7 mg/kg body weight for three days. The drug concentrations in plasma was 0.149 microgram/ml in 12 hours after the start of the treatment, and 0.095 microgram/ml at the point of 24 hours after the end of the treatment. Urinary recovery rate up to 72 hours post-dosing was 6.39%. 2. The effectiveness of AZM was assessed in 19 patients with following diagnoses: pharyngitis in two patients, bronchitis in four, pneumonia in seven and Mycoplasma pneumonia in six. The drug was rated "excellent" in 11, "good" in seven, "poor" in one, resulting in an efficacy rate of 94.7%. 3. AZM eradicated two strains of Streptococcus pyogenes and Streptococcus pneumoniae identified in patients. 4. The AZM MIC's were 0.39 microgram/ml against Staphylococcus aureus, 0.20 microgram/ml against S. pneumoniae, < or = 0.0008 microgram/ml against Mycoplasma pneumoniae. 5. One patient complained of mild diarrhea, while another showed a slight increase in eosinophils, suggesting an abnormal laboratory change. In conclusion, AZM was found useful in treatment of pediatric infections.
