The epidemiology, clinic, diagnostic dates and treatment of Legionella pneumophila (L. pneumophila) were discussion. The our study were removal in 246 workers seas drill platforms. The antibody opposed of L. pneumophila were mean in 54 with 246 workers. Investigation were execution into conjunction of specifically job and life workers and frequently appearance of bronchitis. The antibody L. pneumophila were detection in 25% persons. These dates may suggest possibilities of L. pneumophila infections among workers of these professions.

A 72-year-old man was exposed to the sarin gas attack in a Tokyo subway on March 20 th, 1995. After exposure, he noticed eye discomfort, chest tightness, headache and weakness of the lower limbs and oropharyngeal muscles. Despite these symptoms, he visited a hot spring on the same day with his family. On March 25 th, his muscle weakness progressed, and a low grade fever appeared. His muscle weakness disappeared 8 days after exposure to sarin, but respiratory failure rapidly developed, necessitating artificial ventilation within four day after hospitalization on March 28th. Chemotherapy with erythromycin, imipenem/cilastatin, and steroid pulse therapy was begu. PCR and culture of sputum collected by bronchofiberscopy were positive for Legionella pneumophila, serogroup I. His respiratory state improved, but subsequent infection with Pseudomonous aeruginosa. Enterobacter cloacae, and Candida tropicalis/glabrata caused his death 71 days after admission. Oropharyngeal muscle weakness caused by sarin-mediated cholinesterase inhibition was strongly suspected as the cause of hot spring water aspiration. Transbronchial lung biopsy revealed organizing pneumonia with fibrosis. Bronchoscopic findings included redness, edema and fragility of all visible areas of the airway, which was thought to be due to bronchitis caused by Legionellosis.

Occupational respiratory diseases have been reported following exposure to metal working fluids. We report a spectrum of respiratory illnesses occurring in an outbreak in 30 workers of an automobile parts engine manufacturing plant. Workers presented with respiratory complaints and, after clinical and laboratory evaluations, were classified as those having hypersensitivity pneumonitis, occupational asthma, or industrial bronchitis, or those without occupational lung disease. Hypersensitivity pneumonitis affected seven workers, with six exhibiting serum precipitins to Acinetobacter Iwoffii. Occupational asthma and industrial bronchitis affected 12 and six workers, respectively. Oil-mist exposures were below current recommendations. Gram-negative bacteria, but no fungi, Thermophiles, or Legionella, were identified. Although specific agents responsible for each individual case could not be identified, probably both specific sensitizing agents and non-specific irritants from metal working fluids, additives, or contaminants contributed to this spectrum of occupational respiratory illness.

Bronchitis obliterans organizing pneumonia (BOOP) is an unusual pulmonary condition. The clinical features and the radiologic findings are useful for the diagnosis of BOOP. However it is necessary to confirm its presence by an open or transbronchial pulmonary biopsy specimen. BOOP is usually idiopathic, although it may also occur in association with connective tissue disease, some haematologic disorders and in response to viral infections. The association of Legionella pneumophila infection with BOOP is very rare.

We assessed the frequency and clinical significance of polymicrobial infections in 31 patients with sporadic community-acquired Legionella pneumonia. Twenty-six patients were men, 5 were women and mean age was 61 years. Eighteen patients were smokers, 6 patients were chronic alcoholics and 23 had underlying diseases. Regarding severity, the illnesses were mild (two patients), moderate (seven patients) and severe (twenty-two patients). In 9 (29%) of the patients, one other etiologic agent for community-acquired pneumonia was identified in addition to the Legionella species. The distribution of one other causal agent was as follows: Mycoplasma pneumoniae, 2 patients; Chlamydia pneumoniae, 2; Chlamydia psittaci, 1; Influenza virus, 1; Streptococcus pneumoniae, 1; Klebsiella pneumoniae, 1; Pseudomonas aeruginosa, 1 patient. Because an antimicrobial agent with activity against Legionella species can also provide coverage for Mycoplasma pneumoniae. Chlamydia pneumoniae, and Chlamydia psittaci, the patients with these coinfections improved without any complications. The patient with influenzavirus coinfection became seriously ill, and the condition was complicated by disseminated intravascular coagulation, renal failure and aspergillus bronchitis. The case of Pseudomonas aeruginosa coinfection was accompanied with a lung abscess and empyema. Our experience illustrates the importance of considering polymicrobial infections in patients with sporadic community-acquired Legionella pneumonia.

"Q fever" is a generic term for infection caused, mostly in the form of pneumonia or bronchitis, by Coxiella burnetii (Q-fever Coxiella), a pathogen closely related to Rickettsia and Legionella. Q fever is an influenza-like, transient febrile infectious disease that is common to humans and animals; it develops after the transmission of the infectious agent from livestock or pet animals, but person-to-person transmission is rare. In Europe and the United States, it is ranked fourth or fifth as an underlying cause of community-acquired pneumonia. Many patients with Q fever have a good prognosis, and their mortality is about 1%-2% when left untreated. However, because some patients may take a long time to be cured or may have a chronic condition with poor prognosis, patients with definitely diagnosed Q fever or those strongly suspected of having Q fever are strongly recommended to receive treatment. The definite diagnosis of Q fever is made based on a significant increase in serum antibody titers, the determination of which often requires considerable time, and therefore patients must be monitored for a certain period. Q-fever Coxiella, an obligate intracellular parasite, is basically not susceptible to beta-lactam antibiotics, which barely permeate into the cells, but the parasite is susceptible to tetracyclines, macrolides, and quinolones, with these agents being sufficiently permeable into the cells. However, there are many cases of spontaneous cure, and it is likely that beta-lactam treatment may have been involved in these cases. Vaccination against Q fever is not common in Japan.
