1. Optimization of flask culture medium and conditions for hyaluronic acid production by a streptococcus equisimilis mutant nc2168
A mutant designated NC2168, which was selected from wild-type Streptococcus equisimilis CVCC55116by ultraviolet ray combined with60Co-γ ray treatment and does not produce streptolysin, was employed to produce hyaluronic acid (HA). In order to increase the output of HA in a flask, the culture medium and conditions for NC2168 were optimized in this study. The

2. Produção da proteína recombinante estreptoquinase (Streptococcus dysgalactiae subsp. equisimilis) em biorreator utilizando diferentes estratégias de batelada alimentada
A estreptoquinase (SK) é uma proteína extracelular produzida por uma variedade de linhagens de Streptococcus beta-hemolíticos, é uma proteína ativadora do plasmigênio composta de 414 aminoácidos com uma massa molecular de aproximadamente 47 kDa. A SK forma um complexo equimolar com o plasminogênio. Esse complexo resultante pode converter diretamente

3. Surto causado por Streptococcus dysgalactiae subsp equisimilis, em um hospital, no Sul do Brasil
O estreptococo beta-hemolítico do grupo C de Lancefield tem sido considerado patógeno humano emergente, mostrando importante papel como agente oportunista, implicado algumas vezes em infecções hospitalares e surtos. Este estudo está relatando o primeiro surto de infecção hospitalar causado pelos Streptococcus dysgalactiae subsp. equisimilis no Brasil.

4. COMPARISON BETWEEN BIOCHEMICAL TEST AND THE PARTIAL ANALYSIS OF SEQUENCES OF THE HSP60 GENE FOR THE IDENTIFICATION OF Streptococcus equi ISOLATES / COMPARAÇÃO ENTRE TESTES BIOQUÍMICOS E ANÁLISE DA SEQUÊNCIA PARCIAL DO GENE hsp60 PARA A IDENTIFICAÇÃO DE ISOLADOS DE Streptococcus equi
Streptococcus equi subesp. equi é o agente etiológico da adenite eqüina. Outros agentes pertencentes ao mesmo grupo, como S. equi subesp. zooepidemicus são freqüentemente isolados de animais com sinais de adenite, podendo originar diagnósticos equivocados. As diferenças bioquímicas são pequenas para as subespécies de S. equi, enquanto o potencial v

5. Functional analysis of a relA/spoT gene homolog from Streptococcus equisimilis.
We examined the functional attributes of a gene encountered by sequencing the streptokinase gene region of Streptococcus equisimilis H46A. This gene, originally called rel, here termed relS. equisimilis, is homologous to two related Escherichia coli genes, spoT and relA, that function in the metabolism of guanosine 5',3'-polyphosphates [(p)ppGpp]. Studies wi

6. Role of beta-hemolytic group C streptococci in pharyngitis: incidence and biochemical characteristics of Streptococcus equisimilis and Streptococcus anginosus in patients and healthy controls.
The biochemical characteristics and the isolation rates of the two Lancefield group C streptococcal species (S. equisimilis and S. anginosus) from patients with pharyngitis and asymptomatic controls were compared. Some 239 strains of beta-hemolytic group C streptococci were isolated from 1,480 patients (209 strains) with pharyngitis and 227 controls (30 stra

7. Streptococcus equisimilis Pneumonia in a compromised host.
A fatal case of Streptococcus equisimilis pneumonia and septicemia is described in a young man with Hodgkin's disease. The disease course consisted of exudative pharyngitis, macular rash, septic shock, disseminated intravascular coagulation, deep vein thrombosis, and pulmonary embolization. S. equisimilis was isolated from blood, throat, and sputum cultures

8. Human Fc(gamma) receptors for differentiation in throat cultures of group C "Streptococcus equisimilis" and group C "Streptococcus milleri".
The biochemical characteristics and the presence of human Fc(gamma) receptors of 52 throat isolates of group C beta-hemolytic streptococci were examined. Among these isolates, 38 were identified as "Streptococcus milleri" and 14 were identified as "Streptococcus equisimilis." The differentiation of group C "S. equisimilis" from "S. milleri" with identical gr

9. Role of group C beta-hemolytic streptococci in pharyngitis: epidemiologic study of clinical features associated with isolation of group C streptococci.
All Lancefield group C beta-hemolytic streptococci isolated over 12 months from college students with clinical pharyngitis and age-matched healthy controls were identified. Clinical features of upper respiratory tract infection and pyogenic pharyngitis as well as colony counts were tabulated for each patient according to throat culture results. Of 1,480 pati

10. Analysis of a Viridans Group Strain Reveals a Case of Bacteremia Due to Lancefield Group G Alpha-Hemolytic Streptococcus dysgalactiae subsp. equisimilis in a Patient with Pyomyositis and Reactive Arthritis
Streptococcus dysgalactiae is classified by a combination of phenotypic and genotypic characteristics into Lancefield group C alpha-hemolytic Streptococcus dysgalactiae subsp. dysgalactiae and Lancefield group C, group G, and group L beta-hemolytic Streptococcus dysgalactiae subsp. equisimilis. In this study, we report the isolation of a catalase-negative, a

11. Cloning, Expression, Sequence Analysis, and Characterization of Streptokinases Secreted by Porcine and Equine Isolates of Streptococcus equisimilis
Streptokinases secreted by nonhuman isolates of group C streptococci (Streptococcus equi, S. equisimilis, and S. zooepidemicus) have been shown to bind to different mammalian plasminogens but exhibit preferential plasminogen activity. The streptokinase genes from S. equisimilis strains which activated either equine or porcine plasminogen were cloned, sequenc

12. Six-Month Multicenter Study on Invasive Infections Due to Streptococcus pyogenes and Streptococcus dysgalactiae subsp. equisimilis in Argentina
During a 6-month period, 95 invasive infections due to Streptococcus pyogenes and group C or group G Streptococcus dysgalactiae subsp. equisimilis were recorded from 40 centers of 16 cities in Argentina. We describe here epidemiologic data available for 55 and 19 patients, respectively, associated with invasive infections due to S. pyogenes and S. dysgalacti
