| International studies and epidemiological data have revealed a strong association between salmonellosis and chicken meat. This association provides serious challenges for food safety and international trade. Microbiological Risk Assessment is a food safety tool that is used to determine the incidence of food borne illnesses. The procedure identifies a microbiological hazard in the entire food continuum (from farm to fork), and estimates the adverse effects to human health, of ingesting the microbial hazard. The Assessment integrates four steps, hazard identification, hazard characterisation, exposure assessment and risk characterisation, to produce a practical estimate of risk. In each step, knowledge of the prevalence and concentration of the pathogen,... |

| ABSTRACT Fowl paratyphoid infections are caused by different Salmonella serovars that can affect a wide range of hosts. Due to its complex epidemiology, Salmonella serovar identification is crucial for the development and implementation of monitoring and control programs in poultry farms. Moreover, the characterization of the antimicrobial resistance profiles of Salmonella strains isolated from livestock is relevant to public health because they are a common causative agent of foodborne diseases. The objective of this study was to investigate the presence of Salmonella spp. and to identify the antimicrobial resistance profiles of strains isolated in the midwestern region of São Paulo state, which accounts for the highest production of table eggs in Brazil.... |

| ABSTRACT: The present study aimed to describe and characterize, for the first time, two outbreaks of salmonellosis caused by Salmonella Ndolo in foals and calves in Brazil and compare the isolated strains with S. Ndolo previously identified in asymptomatic reptiles. The affected calves and foals presented fever, lethargy, and profuse diarrhea. Isolated strains were subjected to antimicrobial susceptibility testing, characterized according to virulence genes, and fingerprinted by ERIC-PCR. Salmonella Ndolo was identified in fecal samples from two foals and four calves. One isolate from a calf was resistant to amoxicillin/clavulanic acid, trimethoprim/sulfamethoxazole, and florfenicol. Strains from two other calves were resistant to oxytetracycline. All... |

| The clinical conditions of healthy calves infected with 10(9) CFU of Salmonella Typhimurium were evaluated and the viability of the experimental model in disease induction was verified. Twelve male Holstein calves, 10 to 15-days old, were examined. They were allocated into two groups, control and experimentally infected. Animals were submitted to clinical examination after inoculation and at every 24 hours, during six days after infection. Samples of rectal swabs were collected for Salmonella Typhimurium isolation. Results showed that all animals had different degrees of diarrhea, with mucus and bleeding, 24 to 72 hours after experimental infection with Salmonella Typhimurium, accompanied by fever, but no signs of sepsis. The isolation of Salmonella... |

| Salmonella enterica is frequently associated with outbreaks of human salmonellosis, and products of avian origin, such as eggs and chicken meat, are the main vehicles of its transmission. The present study describes the occurrence of different serovars of Salmonella enterica and phagotypes of S. enterica serovar Enteritidis in eggs destined for human consumption. Four thousand eggs obtained from commercial egg laying farms and one thousand discarded hatching eggs from broiler farms, which were acquired at farmers' markets and informal shops, were analyzed. Salmonella spp. was isolated from 52.0% of the discarded hatching eggs, in which the predominant serovar was Enteritidis (84.6%), and the predominant Salmonella Enteritidis phagotype (PT) was PT7... |

| Due to the constant evolution of industrial poultry production and the global emergence of bacterial resistance to antibiotics there has been an increasing interest in alternatives for the treatment of poultry salmonellosis, such as phage therapy and probiotics. The present study evaluated the effects of the oral administration of the bacteriophage P22 and of a probiotic, consisting of four Lactobacillus species, on the level of circulating heterophils containing a superoxide anion of one-day-old broilers challenged with Salmonella Typhimurium for seven days. It was concluded that the treatment with a probiotic with lactobacilli of broilers experimentally infected with Salmonella spp eliminates this pathogen by increasing the circulating levels of reactive... |

| The present study aimed at evaluating the effect of the prebiotic Bio Mos™ (2 kg/ton up to 10 days; 1 kg/ton from 10 to 21 days; and 0.5 kg/ton from 21 days to slaughter), of the probiotic Lac XCL 5x™ (by spray-mixing), of a combination of the two supplements (prebiotic + probiotic), and of one growth promoter antimicrobial agent (Avilamycin at 15 ppm). Birds were orally challenged with inoculated Salmonella Enteritidis (SE) 10(6) CFU at 3 days of age. Four hundred and eighty male Ross chicks were used. The experiment lasted 28 days, and the analyses were conducted at 15 and 28 days of age. Cecum and liver bacterial colonization of production of anti-SE antibiodies, intestinal micrometry and bird performance were assessed. Neither the prebiotic, nor the... |

| ABSTRACT This study reports a co-infection of Escherichia coli and Salmonella in a free-living ruddy ground dove (Columbina talpacoti) received at the Laboratory of Ornithological Studies of the State University of Ceará, Brazil. The bird presented diarrhea, leg paralysis and anorexia, and died shortly after. Necropsy was then performed and samples from lung, kidney, liver and intestine were collected for microbiological and histopathological analyses. Escherichia coli was isolated from cloacal swab, lung and kidney samples. Salmonella ser. Saintpaul was identified in liver and spleen samples. Escherichia coli isolates were tested for the presence of eight diagnostic genes for diarrheagenic pathotypes (STEC, ETEC, EPEC, EIEC, EAEC) with conventional... |

