چکیده
Exposure to bioaerosol from the premises of veterinary clinics poses a significant threat health staff and patient animals. Because pathogens airborne infections can be transmitted through it. The aim work was determine number mesophilic aerobic microorganisms in various during their operation under influence disinfection. Bioaerosol samples were collected using sedimentation method. seeded Petri dishes placed thermostat at an incubation temperature +37 ± 1 °C for 48 hours. It established that highest room primary examination, manipulation area with boxes keeping sick animals dental operating – 1943.5 127.1 2725.2 193.4 CFU/m3. That is, no excess bacteria found accordance conditional standard 5000 Although other these clinics, much lower ranged 102.4 8.3 123.1 9.5 rooms room, maximum (from 2801.3 178.2 1605.4 127.3 CFU/m3) winter period, 1.5 times higher, compared content summer period. Therefore, winter, “pressure” microbiota increases on animal patients, which turn lead transmission by droplets. During assessment preventive measures implemented it bioaerosol, detected 1193.5 107.4 1885.1 119.4 CFU/m3 after one-hour treatment bactericidal lamps, decreased 13.1–15.4 times. At same time, where microbial air pollution before disinfection within range 130.6 7.8−223.9 14.1 CFU/m3, exposure ultraviolet radiation, 3.7–4.7 all rooms, there remains stable part amount 30–150 per m3, not exposed effect lamps. determining risk spreading will make possible implement sanitary epidemiological reduce timely manner.

Thromboelastography (TEG) has been used in experimental animal studies since the early 1960s and in a routine clinical setting for the past decade. From the data currently available, it is clear that both the scope and limitations of TEG in animals resemble those observed in humans. TEG has been used to diagnose hypercoagulability in animals with disseminated intravascular coagulation, various ...
