“…The disease in pigs is of great prevalence and economic importance due to the substantial losses that can be caused in the porcine industry [8,33]. E. rhusiopathiae was isolated from pigs from almost all continents except Antarctica [186][187][188][189]. Therefore, swine erysipelas constitute a severe global problem [190].…”

The available data indicate that the human world population will constantly grow in the subsequent decades. This constant increase in the number of people on the Earth will lead to growth in food demand, especially in food of high nutritional value. Therefore, it is expected that the world livestock population will also increase. Such a phenomenon enhances the risk of transmitting pathogens to humans. As pig production is one of the most significant branches of the world’s livestock production, zoonoses of porcine origins seem to be of particular importance. Therefore, in this review, we aim to introduce the latest data concerning, among other things, epidemiology and available preventive measures to control the most significant porcine zoonoses of viral, bacterial, and parasitic origin.

“…However, several reports have shown antibodies that recognise ER in conventionally reared laying hens with no history of erysipelas [ 15,22 24 ], which suggests that ER or antigenically similar bacteria could be common in these chickens or in their environment. However, there are only a few reports of isolation of ER from clinically healthy chickens [ 25 27 ] and additionally there is a study that failed to isolate ER by culture methods in healthy laying hen flocks [ 18 ]. By whole-genome sequencing we have found (manuscript in preparation) that ER from laying hens affected by clinical erysipelas belong to all described [ 28 ] genetic clades except clade 1.…”

Outbreaks of erysipelas, a disease caused by infection with Erysipelothrix rhusiopathiae (ER), is a re-emerging problem in cage-free laying hen flocks. The source of ER infection in hens is usually unknown and serological evidence has also indicated the presence of ER or other antigenically related bacteria in healthy flocks. The aim of the present study was to evaluate sample collection, culture methods and DNA-based methodology to detect ER and other Erysipelotrichales in samples from healthy chickens and their environment. We used samples from a research facility with conventionally reared chickens with no history of erysipelas outbreaks where hens with high titres of IgY recognising ER previously have been observed. Microbial DNA was extracted from samples either directly or after pre-culture in nonselective or ER-selective medium. Real-time PCR was used for detection of Erysipelothrix spp. and high-throughput amplicon sequencing of 16S rRNA sequencing was used for detection of Erysipelotrichales. A pilot serological analysis of some Erysipelotrichales members with IgY from unvaccinated and ER-vaccinated high-biosecurity chickens, as well as conventionally reared chickens, was also performed. All samples were negative for ER, E. tonsillarum and E. piscisicarius by PCR analysis. However, 16S rRNA community profiling indicated the presence of several Erysipelotrichales genera in both environmental samples and chicken intestinal samples, including Erysipelothrix spp. that were detected in environmental samples. Sequences from Erysipelothrix spp. were most frequently detected in samples pre-cultured in ER-selective medium. At species level the presence of Erysipelothrix anatis and/or Erysipelothrix aquatica was indicated. Serological results indicated that IgY raised to ER showed some cross-reactivity with E. anatis. Hence, environmental samples pre-cultured in selective medium and analysis by 16S rRNA sequencing proved a useful method for detection of Erysipelotrichales, including Erysipelothrix spp., in chicken flocks. The observation of such bacteria in environmental samples offers a possible explanation for the observation of high antibody titres to ER in flocks without a history of clinical erysipelas.
