| isolation of streptococcus suis from swine in nebraska. | streptococcus suis was isolated from swine with localized and diffuse infections. the isolates (n = 121) were unable to grow in broth containing 6.5% nacl. their abilities to hydrolyze esculin were variable, as were their fermentative reactions in lactose, trehalose, raffinose, and inulin. sorbitol was not attacked by any strain. serologic reactions were obtained between the isolates and coagglutination reagents prepared from commercially available antisera to streptococcal groups d, r, or s. | 1984 | 6490489 |
| studies of streptococcus suis type 2 infection in pigs. | investigations into the immunology, pathogenesis and epidemiology of streptococcus suis type 2 infections were carried out in experimental pigs and in naturally-occurring field outbreaks of disease. the capsular polysaccharide from str. suis type 2 was shown to induce opsonic antibodies in pigs when injected with freund's incomplete adjuvant, but difficulties encountered in experimental production of the disease prevented a study of their protective effects. problems with the bactericidal tests ... | 1984 | 6495639 |
| carrier rate of streptococcus suis capsular type 2 in palatine tonsils of slaughtered pigs. | palatine tonsils of 143 slaughtered pigs aged 4 to 6 months were investigated for the presence of streptococcus suis type 2. slices (50 micron) of frozen tonsils were cultured on a selective agar medium containing antibodies against s. suis type 2 in which colonies of this bacterium showed a halo of immunoprecipitation. when tonsils were sectioned in one plane s. suis type 2 was found in 45 of 143 pigs (32%). this percentage increased to 50% when tonsils were sectioned in more then one plane, wh ... | 1984 | 6511877 |
| the bacteriology of endocarditis in slaughter pigs. | streptococcus suis was isolated from 11 (10 per cent) out of 107 cases of endocarditis in slaughter pigs from which bacteria of any kind were isolated. seven of the isolates belonged to the capsular serotypes 1, 2 and 1/2. four were non-typable owing to lack of capsule. the organism isolated most often was erysipelothrix rhusiopathiae, which was found in 68 (64 per cent) cases. | 1984 | 6516848 |
| monitoring herds for streptococcus suis type 2 by sampling tonsils of slaughter pigs. | heads were removed soon after slaughter from the dressed carcases of 155 pigs belonging to 12 herds with a history of streptococcal meningitis and from 180 pigs from four herds believed to be free from this disease. deep scrapings from both tonsils were sown on two selective media. streptococcus suis type 2 was detected in a proportion of pigs from the 12 herds with a history of the disease, including three herds in which no cases were noted during the year this study was made. pigs in six of th ... | 1984 | 6523679 |

| in vitro antimicrobial activity of sulfonamides against some porcine pathogens. | the minimal inhibitory concentrations (mic) of sulfonamides were determined against bordetella bronchiseptica (n = 10), pasteurella multocida (n = 10), haemophilus pleuropneumoniae (n = 20), and streptococcus suis (n = 10) strains isolated from pigs with atrophic rhinitis, pneumonia, or meningitis. sulfonamides tested in an agar dilution method were sulfachloropyridazine, sulfadiazine, sulfadimethoxine, sulfamethazine, sulfadoxine, sulfisoxazole, sulfamerazine, sulfamethoxazole, sulfamethoxypyri ... | 1989 | 2774319 |
| differences in virulence between two strains of streptococcus suis type ii after experimentally induced infection of newborn germ-free pigs. | fifteen newborn germ-free pigs were inoculated with 2 strains, d-282 and t-15, of streptococcus suis type ii. some pigs also were preinoculated with bordetella bronchiseptica, which successfully predisposed them to s suis infection. the 2 streptococcal strains were differentiated by muramidase treatment, which released certain high molecular-weight proteins, termed muramidase-released proteins (mrp), from the cell wall of strain d-282, but not from the cell wall of strain t-15. only strain d-282 ... | 1989 | 2774320 |
| occupational exposure to streptococcus suis type 2. | antibody titres to streptococcus suis type 2 were measured with an enzyme linked immunosorbent assay (elisa) in four occupational groups in new zealand. no veterinary students, 9% of dairy farmers, 10% of meat inspectors and 21% of pig farmers were seropositive to s. suis type 2. the development of antibody to s. suis type 2 was associated with occupational contact with pigs or their meat products. subclinical infection with s. suis type 2 appears to occur in humans and the antibody produced is ... | 1989 | 2776849 |
