Autores: Borsoi,A; Santos,LR; Diniz,GS; C. Salle,CTP; Moraes,HLS; Nascimento,VP.
Salmonellosis is an important disease with economic impact as it may affect animal performance and may result in foodborne disease in humans through the eggs and carcass contamination. Regarding the Salmonella control, it is possible to decrease its fecal excretion and the contamination of chicken carcasses by adding organic acids to the feed or drinking water at appropriate times. The aim of this study was to test a blend of organic acids and essential oils in broilers challenged with Salmonella Enteritidis (SE), and to verify the fecal excretion of Salmonella. Sixty broilers were placed in four groups. One group was the negative control. Another group was orally inoculated at 1 day-old with 10(5) CFU/mL of SE as a positive SE control. Two groups (T3 and...

Autores: Okamoto,AS; Andreatti Filho,RL; Rocha,TS; Menconi,A; Marietto-Gonçalves,GA.
The expansion of global poultry production has increased the need to reduce or control the agents responsible for economic losses, including Salmonella spp. These bacteria are also of public health concern due to their potential to cause food poisoning, and, more recently, due to the antimicrobial resistance presented by these bacteria. Molecular biology is an important tool currently used in the diagnosis and research studies of main poultry diseases. The present studied analyzed 100 samples of Salmonella Enteritidis (SE) isolated from avian material aiming at detecting the class 1 integron gene, Integroninvolved in antimicrobial resistance, by means of polymerase chain reaction (PCR), and comparing it with plate inhibition test. Subsequently, SE samples...

Organic acids and/or compound with defined microorganisms to control Salmonella enterica serovar Enteritidis experimental infection in chickens
Provedor de dados: 89
Autores: Sterzo,EV; Paiva,JB; Mesquita,AL; Freitas Neto,OC; Berchieri Jr,A.
The association of human foodborne salmonellosis with poultry products enhanced the efforts to control Salmonella Enteritidis in poultry farms. Dietary organic acid supplementation is one of the measures currently used to reduce the presence of undesirable microorganisms. Another method to control enteric Salmonella in poultry is competitive exclusion using defined or undefined microorganisms products. Organic acids and microbiological methods to accelerate the development of the intestinal microbiota can be used individually or in combination. The present study evaluated the effect of dietary supplementation of an acidifier and of a defined multi-strain microbial mixture (Biomin® PoultryStar) via drinking water in the control of the intestinal...

Genomic variants of bacteriophages against Salmonella enterica serovar Enteritidis with potential application in the poultry industry
Provedor de dados: 89
Autores: Robeson,J; Retamales,J; Borie,C.
Salmonella enterica serovar Enteritidis (SE) is a prevalent gastrointestinal pathogen worldwide, threatening both animal and human health. In the latter, disease is associated to the consumption of SE-contaminated products from the poultry industry. The control of SE infection is largely based on the use of antibiotics and vaccines, but the use of lytic bacteriophages is re-emerging as an additional strategy for SE control. In fact, a number of recent reports point to the adequacy of bacteriophage as an efficient prophylactic or therapeutic countermeasure to SE infections. However, less attention has been focused on the basic biology of these bacteriophages. Here we report on three bacteriophages (f18, IF1 and EST2) that share a common viral particle...

Provedor de dados: 89
Autores: Coelho,LR; Melo,RT; Monteiro,GP; Reischak,D; Mendonça,AO; Tavares,AAS; Rossi,DA.
ABSTRACT The analysis of Salmonella in the feces and the birds’ environment is a way of monitoring the colonization in the flocks and verifying the need for the introduction of stricter controls, in such a way that the results of the tests should be known before being sent for slaughter. The polymerase chain reaction (PCR), as well as other rapid methods represent alternatives increasingly used to detect enteric pathogens, but they need proof of effectiveness for their wide use. The aim of this study was to evaluate the equivalence between the results obtained by the methods: real-time PCR (BAX® System), Modified Rappaport-Vassiliadis Semi-solid Medium (MSRV) (ISO 6579) and the traditional method of official reference in Brazil for research of S....

Provedor de dados: 89
Autores: Sterzo,EV; Paiva,JB; Penha Filho,RAC; Berchieri Junior,A.
Competitive exclusion (CE) has been designed to accelerate the colonization of the alimentary tract of young commercial birds and it has been also used to repopulate the digestive tract after antibiotic therapy. The method has been successfully adopted as a means to prevent enteric salmonellosis. The present study was carried out to evaluate if CE is able to prevent this kind of infection. Newly hatched chicks were given a CE culture and at different intervals of time birds infected with Salmonella Enteritidis were placed together with the group of treated birds. CE culture was prepared from feces of adult laying hens incubated overnight at 37C under aerobic conditions. Birds were killed 4 and 8 days after challenge and viable counts of Salmonella...

