1. Vacinas recombinantes contra erisipela suína: desenvolvimento integrado de bioprocesso, da biologia molecular ao biorreator
A erisipela suína é uma das enfermidades que causam grandes prejuízos na suinocultura em todo o mundo. A doença é causada pela bactéria Erysipelothrix rhusiopathiae, e a proteína de superfície SpaA desse microrganismo é um de seus principais antígenos. Neste trabalho, estudou-se o desenvolvimento de vacinas recombinantes contra a erisipela suína a

2. Otimização das condições de cultivo de Erysipelothrix rhusiopathiae para produção de vacina contra erisipela suína
Swine erysipelas is one of the diseases responsible for the great economic losses in swine-producing areas of the world. The bacteria Erysipelothrix rhusiopathiae is the causative agent of erysipelas, and the vaccines currently available for prevention of this disease are produced with the whole broth culture containing the inactivated microorganism or its l

3. Isolamento de Erysipelothrix sp. de tonsilas de suínos em frigoríficos / Isolation of Erysipelothrix sp. from tonsils of slaugther pigs
Swine erysipelas, caused by Erysipelothrix rhusiopathiae, is responsible for enormous economic losses related to abortions and mainly to the chronic form of the disease, due to the costs of treatment, reduced growth rate and carcasss quality. Although Erysipelothrix sp. is not a demanding organism, there are difficulties associated to its laboratorial identi

4. Antibiotic resistance of Erysipelothrix rhusiopathiae isolated from pigs with chronic swine erysipelas.
The susceptibility of 258 isolates of Erysipelothrix rhusiopathiae from slaughtered pigs affected with chronic erysipelas in Japan to antimicrobial agents was determined. A total of 111 (43.0%) strains showed resistance to erythromycin, oleandomycin, oxytetracycline, or dihydrostreptomycin. Plasmids were not detected. This is the first report of resistance o

5. Use of an Enrichment Broth Cultivation-PCR Combination Assay for Rapid Diagnosis of Swine Erysipelas
We have previously described the creation by Tn916 mutagenesis of avirulent transposition mutants from a highly virulent strain of Erysipelothrix rhusiopathiae, the causative agent of swine erysipelas. In this study, we cloned a 2.2-kb DNA fragment which flanked the Tn916 insertion in an avirulent mutant (strain 33H6) and evaluated the possibility that this

6. Serotyping of 800 Strains of Erysipelothrix Isolated from Pigs Affected with Erysipelas and Discrimination of Attenuated Live Vaccine Strain by Genotyping
Eight hundred Erysipelothrix strains isolated between 1992 and 2002 from swine with erysipelas in Japan were serotyped. Thirty-seven, 47, 73, and 643 strains were isolated from animals with acute septicemia, urticaria, chronic endocarditis, and chronic arthritis, respectively, of which 381, 146, 254, and 19 isolates belonged to serotypes 1a, 1b, and 2b and o

7. Enzyme-Linked Immunosorbent Assay Employing a Recombinant Antigen for Detection of Protective Antibody against Swine Erysipelas
The specificities and sensitivities of five recombinant proteins of the surface protective antigen (SpaA) of Erysipelothrix rhusiopathiae were examined by indirect enzyme-linked immunosorbent assay (ELISA) with the aim of developing a reliable serological test for the detection of protective antibody against E. rhusiopathiae. Fully mature protein and the N-t

8. Serotype, antimicrobial susceptibility, and pathogenicity of Erysipelothrix rhusiopathiae isolates from tonsils of apparently healthy slaughter pigs.
Erysipelothrix rhusiopathiae was isolated from tonsils of 63 (10.5%) of 600 apparently healthy slaughter pigs in the Kanto area of Japan in February and July 1984. The isolation rate was significantly higher during July than in February. Of these 63 isolates, 34 isolates (54.0%) were serotype 7, 20 isolates (31.7%) were serotype 2, 6 isolates (9.5%) were ser

9. Truncated Surface Protective Antigen (SpaA) of Erysipelothrix rhusiopathiae Serotype 1a Elicits Protection against Challenge with Serotypes 1a and 2b in Pigs
Erysipelothrix rhusiopathiae is a causal agent of swine erysipelas, which is of economic importance in the swine industry by virtue of causing acute septicemia, chronic arthritis, and endocarditis. However, little is known about the genetic properties of its protective antigens. Recently, a surface protective antigen (SpaA) gene was identified from serotype

10. Erysipelothrix rhusiopathiae: an occupational pathogen.
Erysipelothrix rhusiopathiae is a nonsporulating, gram-positive, rod-shaped bacterium which was identified more than 100 years ago as the etiologic agent of swine erysipelas. Since then, it has been found to cause infection in several dozen species of mammals and other animals. Humans become infected through exposure to infected or contaminated animals or an

11. Immunological Characterization of a Protective Antigen of Erysipelothrix rhusiopathiae: Identification of the Region Responsible for Protective Immunity
The gene encoding a protective protein antigen of the gram-positive bacterium Erysipelothrix rhusiopathiae, an important veterinary pathogen responsible for erysipelas in swine and a variety of diseases in animals, was cloned and sequenced. The gene encodes a polypeptide of 597 amino acids plus a putative signal sequence of 29 amino acids, resulting in a mat

12. Direct and rapid detection of Erysipelothrix rhusiopathiae DNA in animals by PCR.
Erysipelothrix rhusiopathiae is a gram-positive rod capable of causing erysipelas in swine. To establish a method for specifically detecting E. rhusiopathiae for practical applications, such as for the inspection of slaughterhouses, the feasibility of using primers derived from the DNA sequence coding for 16S rRNA in a PCR-specific detection system was inves
