“…Various studies were carried out to isolate and serotype Salmonella from dairy cattle and calves (4,7,14,18,21,22,24). Several researchers (4,7,14,18,21,22,24) Fecal Salmonella studies in Turkey are usually based on slaughterhouse samples or case-based notices. Gökçen et al (26) isolated S. Typhimurium from the small bowel contents of only one cow out of 298 cattle.…”

IntroductionSalmonellosis is a common bacterial enteric infection with significant economic losses for the intensive production of cattle, sheep, and poultry (1,2). Salmonella species are zoonotic and are transmitted to humans via ingestion of contaminated milk, eggs, and meat (3,4). Although Salmonella infections may occur at any age in cattle, the associated clinical symptoms are more severe in calves from the first 2 weeks to 3 months of their life (5,6).Salmonella enterica subsp. enterica may cause infections associated with several clinical symptoms or systemic infections characterized by diarrhea and septicemia and may even lead to death in severe cases. It can be harbored by asymptomatic carriers (2,5). In the enteric form of salmonellosis, the stool is sticky and watery and has a putrid odor. It may contain flecks of mucus, shreds of the mucous membrane, and in some cases blood. Young calves and lambs frequently develop septicemia. Furthermore, marked depression, fever, symptoms of the central nervous system, pneumonia, and death within 2-3 days can also occur (7-9). Clinical symptoms and necropsy findings alone are not sufficient for a definitive diagnosis of Salmonella infection. It is imperative to isolate and identify the causative Salmonella species (10-12). While the isolation of Salmonella is relatively easy via bacterial culture from samples taken from animals with septicemia, carcasses, and the organs of aborted fetuses, enrichment is needed to increase the chance of isolating Salmonella from feed samples or from fecal cultures used to detect carriers (7,13,14).This study aimed to isolate and serotype Salmonella species from fecal samples of dairy cattle, calves with diarrhea, camels, and water buffaloes and to determine sensitivities of the isolates to antibiotics. Materials and methods SamplingA total of 869 fecal samples were collected from 21 herds in 13 provinces (Konya,

“…and E. coli, the most common resistance pattern was the TET-STR-AMP-COL pattern, reflecting the predominant use of these antibiotics in ruminants ( Table 2). Given the fact that the presence of pathogens in living ruminants indicates their presence in carcasses, it is desirable that ruminants reaching the slaughterhouse have a low number, orno pathogens (14, 17,20).…”

Background:The increasing prevalence of antimicrobial resistance bacteria in meat-producing animals, especially ruminants, represents a major problem for human and veterinary medicine and also could increase the patients' morbidity and mortality. Objectives: The current study aimed to identify the occurrence and antimicrobial susceptibility pattern of Salmonella spp. and Escherichia coli isolated from slaughtered ruminants in East-Azarbaijan province. Materials and Methods: In this study 160 samples (40 sheep, 40 goats and 80 cattle) were examined to isolate the enteric pathogens. The antibiotic resistance was determined by Kirby-Bauer disc diffusion method using 12 antibiotics. Results: A total of one hundred and twenty bacteria were obtained and most of these isolates belonged to these following genera: Escherichia coli (25%), Proteus (18.8%), Salmonella spp. (8.8 %), Pseudomonas spp. (7.5%) and Yersinia spp. (6.3%). Eight (57.1%) of 14 Salmonella spp. isolates and 26 (65%) of 40 E. coli isolates showed resistance to more than four antibiotics, called multiple antibiotic resistance (MAR). Conclusions: Overall, the obtained results emphasize the need for a surveillance and monitoring system to emerge drug resistance in all pathogenic microorganisms in ruminant and other animals.

“…Kagambega et al [4] reported Salmonella data in cattle from Burkina Faso, and Adabara et al [5] from hospital cases in Nigeria. Salmonella reports are available in Ethiopia on the prevalence of Salmonella in different food animals, such as cattle, sheep, goats and pigs [1,2,[6][7][8], camels [9], chickens [10] at abattoirs, from animal products at supermarkets [1,2,11], and from human cases [12,13]. Serotypes reported from Ethiopia include 48% each for S. Dublin and S. Mishmarhaemek, 20% for S. Typhimurium [8], 54% for S. Anatum, 19% for S. Newport [3], 38.8% for S. Saintpaul, and 22.4% for S. Braenderup [9].…”

Introduction: Salmonella has been reported from foods and the food production environment, with outbreaks occurring in the human population worldwide. Methodology: A survey on Salmonella in two beef production lines (a beef abattoir line and a processing line) in Addis Ababa, Ethiopia was conducted, with a total of 668 various samples randomly collected from animal-related materials, the environment, and a beef product (mortadella). Results: Overall, a 12.9% prevalence (26.3% from the abattoir line, 5.3% from the processing plant line) was observed. The prevalence in the abattoir line environment (36.6%) was higher than that in animal-related samples (14.7%); the reverse was true for the processing plant line. Out of 86 isolates, 10 serovars were identified, and 8 remained unidentified. The predominant serotypes were S. Saintpaul (32.5%), S. Muenchen (19.8%), and S. Larochelle (12.8%). S. Kastrup and S. London were isolated for the first time in Ethiopia. Conclusions: Data indicate open ports of entry for Salmonella, with possible transfer along the line. Further investigations from farm to fork are recommended in order to identify these positions of entry.