| The strain used in this work was a Salmonella enterica subsp enterica serovar Kottbus (6,8:e,h:1,5) isolated from imported day-old ducklings in Laboratório Nacional Agropecuário (LANAGRO/SP) of the Ministry of Agriculture of Brazil (MAPA). In view of the lack of information available about this Salmonella isolate and also because it was detected in day-old imported birds, this study was carried out to investigate the dissemination of S. Kottbus among newly hatched chicks. The birds were placed in three groups: one group of 20 birds received 0.1 mL of S. Kottbus culture containing 1.2 x 10(8) CFU/mL, the second group of 20 birds was inoculated with 1.2 x 10(5) CFU/mL and the third group of 10 birds was untreated (control group). Results were similar for... |

| ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were collected. The isolated strains were subjected to antimicrobial susceptibility test by disc-difusion method and were fingerprinted by ERIC-PCR. Macroscopic lesions suggestive of salmonellosis, such as fibrinonecrotic enteritis and hepatosplenomegaly were observed. Salmonellosis was confirmed by isolation of S. Typhimurium from stool samples and organs... |

| An experiment with 630 one-day-old chicks experimentally inoculated with Salmonella Typhimurium was performed to evaluate the effects of an organic acid blend (benzoic, fumaric and 2-hydroxi-4-methylltio-butanoic - HMTBa) on intestinal health and performance. The experimental challenge with Salmonella Typhimurium occurred in two different routes of administration: via crop on the first day after hatching, and via feed, offered from seven to 14 days of age. These groups were treated with organic acids in a 3 × 2 (agent versus acid) factorial arrangement. Chicks treated with organic acids had higher weight gain, mean live weight and better feed conversion at 14 days of age, and higher weight gain at 28 days of age. Chicks treated with organic acids... |

| The objective of this experiment was to evaluate the influence of lactulose on performance as well as its ability to prevent colonization by Salmonella Typhimurium in broilers orally inoculated with this pathogen. The design adopted was completely randomized, with 630 one-day-old male chicks distributed into six treatments, with seven replications and 15 birds per experimental unit. The treatments comprised the following procedures: T1 (control group) - no S. Typhimurium inoculation or supply of lactulosis; T2 - only inoculation of S. Typhimurium; T3 - only lactulosis supply; T4 supply of lactulosis and S. Typhimurium inoculation on the first day of life; T5 - supply of lactulosis 48 hours before S. Typhimurium inoculation; and T6 - supply of lactulosis 48... |

| Salmonella strains isolated from 1,138 samples representing 28,199 biological materials (stool, urine, blood and other fluids), collected between January 1985 and January 1999 at a reference University Hospital in Ribeirão Preto, São Paulo, Brazil, were studied. The most frequently detected serotypes were Salmonella enterica subspecies enterica serotype4,5,12:i:- (S. I 4,5,12:i:) (21.2%), S. agona (15.8%) and S. enteritidis (11.3%). A changing pattern of Salmonella serotypes was observed between 1985-1999. S. agona, which represented 27% of Salmonella serotypes isolated from 1985-1989, declined to 4% during the period from 1995 to 1999. S. enteritidis isolation remained below 1% until 1989; rose to 5.9% between 1990 and 1994, and increased to 32.3% between... |

| Several studies point out that eggs are the main cause of human salmonellosis, particularly when poorly processed or eaten raw. In addition of causing public health problems, the presence of Salmonella hinders international food trade, and therefore, it is a health barrier. There are several predisposing factors for the contamination of internal egg content by Salmonella spp, including eggshell quality, which is related to dietary calcium (Ca) and phosphorus (P) levels. In this study, eggs from Japanese quails fed diets containing two different Ca (2.0 or 3.5%) or P (0.25 or 0.45%) levels were evaluated. Three production phases were used in the experiment: starter, intermediate, and final. The presence of Salmonella Enteriditis in the eggshell and internal... |

| ABSTRACT: A 10-day old foal presented with a history of acute recumbency and generalized weakness, that progressed to seizure episodes and death. Post mortem examination revealed necrotizing and purulent omphalophlebitis and fibrinopurulent meningoencephalomyelitis. Salmonella Typhimurium was isolated from the central nervous system and determined to be the cause of the meningoencephalomyelitis. Due to the lack of evidence of gastrointestinal disease, the umbilical cord was considered the most likely portal of entry of the bacteria. The isolated S. Typhimurium was resistant to ampicillin and cephalotin, and partially resistant to enrofloxacin. These drugs are commonly used in the treatment of salmonellosis. This is the first report of S. Typhimurium... |

| Salmonellosis, a common human intestinal disorder primarily caused by contaminated meats and poultry, attacks an estimated two million Americans annually. Using a cost of illness approach, the medical costs and productivity losses alone were estimated to cost around one billion dollars in 1987. If pain and suffering, lost leisure time, and chronic disease costs could be quantified, the estimate would increase significantly. Other procedures for calculating the value of life could either raise or lower the estimated economic benefits of reducing human salmonellosis. Incorporating losses to farmers, whose animals have reduced feed efficiency, reduced weight gain, or deaths because of chronic salmonellosis, would also increase the estimates. Also excluded... |
