| identification of streptococcus porcinus from human sources. | streptococcus porcinus is normally associated with infections in swine. cultures of this streptococcal species are rarely reported from human infections. in the past 10 years, we have identified 13 cultures of s. porcinus from human sources from persons living in the united states and canada. seven of the strains were identified in the past 15 months. nine of the strains were of a single serogroup, provisionally called c1. in addition, nine of the strains were isolated from the genitourinary tra ... | 1995 | 7714197 |
| clinical pharmacokinetic characterization of norfloxacin nicotinate in swine following systemic administration. | norfloxacin nicotinate (nfn) is a new water-soluble fluoroquinolone antibacterial agent. the in vitro activity of nfn for microorganisms isolated from swine and the pharmacokinetic properties of nfn following single intravenous (i.v.), intramuscular (i.m.) and subcutaneous (s.c.) administration were investigated. the minimal inhibitory concentrations (mic's) of nfn for a wide range of reference (atcc-american type culture collection) microbial swine isolates, comprising 21 bacterial and 5 mycopl ... | 1994 | 7941848 |
| bacterial isolation from slaughtered pigs associated with endocarditis, especially the isolation of streptococcus suis. | bacterial isolation from slaughtered pigs with endocarditis was carried out from 1985 to 1994. a total of 495 (0.025%) out of 2,006,127 pigs were diagnosed as having endocarditis. though bacteria were significantly isolated from 399 of the 495 pigs, bacteria could not be isolated in 96 pigs (19.4%). in 11 pigs, 2 bacterial species were isolated from heart lesion. streptococcus suis was isolated from 127 cases (25.7%), streptococcus dysgalactiae from 75 (15.2%), erysipelothrix rhusiopathiae from ... | 1997 | 9035085 |
| cross-reactions of reagents from streptococcal grouping kits with streptococcus porcinus. | streptococcus porcinus is usually associated with swine. because we have received several isolates from human sources that had cross-reacted with commercial group b streptococcal reagents, we examined several commercial kits to determine the extent of this cross-reaction. fifteen reference and 15 clinical strains of s. porcinus were tested for cross-reactions with group b streptococcal reagents from 12 different commercial kits. cross-reactions were detected with all group b reagents, but the nu ... | 1997 | 9196216 |
| studies on biochemical, serological and further characteristics of streptococcus porcinus. | in the present study 70 streptococcus porcinus isolates could be identified and further characterized by cultural and biochemical properties, by determination of their antibiotic susceptibility and by serological classifications. the s. porcinus included serogroup- and serotype-reference strains, presumptive group candidates and isolates obtained from routine diagnostics. all cultures investigated appeared with a broad zone of beta-haemolysis on sheep blood agar showed a camp-like reactivity in ... | 1998 | 9640104 |
| species identification of streptococcus porcinus by restriction fragment length polymorphism analysis of 16s ribosomal dna. | streptococcus porcinus reference strains and routine isolates belonging to lancefield's serogroup e, p, u and v and to various serotypes of serogroup e were examined for their 16s ribosomal dna fingerprint pattern. oligonucleotide primers complementary to 16s rrna genes were used to amplify gene fragments by polymerase chain reaction from genomic dna. the amplified 1450 bp fragment was subsequently digested with the restriction enzyme bpii resulting in two fragments with a size of approximately ... | 1998 | 9769079 |
| new pcr primers for the sensitive detection and specific identification of group b beta-hemolytic streptococci in cerebrospinal fluid. | group b beta-hemolytic streptococci (gbs) are a major cause of sepsis and meningitis in newborn babies. although penicillin remains an effective treatment, there has been no decline in mortality. the rapid identification of gbs in cerebrospinal fluid (csf) would improve the diagnosis of meningitis, but data from several previous studies indicate that the sensitivity of polymerase chain reaction (pcr) is not better than culture. following extraction and precipitation of dna, we have used semi-nes ... | 1999 | 10508556 |
