The bacteriologically non-fit strain (ia50) was out-competed by the parental strain (ia31) and as a result its population decreased over time compared to the population of the parental strain. On the other hand, bacterial populations of the bacteriologically fit strain (ia66) and of the parental strain (ia31) were similar.

We performed an active impactor sampling method by using “hi-air” air sampler. The maximum growth of bacteria was observed in emergency wards.
Oligate (strict) anaerobic bacteria cannot grow in the presence of oxygen; therefore, in the laboratory, media containing reducing agents are used to cultivate anaerobes. Agents such as sodium thioglycollate and cystine remove much of the free oxygen present in liquid media.

The yield of immunoglobulins contained in the separated proteins is about twice as high as the value achieved by the prior art and their quality is superior. The intact physiologically active proteins obtained by this method contain all immunoglobulins that have high neutralization antibody titres against the seven serotypes of rotavirus.