Two groups of domestic pigeons (Columba livia) were experimentally infected orally with doses of 9.5 x10(7) and 9.5 x10(9) CFU/mL (group A and B, respectively) of a Salmonella Enteritidis (SE) strain isolated from chickens. None of the used doses caused mortality of the inoculated birds; however, the pathogen was successfully recovered from the liver and spleen of group B birds on day 7 post-inoculation (dpi). Pathogen shedding, as evaluated through cloacal swabs, occurred in both groups until the 14th day of observation (p &lt;0.05). Among all fecal samples collected from group B (n=4), three different birds shed the pathogen in their feces, out of which two were positive on 3 dpi and one on 7 dpi. The same number of fecal samples was evaluated in group A...

Use of Organic Acids and A Competitive Exclusion Product as Growth Promoter and Salmonella Enteritidis Control in Commercial Turkeys
Provedor de dados: 89
Autores: Milbradt,EL; Okamoto,AS; Padovani,CR; Fascina,VB; Silva,TM; Altarúgio,R; Hataka,A; Schmidt,EMS; Andreatti Filho,RL.
ABSTRACT It is estimated that Salmonella causes one million illnesses in the United States annually, with 19,000 hospitalizations and 380 deaths. There are various serotypes of this bacterium, and the serotypes Typhimurium and Enteritidis are commonly isolated from outbreaks and, in most cases, present resistance to the antibiotics utilized in clinical medicine. One of the current theories to explain the emergence of bacterial resistance is the continuous use of antibiotics as growth promoters in animal feeds. Despite the lack of evidences that antibiotic growth promoters cause bacterial resistance, the poultry industry has explored strategies to reduce or to eliminate the use of antibiotic growth promoters in the production chain, including the...

Salmonella Enteritidis em Aves: Retrospectiva no Brasil
Provedor de dados: 89
Autores: Silva,EN; Duarte,A.
Salmonella Enteritidis (SE) emergiu como um grande problema avícola e de saúde pública no Brasil a partir de 1993. Os estudos epidemiológicos, incluindo a fagotipagem e sonda complementar de rRNA, sugerem a entrada de SE no Brasil via importação de material genético avícola contaminado, provavelmente no final da década de 80. As taxas de crescimento da avicultura brasileira na década de 90 criaram condições favoráveis para a manutenção e proliferação da SE nos plantéis avícolas. Além disso, o uso indiscriminado de antibióticos em aves, particularmente as quinolonas, encorajou a manutenção de lotes positivos para SE. As cepas de SE isoladas de aves têm mostrado alta sensibilidade aos antibióticos de uso comum em avicultura, incluindo as quinolonas....

Autores: Almeida,WAF; Berchieri Junior,A; Barrow,PA.
The competitive exclusion method (EC) was used to protect day-old birds against colonisation of the intestinal tract by Salmonella enterica serovar Enteritidis (SE). The culture prepared in nutrient broth incubated at 37ºC/24 h inhibited SE growth in the caecal contents. The beneficial effect was also observed after serial passage of the feces culture for up to 14 times. The material obtained after 12 serial sub-cultures after storage for 28 days at 4-6ºC also kept its action on SE.

Eighty Salmonella Enteritidis strains isolated from broiler carcasses between May 1995 and April 1996 in the State of Rio Grande do Sul, Brazil, were tested for antibiotic susceptibility using the disk diffusion method. Resistance to colistin, novobiocin, erythromycin and tetracycline was observed in 100% of the isolates. The strains showed intermediate resistance at different levels to kanamycin (1.25%), enrofloxacin (3.75%), neomycin (3.75%), fosfomycin (20%), sulphonamides (86.25%) and nitrofurantoin (90%). Resistance to ciprofloxacin, norfloxacin, gentamicin, polymyxin B, sulphametrim and sulphazotrim was not found. Since resistance to antibiotics especially those introduced in the last decades, was detected, it is recommended that their use must be...

Over the years, Salmonella Heidelberg (SH) has gained prominence in North America poultry production and in the poultry production of other countries. Salmonella Heidelberg has been isolated and reported from poultry and poultry products in Brazil since 1962, whereas Salmonella Enteritidis (SE) has only emerged as a serious problem in poultry and public health since 1993. These strains of Salmonella can cause intestinal problems in newly hatched chicks, and infection may persist until adulthood. Upon slaughter of chickens, Salmonella can contaminate carcasses, a condition that poses a threat to human health. The aim of this study was to compare the fecal excretion of Salmonella Enteritidis and Salmonella Heidelberg in newly hatched chicks (orally...

Autores: Mikcha,Jane M.G.; Ferreira,Antonio J. Piantino; Ferreira,Claudete S. Astolfi; Yano,Tomomasa.
Twenty-five strains of Salmonella enterica serovar Enteritidis isolated from different sources were examined for hemagglutinating activity. Bacteria cultured in different media induced hemagglutination of human erythrocytes, but no reaction was observed with erythrocytes from other animal species. The hemagglutinating expression activity was better for cultures on CFA agar at 37ºC than other conditions examined. The hemagglutination was inhibited by D-mannose, D-mannitol, melibiose, D-raffinose, L-rhamnose and sucrose. The absence of cell-surface appendages in electron microscope examinations suggested a nonfimbrial hemagglutinin. The data suggest that Salmonella Enteritidis produces nonfimbrial mannose-sensitive hemagglutinin, specific for human...