| streptococcus porcinus as a cause of spontaneous preterm human stillbirth. | we report, to our knowledge, on the first case of a woman suffering stillbirth due to streptococcus porcinus on the basis of microbiologic and histologic data. | 2004 | 15365054 |
| [evaluation of prolex for the rapid identification of streptococci isolated in medical microbiology]. | the need to rapidly identify streptococci responsible for acute infectious diseases has led to the development of agglutination techniques that are able to identify streptococcal group antigens (a, b, c, d, f, and g) directly from primoculture colonies on blood agar. the prolex agglutination tests (pro-lab diagnostics, richmond hill, ontario, canada), distributed in france by i2a, have been used for the determination of group antigens of 166 isolates of streptococci and enterococci previously id ... | 2004 | 15465260 |
| phenotypic and genotypic characteristics of streptococcus porcinus isolated from human sources. | the phenotypic and genotypic characteristics of 25 streptococcus porcinus isolates recovered from human sources were investigated and compared to the characteristics of 17 reference strains obtained from nonhuman sources. all of the s. porcinus isolates were beta-hemolytic (wide zones), susceptible to vancomycin, gave positive results for the leucine aminopeptidase and l-pyrrolidonylarylamidase tests, and produced acids from mannitol and sorbitol. most of them were positive for the camp test and ... | 2005 | 16145112 |
| streptococcus pseudoporcinus sp. nov., a novel species isolated from the genitourinary tract of women. | streptococcus strains from animal and human sources identified biochemically as streptococcus porcinus were investigated by 16s rrna gene sequencing. the nine human strains isolated between 1997 and 2005 formed a single cluster with more than 2.1% dissimilarity with s. porcinus strains from animal sources. a novel species, streptococcus pseudoporcinus sp. nov., is proposed. | 2006 | 16825387 |
| epidemiological, biochemical and antimicrobial susceptibility characteristics of streptococcus pseudoporcinus isolated in quebec, canada, from 1997 to 2006. | from 1997 to 2006, in the province of quebec, canada, 15 isolates of streptococcus pseudoporcinus from 1 urine and 14 vaginorectal cultures were recovered from the genitourinary tract of pregnant women. all these women originated from the caribbean or sub-saharan africa (p=0.00045 compared with a suitable control group). the s. pseudoporcinus isolates were compared to eight isolates of streptococcus porcinus identified in quebec from 1995 to 2006, all from animals, of which five were swine. 16s ... | 2007 | 18033830 |
| microbiological identification and analysis of swine tonsils collected from carcasses at slaughter. | the primary objective of this 7-month study was to determine the prevalence of porcine pathogens of the tonsil of the soft palate of swine at slaughter. additional objectives were to determine if sampling the carcasses of normal or abnormal hogs provided different microbiological profiles and if the slaughter plant provides a feasible sampling frame and environment for detecting and monitoring important pathogens in tonsils that have health implications for both swine and humans. a total of 395 ... | 2011 | 21731180 |

| vaginorectal streptococcus porcinus in pregnancy: an emerging pathogen? | streptococcus porcinus has previously been isolated from the genitourinary tract of reproductive-aged women. however, very little is known about the pathogenicity of this microorganism in pregnancy. the study aimed to report pregnancies complicated by vaginorectal s. porcinus and associated adverse outcomes. | 2013 | 23595037 |
| evaluation of methods for identification and determination of the taxonomic status of strains belonging to the streptococcus porcinus-streptococcus pseudoporcinus complex isolated from animal, human, and dairy sources. | ninety-seven animal, human, and dairy streptococcus porcinus or streptococcus pseudoporcinus isolates in the cdc streptococcus strain collection were evaluated on the basis of dna-dna reassociation, 16s rrna and rpob gene sequencing, conventional biochemical and rapid id 32 strep identification methods, and antimicrobial susceptibility testing to determine their taxonomic status, characteristics for species differentiation, antimicrobial susceptibility, and relevance of clinical source. nineteen ... | 2012 | 22933599 |
