1/19. mycobacterium marinum infection from a tropical fish tank. Treatment with trimethoprim and sulphamethoxazole.A paronychial granuloma on the left thumb, in a man who kept tanks of tropical fish, was followed by cutaneous nodules on the left upper limb and tender lymph nodes in the left axilla. mycobacterium marinum was isolated from the lesion on the thumb and also from the tank water. Subsidence of the lesions followed administration of trimethoprim and sulphamethoxazole.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
2/19. Localized primary cutaneous mycobacterium kansasii infection in an immunocompromised patient.mycobacterium kansasii is a rare primary cutaneous pathogen, most commonly affecting persons exposed to contaminated water, particularly after local trauma. Most patients who present with localized primary cutaneous M kansasii infection are immunocompetent, whereas the majority of patients with disseminated or pulmonary infection are immunocompromised. We describe a primary cutaneous M kansasii infection in an iatrogenically immunosuppressed patient.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
3/19. Characterization of Mycobacterium bohemicum isolated from human, veterinary, and environmental sources.Chemotaxonomic and genetic properties were determined for 14 mycobacterial isolates identified as members of a newly described species Mycobacterium bohemicum. The isolates recovered from clinical, veterinary, and environmental sources were compared for lipid composition, biochemical test results, and sequencing of the 16S ribosomal dna (rDNA) and the 16S-23S rDNA internal transcribed spacer (ITS) regions. The isolates had a lipid composition that was different from those of other known species. Though the isolates formed a distinct entity, some variations were detected in the features analyzed. Combined results of the phenotypic and genotypic analyses were used to group the isolates into three clusters. The major cluster (cluster A), very homogenous in all respects, comprised the M. bohemicum type strain, nine clinical and veterinary isolates, and two of the five environmental isolates. Three other environmental isolates displayed an insertion of 14 nucleotides in the ITS region; they also differed from cluster A in fatty alcohol composition and produced a positive result in the Tween 80 hydrolysis test. Among these three, two isolates were identical (cluster B), but one isolate (cluster C) had a unique high-performance liquid chromatography profile, and its gas liquid chromatography profile lacked 2-octadecanol, which was present in all other isolates analyzed. Thus, sequence variation in the 16S-23S ITS region was associated with interesting variations in lipid composition. Two of the isolates analyzed were regarded as potential inducers of human or veterinary infections. Each of the environmental isolates, all of which were unrelated to the cases presented, was cultured from the water of a different stream. Hence, natural waters are potential reservoirs of M. bohemicum.- - - - - - - - - - ranking = 2keywords = water (Clic here for more details about this article) |
4/19. Disseminated Mycobacterium abscessus infection manifesting as fever of unknown origin and intra-abdominal lymphadenitis: case report and literature review.Mycobacterium abscessus is a rapidly growing mycobacterium found in soil and water throughout the world. disease in immunocompetent patients usually consists of localized skin and soft tissue infections. In contrast, disseminated disease is uncommon, usually presents with rash, and almost always occurs in an immunocompromised host. We describe an unusual case of disseminated M. abscessus infection manifesting as fever of unknown origin and intra-abdominal lymphadenitis, but without rash. Our patient responded well to amikacin and clarithromycin therapy. We also review the literature related to the diagnosis and management of this uncommon disease.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
5/19. Chronic cutaneous mycobacterium haemophilum infection acquired from coral injury.A 61-year-old previously healthy man developed chronic dermal granulomata in his right arm after receiving a coral injury in thailand. After 7 biopsies, infection caused by mycobacterium haemophilum was diagnosed. This case highlights the difficulty of isolating this fastidious organism in the laboratory and suggests that seawater or coral was the source of the infection.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
6/19. mycobacterium xenopi, a potential human pathogen.mycobacterium xenopi is infrequently recognized as a cause of pulmonary disease. During a 12-year survey (1978-89),. 108 strains of this Mycobacterium were isolated from 90 persons and 6 hot water samples. From 87 patients 89 occasional strains of M. xenopi were isolated, and 3 patients were diagnosed as having pulmonary mycobacteriosis caused by it. The treatment and the response in these three cases were variable, depending on clinical conditions and sensitivity to drugs. Most of the strains isolated came from patients hospitalized at the Barzilai Hospital, Ashkelon, therefore a local environmental contamination was suspected. The suspicion was confirmed by the isolation of this thermophile organism from the hot water samples of the above hospital.- - - - - - - - - - ranking = 2keywords = water (Clic here for more details about this article) |
7/19. mycobacterium xenopi infection after heart transplantation: an unreported pathogen.Mycobacterial infections are a well-known, potentially serious, albeit infrequent complication of solid-organ transplantation. nontuberculous mycobacteria generally account for less than 50% of all such isolates in this patient population. mycobacterium xenopi, an environmentally ubiquitous organism and common contaminant of hospital hot water systems, is a particularly uncommon isolate after transplantation and has never been reported in heart allograft recipients. We report the occurrence of cavitary M. xenopi infection in an immunocompromised heart transplant recipient in which all the diagnostic criteria of the American Thoracic Society were met. To our knowledge, this is the first such case in a heart transplant recipient described in the literature. Despite therapy, to which the isolates were sensitive in vitro, the patient developed extensive lung cavitation and nodules and succumbed 5 months later to allograft rejection, chronic allograft vasculopathy, and pneumonia.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
8/19. Cutaneous infection with rapidly-growing mycobacterial infection following heart transplant: a case report and review of the literature.nontuberculous mycobacteria are ubiquitous and infrequently cause disease in humans, most commonly in immunocompromised hosts. One type of nontuberculous mycobacteria is Mycobacterium abscessus. This rapidly growing mycobacterium is a soil or water saprophyte. It was previously classified as a subspecies of mycobacterium chelonae; however, current taxonomy now designates it as a separate species. Rapidly growing mycobacteria are resistant to the usual antituberculous drugs. This emphasizes the need for tissue diagnosis and obtaining specimens for culture and drug susceptibility testing. M abscessus has been reported to cause infection in renal transplant patients, but is less well described in cardiac transplant recipients. We report the case of a 65-year-old man who presented 5 years after transplantation for heart failure, with a 2-day history of progressive right lower extremity swelling and redness. He recalled no antecedent trauma and denied any unusual epidemiologic exposure. Medical history included diabetes with peripheral neuropathy and renal insufficiency, hypertension, and right-sided heart failure felt to be due to obstructive sleep apnea. A punch biopsy of the area grew M abscessus sensitive only to clarithromycin (MIC not reported), amikacin (30 microg/mL), and kanamycin (30 microg/mL). On subsequent clinic visits, the patient had decreased leg swelling and resolution of the papular lesions. Ten weeks into antimycobacterial therapy, the patient had an increase in creatinine to 4.9 mg/dL from a baseline of 2.0 with fluid overload necessitating discontinuation of aminoglycoside therapy. He completed 6 months of treatment with oral clarithromycin. We describe these findings and review the literature in this report.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
9/19. Urinary mycobacterium fortuitum infection.mycobacterium fortuitum, a common saprophyte usually found in water and soil, can also be isolated from sputum and gastric secretions of healthy carriers. Under certain conditions, significant clinical infections due to M. fortuitum do occur. urinary tract infections are rarely caused by atypical mycobacteria. This report describes a urinary tract infection caused by M. fortuitum in a 73-year-old patient treated with corticosteroids for bronchial asthma, who was successfully treated with ofloxacin.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