ABSTRACT Food-borne diseases, caused by the pathogenic bacteria, are highly prevalent in the world. Salmonella is one of the most important bacterial genera responsible for this. Salmonella Enteritidis (SE) is one of the non-typhoid Salmonellae that can be transmitted to human from poultry products, water, and contaminated food. In recent years, new and rapid detection methods such as enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) have been developed. In this study, recombinant FliC (rFliC) was produced to be used as an antigen. The immunization was conducted in mice with the purified recombinant FliC (rFliC). The mice were subcutaneously immunized with rFliC and elicited significant rFliC specific serum IgG antibodies. An...

Autores: Kottwitz,Luciana B.M.; Leão,Joice Aparecida; Back,Alberto; Rodrigues,Dalia dos P.; Magnani,Marciane; Oliveira,Tereza C.R.M. de.
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...

In order to study the epidemiology of Salmonella Enteritidis outbreaks and determine the source of contamination so that a recurrence can be avoided, detailed characterization is necessary. Thus, the purpose of this study was to verify whether rep-PCR was able to discriminate among Salmonella Enteritidis isolates. Phage typing, detection of virulence genes and antimicrobial resistance testing were also associated to rep-PCR results. One hundred and two S. Enteritidis isolates from broiler carcasses, food, human, pigs, poultry-related samples, and nine isolates from other countries were genotypically typed by REP-PCR, ERIC-PCR and BOX-PCR, collectively called rep-PCR. Phage typing, detection of virulence genes and antimicrobial resistance testing were also...

Salmonella Enteritidis is one of the agents that is responsible for outbreaks of human foodborne salmonellosis caused by Salmonella Enteritidis and is generally associated with the consumption of poultry products. Inactivated Salmonella Enteritidis cell vaccine is one of the available methods to control Salmonella Enteritidis in breeders and laying hens, however results in terms of efficacy vary. This vaccine has never been tested in Brazil, therefore, the present work was carried out to assess three commercial inactivated Salmonella Enteritidis vaccines allowed in Brazil. Four hundred white light variety commercial laying hens were obtained at one-day-of age. At eight weeks old, the birds were divided into four groups with one hundred animals each. Birds...

The presence of three virulence genes, invA, spvR, and spvC, was determined in Salmonella Enteritidis isolated from poultry, pigs, humans and food. All isolates were positive for the invA gene, with 91.2% being positive for spvR and 90.2% for spvC. There was no significant difference in the prevalence of the virulence genes between isolates from different sources. The results indicate that there is a putative high virulence potential for the S. Enteritidis isolates characterized.

Autores: Oliveira,Kelly; Oliveira,Tereza; Teixeira,Pilar; Azeredo,Joana; Oliveira,Rosário.
Adhesion of microorganisms to food processing surfaces and the problems it causes are a matter of strong concern to the food industry. Contaminated food processing surfaces may act as potential sources of transmission of pathogens in food industry, catering and in the domestic environments. Several studies have shown that adhesion of bacteria to surfaces partly depends upon the nature of the inert surfaces and partly upon the bacterial surface properties. The aim of this study was to compare the adhesion of four different strains of Salmonella Enteritidis to stainless steel 304 (SS 304). The effect of surface hydrophobicity and surface elemental composition on the adhesion process was also analysed. Hydrophobicity was evaluated through contact angle...

ABSTRACT:  We evaluated the influence of temperature on the ability of Salmonella Enteritidis (SE) to form biofilms on stainless steel, polyethylene, and polyurethane surfaces under different hygiene procedures. These materials were placed on SE culture and incubated at 42±1 ºC, 36±1 ºC, 25±1 ºC, 9±1 ºC, and 3±1 ºC for 4, 8, 12, and 24 h. Hot water at 45 ºC and 85 ºC, 0.5% peracetic acid solution, and 1% quaternary ammonia were used for hygienization. Biofilm formation occurred at all temperatures evaluated, highlighting at 3 ºC which has not been reported as an ideal temperature for the adhesion of SE to these materials. The SE adhered more often to polyethylene surfaces than to polyurethane and stainless steel surfaces (P&lt;0.05). Peracetic acid and...

A determinação de produtos eficazes para a desinfecção e que não causem danos ao meio ambiente é um grande desafio para a avicultura orgânica. Neste trabalho foram avaliadas as atividades antibacterianas de quatro desinfetantes: ácido peracético, amônia quaternária, hipoclorito de sódio a 1% e a 0,1% de cloro ativo e do composto de ácidos orgânicos (cítrico, lático e ascórbico), frente às amostras padrão de Escherichia coli, Salmonella enteritidis e Staphylococcus aureus, na presença e ausência de matéria orgânica, sob duas diferentes temperaturas e tempo de contato de 20 minutos. Os ácidos orgânicos mostraram-se menos efetivos na presença de matéria orgânica. No entanto, o ácido peracético, na ausência desta, foi o mais eficaz frente à S. Enteritidis e...
