Abstract: La enfermedad pulmonar por micobacterias ambientales es una entidad clínica conocida, siendo el Mycobacterium avium complex el patógeno involucrado con más frecuencia. El síndrome de Lady Windermere es una variedad de esta enfermedad, tan interesante como poco conocida. Pulmonary disease due to nontuberculous myco bacteria is a well known clinical entity, being Mycobacterium avium complex the pathogen most frequently involved. The Lady Windermere syndrome is a variation of this disease, as interesting as it is little known.
Concurrent pulmonary Mycobacterium avium complex (MAC) infection and active Hürthle cell thyroid carcinoma: is there a connection?  [PDF]
Kara M. Meinke Baehr, Whitney S. Goldner
Health (Health) , 2010, DOI: 10.4236/health.2010.25058
Abstract: We present two cases of pulmonary MAC infection in women with Hürthle cell thyroid carcinoma. Both cases were asymptomatic octogenarian women with active Hürthle cell thyroid carcinoma and prolonged periods of hypothyroidism prior to diagnosis of pulmonary MAC. Mycobacterium avium complex has never been reported in association with any type of thyroid cancer, specifically Hürthle cell carcinoma. A review of the literature and possible associations between the two are discussed in this article.

Iranian Journal of Microbiology , 2010,
Abstract: Background and Objectives: Pigeons are extensively kept for homing and racing purposes in Iran. The main objective of this study was to investigate dissemination of M. avium subsp. avium (MAA) in pigeon aviaries in Tabriz, North-western Iran."nMaterials and Methods: Postmortem pathologic specimens from thirty-nine out of 140 birds collected from private flocks (n = 3), were subjected to bacterial culture out of which 3-4 mycobacterial isolates were recovered."nResults: Applying a five-PCR diagnostic algorithm targeting short but definitive stretches of 16S rRNA and RV0577 genes, IS6110, IS901 and IS1245 genomic loci, proved all the isolates were MAA. They were either IS901+/IS1245+ (n = 22) or IS901+/IS1245- (n = 12)."nWhen four healthy cattle sensitized against Mycobacterium bovis AN5 and Mycobacterium avium D4 were tuberculinated, the results confirmed the observed skin reactions against bovine tuberculin in animals sensitized with M. avium were large enough to complicate test interpretation."nConclusion: We believe the extent of such epidemiological impact deserves further investigation if progress in control of bovine tuberculosis is intended.

Infectious Disease Reports , 2013, DOI: 10.4081/idr.2013.e2
Abstract: Acquired immunodeficiency syndrome patients are known to have an increased tendency for developing opportunistic infections. However, there are no reports of simultaneous lymph node involvement of cytomegalovirus and Mycobacterium avium complex in a human immunodeficiency virus-positive patient. We report a 31-year-old man who presented with acute abdominal pain and tenderness and weight loss. He died a few hours after admission. Autopsy studies showed coinfection of cytomegalovirus, Mycobacterium avium complex and human immunodeficiency virus. Our case emphasizes the need to be careful in evaluating opportunistic infections in severely immunodepressed acquired immunodeficiency syndrome patients. This case report is the first manifestation of acquired immunodeficiency syndrome in this patient.

Abstract: Se estudiaron diferentes tipos de muestras procedentes de una paciente de 27 a os, diagnosticada como paciente SIDA luego de haber presentado un cuadro respiratorio agudo provocado por Pneumocistis carinii en 1997. A partir de ese momento la paciente siguió presentando cuadros respiratorios a repetición, hasta que ingresó en el Instituto de Medicina Tropical "Pedro Kourí" con cuadro diarreico crónico, pérdida de peso importante y anorexia extrema, acompa ada de una constante tos húmeda, fiebre, etc. Se le realizaron los exámenes complementarios necesarios donde se resalta, un mantoux hiperérgico y niveles de células CD4 muy bajos (por debajo de 200 células/m3, conjuntamente se realizan estudios microbiológicos a partir de muestras de esputos, hemocultivos y líquido cefalorraquídeo, para descartar la presencia de bacilos ácido-alcohol resistentes. Como resultado de estos estudios se logró el aislamiento repetitivo en todos los tipos de muestras trabajadas de una cepa de crecimiento lento, cremosa no pigmentada, perteneciente al grupo III de Runyon, la cual fue clasificada como perteneciente al complejo Mycobacterium avium-intracellulare. La paciente fue sometida a tratamiento con 4 drogas antibacilares, sin obtener resultado, pues a las 4 semanas de tratamiento falleció a causa de la diseminación total de esta infección. Se debe destacar que este ha sido el primer caso reportado y diagnosticado microbiológicamente de mycobacteriosis generalizada en paciente VIH+ por Mycobacterium avium-intracellulare. Different types of samples from a 27-year-old female patient who was diagnosed AIDS after presenting an acute respiratory picture caused by Pneumocistis carinii, in 1997, were studied. From that moment on, the patient continued having respiratory pictures repeatedly, until she was admitted at "Pedro Kouri" Institute of Tropical Medicine with a chronic diarrheical picture, significant loss of weight and extreme anorexia, together with a constant wet cough, fever, etc. The necessary complementary tests were made and a hyperergic Mantoux and very low levels of CD4 cells (under 200 cells/m3) outstood. Microbiological studies were also conducted with samples from sputum, hemocultures and cerebrospinal fluid to discard the presence of acid-alcohol resistant bacilli (AARB). As a result of these studies, the repeated isolation was obtained in all types of worked samples from a slow-growth , creamy and non pigmented strain corresponding to Runyon’s group III, which was classified as from the Mycobacterium avium-intracellulare complex. The patient was treated with an

