In recent years there has been an increase in the incidence of nontuberculous mycobacteriosis, particularly of Mycobacterium avium complex lung disease, among people without HIV infection in many countries [1]. In Japan, the estimated incidence rate of nontuberculous mycobacteriosis in the 1970s was around 1.0 per 100,000 populations, but by 2007 it had risen to about 5.8 per 100,000, the highe...

We report microbiologic analysis of 786 lymph node biopsy specimens from patients with suspected cat-scratch disease (CSD). The specimens were examined by standard, cell culture, and molecular methods. Infectious agents were found in samples from 391 (49.7%) of 786 patients. The most commonly identified infectious agent was Bartonella henselae (245 patients, 31.2%), the agent of CSD. Mycobacter...

Thirty-six patients with AIDS and culture-proven nontuberculous mycobacteriosis were compared to 20 patients with acquired immunodeficiency syndrome (AIDS) and tuberculosis with regard to clinical signs, symptoms, and diagnostic methods. Patients with nontuberculous mycobacteriosis were more often younger and homosexuals, while patients with tuberculosis were usually Haitian-American or users o...

OBJECTIVES To clarify the clinical features of the coexisting lung cancer and nontuberculous mycobacteriosis of the lung. MATERIALS AND METHODS We analyzed clinical data on 11 admitted cases of coexisting lung cancer and pulmonary non-tuberculous mycobacteriosis at National Organization Tokyo Hospital during the period from 1997 to 2002. RESULTS There were 10 men and 1 woman, with a mean ag...

The Columbia basin subpopulation of pygmy rabbit Brachylagus idahoensis was listed as endangered by the United States Fish and Wildlife Service in November 2001, and no pygmy rabbits have been seen in the wild since spring 2002. Captive propagation efforts have attempted to increase population size in preparation for reintroduction of animals into central Washington. Disseminated mycobacteriosi...

Systemic mycobacteriosis was diagnosed in a group of ornamental fish. Although a large number of acid-fast bacterial rods were identified in the kidneys, liver, and muscles of each fish, no granulomas were observed in internal organs. Mycobacterium peregrinum was identified using the GenoType Mycobacterium CM assay. This study illustrates a considerable risk of atypical mycobacteriosis in humans.

Primary atypical mycobacteriosis of the lung is comparatively common but primary atypical mycobacteriosis of the intestine had not been described previously in the English literature. We have treated three such patients with antituberculous drugs and the clinicopathological findings and course are described. We suggest that these findings may belong to a new clinical entity.

Avian mycobacteriosis was diagnosed in one female Mauritian Pink pigeon (Nesoenas mayeri) from a zoological collection. The bird displayed clinical symptoms of apathy, loss of body weight, ruffled feathers and diarrhoea. Necropsy revealed nodular lesions in the internal organs. Mycobacterium avium subsp. avium was isolated and also directly detected using qPCR in the female’s liver. Avian mycob...
