In the course of the study permeability of intestinal mucosa of chickens suffering from eimeriosis while treating them with various veterinary drugs, including probiotics, was evaluated. The simulation of a typical clinical picture of eimeriosis was carried out by oral administration of suspension with coccidial oocysts (1.6 × 105/head) using a probe. To create different forms and different intensity of inflammatory processes, chickens that received various anticoccidial preparations and probiotic strain Bacillus subtilis were infected with eimeria. According to the data from an autopsy, it was found that the use of a spore probiotic based on Bacillus subtilis and anticoccidial drugs containing robenidine hydrochloride and salinomycin had a positive protective effect when treating chickens from eimeriosis. A similar picture was observed when assessing permeability of intestinal mucosa as affected by bacteriophage, whereby permeability decreased with the use of probiotics and the above-mentioned active agents. In general, the decrease in productivity was significant in all groups. However, the effect of spore-based probiotics was quite pronounced against the background of eimeria polyresistance. In the situation where anticoccidial drugs are less effective, the use of a spore-based probiotic can have a noticeable protective effect. The effect of all anticoccidial drugs under study on the concentration of oocysts and the state of the mucosa was insignificant, which indicated polyresistance of different types of eimeria isolated from biological material to these drugs. The analysis of the intestinal mucosa integrity, based on the study of mucosa permeability to bacteriophages and a Johnson and Reid scoring procedure showed that a spore probiotic based on B. subtilis and anticoccidial drugs containing robenidine and salinomycin had the best protective effect against eimeriosis caused by field isolates of eimeria. When treating chickens suffering from eimeriosis caused by polyresistant forms of E. acervulina and E. tenella, it is advisable to use probiotics alongside with drugs based on robenidine and salinomycin.

Thermal inactivation kinetics of Bacillus subtilis α-amylase (BSA) in different environmental conditions was studied by performing isothermal experiments. As a response property, residual enzymic activity and residual heat of enzyme deterioration were chosen. A comparison of processing values determined from the read-out of a system with actual integrated processing values revealed the potentials of these systems as time-temperature integrators to be used in the pasteurization domain (temperatures of 70 to 100°C) for target attributes with z-values ranging from 6 to l2°C.

ABSTRACT Impact-induced ejections of rocks from planetary surfaces are frequent events in the early history of the terrestrial planets and have been considered as a possible first step in the potential interplanetary transfer of microorganisms. Spores of Bacillus subtilis were used as a model system to study the effects of a simulated impact-caused ejection on rock-colonizing microorganisms using a high-explosive plane wave setup. Embedded in different types of rock material, spores were subjected to extremely high shock pressures (5 to 50 GPa) lasting for fractions of microseconds to seconds. Nearly exponential pressure response curves were obtained for spore survival and linear dependency for the induction of sporulation-defective mutants. Spores of strains defective in major small, acid-soluble spore proteins (SASP) (α/β-type SASP) that largely protect the spore DNA and spores of strains deficient in nonhomologous-end-joining DNA repair were significantly more sensitive to the applied shock pressure than were wild-type spores. These results indicate that DNA may be the sensitive target of spores exposed to ultrahigh shock pressures. To assess the nature of the critical physical parameter responsible for spore inactivation by ultrahigh shock pressures, the resulting peak temperature was varied by lowering the preshock temperature, changing the rock composition and porosity, or increasing the water content of the samples. Increased peak temperatures led to increased spore inactivation and reduced mutation rates. The data suggested that besides the potential mechanical stress exerted by the shock pressure, the accompanying high peak temperatures were a critical stress parameter that spores had to cope with.