Abstract: La enfermedad provocada por micobacterias ambientales es sospechada fundamentalmente en pacientes HIV positivos o con otras enfermedades de base. En nuestro país no hay información actualizada acerca de la prevalencia, tratamiento y evolución de esta enfermedad en pacientes inmunocompetentes. Presentamos 10 casos de enfermedad pulmonar por micobacterias ambientales en pacientes inmunocompetentes: diagnóstico clínico-bacteriológico, tratamiento y evolución. Pulmonary disease, due to Mycobacteria other than tuberculosis, is mainly suspected in HIV + patients, or underlying other diseases. In our country, there is no updated information on the prevalence of this pulmonary disease, its treatment and evolution in immucocompetent patients. We present 10 cases of pulmonary disease due to Mycobacteria other than tuberculosis in non HIV patients: clinical-bacteriological diagnosis, treatment and evolution.

Abstract: introduction: mycobacterium genus includes species of m. tuberculosis complex and others called non-tuberculous mycobacteria (ntm). so far, more than 100 species of ntm have been described. the objectives of this study were to estimate the ntm species diversity among strains isolated in s?o paulo state from 1991 to 1997, before the expansion of antiretroviral therapy, and to evaluate the rate of cases that fall under diagnostic criteria for bacteriological diagnosis of ntm infections. material and methods: 1,892 strains were isolated from sterile and non-sterile sites of 1,248 patients. results: 1,199 (96%) were identified as m. avium complex (mac), m. kansasii, m. chelonae, m. fortuitum, m. szulgai, m. xenopi, m. marinum, m. gordonae, m. terrae or m. nonchromogenicum whereas 49 (3.9%) couldn't be identified up to species. forty-seven (7,8%) cases from pulmonary sites were confirmed based on strains isolated from three or more samples from the same patient and 67 (34%) patients had ntm isolated from sterile sites, which confirmed the bacteriological diagnosis. conclusions: mac and m. kansasii were the most frequently especies isolated in s?o paulo state. national recomendations for the diagnosis and treatment of ntm infections would be useful for correct management of ntm infections.

Abstract: objective evaluating the frequency of mycobacterium infection in an hiv-positive population and its influence on medium-term survival, along with clinical and epidemiological factors associated with co-infection. methods several clinical specimens were studied for mycobacteria in a sample of 92 hiv+ patients at the san juan de dios teaching-hospital in bogota, colombia, during 1996. factors associated with infection were measured using a prevalence ratio (pr), ci=95%, and logistic regression was used in the multivariable models. the likelihood of survival for three months was measured using kaplan-meir curves and factors associated with survival were assessed using rate ratios and cox's model. results eight percent of the patients had tuberculosis and 6% of them were found to be infected with atypical mycobacterium. mycobacterium avium complex (mac) was the most frequent species, followed by m. fortuitum and m. chelonae. mixed infections with m. tuberculosis and mac were diagnosed in one patient and two different species of atypical mycobacterium were isolated in other two cases. patients suffering from tuberculosis and stages iii or iv hiv infection had a 16% survival rate. conclusions tuberculosis-hiv/aids frequency and atypical mycobacterium-hiv/aids' association were very similar. the most frequently isolated atypical mycobacterium specie in this study was mac. survival rate was lower for patients infected by m. tuberculosis and even lower when a multi-resistant strain was involved. the most important clinical factor associated with m. tuberculosis was the presence of fever and loss of weight with mycobacterial infection. blood provided the best samples for isolating mycobacteria.
