Bacteria of the genus Salmonella are gram-negative rods, facultative anaerobic non-spore formers, which may or may not be flagellated. These bacteria are frequently detected in poultry products and are important in animal and public health. The purpose of this study was to investigate the occurrence of Salmonella spp. in feces from broiler chicken litters located in municipalities of the central region of the state of Minas Gerais, Brazil. The study analyzed 845 feces samples from different poultry farms collected between September 2016 and March 2017. Pre-enrichment broths, specific selective broths and selective indicator agar were used for the analyses. The suspected isolates were submitted to biochemical testing and serotyping with “O” and “H” antisera to identify the Salmonella serotypes. The results showed that 213 feces samples were contaminated with Salmonella, and the serotypes found were: S. Minnesota, S. Sandiego, S. Schwarzengrund, S. Infantis, S. Hadar, S. enterica subsp. enterica (O: 4.5), S. Montevideo, S. Miami, S. Heidelberg, S. Cerro, S. Ndolo, S. Panama, S. Anatum, S. Tennessee, S. Agona, S. Newport and S. Muenster. The Minnesota serotype was predominant among the isolates investigated. Actions to improve the biosafety of commercial poultry farms are necessary to prevent possible contamination of poultry products that endanger human health.

Salmonella Phage

The exploration of novel nonantibiotic interventions in the field, such as the use of bacteriophages, is necessary to avoid the presence of Salmonella. Bacteriophages are a group of viruses widely distributed in nature, strictly associated with the prokaryotic cell. Researchers have demonstrated the success of phage therapy in reducing Salmonella counts in poultry products. However, the impact that phage concentration in the environment may have against certain Salmonella serovars is not well understood. Therefore, the aim of this study was to assess Salmonella phage prevalence in commercial poultry farms in terms of the production type: layers or broilers. The most prevalent Salmonella serovars isolated in poultry production were used for phage isolation. Salmonella specific phages were isolated from 141 layer and broiler farms located in the Valencia region during 2019. Analysis of the samples revealed that 100% presented Salmonella phages, the most prevalent being against serovar S. Enteritidis (93%), followed by S. Virchow (59%), S. Typhimurium (55%), S. Infantis (52%) and S. Ohio (51%). These results indicate that poultry farms could represent an important source of Salmonella phages. Nevertheless, further studies are needed to assess the epidemiology of phages against other serovars present in other countries and their diversity from the point of view of molecular studies.

Epidemiological Characterization

Background: Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In recent years, Brazilian poultry has gone through a scientific and technological evolution which resulted in high density poultry hens in the laying sheds and an increase of the occurrence of ectoparasites such as Diptera. The presence of these flies have caused negative impacts for poultry farming, since these may be responsible for the increase of stress and disease emergence and, in addition, reduction of productivity. In this context, the control of synanthropic Diptera is one of the challenges of the poultry farmers and professionals of this area. This study was carried to assess and characterize the risks for the presence of flies in chicken houses of laying farms in the state of Minas Gerais.Materials, Methods & Results: Was used a secondary database and adapted for this study, with information from 402 chicken houses of 42 laying hens commercial properties. The variables used to compose the correspondence model were selected through chi-square tests (P ≤ 0.05). A risk index was built to the presence of flies from variables considered as risk factors for these ectoparasites. In addition, a study of the spatial analysis was carried to evaluate the intensity of chicken houses of poultry farms with the presence of flies. For this, a Kernel map was produced using the QGIZ 2.18.1 software, georreferencing the regions of state of Minas Gerais that have these ectoparasites. It was observed the presence of flies in 253 chicken houses evaluated, which corresponds to a frequency of 62.9%, with the most present flies were Chrysomya spp. 37.3%, M. domestica 34.3%, Fannia spp. 16% and Stomoxys spp. 14%. The graph of the correspondence analysis produced for the epidemiological characterization of the presence of flies presented an accumulated chi-square value of 56.05%. There was an association of the risk index with removal interval and the humidity of the manure and with the type of installation of chicken houses. Farms with chicken houses that create their birds on the ground present a lower risk for the presence of Diptera. In addition, when the removal of the manure is performed manually and is not done periodically, the presence of flies in the chicken houses is observed. It was verified that clusters located in the messoregion south/southwest of Minas Gerais and between the west and metropolitan mesoregion of Belo Horizonte with chicken houses that have the presence of flies.Discussion: The accumulation and permanence of manure can occur in less technical farms that have laying hens kept in confinement with high densities. In the case of Diptera, the greater the interval of removal of the manure below cages, the greater the risk for their presence, combined with the high densities of the birds that contribute to a faster accumulation of manure. The humidity of the manure is another important factor for the development of flies. The risk is high when chicken feces are liquefied, due to the fact that larvaes of flies need a moist substrate for survival. These results provide knowledge about the epidemiology of flies, in addition to demonstrate the profile of laying farms in the state of Minas Gerais. The implementation of certain management measures and the investment in technification of the chicken houses could reduce the risks of possible infestations in the flocks, besides the negative effects resulting from this ectoparasitism.

The state of Pernambuco is the largest producer of eggs in the North and Northeast of Brazil and second one in the broiler production. Mycoplasmas are important avian pathogens, which cause respiratory and joint diseases that result in large economic losses. The aim of the present study was to investigate the occurrence of Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) in broilers and commercial laying hens in the state of Pernambuco, Brazil. Tracheal fragments were analyzed from 55 healthy broilers, 35 broilers with respiratory signs and 30 commercial laying hens with respiratory signs, from 24 commercial poultry farms, each sample was composed of a pool of five birds. The bacteriological exam, PCR and nested PCR were used for the detection of Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS). All samples were negative in bacteriological isolation. In the PCR analyses, seven samples from birds with respiratory signs were positive for MS and one was positive for MG, the latter of which was confirmed as the MG-F vaccine strain. The occurrence of MS in chickens with respiratory signs may indicate inadequate sanitary management on poultry farms, favoring the propagation of mycoplasmosis.

The Impact

Salmonella is a foodborne pathogen commonly associated with poultry products. The aims of this work were to 1) estimate the impact of critical steps of the slaughter process on Salmonella detection from broiler chicken carcasses in two commercial poultry slaughter plants in Quebec, Canada, 2) investigate the presence of the pathogen in the slaughter plant environment, 3) describe, using a high resolution melting (HRM) approach, the HRM Salmonella profiles and serotypes present on carcasses and in the slaughter plant environment and 4) evaluate if the HRM flock status after chilling could be predicted by the flock status at previous steps of the slaughter process, or by the status of previous flocks, or by the status of the processing environment, for a same HRM profile. Eight visits were conducted in each slaughter plant over a 6-month period. A total of 379 carcass rinsates from 79 flocks were collected at 5 critical steps of the slaughter process. Environmental samples were also collected from seven critical sites in each slaughter plant. The bleeding step was the most contaminated with >92% of positive carcasses. A decrease of the contamination along the slaughtering process was noted, with carcasses sampled after dry-air chilling showing ?2.5% Salmonella prevalence. The most frequently isolated serotypes were S. Heidelberg, S. Kentucky and S. Schwarzengrund. The detection of the S. Heidelberg 1-1-1 HRM profile on carcasses after chilling was significantly associated with its detection at previous steps of the slaughter process and in previously slaughtered flocks during a same sampling day. Results highlight the importance of the chilling step in the control of Salmonella on broiler chicken carcasses and the need to further describe and compare the competitive advantage of Salmonella serotypes to survive processing. The current study also illustrates the usefulness of HRM typing in investigating Salmonella contamination along the slaughter process.
