Population control has become a major problem in many wildlife species. Sterility control through contraception has been proposed as a method for reducing population size. In this paper, the single species with sterility control and feedback controls is considered. Sufficient conditions are obtained for the permanence and extinction of the system. The results show that the feedback controls do not influence the permanence of the species.

Abstract: In March 2016, the microbiology laboratory of the Faculty of Veterinary Medicine in Cluj-Napoca, 3 type of antisalmonella vaccine for sheep were prepared. For type 1, 24 hours salmonella on brain heart infusion (BHI) broth culture, heat inactivated for 1 hour at 60°C, then with formaldehyde in a concentration of 3 ‰. Variant 2 - the culture supernatant obtained on solid BHI medium, washed with PBS, frozen-thawed 6 times, centrifuged at 4000 rpm for 15 minutes, filtered through 0.2 μm Millipore filter Orange Scientific. Variant 3 - suspension of cell walls remaining after centrifugation suspended in PBS and inactivated with formaldehyde.After the bacterial and fungal sterility control, the three types of vaccine were administered in rabbits by the subcutaneous route at a dose of 1 ml/individual along with 1 ml of plant extract adjuvant (decoction of Ewernia prunastri) sterilized by filtration.There have been two booster inoculations of the initial administration, 7 and 14 days after. Before each dose of vaccine, blood was sampled from the marginal auricular vein in order to control the immunogenicity by anti-somatic ˮOˮ serum antibody (Ab) titration using slow microplate agglutination test (Widal reaction). After three inoculations with the vaccine variant 1, Ab serum titer reached 1/128, and in types 2 and 3, 1/512 after 2 inoculations, decreasing to 1/256 after the second booster administered with no immunomodulator.

The aim of this work is to review the most important topics about the antiophidic sera sterility, including obtaining methods, sterilization procedures and clean room control using Vital Brazil Institute (VBI) as an example. Bibliographical research was performed through Medline, Lilacs, PubMed, ISI and the Fundação Oswaldo Cruz - RJ and VBI Libraries, from 1960 to 2009. The antiophidic sera for human use are immunobiologic products produced in Brazil by three national laboratories, including VBI. Due to the parenteral use, these products should be sterile and pyrogen-free, which demands the microbiological control during the whole fabrication process. The sterility and pyrogen tests are important steps to ensure the quality and safety of these immunobiological products. Thus, these tests are target for continue evaluation and improvement. The most interfering aspects in the consistency and analytical patterns include the proper method selection, sampling, culture conditions and validation criteria. As the national and international legal requirements are cautious with the assays validation and approval of sterile parenteral products; the intrinsic limitations for established assays still require more investigation aiming the continue improvement of the microorganism and contaminants detection methods and optimization of the analysis extent.
