Engineering control of bacterial cellulose production using a genetic toolkit and a new cellulose-producing strain.

Bacterial cellulose is a strong and ultrapure form of cellulose produced naturally by several species of the Acetobacteraceae Its high strength, purity, and biocompatibility make it of great interest to materials science; however, precise control of its biosynthesis has remained a challenge for biotechnology. Here we isolate a strain of Komagataeibacter rhaeticus (K. rhaeticus iGEM) that can produce cellulose at high yields, grow in low-nitrogen conditions, and is highly resistant to toxic chemicals.

Microbiology of chronic suppurative otitis media in children in Surabaya, Indonesia.

The aerobic and anaerobic microbiology of 38 children from Surabaya, Indonesia, who suffered from chronic suppurative otitis media (CSOM) was studied using strict microbiological methodology. A total of 106 isolates (49 anaerobic and 57 aerobic) were recovered. Aerobic organisms alone were isolated from 11 (29%), anaerobic bacteria only in 4 (11%) and mixed aerobic and anaerobic flora were present in 23 (60%).

The predictive value of Phadiatop Paediatric in the determination of atopy in allergic diseases in children.

We obtained 28 patients with asthma bronchiale in this study. The presumptive diagnosis of allergy was made on the basis of history and physical examination. The positive result of the skin test to inhalant extracts and positive history of inhalant allergy add a confirmatory evidence in the diagnosis of inhalant allergy.

Acute mediastinitis.

Mediastinitis is not a new disease, however, the occurrence was rare especially in children. Focal infection, which considered to be insignificant, can result in diffuse dissemination involving mediastinum leading to fatal condition. This paper reported a case of mediastinitis with very critical condition.
