“…In addition, representatives of genera less frequently detected, for example, Brevibacterium, Corynebacterium, Mycobacterium, Tsukamurella, Actinomadura, Microbacterium, Rhodococcus and Propionibacterium were detected as well. The detection of species from these genera confirmed earlier investigations [5,38,42,57,58].…”

“…In this connection, Andersson et al [5] detected Mycobacteria and related genera as major colonizers of a wall in a children's day care centre with visible moisture damage. Torvinen et al [57] also described different potential pathogenic Mycobacteria isolated from water damaged building materials. Mycobacteria species are known to be responsible for different negative health effects, such as infections, inflammatory response, production of cytokines, NO and IL6 [ 16,21] and hypersensitivity pneumonitis [7,9].…”

Mould-colonized water damaged building materials are frequently eo-colonized by actinomycetes. Here, we report the results of the analyses of Actinobacteria on different wall materials from water damaged buildings obtained by both cultivation-dependent and cultivation-independent methods. Actinobacteria were detected in all but one of the investigated materials by both methods. The detected concentrations of Actinobacteria ranged between 1.8 x 10 4 and 7.6 x 10 7 CFU g-1 of investigated material. A total of265 isolates from 17 materials could be assigned to 31 different genera of the classActinobacteria on the basis of 165 rRNA gene sequence analyses. On the basis of the cultivation-independent approach, 165 rRNA gene inserts of 800 clones (50%) were assigned to 47 different genera. Representatives of the genera Streptomyces, Amycolatopsis, Nocardiopsis, Saccharopolyspora, Promicromonospora, and Pseudonocardia were found most frequently. The results derived from both methods indicated a high abundance and variety of Actinobacteria in water damaged buildings. Four bioaerosol samples were investigated by the cultivation-based approach in order to compare the communities of Actinobacteria in building material and associated air samples. A comparison of the detected genera of bioaerosol samples with those directly obtained from material samples resulted in a congruent finding of 9 of the overall 35 detected genera (25%), whereas four genera were only detected in bioaerosolsamples.

“…However, in most of these instances, water is proposed as a possible common vehicle of transmission. These bacteria have been isolated from treated drinking water (9,25,35), hospital and clinic water systems (44), water supplies in hemodialysis centers (6,16), and various other sites, including dental units (34), ice machines (15,24), swimming pool and hot tub water (12,19,27), metalworking fluid (28,36), and aerosols generated during the dismantling of moisture-damaged buildings (43). This group of mycobacteria is heterogeneous in terms of epidemiology, clinical disease spectrum, and drug susceptibility and is now considered a group of emerging waterborne pathogens.…”

Here we used a multigene sequencing approach for the identification and molecular typing of environmental mycobacteria of the fast-growing subgroup. Strains were isolated from hemodialysis water and clinical samples. Eleven type strains of related species of the genus were also included in this study. To gain further insight into the diversity of the environmental mycobacteria, we analyzed several housekeeping genes (16S rRNA, ITS1, gyrB, hsp65, recA, rpoB, and sodA). No individual phylogenetic tree allowed good discrimination of all of the species studied. However, a concatenated and a consensus analysis, combining the genes, allowed better discrimination of each strain to the species level, and the increase in sequence size also led to greater tree robustness. This approach is useful not only for the discrimination and identification of environmental mycobacteria but also for their molecular typing and studies of population genetics. Our results demonstrate high genetic diversity among the isolates obtained, which are probably new species of the genus.

“…Penempatan handuk yang tidak tepat seusai mandi dapat menyebabkan handuk semakin lembab, merupakan kondisi ideal yang memungkinkan M. leprae dapat hidup. 16,17 Pemakaian handuk yang tidak terpisah merupakan salah satu faktor higiene perorangan yang dapat memengaruhi penularan kusta. 4,6 Kebiasaan menjemur handuk di bawah terik mata hari dapat membunuh mikroorganisme yang tidak dapat bertahan hidup di bawah paparan sinar ultra violet, termasuk M. leprae.…”

Latar belakang. Faktor higiene perorangan yang baik merupakan faktor yang dapat mencegah penularan kusta. Penelitian terdahulu menunjukkan adanya hubungan antara higiene perorangan dengan kejadian kusta. Kasus kusta anak merupakan indikasi masih adanya penularan aktif di masyarakat. Tujuan. Menganalisis hubungan antara aspek higiene perorangan anak yang meliputi kebersihan badan dan rambut, kebersihan tempat tidur dan kebersihan handuk dengan kejadian kusta anak di Kabupaten Pasuruan tahun 2014-2015. Metode. Penelitian analitik observasional dengan desain kasus kontrol dilakukan selama bulan Maret-Juni 2016 dengan sampel kasus dan kontrol masing-masing 16 sampel di Kabupaten Pasuruan. Hasil. Kebersihan badan dan rambut anak yang kurang baik merupakan faktor risiko penularan kusta anak di Kabupaten Pasuruan tahun 2014-2015 (OR: 5,000; IK95% 1,096-22,820). Kebersihan handuk yang kurang baik merupakan faktor risiko penularan kusta anak tahun 2014 IK95% 1,227-110,953. Kebersihan tempat tidur bukan merupakan faktor risiko penularan kusta anak di Kabupaten Pasuruan tahun 2014. Sari Pediatri 201618(3):187-91 Kata kunci: kusta anak, higiene perorangan, faktor risiko
