Drug sensitivity tests were performed for ethambutol, rifampicin, streptomycin, and isoniazid both alone and in paired combinations, on 16 strains of Mycobacterium avium intracellulare, seven strains of Mycobacterium xenopi, and eight strains of Mycobacterium malmoense. Most strains were resistant to the individual drugs, but all strains of M malmoense, 86% of M xenopi, and 31% of M avium intra...

Ninety-seven cultures of Myco, tuberculosis referred to the Tuberculosis Reference Laboratory, Cardiff during 1972-73 and found to be resistant to rifampicin or ethambutol were studied. Resistance to each drug appeared equally common. Few lower grades of rifampicin resistance occurred, cultures tending to be either fully sensitive or highly resistant. Intermediate grades of ethambutol resistanc...

Progress in understanding the structure-function relationships of the mycobacterial cell wall has been hampered by its complex architecture as well as by the lack of sensitive, high-resolution probing techniques. For the first time, we used atomic force microscopy (AFM) to image the surface topography of hydrated Mycobacterium bovis bacillus Calmette Guérin cells and to investigate the influenc...

We evaluated the performance of BACTEC MGIT 960 for automated testing of the susceptibility of 133 strains of Mycobacterium tuberculosis to streptomycin, isoniazid, rifampin, and ethambutol. The BACTEC MGIT 960 results were compared with those obtained with the radiometric BACTEC 460TB system, and when there was disagreement, the method of proportion on agar plates was used as a reference metho...

A 61-year-old man was admitted to our hospital on September 2021 because of a three-month history fatigue, night sweats, and weight loss. The patient had been diagnosed with organized pneumonia treated methyl prednisolone at local hospital. One week before presentation hospital, he developed fever, cough, sputum shortness breath. Upon admission acid-fast resistant bacteria (ARB) urine ARB were ...

In the title compound, C(14)H(12)ClNO(2), the mean plane through the amide group [-N-C=O-] forms dihedral angles of 27.55 (8) and 31.94 (7)° with the meth-oxy- and chloro-substituted benzene rings, respectively. The dihedral angle between the benzene rings is 59.24 (4)°. In the crystal, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis.

Changing climate is expected to alter precipitation patterns in the Arctic, with consequences for subsurface temperature and moisture conditions, community structure, and nutrient mobilization through microbial belowground processes. Here, we address the effect of increased snow depth on the variation in species richness and community structure of ectomycorrhizal (ECM) and saprotrophic fungi. S...
