“…A similar seasonal pattern in microbial counts was also reported by Premila in residential dwellings in India [48], by Caballero et al in Mexico [49], Huang et al in Taiwan [50] and Awadh et al in Egypt [51]. In contrast to seasonal patterns observed in the present study, a study by Leppanen et al [52] in Finland, Haas et al [53] in Austria and Sitkowska et al [54] in Poland observed a rising count of microbes in the air from winter to spring and summer. The differences between observed patterns may be due to different geographic locations and climatic variability.…”

“…Especially, direct contact between veterinarians and diagnosed animals is associated with the risk of biological contamination. In veterinary practice, not only animals are sources of microorganism contamination, but also people or the components of the indoor environment (Sitkowska et al 2015).…”

The objective of the study was to characterize the mycological quality of air at animal veterinary practice in Krakow. Bioaerosol measurements were performed during the summer season of 2017. The samples of outdoor and indoor air at animal veterinary practice were collected using a 6-stage Andersen`s air sampler. The highest concentration of fungal aerosol was observed in the treatment room. The analysis showed various fungal contamination in different measuring points at different measuring times of the day. Based on the analysis of bioaerosol particle size distribution it was found that the largest "load" of fungi, isolated form the air, can reach (in the human respiratory tract) to the region of the throat, trachei and primary bronchi. The predominant fungi in indoor air was Penicillium spp. and Cladosporium cladosporoides. Fungi that can cause dermatophytoses have also been isolated from indoor air: Microsporum canis and Trichophyton verrucosum. The study confirmed that the animal veterinary practice can be a workplace related to exposure to microbial agents.

“…Для передачі інфекції потрібні три елементи: джерело патогенів, сприйнятливий організм та шлях передачі (Kukhtyn et al, 2017;Kozlovska et al, 2017;. Часто такі умови створюються у закритих приміщеннях, а особливо у ветеринарних клініках, оскільки забруднювачами повітря є біоаерозолі (Steneroden et al, 2010;Sitkowska et al, 2015). Біоаерозоль -це сукупність мертвих та живих патогенних і непатогенних мікроорганізмів, клітин епітелію, шерсть, волосся, частинки рослинного походження тощо, які завислі в повітрі (Harper et al, 2013;Feßler et al, 2018).…”

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