OBJECTIVE To establish recovery rates of atypical mycobateria from stools of suspected AIDS patients using culture media. DESIGN Laboratory evaluation of recovery rates, contamination rates, optimum exposure time and optimum concentration of alkali used for decontamination. SETTING The study was conducted in Harare, Zimbabwe at two medical institutions: Beatrice Road Infectious Diseases Hos...

The role of antigens shared between Mycobacteria in in-vivo cross-reactive immune responses in host animals, have been reported to be responsible for reduced BCG vaccination efficacy as well reduced specificity of routine immunological diagnostic tests. This presents with significant disease control challenges in humans and animals. The present review highlights the results of previous studies ...

Pa vias, M., Patlokova, Vlasta: Occurrence of Mycobacteria in Sawdust, Straw, Hay and Their Epizootiological Significance. Acta vet. Bmo, 54, 1985: 85-90. The occurrence of mycobacteria in sawdust and straw used as bedding material in cattle and pig herds was investigated using 147 sawdust and straw samples from 47 farms. The most important epizootiological finding was the demonstration of nine...

Atypical mycobacteria have been described as long as 36 years ago, but it has only been in the last 10 years that the ability of these organisms to cause disease in man has been recognized. The most common pathological processes with which the atypical mycobacteria are associated occur in the lungs and in the cervical lymph nodes. More rare is joint pathology. We describe here a case of knee ar...

Although AIDS patients in other countries are frequently diagnosed as having atypical mycobacterial infection, in Southern Brazil there is a clinical impression that Mycobacterium tuberculosis is the rule rather than the exception. We made a retrospective review of cultures for mycobacteria at our hospital in order to determine the frequency of atypical mycobacteria and Mycobacterium tuberculos...

  Introduction: Development of effective immunodiagnostic methods for detection of Mycobacterium tuberculosis infection is crucial. Serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (TB) control. In this study, the level of IgG antibody responses...

Atypical mycobacteria are increasingly afflicting pulmonary and extra pulmonary systems. Disease caused by these organisms are less common compared with tuberculosis caused by human strain of mycobacteria, but there has been a significant increase in pulmonary and extra pulmonary infections due to atypical mycobacteria especially in retroviral disease in the last two decades. 75 HIV positive pa...

In veterinary medicine the increasing attentions have been paid to the potential role of atypical mycobacteria as opportunist pathogens in animal health as a result of the successful contl'ol of bovine tuberculosis, as reviewed by Kazdall. This tendency will be partially explained from the fact that one is tempted to interpret the occuHence of the so-called no visible lesion reactors, a very pe...

A 45-year-old, non-obese male presented with low-grade, remittent fever and a fluctuant swelling over the posterior aspect of his lower left flank. Laboratory tests revealed leukocytosis, raised ESR, hyperglycemia and raised HbA1C levels. Light microscopy of Ziehl-Neelsen-stained pus sample revealed numerous acid-fast bacilli. After 72 h of incubating aspirated pus in Löwenstein-Jensen media, n...

BACKGROUND Atypical mycobacteria are a heterogeneous group of organisms that are of increasing importance because of the growing number of infections they cause. This rising rate of infection is due mainly to the increase in the number of susceptible (and especially immunosuppressed) patients. OBJECTIVE To revise the currently used treatment schemes of the most commonly isolated atypical myco...
