In our case, though liver abscess was suspected, drainage was not performed immediately.5. 2. In literature, hemolysis was reported to be induced by infections with organisms such as clostridium, malaria, bartonella, babesiosis, Bacillus cereus, mycoplasma pneumoniae and streptococcus pneumonia.1 Massive haemolysis is not a rare complication of C. perfringens bacteraemia, occurring in 7 to 15% of cases.2. Lippincott Journals Subscribers, use your username or email along with your password to log in. The characteristic double zone of clear beta-hemolysis around a colony is clearly seen (arrow). Unfortunately, many patients deteriorate rapidly and die before aggressive management with appropriate antibiotics and blood product transfusion was initiated, as seen in our case. The deduced amino acid sequence of beta-toxin has significant homology with that of Staphylococcus aureus alpha-toxin, gamma-toxin and leukocidin. Sepsis is common, but sepsis-associated massive intravascular hemolysis, which is usually rapidly fatal, is rarely encountered in clinical practice. What is more frightening is that in the large majority of cases the time from admission to death was within hours, as it was in our case. 1996 Sep;64(9):3930-3. doi: … Large scale purification of Clostridium perfringens toxins: a review. C. perfringens is nonmotile and generally has a distinctive “boxcar” appearance on Gram stain of clinical material or subcultures. Arrangement Of Cells – Clostridium perfringens is arranged singly, in short chains or in small bundles. Streptococcus pyogenes, or Group A beta-hemolytic Strep (GAS), displays beta hemolysis. Yellow (+) in CCFA. Other Clostridia produce several different-looking colony types, so the culture appears mixed. Registered users can save articles, searches, and manage email alerts.

Van Bunderen CC, Bomers MK, Wesdorp E, Peerbooms P, Veenstra J. beta-hemolysis exhibited by isolated colonies HUS is a clinical syndrome charaterzed by microangiopathic haemolytic anemia with variable degrees of thrombocytopenia and renal failure. Allthese are the virulence factors, which contribute to pathogen-esis of the diseases (Table 29-2). Clostridium perfringens is a major cause of human and animal enteric disease. Colonies of wild-type CN3718 and the complemented strain were surrounded by a double zone of hemolysis, including the inner zone of beta-hemolysis indicative of C. perfringens PFO activity (21, 23, 24). Whenever massive hemolysis occurs, mortality of 70 to 100%, due to acute renal failure and septicemia, can be expected. Highlight selected keywords in the article text. Clostridium perfringens type C strains are defined by carrying the 2 typing toxin genes cpa (encoding for α-toxin or CPA) and cpb (encoding for β-toxin or CPB).

Overview By [Victor Progar] Clostridium perfringens (C. perfringens) is a common bacteria that is responsible for food poisoning, gastrointestinal disease, gas gangrene and related necrotic conditions in humans and other mammals [13].Some other members of the genus Clostridium, which are closely related to C. perfringens, include: C. botulinum, which produces the botulinum toxin … These enteric toxins are found to be involved in the … Please try again soon. Clostridium perfringens usually produces a double zone of beta-hemolysis. Spherocytes, ghost cells, and sometimes C. perfringens can be seen in a stained blood smear.

In our case, normal platelet count and no evidence of microangiopatic haemolytic anaemia helped us exclude the diagnosis of HUS. The bacterium produces several toxins when present inside the gastrointestinal tract. A few Clostridium spp. Six hours after admission, the patient developed acute respiratory distress, low back pain and cranberry-colored urine. β (beta) hemolysis – a clear zone of complete hemolysis produced by beta-hemolytic streptococci such as S. equi subsp. HUS usually occurs in healthy young children (> 6 months to <5 years of age) and is preceded by gastroenteritis. Efforts were also made to investigate the origin of bacteremia, and liver absecss was suspected (right hypochondriac pain, tenderness of right upper abdomen and liver mass on abdominal ultrasound). The high mortality of such patients can be explained by several reasons. C. perfringenscan cause massive intravascular hemolysis and non-traumatic gas gangrene in immunocompromised hosts with diabetes, underlying malignancy or a history of surgery for biliary and pancreatic cancer (1). Clostridia possess no one typical colony morphology. Keyword Highlighting Clostridium perfringens — histotoxic or enterotoxigenic infections. Streptococcus agalactiae displays this property. Clostridium perfringensalpha toxinis a toxinproduced by the bacteriumClostridium perfringens(C. perfringens) and is responsible for gas gangreneand myonecrosisin infectedtissues. Timely antibitics were given after blood culture was taken. 3. Though it is common in the gastrointestinal tract and genitourinary tracts of healthy subjects, C. perfringens is rarely realized to be a pathogen which can cause blood stream infections. Some weakly beta-hemolytic species cause intense beta hemolysis when grown together with a strain of Staphylococcus. Maria Taciana Holanda Cavalcanti I, II; Tatiana Porto I, II; Ana Lúcia Figueiredo Porto III; Igor Viana Brandi IV; José Luiz de Lima Filho I; Adalberto Pessoa Junior II, *.

The colonies were in- Other significant findings included marked leukocytosis to 40×109/L, acute renal failure (Cr 133.2 μmol/L), metabolic acidosis and marked transaminase elevations (AST 1547 U/L, alanine aminotransferase (ALT) 286 U/L). This hemolysis is due to lysis of RBCs in the BA by the cytotoxin Streptolysin S. Data is temporarily unavailable. This case presented with typical symptoms and signs of sepsis, including fever, chills, and leucocytosis. Abdominal pain and massive intravascular. Certain strains also produce enterotoxin and neuraminidase.These toxins are responsible for the pathogenesis gas gangrene (myonecrosis), food poisoning, enteritis, and enterotoxemia. Clostridium perfringens(C. perfringens) is an anaerobic, gram-positive bacillus which occurs naturally in the human gastrointestinal and urogenital tract.

Physical examination revealed a temperature of 39, heart rate of 110 beats/min, blood pressure of 101/69 mmHg, and a respiratory rate of 25 breaths/min. The patient died approximately 13 hours after admission. Despite treatment with corticosteroids, the patient became increasingly dyspneic and agitated, complained of venous puncture points bleeding and developed cardiorespiratory arrest approximately 9 hours after admission. your express consent. In one study, diabetes was present in 30% of patients with C. perfringens bacteremia, being the only risk factor in 15%, as in our case.2, Sudden severe hemolytic anemia was believed to be caused by toxin production of C. perfringens. Laboratory studies were significant for hemoglobin of 56 g/L, which had dropped from 135 g/L 7 hours before, TBil 180.44 μmol/L (IBil 157.36 μmol/L), hematocrit 11.4%, lactate dehydrogenase (LDH) 5714 U/L, and creatine kinase (CK) 673 U/L, all consistent with severe hemolysis.
