Streptococcus Viridans


Presentation

  • We describe a 62-year-old male with adenocarcinoma of the sigmoid colon with the presentation of infective endocarditis due to infection by Streptococcus viridans, and we also report on the condition's successful treatment.[ncbi.nlm.nih.gov]
  • Abstract An elderly male with a history of diabetes mellitus and a recent dental procedure presented to the emergency department with acute lumbosacral pain and low grade fever.[ncbi.nlm.nih.gov]
  • The data presented suggest that there are subjects who may unknowingly carry penicillin-resistant S. viridans as part of their oral flora.[ncbi.nlm.nih.gov]
  • The diagnosis of subclinical bacterial colonization of the amniotic fluid should be considered in patients presenting with preterm labour and no apparent aetiology.[ncbi.nlm.nih.gov]
  • Three months later, he presented with persistent chest discomfort and fever. Computed tomography (CT) of the thorax revealed evidence of graft infection and the blood culture grew Streptococcus viridans.[ncbi.nlm.nih.gov]
Intermittent Fever
  • Case Report A 4-year-old boy presented with intermittent fever and productive cough for 2 weeks. He was given medications to alleviate the symptoms; however, high fever and shortness of breath were noted 4 days later.[indianpediatrics.net]
Lymphedema
  • This report of CPAN localized to an area of scar lymphedema underscores the importance of lymphatic function in the pathogenesis of CPAN.[ncbi.nlm.nih.gov]
Chest Discomfort
  • Three months later, he presented with persistent chest discomfort and fever. Computed tomography (CT) of the thorax revealed evidence of graft infection and the blood culture grew Streptococcus viridans.[ncbi.nlm.nih.gov]
Unable to Stand
  • On examination of his musculoskeletal system, he was unable to stand and required the support of two people. Examination of the lower limbs revealed painful restriction of hip flexion and extension, with a power of 5/5 in both hips and knees.[jmedicalcasereports.biomedcentral.com]

Abdominal Mass
  • ", keywords "abdominal mass, abscess, adolescent sexual behavior, streptococcal infection", author "Lashondria Simpson-Camp and Richardson, {Elizabeth Jane} and Alaish, {Samuel M.[jhu.pure.elsevier.com]
Oral Ulcers
  • On examination, Behcet-mimicking symptoms were observed, such as genital and oral ulcers and arthritis. Furthermore, S. viridans was found in the urethral discharge culture.[ncbi.nlm.nih.gov]
Ciliary Injection
  • The 28-year-old man visited the authors' hospital due to ciliary injection and hypopyon over left eye. On examination, Behcet-mimicking symptoms were observed, such as genital and oral ulcers and arthritis.[ncbi.nlm.nih.gov]
Spontaneous Rupture of Membranes
  • Of the 18 cases, maternal infection was documented in 6 cases; delivery was preceded by spontaneous rupture of membranes in 9 cases and vaginal bleeding in 7 cases.[ncbi.nlm.nih.gov]
Ataxia
Urethral Discharge
  • Furthermore, S. viridans was found in the urethral discharge culture. Under the impression of ReA, which was triggered by S. viridans, NSAID and antibiotics were prescribed.[ncbi.nlm.nih.gov]
Vaginal Bleeding
  • Of the 18 cases, maternal infection was documented in 6 cases; delivery was preceded by spontaneous rupture of membranes in 9 cases and vaginal bleeding in 7 cases.[ncbi.nlm.nih.gov]
Dysuria
  • Two weeks later fever, dysuria, diarrhea, sterile inflammatory arthritis of lower limbs, enthesitis, dactylitis, conjunctivitis, and uveitis consecutively developed.[ncbi.nlm.nih.gov]

