1/10. mycobacterium avium-intracellulare in stool in HIV-seropositive man.

    mycobacterium tuberculosis is the predominant acid-fast bacillus causing diarrhea in HIV-seropositive patients in india. We report a 27-year-old HIV-seropositive man with diarrhea in whom M. avium-intracellulare was isolated on stool culture.

2/10. rhodococcus equi cavitary pneumonia in HIV-infected patients: an unsuspected opportunistic pathogen.

    Two patients seropositive for human immunodeficiency virus (HIV) and with no previous acquired immunodeficiency syndrome-defining conditions developed cavitary pneumonia and pleural disease caused by rhodococcus equi. R. equi was isolated from these patients' sputum and lung biopsy specimens, respectively, but the microorganism was initially considered to be a contaminant (patient 1) or misidentified as a nontuberculous mycobacterium (patient 2). The R. equi infection was fatal in one patient, who died after 4 months without specific antimicrobial therapy; the second patient was unresponsive to combination therapy with various antimicrobial agents. R. equi may cause life-threatening infections in HIV-infected patients. microbiology laboratories should be cognizant of the need to exclude R. equi as a cause of infection in highly immunosuppressed patients.

3/10. Mycobacterium malmoense infection in HIV positive patients.

    Mycobacterium malmoense is a non-tuberculous mycobacterium which has previously been associated with underlying pulmonary pathology and depressed immunity. We describe two patients infected with human immunodeficiency virus from whom M. malmoense was isolated, and discuss its treatment and possible pathogenic role.

4/10. Choroidal granuloma caused by atypical mycobacterium in a patient with AIDS: a case report.

    The case presented is a chorioretinal granuloma in a patient with AIDS. The neoformation appeared to be caused by atypical mycobacterium, although it was not possible to isolate the germ. The chorioretinal infection caused by atypical mycobacterium in patients with AIDS occurs very rarely and has so far been described only as a post-mortem finding.

5/10. rhodococcus equi causing human pulmonary infection: review of 29 cases.

    rhodococcus equi is a gram-positive pleomorphic bacillus that has been identified as a life-threatening pulmonary pathogen in the immunocompromised host. Infection with R equi may go unrecognized by physicians unacquainted with its presentation and unaware of the organism's ability to mimic diphtheroids and to stain weakly positive with an acid-fast stain.

6/10. Infection-associated vascular lesions in acquired immunodeficiency syndrome patients.

    Several reports have recently appeared in the literature describing "unique" non-neoplastic vascular lesions in patients with the acquired immunodeficiency syndrome (AIDS). These lesions may be mistaken clinically and histologically for Kaposi's sarcoma. The terms epithelioid angiomatosis, epithelioid or histiocytoid hemangioma, and pyogenic granuloma have all been used to describe a similar entity in which cat scratch disease bacillus (CSDB) was subsequently identified. Lesions closely resembling this entity occur in patients with bartonellosis. We report a case of a cutaneous vascular lesion on the hand of an AIDS patient in which cytomegalovirus (CMV) and organisms consistent with CSDB were both found. Simultaneous infections with CMV and CSDB have not been previously described. The presence of these organisms in and around endothelial cells may provide the common stimulus for the formation of these reactive vascular proliferations.

7/10. Cytologic appearance of rhodococcus equi in bronchoalveolar lavage specimens. A case report.

    Immunocompromised patients are at risk of developing infections caused by rhodococcus equi, a gram-positive bacillus that can cause pneumonia in patients with acquired immunodeficiency syndrome. To the author's knowledge this is the first report describing the cytologic features of the infection in a patient who had a confirmatory tissue biopsy and positive culture. Infection with R equi may go unrecognized by pathologists unaware of its presentation and appearance in cytologic material.

8/10. actinobacillus (pasteurella) ureae meningitis in a HIV-positive patient.

    actinobacillus (pasteurella) ureae is a commensal of the human nasopharynx that is a rare cause of meningitis. We present an HIV-infected patient with this condition. His case, and those previously reported in the literature, implicate head trauma or a neurosurgical procedure in the pathogenesis of this condition. The patient responded to initial empiric therapy with ceftriaxone, followed by intravenous penicillin.

9/10. Disseminated bacillus Calmette-Guerin infection in an HIV-infected child: a case with cutaneous lesions.

    A boy born to a mother with unknown HIV infection was immunized with BCG in his first month of life. Seven months later axillary adenopathy developed. At the age of 10 months, 2 months after HIV infection had been diagnosed, papular skin lesions appeared all over his body. mycobacterium bovis, BCG strain, was cultured from a lymph node and blood. Ziehl-Neelsen stain of a skin biopsy specimen showed histiocytes loaded with numerous acid-fast bacilli. The patient died 10 days later, before the infection was confirmed. This is the first reported case of disseminated BCG infection in an HIV-infected child presenting with cutaneous lesions.

10/10. HIV associated chronic atypical osteomyelitis by mycobacterium fortuitum--Chelonae group--a case report.

    In developing countries where tuberculosis is endemic, the HIV patients have tuberculosis as one of the major opportunistic infections. Commonly M. tuberculosis, M. Avium-intracellular are the causative agents of pulmonary, extra-pulmonary and disseminated infection in AIDS patients. Here is a report of a 32 year old HIV positive male who presented as chronic atypical osteomyelitis of right tibia. Core biopsy confirmed the diagnosis by histopathology, direct microscopy and culture of M. fortuitum-chelonae group identified by the biochemical tests. TB IgG ELISA was strongly positive. ELISA for hiv antibodies was reactive on three occasions. Western blot was positive for hiv-1 antibodies. Patient responded well to ciproflox and antitubercular treatment and is currently under a follow up.
