“…(Chousalkar and Gole 2016). The infected animals, especially poultry and pigs, often do not show signs of disease (Nirmala et al 2018) and are therefore, a major cause of disseminating the infection to other herd members and possibly to other humans and animals. According to CDC, poultry is the most common single food source associated with Salmonellosis in humans (Fig.…”

“…Salmonellosis in birds is distributed throughout the world, is considered one of the most important zoonoses and results in severe economic losses due to high mortality, low productivity, high medication costs, worsening quality and large expenses in its eradication and control. These infections are caused by several different serovars and typically do not cause any clinical symptoms in birds (ANSARI et al, 2017;NIRMALA et al, 2018).…”

Salmonellosis is a zoonotic disease that affects commercial birds and causes major economic and productivity losses in the poultry sector. Belonging to the Enterobacteriaceae family, the Gram-negative bacillus of the genus Salmonella has presented itself as a health problem in recent years, as there has been a considerable increase in bacterial resistance, due to the indiscriminate use of antimicrobials as growth promoters. Given this context, bioactives from Brazilian flora, considered one of the most abundant in biodiversity, emerge as an alternative to the use of synthetic products. Thus, this work aimed to determine the chemical compounds of the native species Cinnamomum amoenum (Ness) Kosterm, as well as evaluate the antimicrobial activity of aqueous, ethyl acetate, hexane and ethanolic extracts against different serovars of the genus Salmonella. To obtain the extracts, the plant leaves were dried at 40°C and ground in a knife mill. Subsequently, sterilized by vacuum filtration and roto-evaporated, to completely remove the solvent. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (CBM) were performed using the broth microdilution method, with serial concentrations ranging from 200-0.09 mg/mL of the extract. As a positive control, gentamicin was used at a concentration of 200 mg/mL. Phytochemical tests revealed the presence of flavonoids, steroids and tannins, the latter present only in the aqueous and ethanolic extracts. Regarding antimicrobial activity, the ethanolic, hexane and ethyl acetate extracts showed inhibitory/bactericidal activity for all tested serotypes and the aqueous extract showed no activity on the tested serotypes. The ethanolic extract and ethyl acetate presented MIC ranging between 25 and 50 mg/mL and MBC ranging between 50 and 100 mg/mL. The hexane extract presented MIC ranging between 50 and 100 mg/mL and MBC with 100 mg/mL. The most susceptible serotypes for the ethyl acetate extract were S. Newport, S. Gallinarum, S. Montevideo, while for the ethanolic extract the most susceptible serotypes were S. Typhimurium, S. Mbandaka, S. Infantis, S. Heidelberg and S. Enteritidis. The results suggest that C. amoenum extracts have antimicrobial potential and could be a viable alternative to be used in poultry farms, thus being a more sustainable and less harmful approach to the consumer, who will be free from overdoses of synthetic antimicrobials that are commonly used. Furthermore, it is essential that new studies regarding the biological activities of C. amoenum are carried out, in order to validate its use in the control of poultry Salmonella.

“…Salmonella Enteritidis normally inhabits the intestinal tract of birds, excreted in feces for months, and transmitted by insect, rodent, equipment, human being, soil, air, and water [8,9]. Once infection stabilized in a productive flock, it can transmit vertically and horizontally to infect other farms easily with zoonotic Available at www.veterinaryworld.org/Vol.13/April-2020/3.pdf potential, especially Salmonella Typhimurium and S. Enteritidis [10]. The environment can act as a source of infection for salmonellosis, as Salmonella spp.…”

Background and Aim: Biosecurity practices are a must in broiler farms to reduce the risk of infectious agents. This study aimed to evaluate biosecurity measures in nine broiler farms in the Suez Canal area – Egypt with measuring the seasonal prevalence of salmonellosis. Materials and Methods: A cross-sectional study was conducted on randomly selected nine broiler farms of different housing systems based on the ventilation methods from March 2018 to April 2019. A total of 12,600 samples (6480 environmental, 4320 non-environmental, 1080 sera, and 720 live birds) were collected during four successive seasons. Results: Highly significant increases (p<0.01) were recorded in body weight gains in opened and closed-houses during summer; in food conversion ratios in opened-houses during winter and in closed-houses during winter and fall; in performance indices in opened-houses during summer and closed-houses during winter; and in live body weights, carcasses weights, liver, spleen, and bursa's weights in opened-houses during spring and in closed-houses during fall. Highly significant increases (p<0.01) were recorded in total bacterial, Enterobacteriaceae, and Salmonella counts in opened-houses during spring and in closed-houses during summer, in Salmonella Typhi O and H, and Salmonella Paratyphi A and B sera titer in opened-houses during summer and closed-houses during fall. Biosecurity measures scored 34 out of 43 with an average salmonellosis prevalence of 6.0% in closed-house and 24 out of 43 with an average salmonellosis prevalence of 24.67% in opened-house broiler farms. Conclusion: Weak biosecurity measures in broiler houses (opened and closed) were not sufficient to prevent the entrance and multiplication of Salmonella spp. Disciplines, commitment, and regulations of biosecurity need to be enforced in broiler houses to prevent the introduction and spread of diseases.
