The pulmonary histopathologic features in a sporadic case of Legionnaires' disease are shown. The changes include acute bronchitis with focal ulceration and diffuse acute interstitial pneumonitis. These changes are not those seen with typical bacterial pneumonia but are similar to changes seen when viruses, rickettsiae, chlamydiae, or Mycoplasma pneumoniae organisms are the infecting agents.

Experimentally induced and naturally acquired lungworm infections (Didelphostrongylus and Capillaria) were studied in opossums, Didelphis marsupialis. Each of 4 helminth-free opossums were experimentally infected with 250 3rd-stage Didelphostrongylus hayesi larvae. At 2 and 8.5 months after infection, 2 animals were necropsied. Hypertrophy of pulmonary smooth muscle characterized D hayesi infections, with lesions pronounced in the vicinity of helminths. There was mucous bronchitis characterized by peribronchial gland hyperplasia, lymphoid nodule formation, and exudation of mucus and eosinophils into bronchioles. Lung from 4 opossums harboring natural infections of D hayesi or Capillaria or both was examined. Concomitant infections produced multifocal, indurated lesions often resulting in generalized consolidation. Microscopic examination revealed pulmonic damage consisting of hypertrophy of smooth muscle, extensive peribronchiolar adenomatoid hyperplasia of alveolar epithelium, and diffuse areas of granulomatous interstitial pneumonia. Capillaria provoked well-defined granulomas, and frequently only eggs and cuticular debris were contained within the lesions. Loss of pouch young by 1 naturally infected feamle was associated with extensive verminous pneumonia.

Primary or secondary infection of the lungs with fungi of the Paecilomyces family (P. variotii and P. viridis) gives rise to the development of infectious allergic bronchopulmonary paecilomycosis characterized by the presence of chronic allergic interstitial pneumonia and obstructive bronchitis, bronchial asthma, total and pulmonary eosinophilia, the presence of the tissue parasitic form of the fungus in sputum, blood, pulmonary tissue, the presence of allergen-specific IgE and/or IgG antibodies in patients' sera, immediate or double (20 min and 6 h) reaction of the skin to administration of allergen of Paecilomyces, by not infrequent combination of lung damage and impairment of other organs as well as by chronic relapses.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

Five cases of the respiratory infections, in which Neisseria meningitidis was isolated upon the examination of the transtracheal aspiration (TTA), were reported. Patients studied were four males at the ages of 18, 56, 66 and 78 years, and a 18-year old female. Five cases were bronchopneumonia (two cases), acute bronchitis (two cases) and diffuse panbronchiolitis (DPB) (one case). Underlying diseases were as follows: lung cancer or acute myocardial infarction in cases of bronchopneumonia, and interstitial pneumonia or pulmonary tuberculosis in cases of acute bronchitis. There was a case in which only N. meningitidis was cultured from specimens obtained by TTA, although another different organism, in addition to N. meningitidis, was recovered from the patient of other cases. Other organisms found together with N. miningitidis were H. influenzae (2 cases), S. dysgalactiae (1 case) and M. tuberculosis (1 case). Predisposing factors were common cold in the female patient and bronchoscopic examination in the cases of lung cancer and of interstitial pneumonia. Two of the five cases occurred consecutively in the same room and so they were considered as nosocomial infections. With these findings, it can be posturated that N. meningitidis might be one of the etiological agents of the respiratory infections.

The immune suppression required after organ transplantation is accompanied by an elevated risk of infection by conventional and opportunistic pathogens. The lungs are the organs that are most commonly affected. Following transplantation of the kidney, pulmonary diseases have dropped from 23% to less than 5%. After bone marrow grafting, bacterial pneumonia, fungal pneumonia, bronchitis, mixed bacterial and fungal pneumonia, interstitial viral pneumonia, unclear pulmonary infiltrates, idiopathic interstitial pneumonia, pneumonia due to rare pathogens, obstructive bronchitis, and ARDS can occur. CMV pneumonia can be avoided by immunoglobulin prophylaxis, the use of CMV-negative leukocyte free blood - and platelet transfusions. The CMV pneumonia occurs as a result of a lymphocytic reaction. Obstructive bronchiolitis is probably caused by activated lymphocytes following bone marrow grafting, via the graft-versus-host reaction, and following heart-lung transplantation by the rejection reaction.

