AbstractWild house mice, naturally infected with Aspiculuris tetraptera were segregated according to their weight into six age groups. The prevalence of infection and the mean worm burden of these mice were studied in the different age groups. The overall prevalence of infection was high (57% or more) in all the groups except the youngest. Mice acquired larvae soon after weaning; the highest larval burdens were reached in juvenile mice and the highest mature worm burdens, a group later, in mature mice. Older mice had fewer larvae and fewer mature worms. The mature worm burdens decreased but relatively slower than the larval burdens. It is suggested that either innate or acquired resistance could account for these observations.

The article refers to the research work carried out in recent years at the poultry farms of the Khachmaz region of the Republic of Azerbaijan, the influence of opportunistic microbes on the activities of the farm. The role of opportunistic microbes in the occurrence of certain diseases with deficiencies in the process of feeding and raising of birds, and the microclimate in poultry farms is shown. During the bacteriological examination of breeding eggs by seasons there were revealed the presence of infection in the winter season with E. coli, Salmonella, Staphylococcus and Streptococcus – with each infection separately 13.0 %, in the spring season with E. coli, Salmonella, Staphylococcus – with each infection separately 20.0 %, in the autumn period with E. coli 27.0%, Salmonella 40.0 %, Staphylococcus 13.0 % and Streptococcus 13.0 %. In the course of bacteriological examination of dead embryos, the presence of infection in the winter period with E. coli 20.0 %, salmonella 30.0 %, staphylococcus 25.0 % and streptococcus 25.0 %, in the spring  season with E. coli 30.0 %, salmonella 40.0 %, staphylococcus 15.0 % and streptococcus 15.0 %, in the autumn season with E. coli 45.0 %, salmonella 55.0 % was revealed. In the autumn period, infection with staphylococci and streptococci was not detected. When studying as a whole, pseudomoniasis and mold fungi were not found.
