Intra-abdominal abscesses secondary to Streptococcus anginosus infection in a postpartum patient: A case report and review of the literature  [PDF]
Rehab Shabana, Lindsay Berbiglia, John Barnwell, Ronald Cheek, Mark Wolf, Bernard Gonik
Open Journal of Obstetrics and Gynecology (OJOG) , 2012, DOI: 10.4236/ojog.2012.23048
Abstract: Although rare, infection with Streptococcus anginosus has a known predilection for abscess formation. We report here a case of a 20 year-old, otherwise healthy female patient noted to have developed abdominal and pelvic abscesses secondary to Streptococcus anginosus infection. Although the inciting focus of the pathogen remains unclear in our patient, this case report emphasizes the importance of rapid identification of the organism and highlights the approach to therapeutic options in the management of such cases.

Pyogenic liver abscess secondary to disseminated Streptococcus Anginosus from Sigmoid Diverticulitis
Murarka Shishir,Pranav Fnu,Dandavate Varsha
Journal of Global Infectious Diseases , 2011,
Abstract: Pyogenic liver abscess secondary to dissemination from Sigmoid diverticulitis is rare. Streptococcus anginosus has been linked to abscesses but has been rarely reported from a Sigmoid diverticulitis source. We report a case of liver abscess in which the source was confounding but eventually was traced to Sigmoid diverticulitis on laparotomy.

Revista chilena de pediatría , 2005,
Abstract: Objetivo: Comunicar el caso de un adenoflegmón cervical por Streptococcus intermedius y caracterizar aspectos clínicos y microbiológicos de la infección por esta bacteria. Caso: Ni a de 3 a os, con historia de fiebre y aumento de volumen cervical anterior y supraclavicular izquierdo de 5 días de evolución, diagnosticándose adenoflegmón cervical; la punción revela Streptococcus intermedius. Se trató con cloxacilina y luego penicilina EV y completó tratamiento de 10 días con cotrimoxazol. Discusión: Streptococcus intermedius corresponde a una de las tres especies del grupo "anginosus" o "milleri", integrante a su vez del grupo viridans. Forma parte de la flora bacteriana habitual orofaringea, de tubo digestivo y vagina. Tiene capacidad de migrar a otros parénquimas, produciendo infecciones abscedantes, a veces polimicrobianas y de difícil erradicación. Estudios nacionales de susceptibilidad antimicrobiana reportan sensibilidades cercanas al 100% a Penicilina y Cefotaxima. Diversos protocolos microbiológicos de identificación rápida permiten su diferenciación bacteriológica, ayudando a establecer alternativas terapéuticas más adecuadas Cervical lymphadenitis due to Streptococcus intermedius in a 3 years-old girl.

Abstract: streptococcus anginosus group and its species constellatus, anginosus and intermedius, produce suppurative infections. its microbiological identification is complex because it can be b-hemolytic and shares lancefield antigens with other streptococci. this group grows as small colonies and presents a characteristic smell, but if only latex test for carbohydrate c agglutination is used it can be erroneously classified. the aims of this publication were to evaluate an algorithm that includes three biochemical tests, and to describe in vitro susceptibility to antibiotics and clinical characteristics of infections caused by streptococcus anginosus group. streptoccoccal strains belonging to groups c, g and f were evaluated, determining its colony characteristics in order to select small colony strains that were included into the proposed low cost algorithm (beta-glucurosidase and voges proskauer tests) comparing them with api rapid id 32 strept? method, considered the gold standard. two hundred nineteen strains were studied, 101 had a morphological profile compatible with the anginosus group, identifying s. constellatus in 58% (59/101), s. anginosus in 37% (37/101) and s. intermedius in 5% (5/101). strains were isolated mainly from pyogenic infections (61%, 62/101), specially from abdominal origin. high grade of penicillin and cefotaxime susceptibility (98%) and low grade resistance to erithromycin and clindamycin (6,8 and 5% respectively) were observed. mean patient age was 30 years old (2-85), a similar sex distribution with predominance of inpatients. these results document the usefulness of the proposed low cost algorithm for detection of s. anginosus group. in our experience this bacterial group maintains good susceptibility to penicillin and cefotaxime, and we recommend a continous surveillance of clindamycin and erythromycin susceptibility

Abstract: Background: The roles of group C and F streptococci in causing endemic pharyngitis are still controversial, although group C streptococci are implicated in the outbreaks of pharyngitis and associated disorders. Aim: The aim of this study was to determine the prevalence and the role of these groups of β-hemolytic streptococci in acute pharyngitis with emphasis on the Streptococcus anginosus group. The antimicrobial susceptibility profile of these bacterial isolates and their ability to produce some virulence factors was also determined. Materials and Methods: Throat swab specimens were collected from 177 patients suffering from acute pharyngitis who had been admitted to the Hilla Teaching Hospital, Hilla, Iraq, during October 2009 to January 2010. The necessary biochemical tests were conducted and the organisms identified using standard procedures. Susceptibility of isolates pathogens to several antibiotics was examined using standard susceptibility testing. Virulence factors of these isolates were also determined using standard methods. Results: Results revealed that a total of 67 isolates belonged to β-hemolytic streptococci, of which 11(16.4%) isolates belonged to anginosus group streptococci, which possessed Lancefield group C and F antigens. Most of these bacterial isolates have the ability to produce more than one virulence factor such as capsule, hemolysin, CFA III, and lipase enzyme. The bacterial isolates were highly resistant to ampicillin, cefotaxime, and cefepime while they exhibited moderate resistance to tetracycline, ceftriaxone, and ciprofloxacin. On the other hand, they showed a high sensitivity to vancomycin, ofloxacin, and clindamycin. Conclusion: This study concluded that groups C and F Streptococci were implicated as a cause of acute pharyngitis in 6.2% of the specimens among other groups of streptococci. Most of these isolates have the ability to produce more than one virulence factor. There was a high rate of resistance among isolates for β-lactam antibiotics; however, they were highly susceptible to vancomycin, ofloxacin, and clindamycin.

Revista médica de Chile , 2013,
Abstract: The etiology of brain abscesses is mostly polymicrobial. Streptococci and anaerobic bacteria are the most commonly isolated pathogens. We report a previously healthy female without predisposingfactors, presenting with a bifrontal cerebritis caused by a Streptococcus anginosus group infection. The patient developed a brain abscess and a subdural collection with severe intracranial hypertension offatal evolution. The etiologic diagnosis was made culturing the material obtained from the subdural collection. It is presumed that, within the Streptococcus anginosus group, Streptococus intermedius could have been the causing bacteria, given its central nervous system tissue tropism and its predisposition to form brain abscesses.

Journal of Microbiology and Infectious Diseases , 2012,
Abstract: Viridans group Streptococcus, a bacterium of the oral flora has a low-virulence and rarely causes liver abscess. A 40-yearoldmale patient was admitted to the hospital complaining of high fever and malaise. A physical examination revealedpoor oral hygiene; there were caries on many teeth, and he had hepatomegaly. A hepatic abscess was identified inhis abdominal tomography. Streptococcus anginosus was isolated from the drainage material, and the bile ducts werenormal in his MRI cholangiography. An immunocompetent case of liver abscess caused by Streptococcus anginosusoriginated most probably from oral flora is presented here. J Microbiol Infect Dis 2012; 2(1):33-35
