The research on the prevalence of gastrointestinal parasites of antelopes and goats has been conducted in and around the Kahuzi-Biega National Park. The method of collecting dung by hand coupled to that of the laboratory coprology analysis were used. The results of the study show that the antelope and the goat have in common as roundworms trichostrongylus, Nematoduris and flatworms, Fasciola gigantica (Trematodes) and as other worms, Coccidia. Gastrointestinal parasites in both sites (PNKB and around the PNKB).Trichostrongylus, are abundant in antelopes and goats, but Coccidia are abundant around the PNKB so in goats. Goats have a high prevalence of parasites for the same species found in the two sites namely trichostrongylus, (51.2%), Nematoduris (8.7%) and Coccidia (47.5%) against trichostrongylus, (47, 5%), Nematoduris (1.2%) and Coccidia (21.2%) in antelopes whereas for Fasciola gigantica, antelopes have a high parasite prevalence (26.2%) than goats (20%). The other prevalences of parasites in antelopes are distributed as follows 5% respectively for Gardia lamblia and Molineus, 1.2% respectively for Balatidium parcel, Monezia expensa, Cappilaria sp and Ascarus lumbricoides and 2., 5% Trichuris trichura. The parasite infestation rate in the two small ruminants (antelope and goat) is at least 10 parasitic elements counted on the slide of Molineus, Trichuris trichura, Ascarus lumbricoides, Cappilaria sp, Monezia expensa and Nematoduris while for Coccidia and tricostrongylus, is 10 to 100 parasitic elements counted on the blade. The infestation rate of gastrointestinal parasites is 10.1% in antelopes and 31.9% in goats. Goats around the PNKB are quite infested with trichostrongylus, as the antelopes at PNKB. For Coccidian parasites, goats around PNKB are infested in the same way as PNKB antelopes.

Zoonosis are not a recent problem in the history of humanity. Throughout history, humans have lived with animals and may have contracted diseases, either through direct contact with animals or through contaminated food or the environment. Zoonotic agents often cause fatal diseases, such as plague, rabies, anthrax, brucellosis and various bacterial infections. Regarding the healthiness of meat delivered for consumption in Bukavu, out of a total of 49 samples collected and analyzed, the average FMAT (Total Aerobic Mesophilic Flora or general contamination) is 155.5. 106, total coliforms are 101.106, faecal coliforms 132.106 and pathogens 133.106/g of meat sample. The meats are more contaminated by a bacterial microflora with high loads. They are therefore unfit for consumption because they can cause toxi-infections, zoonosis and other infectious diseases.

16 dogs (Canis familiaris) of local breed 12 males for castration, 4 females for the diagnosis of an unknown pathology were administered a combination of anesthetic agents which included medium drugs of Xylazine 1.49 mg / kg) for premedication. After 10 minutes the animal was injected with an average dose of ketamine 14.72 (mg / kg). The infusion route and the parameters were recorded every 10 minutes time intervals (heart rate, respiratory rates, oxygen saturation, temperature, color of the mucous membrane, reflexes, capillary replenishment, blood sugar level and carbon dioxide). At 29.9 minutes, the injection of Diazepam came through the vein to sedate the animal. The average heart rate of the individuals was 86.89 beats per minute that of all intervals was 88.06 beats per minute. Respiratory rate was 16.73 breaths per minute and the average of all intervals was 21.89 breaths per minute. The average temperature for all individuals was 37.13 0C and for all intervals were 36.90C. The average oxygen saturation for individuals was 91.57% that for all intervals was 91.96%. The carbon dioxide for individuals was 32.52 mmHg and for all intervals was 31.4 mmHg. Anesthesia in dogs for suppression of the pain, good muscle relaxation and anesthetic depth that can ensure the well-being of animals and the surgical procedure.
