“…absolute heterophil counts were not significantly different, whereas they were significantly (P < 0.05) higher than the value obtained during pre-infection. The heterophilic leukocytosis (neutrophilia) observed in the current investigation matches reports of neutrophilia observed by Sharma et al (16) in goats infected with Salmonella enterica serovar typhimurium.…”

“…In an earlier investigation by Kokosharov, intravenous injection of Salmonella typhimurium endotoxin into cockerels (10) produced hypochromic anemia, leukocytosis and increased phagocytic activities of the leukocytes. The relative increases in PCV and Hb observed in this investigation were attributable to Salmonella Paratyphi A, contrarily to Sharma et al (16) who observed a decrease in PCV and in the total erythrocyte count in goats infected with Salmonella enterica serovar typhimurium. The observed differences in response to the Salmonella infection may be due to the physiology of chicken erythrocytes, which are immature-nucleated, while in goats they are non-nucleated.…”

Une analyse hématologique a été effectuée sur 25 poulettes infectées expérimentalement par voie orale avec 0,5 mL de 1 x 107 CFU/mL de Salmonella Paratyphi A. Quatre jours après l’infection (p.i.), les animaux ont présenté de l’apathie, un plumage ébouriffé, de la somnolence, des diarrhées vert jaunâtre, une baisse de la prise d’eau et d’aliments. Les paramètres hématologiques des volailles ont été enregistrés aux jours 7, 14 et 21 p.i. Les valeurs ont été analysées avec le test de comparaisons multiples de Duncan, avec P < 0,05. L’hématocrite a été significativement plus élevé au jour 7 que lors de la pré-infection et qu’au jour 21 p.i. Il a cependant été semblable aux jours 7 et 14 p.i. De même, les concentrations d’hémoglobine chez les volailles ont été semblables lors de la pré-infection et aux jours 14 et 21 p.i. Elles ont été significativement plus élevées au jour 7 que lors de la pré-infection et qu’au jour 21 p.i. Les indicateurs d’anémie n’ont pas révélé de différences significatives entre les valeurs pré-infection et post-infection. La période a coïncidé avec celle de la baisse de prise d’eau et d’aliments lors de l’évolution de la pathologie. Il n’y a pas eu de différences significatives dans le nombre de leucocytes total aux jours 7, 14 et 21 p.i., mais ce nombre a été significativement (P < 0,05) plus bas lors de la pré-infection qu’aux jours 7, 14 et 21 p.i. L’évolution de l’infection à Salmonella Paratyphi A dépend de la dose infectante du micro-organisme. Les poulettes n’ont pas manifesté d’anémie ; la leucocytose pouvait être attribuée à la leucocytose hétérophile, à la lymphocytose, à la monocytose et à l’éosinophilie, qui sont des indicateurs d’infection aiguë et de stress interne auxquels les poulettes ont répondu de façon satisfaisante.

“…Acute enteric salmonellosis is common in adult sheep, leading to fever, anorexia, depression, and diarrhea, while septicemia is common in young animals [79,80]. However, asymptomatic carriage, chronic gastro-enteritis, and abortion have also been described [80,81].…”

Non-typhoidal Salmonella represents an important human and animal pathogen world-wide. Most human salmonellosis cases are foodborne, but each year infections are also acquired through direct or indirect animal contact in homes, veterinary clinics, zoological gardens, farm environments or other public, professional or private settings. Clinically affected animals may exhibit a higher prevalence of shedding than apparently healthy animals, but both can shed Salmonella over long periods of time. In addition, environmental contamination and indirect transmission through contaminated food and water may complicate control efforts. The public health risk varies by animal species, age group, husbandry practice and health status, and certain human subpopulations are at a heightened risk of infection due to biological or behavioral risk factors. Some serotypes such as Salmonella Dublin are adapted to individual host species, while others, for instance Salmonella Typhimurium, readily infect a broad range of host species, but the potential implications for human health are currently unclear. Basic hygiene practices and the implementation of scientifically based management strategies can efficiently mitigate the risks associated with animal contacts. However, the general public is frequently unaware of the specific disease risks involved, and high-risk behaviors are common. Here we describe the epidemiology and serotype distribution of Salmonella in a variety of host species. In addition, we review our current understanding of the public health risks associated with different types of contacts between humans and animals in public, professional or private settings, and, where appropriate, discuss potential risk mitigation strategies.

“…However, the prevalence in goats was higher than prevalence reported by Wassie (2004) in Addis Ababa abattoir, which was 3%, Zubair and Ibrahim (2012), 2% from Zakho abattoir, Kurdistan region, Iraq, and Bedaso et al (2015) who reported 0.54% from apparently healthy goats and sheep at Addis Ababa abattoir enterprise, Ethiopia. Similarly Sharma et al (2001) had also reported prevalence of 2.3% from goats samples in Zambia. Even though, the current prevalence was higher than what was discussed, it was also lower than that in Ferede et al (2015) in which it has 17.7% was reported from apparently healthy goats at Dire Dawa municipal abattoir, and 16.7% prevalence reported from goats slaughtered at Elfora abattoir in Ethiopia (Woldemariam, 2003).…”

A cross-sectional study was conducted between November 2015 and March 2016 on apparently healthy slaughtered sheep and goats, and clean knife at Luna and Elfora export abattoirs located at Modjo and Bishoftu towns to estimate the prevalence of Salmonella in sheep and goats, to assess the hygienic condition of flaying knife, and to isolate and identify the prevalent Salmonella sub-species. A total of 525 samples consisting of cecum (n=122), liver (n=122), mesenteric lymph nodes (n=122), abdominal muscle (n=122) from 44 sheep and 78 goats and 37 pooled knife samples were collected. The samples were examined for the presence of Salmonella following the conventional techniques of ISO standard and using OMNILOG bacterial identification system, GEN III microplate for confirmation and sub species identification. From the total of 122 animals examined, 21 (17.21%) were positive of which 12 (9.83%) were sheep and 9 (7.38%) were goats, and none of the samples from pooled knife swabs were positive for Salmonella. Statistically significant difference (P=0.04) in the prevalence of Salmonella was observed between the two species. The frequency of isolation was 10 (3.89%) and 11 (4.10%) from Luna and Elfora abattoirs, respectively. As a result, there was no significant difference (P =0.884) in the prevalence of Salmonella isolation between the two abattoirs. Of the total 488 tissue samples examined from apparently healthy slaughtered sheep and goat, 21 (4.3%) samples were Salmonella positive. Salmonella was isolated from 6.56% mesenteric lymph nodes, 5.73% cecum, 4.09% liver and 0.82% abdominal muscle samples. However, there was no significant difference between tissues (P=0.13). From the 21 isolated Salmonella species, 20 of them were confirmed to be the pathogenic Salmonella enterica subspp. enterica and 1 isolate was the non-pathogenic Salmonella enterica subspp. salamae. The results of this study showed the potential risk of sheep and goats as sources of pathogen for humans in the study area. These findings stressed the need for implementation of preventing close contact of offal and carcass during evisceration.
