Some patients with Mycoplasma pneumoniae infection are clinically resistant to antibiotics such as erythromycin, clarithromycin, or clindamycin. We isolated M. pneumoniae from such patients and found that one of three isolates showed a point mutation in the 23S rRNA gene. Furthermore, 141 EM-sensitive clinical isolates of M. pneumoniae were cultured in(More)
We report the case of a 62-year-old man who developed eosinophilic pneumonia due to visceral larva migrans (VLM) that was possibly caused by Ascaris suum. The patient, a resident of the middle Kyushu area who was found of eating raw porcine liver, complained of dry cough without dyspnea. The chest radiography showed a migration of infiltrative shadow.(More)
We have examined 221 cases of mycoplasmal pneumonia in adults during the past 17 years. During this time epidemic waves occurred every three to four years. The incidence of disease was highest in patients 20 to 30 years of age. The most common clinical features were cough, fever, sputum, and rales. The most characteristic feature was a persistent cough(More)
Mycoplasma pneumoniae (MP) is one of the most common causes of community-acquired pneumonia in children and young adults. Although MP sometimes causes self-limiting pneumonia, severe and fulminant cases with hypoxia occur, but their clinical features have rarely been reported. This study aimed to reveal the clinical manifestations, risk factors, and(More)
A Mycoplasma pneumoniae cytadhesin P1 gene with novel nucleotide sequence variation has been identified. Four clinical strains of M. pneumoniae were found to carry this type of P1 gene. This new P1 gene is similar to the known group II P1 genes but possesses novel sequence variation of approximately 300 bp in the RepMP2/3 region. The position of the new(More)
A 77-year-old woman was admitted to our hospital complaining of high fever. The physical examination on admission indicated no abnormality. Although several antibiotics were administered, the spiking high fever was not alleviated. Two weeks after admission a macular rash appeared, and a high concentration of serum ferritin was observed. At this point,(More)
Although self-limited respiratory tract infections caused by Mycoplasma pneumoniae are well recognized in children and young adults, respiratory involvements and hepatic dysfunction may occur. The frequency and clinical features of these complications were investigated. Experimental studies with regard to bacterial superinfection were also carried out. The(More)
We isolated Bartonella henselae from an inguinal lymph node of a 36-year-old male patient with cat-scratch disease. The patient had many areas of erythema on his body, swelling of the left inguinal lymph nodes with pain and slight fever. The diagnosis was made on the basis of polymerase chain reaction for B. henselae DNA from the lymph node biopsies and(More)
A 50-year-old male with left cervical lymphadenopathy visited our hospital. Infectious and lymphomatous diseases were suspected in the patient. Since the patient owned a dog, which often licked the patient's face, Bartonella infection was also suspected. Histopathological examination in the lymph node biopsy revealed the epithelioid granuloma, but B.(More)
An adult case of pulmonary resection for repeated infections in a supernumerary tracheal bronchus combined with a pulmonary artery sling is reported. A 33-year-old woman with a pulmonary artery sling was referred for recurrent lung infections. Chest computed tomography showed the left pulmonary artery arising from the right pulmonary artery and coursing(More)
