Special Issue Information

Dear Colleagues,

Salmonella is a peculiar microorganism, consisting in several serovars that, despite common characteristics, show phenotypic and genotypic differences that impact epidemiology features and then control strategies. Some Salmonella serovars, as zoonotic agents, are of particular interest for public health consequences, and some others because of their impact on animal health. Regardless, the inevitable change of the characteristics and epidemiology of Salmonella means that a constant study of this heterogeneous microorganism is needed in order to adapt and/or identify the most effective control strategies in animal production.

We are pleased to invite you to contribute to this Special Issue, which aims to provide an advancement in Salmonella knowledge, with a particular focus on the mechanisms of transmission and persistence in livestock production animals and on feasible control strategies, particularly at the primary production level.

In this Special Issue, original research articles, including brief/case reports and reviews, are welcome. Research areas dealing with the epidemiology of Salmonella serovars with public health and animal health significance may include but not be limited to the following: horizontal and vertical transmission mechanisms, phenotypic and genotypic characteristics affecting Salmonella persistence at the primary production level, risk factors for Salmonella transmission and persistence at the primary production level, and control options at the primary production level.

We look forward to receiving your contributions.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs).

Feed-associated Salmonella serovars continue to be reported in poultry flocks. A study was conducted to investigate Salmonella contamination in major commercial feed mills that produce rations for broiler chickens within Great Britain. Dust and large moist gauze swab samples (12,791) were collected from 22 feed mills on 31 visits. Salmonella was isolated from 20 mills, with 15 mills (75%) having fewer than 5% Salmonella-positive samples. Fifty-one Salmonella serovars were isolated, with a large proportion of isolates being Salmonella (S.) Kedougou (29.4%) or S. 13,23:i:- (21.4%). European Union-regulated Salmonella serovars (Enteritidis, Infantis, Typhimurium and its monophasic variants) were isolated from 12 mills, mostly from non-processing areas, accounting for 40 isolates (4.4% of all Salmonella-positive samples). Fifteen Salmonella serovars were only isolated once. In terms of individual sampling locations within the mill, the waste handling locations were significantly more likely to be Salmonella-positive than some other mill locations. When sampling locations were grouped, samples collected from finished product areas were significantly less likely to be Salmonella-positive for Salmonella than some other mill areas. In conclusion, this study found that most mills producing broiler rations showed low-level Salmonella contamination. Full article