Workup

  • In the face of penicillin resistance, additional considerations for workup, including microbiological assays for antimicrobial synergism become necessary in the selection of a therapeutic regimen.[ncbi.nlm.nih.gov]
  • Often, the workup for infectious cause returns fruitless and the patient’s clinical course may be the sole clue in making the diagnosis. Here, we present a rare case of hookah-induced Streptococcus viridans pneumonia.[aspergillus.org.uk]
  • Because of the frequent association of abscess formation, a routine workup in Anginosus group bacteremia should include a search for abscess. In Vitro Susceptibility VGS are presumed to be uniformly susceptible to penicillin.[antimicrobe.org]
HLA-B27
  • A 26-year-old male patient with mitral valve prolapse and HLA-B27 antigen received endodontic treatment for dental caries.[ncbi.nlm.nih.gov]

Treatment

  • Complete resolution of ocular and systemic symptoms was achieved after 2 months of treatment. Streptococcus viridans is potential microorganisms of ReA. Careful survey and prompt treatment is necessary.[ncbi.nlm.nih.gov]
  • In addition, a different strain of S. viridans was cultured 1 month after treatment had begun. It is therefore important to repeat cultures and antimicrobial sensitivity testing during treatment of infective endocarditis.[ncbi.nlm.nih.gov]
  • Clinicians should note local patterns of virulence and antibiotic resistance in S. viridans and adjust treatment strategies accordingly.[ncbi.nlm.nih.gov]
  • We describe a 62-year-old male with adenocarcinoma of the sigmoid colon with the presentation of infective endocarditis due to infection by Streptococcus viridans, and we also report on the condition's successful treatment.[ncbi.nlm.nih.gov]
  • After treatment with appropriate antibiotics, the patient converted to sinus rhythm with sotalol hydrochloride, and the eustachian valve vegetation resolved. This is the first reported case of eustachian valve endocarditis caused by S viridans.[ncbi.nlm.nih.gov]

Prognosis

  • Although advances in antibiotic therapy and surgical techniques have improved the prognosis of endocarditis, 1 the mortality rate in recent decades has held steady at 15% to 50%. 2-11 Improving this prognosis will require identifying patients at higher[revespcardiol.org]
  • Therefore, early diagnosis and initiation of adequate antibiotic therapy is important for improving the long-term prognosis of patients suffering from this rare disease.[ekjm.org]
  • INTRODUCTION Traumatic endophthalmitis usually carries a grave visual prognosis. The commonly used orthodontic extraoral traction devices may, on rare occasions, cause severe penetrating ocular injury with resulting endophthalmitis.[healio.com]

Etiology

  • Streptococcus viridans is also an important etiologic agent causing septicaemia in neutropenic patients with haematological diseases.[ncbi.nlm.nih.gov]
  • The organisms are most abundant in the mouth, and one member of the group, S. mutans, is the etiologic agent of dental caries. This group of bacteria is often implicated in subacute endocarditis associated with dental procedures.[osmosis.org]
  • In the literature, there are just few data about the association between PCT levels and endocarditis and sepsis but there are not etiological differentiations particularly for those sustained by Streptococcus viridans.[ncbi.nlm.nih.gov]
  • With only the organism, Streptococcus viridians, isolated in her cultures, an etiology of direct ascension from the lower genitourinary tract is implicated.[jhu.pure.elsevier.com]
  • The etiology of osteitis that is characterized by a fibroblast and giant-cell proliferation with bone destruction and new bone formation has been discussed. 2.[journals.lww.com]

Pathophysiology

  • Pathophysiology The portal of entry for S bovis bacteremia is the gastrointestinal tract. The urinary tract, hepatobiliary tree and the oropharynx can also be sources of infection in some cases.[emedicine.medscape.com]

Prevention

  • It is therefore recommended that the preferable antibiotic used for the prevention of BE should be determined by an antibiogram.[ncbi.nlm.nih.gov]
  • Therefore the diagnosis and prevention of these infections is critical in health care. Purpose: The aim of this in-vivo study was to determine the prevalence of viridans streptococci in abscesses occurring in the maxillofacial region.[jdt.tums.ac.ir]
  • Pretreatment with warfarin prevented vegetation formation, but animals still developed endocarditis at the same rate after injection of 10 6 S. viridans .[iai.asm.org]
  • Prevention The best way to limit the consequences of PJI is to prevent the infection before it occurs.[aoj.amegroups.com]