The experiments on rats show that the 4-month elevated air dryness has no impact on body accumulation of 239Pu but causes more distinct forms of bronchitis and interstitial pneumonia combined with the strain in medullary hemopoiesis and reactivity intensification of pulmonary and B-system immunity. Under prolonged effect of both factors a breakdown in fully adequate immune response can occur.

Six- to eight-week-old gnotobiotic F344/N rats were inoculated intranasally with 10(5.0) colony-forming units of Mycoplasma pulmonis or were sham inoculated, then one week later were given 10(0.2) 50% tissue culture infective doses of Sendai virus or sterile medium. Groups of rats were killed immediately after virus inoculation and three, five, ten, and 20 days later. Lesions in nasal passages, middle ears, larynxes, tracheas, and lungs from half of the rats in each group were subjectively scored. Organs from the other rats were quantitatively cultured for M. pulmonis and for Sendai virus. Rats given Sendai virus alone had mild, patchy, necrotizing rhinitis, laryngitis, tracheitis, and bronchitis, but not bronchiolitis or interstitial pneumonia. M. pulmonis alone induced mild lesions of murine respiratory mycoplasmosis including mild to moderate suppurative rhinitis, otitis media, laryngitis, and tracheitis with submucosal lymphoid accumulation and epithelial hyperplasia, but not lung lesions. Rats given M. pulmonis and Sendai virus had severe lesions characteristic of advanced mycoplasmal disease throughout the respiratory tract, including suppurative bronchitis with extensive lymphoid accumulations and epithelial hyperplasia; some rats also had suppurative pneumonia and bronchiectasis. Larger numbers of M. pulmonis colony-forming units were in rats given Sendai virus, but there was no statistically significant difference in Sendai virus infectious units between rats also given M. pulmonis and those given virus only.

Young beagle dogs were experimentally inoculated with canine adenovirus Type 2 and studied by virologic, histologic, immunoperoxidase, and ultrastructural methods from 1 to 26 days after inoculation. Virus was recovered from lungs at 2, 3, 5, and 8 days after inoculation. Virions and viral antigen were demonstrated by ultrastructural and immunoperoxidase techniques in nonciliated bronchiolar epithelial cells and mucous cells in bronchioles, bronchi, and trachea as well as in bronchial and tracheal submucosal gland epithelial cells. Viral replication in airways was associated with a severe necrotizing and proliferative bronchitis and bronchiolitis. Virus and viral antigen were demonstrated in Type 2 alveolar epithelial cells and were associated with interstitial pneumonia. Partial and complete stenosis of bronchioles by connective tissue was observed at 15 and 26 days after inoculation. There was a 50% reduction (P less than 0.02) in mean terminal bronchiolar cross-sectional area in the right middle lobe of virus-infected dogs at 26 days after inoculation. It is concluded that experimental adenovirus infection in dogs induces bronchiolitis obliterans and that this experimental model may be useful for studies on adenovirus-induced lung injury during early life.

Respiratory syncytial virus (RSV) is the most frequent cause of serious respiratory tract infections in infancy. In the course of a one-year study the nasopharyngeal secretions of all hospitalized children with diseases of the lower respiratory tract (almost exclusively infants) were examined for viral antigens. RSV antigen could be detected in 34 of the 71 secretions. In these infants a serious clinical course, pneumonia, bronchiolitis or obstructive bronchitis was dominant, but laboratory tests showed no characteristic pattern. Pulmonary X-rays of the RSV-infected infants revealed interstitial pneumonia with or without pulmonary infiltration, in addition to symptoms of hyperinflation. We were able to examine 21 of 33 RSV-infected infants 2 years later.
