“…Similar results were reported by EFSA, where the most frequently reported serovars in human salmonellosis were in agreement with those isolated in slaughter pigs (EFSA, 2011). These findings support the notion that pigs and pork contribute to Salmonella infection in humans, although it is acknowledged that foods from other animal species also play a role as a source of these infections in humans (Hugas et al, 2014).…”

“…Although the proportion of subspecies I serovars was the highest (34.6%), not one of them belonged to those most-frequently seen in humans in the European Union, where Salmonella Enteritidis, monophasic Salmonella Typhimurium, Salmonella Typhimurium, Salmonella Infantis, and Salmonella Stanley were the top five serovars associated with human illness in 2012. 30 In another recent investigation, 55 where reptile isolates belonging to the top 15 serovars found in humans were characterized, the presence of serovars common in poultry, such as Salmonella Kentucky, was reported. This might be a result of feeding contaminated raw meat to carnivore reptiles in their study.…”

Salmonellosis transmitted by pet reptiles is an increasing public health issue worldwide. The aim of this study was to investigate the prevalence of Salmonella strains from captive reptiles in Croatia. From November 2009 to November 2011 a total of 292 skin, pharyngeal, cloacal, and fecal samples from 200 apparently healthy reptiles were tested for Salmonella excretions by bacteriologic culture and serotyping. These 200 individual reptiles included 31 lizards, 79 chelonians, and 90 snakes belonging to private owners or housed at the Zagreb Zoo, Croatia. Salmonella was detected in a total of 13% of the animals, among them 48.4% lizards, 8.9% snakes, and 3.8% turtles. Representatives of five of the six Salmonella enterica subspecies were identified with the following proportions in the total number of isolates: Salmonella enterica enterica 34.6%, Salmonella enterica houtenae 23.1%, Salmonella enterica arizonae 23.1%, Salmonella enterica diarizonae 15.4%, and Salmonella enterica salamae 3.8%. The 14 different serovars isolated included several rarely occurring serovars such as Salmonella Apapa, Salmonella Halle, Salmonella Kisarawe, and Salmonella Potengi. These findings confirm that the prevalence of Salmonella is considerable in captive reptiles in Croatia, indicating that these animals may harbor serovars not commonly seen in veterinary or human microbiologic practice. This should be addressed in the prevention and diagnostics of human reptile-transmitted infections.

“…Thus, the bacteria can easily spread between birds within a flock because the infected birds might become intermittent or persistent healthy carriers. The prevalence of Salmonella in poultry populations is considered a main risk factor for the presence of the bacteria within table eggs and poultry meat (Hugas & Beloeil, 2014). Some zoonotic Salmonella enterica serovars are known to infect humans through contaminated food products of animal origin, and Salmonella enterica serovar Heidelberg (SH) has been implicated as an important causative agent linked to numerous human outbreaks, with invasive infections and even deaths (Foley et al, 2011).…”

Effects of cold stress andSalmonellaHeidelberg infection on bacterial load and immunity of chickens

We analysed the effects of cold stress (19 ± 1°C, 6 h /day, from the first to the seventh day of life) applied to specific pathogen free (SPF) chickens. On experimental Day 1 (ED1), chicks were divided into four groups: C (not infected and kept under thermoneutral condition); CS (not infected and cold stressed); PC (Salmonella Heidelberg (SH) infected and kept under thermoneutral condition) and PCS (SH infected and cold stressed). High concentrations of corticosterone were found in the cold stressed birds on ED7 and ED21, with a greater increase in birds of the PCS group. Stress or non-stressed SH-infected birds had high levels of norepinephrine on ED21. On ED21, an increased percentage and number of SH were found in birds of the PCS group. On ED7, a decrease in macrophages presenting MHCII, CD8 + and CD8 + γδ cells was observed in the chickens of the CS group. Decrease was observed in CD3 + cells in the birds of the PCS group and increase in macrophages presenting MHCII cells and of the CD4 + /CD8+ ratio in chickens of the CS group on ED21. There was a decrease in CD8 + γδ cells in birds of the CS group on ED21 and in the CD3 + and CD8 + cell numbers in chickens of the PCS group on ED21. Our results suggest that cold stress applied to chickens in the first 7 days of life increases both the hypothalamus pituitary adrenal axis and the sympathetic nervous system activities, leading to long-term immune cell dysfunction, thus allowing increased SH invasion and persistence within the birds' body.