| monoclonal antibodies for coagglutination of streptococcus suis type 1. | monoclonal antibodies (mabs) were sought that would identify streptococcus suis. spleen cells from balb/c mice immunized with formalin-killed s. suis were fused with the murine cell-line sp-2/0. hybridomas positive for s. suis were identified by a solid-phase radioimmunoassay with a mixture of all available serotypes of s. suis. on further screening with individual serotypes of s. suis (types 1, 2, 1/2, 3, 4, 5, 7, 8, 9 and 12) and other related and unrelated bacteria, a hybridoma specific for t ... | 1989 | 2800308 |
| rapid detection of streptococcus suis serotype 2 in weaned pigs. | a survey to detect streptococcus suis serotype 2 in 1,716 weaned pigs was done in quebec. forty-nine sow herds were included in this survey: in 26 herds, s suis serotype 2 had been isolated during the preceding 12 months and in 23 herds (control), the organism had not been detected during a previous study. swab specimens of the nasal cavity and tonsils of pigs were obtained for bacteriologic culture, and s suis serotype 2 was easily detected by the use of brain-heart infusion agar containing a s ... | 1989 | 2802297 |

| [deafness-blindness caused by streptococcus suis meningitis--epidemiology and rehabilitation]. | a case of blind-deafness due to streptococcus suis meningitis is described. the high incidence of blind-deafness in this disease is emphasized. rehabilitation problems are discussed. special attention is given to the lorm writing as an ideal way of revalidation in this particular patient. | 1990 | 2146855 |
| relationship between intracellular survival in macrophages and pathogenicity of streptococcus suis type 2 isolates. | naturally-occurring streptococcus suis type 2 meningitis affects pigs and man; experimental models of the disease have also been established in pigs and mice. a sustained, high-level bacteraemia is an important phase preceding the development of s. suis type 2 meningitis. the main cellular clearance mechanism for circulating bacteria is the resident hepatic and splenic macrophages. the interaction between various isolates of s. suis type 2 and murine macrophages was investigated to determine whe ... | 1990 | 2199755 |
| streptococcus suis serotypes associated with disease in weaned pigs. | streptococcus suis was recovered from 9 outbreaks of septicaemia and meningitis in weaned pigs between 1979 and 1983. fifteen isolates from 7 outbreaks were identified as s. suis type 9, and 3 isolates from 2 outbreaks as s. suis type 2. three further isolates of s. suis type 2 and an isolate of s. suis type 3 were recovered from cases of bronchopneumonia in weaned pigs from 4 other piggeries. | 1990 | 2222362 |
| infective endocarditis caused by streptococcus suis serotype 2. | infective endocarditis caused by streptococcus suis serotype 2 is not uncommon in pigs but is rare in human beings. we describe the case of a pig-farmer with endocarditis due to s. suis serotype 2 and in whom prolapse of the mitral valve was the predisposing cardiac lesion. streptococcus suis, a possible cause of infective endocarditis in endemic areas, may be confused with other group d streptococci. in suspected cases a history of contact with pigs or raw pork should be sought. | 1990 | 2230181 |
| pathology of streptococcal meningitis following intravenous intracisternal and natural routes of infection. | the distribution of pathological lesions present in 20 cases of naturally-occurring streptococcus suis type 2 meningitis and 20 cases of the disease induced experimentally by intravenous or intracisternal inoculation was examined. it was found that the distribution of lesions was similar; mild lesions were present at the choroid plexuses whilst the most dense cellular accumulations were found at sites of cerebrospinal fluid (csf) efflux, such as arachnoid villi and olfactory nerve sheaths. the d ... | 1990 | 2234313 |
| experimental studies on the comparative infectivity and pathogenicity of streptococcus suis type 2. i. porcine and human isolates in pigs. | piglets between 1 and 40 days of age were inoculated with varying numbers and with different isolates of streptococcus suis type 2 by the intranasal, intravenous and subarachnoid routes. less than 100 organisms of an isolate cultured from apparently normal pigs caused subclinical infection in 1-day-old piglets after intranasal inoculation. this infection was naturally transmitted between litter mates. intravenous inoculation of a similar isolate in 7-week-old pigs resulted in a sub-clinical bact ... | 1990 | 2249710 |
