“…In our outbreak it was impossible to determine the incubation period because there was no person or no food incriminated definitely. However, it was similar with the other outbreaks caused by GGS as of explosive occurence, course, clinical symptoms and response to treatment of penicillin (7)(8)(9).…”

an explosive epidemic of pharyngitis occured among the staff working atIntensive Care Units and Operation Rooms of Türkiye Yüksek İhtisas Teaching Hospital, The symptoms were indistinguishable from those of group A streptococcal pharyngitis. Sore throat and weakness were the prominent symptoms in (91% and 87%, of patients respectively). In a two-day period, throat cultures were taken from 377 personnel and 121 (32%) of them were found to be positive for group-G beta-hemolytic streptococci. The configuration of the epidemic curve suggested a common source of exposure. Respiratory spread of streptococci in such a rapid fashion would be unlikely. Sixteen of the 121 positive throat cultures were obtained from the staff of the catering firm which provided the food services for the hospital staff. Most of these catering firm personnel were serving the departments where the epidemic occured. With these data, the outbreak was considered to be foodborne. PFGE analysis of randomly selected 40 (including the 16 strains isolated from the catering firm personnel) strains showed only one digestion pattern. Prompt treatment with penicillin was given to all the sick personnel and a 9-day religious holiday approaching consequently terminated the outbreak. Control cultures were negative for all the subjects.Key Words: Group G Shreptococci, outbreak, PFGE Ankara Türkiye Yüksek İhtisas Eğitim ve Araștırma Hastanesi Yoğun Bakım Kliniklerinde ve Ameliyathanelerinde çalıșan personel arasında Ocak 2004'de bir farenjit salgını gelișmiștir. Hastaların semptomları A grubu streptokok farenjiti bulgularıyla örtüșmekte olup, hastaların %91'inde boğaz ağrısı, %87'sinde ise genel halsizlik izlenmiștir. İki gün içerisinde 377 personelden boğaz kültürü alınmıș, bu hastaların 121'inin (%32) kültüründe G-grubu beta hemolitik streptokok üremiștir. Salgın eğrisi incelendiğinde, streptokokların solunum yolu ile bu șekilde hızla yayıl-ması mümkün olmadığı, bu hastaların aynı enfeksiyon kaynağına maruz kaldıkları düșünülmüș-tür. 121 pozitif kültür örneğinin 16'sının, salgının ortaya çıktığı kliniklere hastane personeli yemeklerini dağıtan yemek firması elemanlarına ait olduğunun anlașılması üzerine, salgının gıda kaynaklı olduğu düșünülmüștür. Yemek firması personelinden izole edilen 16 örnek dahil olmak üzere, rastgele seçilen 40 örneğin PFGE analizi sonuçları, tek bir kesim paternini ortaya koymuștur. Tüm hastalanan personele penisilin tedavisi bașlanmıș, salgını takiben bașlayan dokuz günlük bayram tatili esnasında salgın sona ermiș, kontrol kültürlerinde üreme gözlen-memiștir.Anahtar Sözcükler: G grubu streptokok, salgın, PFGE

Beta-hemolytic group G streptococci (GGS) are increasingly recognized as a source of substantial morbidity, causing mild to severe sporadic infections as well as outbreaks. The purpose of this study was to determine the genetic diversity and antibiotic resistance of GGS in Israel in order to aid in prevention and control. A total of 325 GGS isolates were collected in Israel between 2007 and 2011 from three determined settings: (1) carriage (n = 60), an observational longitudinal carriage study in the IF, (2) non-invasive (n = 166), clinical sporadic and epidemic non-invasive cases in the IDF, and (3) invasive (n = 99) cases of bacteremia collected during this period in Israel from a similar age group, at the national Streptococcal Reference Center. All isolates were characterized genetically and by their antibiotic-resistance profile. emm typing revealed 35 distinct types and subtypes among 228 S. dysgalactiae subsp. equisimilis (SDSE) isolates, with high genetic diversity. An additional 97 GGS were identified as Streptococcus anginosus (SAG). The proportion of SDSE was higher in the invasive (100 %) and non-invasive (63.8 %) isolates compared to the carriage ones (38.3 %). Clindamycin, erythromycin, azithromycin and tetracycline resistance was detected in 6.6 %, 8.6 %, 9.7 % and 37.6 % of isolates, respectively. Overall, the most resistant isolates were in the invasive group and the fewest were in the SAG group. Considerable genetic diversity and common antibiotic resistance were revealed among GGS strains which differed according to the epidemiologic settings. Further clinical, epidemiological and basic research of GGS as a pathogen is warranted.

“…equisimilis is responsible for epidemic tonsillopharyngitis in adults and children (7,17,20,36) and for sporadic episodes of tonsillopharyngitis in adults (1,5,11,15,18) and can be found as a cause of bacteremia, endocarditis, pneumonia, and meningitis. Cases of exudative group G streptococci tonsillopharyngitis are known to be associated with contaminated food (8).…”

β-Lactam Failure in Treatment of Two Group G Streptococcus dysgalactiae subsp. equisimilis Pharyngitis Patients

We present two cases of exudative pharyngitis due to Streptococcus dysgalactiae subsp. equisimilis , Lancefield group G. While the participation of this organism as an agent of pharyngitis is well documented, we focus on failure of beta-lactam therapy, a phenomenon that is well described for pharyngitis due to Streptococcus pyogenes . Therefore, these case reports add to our knowledge of pharyngitis caused by non- S. pyogenes streptococci.
