Prokaryotic microbiota of recycled paper mills with low or zero effluent
Charlotta Kanto Öqvist,Jukka Kurola,Jaakko Pakarinen,Jaakko Ekman,Satu Ikävalko,Jaakko Simell,Mirja Salkinoja-Salonen +6 more
TL;DR: The findings indicate that closing the water circuits strongly limited diversity of the microbiota but allowed efficient mineralization of the dissolved and suspended matter.

Contrasting immunological effects of two disparate dusts - preliminary observations.
Harri Alenius,Jaakko Pakarinen,Ossian Saris,Maria A. Andersson,Marina Leino,Kristiina Sirola,Marja-Leena Majuri,Jari Niemelä,Sampsa Matikainen,Henrik Wolff,Leena von Hertzen,Mika J. Mäkelä,Tari Haahtela,Mirja Salkinoja-Salonen +13 more
TL;DR: Contact to debris originating from human commensal bacteria in urban house dust elicited a Th2-type response whereas barn dust with high bacterial diversity directed the cells towards a Th1 response.

High genetic relatedness among Mycobacterium avium strains isolated from pigs and humans revealed by comparative IS1245 RFLP analysis.
TL;DR: Porcine and human isolates with RFLP patterns differing by only one or two bands were found, which shows that the same M. hominissuis strains may infect both humans and pigs, suggesting that pigs and humans share common environmental sources of infection.

Proliferation of mycobacteria in a piggery environment revealed by mycobacterium-specific real-time quantitative PCR and 16S rRNA sandwich hybridization.

TL;DR: It is shown, that mycobacteria occur in organic materials commonly used on pig farms, and may proliferate in bedding materials during use, and that DNA- and RNA-based methods may be utilized for detection of environmental reservoirs of myCobacteria causing porcine and human infection.

Comparative study of potential virulence factors in human pathogenic and saprophytic Trichoderma longibrachiatum strains.
Zsuzsanna Antal,László Kredics,Jaakko Pakarinen,Ilona Dóczi,Maria A. Andersson,Mirja Salkinoja-Salonen,László Manczinger,András Szekeres,Lóránt Hatvani,Cs. Vágvölgyi,Elisabeth Nagy +10 more
TL;DR: Metabolites of the strains inhibited the growth of different bacteria, furthermore, compounds produced by three clinical isolates reduced the motility of boar spermatozoa, indicating their toxicity to mammalian cells as well.
