[PMID: 39062701 PMCID: PMC11276239 DOI: 10.3390/genes15070922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/10/2024] [Accepted: 07/12/2024] [Indexed: 07/28/2024] Open
Abstract
Acute febrile illness (AFI) and severe neurological disorders (SNDs) often present diagnostic challenges due to their potential origins from a wide range of infectious agents. Nanopore metagenomics is emerging as a powerful tool for identifying the microorganisms potentially responsible for these undiagnosed clinical cases. In this study, we aim to shed light on the etiological agents underlying AFI and SND cases that conventional diagnostic methods have not been able to fully elucidate. Our approach involved analyzing samples from fourteen hospitalized patients using a comprehensive nanopore metagenomic approach. This process included RNA extraction and enrichment using the SMART-9N protocol, followed by nanopore sequencing. Subsequent steps involved quality control, host DNA/cDNA removal, de novo genome assembly, and taxonomic classification. Our findings in AFI cases revealed a spectrum of disease-associated microbes, including Escherichia coli, Streptococcus sp., Human Immunodeficiency Virus 1 (Subtype B), and Human Pegivirus. Similarly, SND cases revealed the presence of pathogens such as Escherichia coli, Clostridium sp., and Dengue virus type 2 (Genotype-II lineage). This study employed a metagenomic analysis method, demonstrating its efficiency and adaptability in pathogen identification. Our investigation successfully identified pathogens likely associated with AFI and SNDs, underscoring the feasibility of retrieving near-complete genomes from RNA viruses. These findings offer promising prospects for advancing our understanding and control of infectious diseases, by facilitating detailed genomic analysis which is critical for developing targeted interventions and therapeutic strategies.

Abstract
This case describes a neonate who presented with spontaneous Clostridium perfringens meningitis and brain abscess. The abscess was drained, and the infant completed a 6-week course of antibiotics. Throughout this time the infant remained well with no need for intensive care. C. perfringens central nervous system infections are associated with trauma and poor outcomes. This case highlights that the spectrum of disease can include spontaneous infection with a relatively mildly clinical course demonstrating the importance of 16s polymerase chain reaction in culture-negative cases and its role in detecting rare causes of central nervous system infections such as C. perfringens .

Abstract
Clostridium perfringens, a Gram-positive anaerobic bacterium, is well-known for its association with gas gangrene, a severe and rapidly progressing infection characterized by tissue gas production and necrosis. In this case report, we present the instance of a 64-year-old male with poorly controlled diabetes mellitus who developed a C. perfringens-related infection following a traumatic foot wound. The report emphasizes the critical significance of early diagnosis and aggressive treatment in C. perfringens infections, particularly in patients with underlying risk factors. Detailed accounts of clinical findings, laboratory results, computed tomography, and surgical interventions are provided. A multidisciplinary approach proved essential for successful management. The inherent scholarly value of this case is substantiated by its meticulous documentation of the clinical trajectory, diagnostic modalities, and treatment modalities employed. The intricate collaboration across diverse medical disciplines, the uncommon manifestation of the infection following a traumatic foot wound, and the favorable outcome achieved through prompt and multidisciplinary intervention collectively contribute to the exceptional nature and didactic significance of this case. The dissemination of such clinical experiences assumes paramount importance in advancing medical scholarship, cultivating awareness, and engendering a profound comprehension of the complexities associated with C. perfringens infections, thereby enriching the wider scientific and medical community.

Abstract
Innate immune memory explains the plasticity of immune responses after repeated immune stimulation, leading to either enhanced or suppressed immune responses. This process has been extensively reported in peripheral immune cells and also, although modestly, in the brain. Here we explored two relevant aspects of brain immune priming: its persistence over time and its dependence on TLR receptors. For this purpose, we used an experimental paradigm consisting in applying two inflammatory stimuli three months apart. Wild type, toll-like receptor (TLR) 4 and TLR2 mutant strains were used. The priming stimulus was the intracerebroventricular injection of neuraminidase (an enzyme that is present in various pathogens able to provoke brain infections), which triggers an acute inflammatory process in the brain. The second stimulus was the intraperitoneal injection of lipopolysaccharide (a TLR4 ligand) or Pam3CSK4 (a TLR2 ligand). One day after the second inflammatory challenge the immune response in the brain was examined. In wild type mice, microglial and astroglial density, as well as the expression of 4 out of 5 pro-inflammatory genes studied (TNFα, IL1β, Gal-3, and NLRP3), were increased in mice that received the double stimulus compared to those exposed only to the second one, which were initially injected with saline instead of neuraminidase. Such enhanced response suggests immune training in the brain, which lasts at least 3 months. On the other hand, TLR2 mutants under the same experimental design displayed an enhanced immune response quite similar to that of wild type mice. However, in TLR4 mutant mice the response after the second immune challenge was largely dampened, indicating the pivotal role of this receptor in the establishment of immune priming. Our results demonstrate that neuraminidase-induced inflammation primes an enhanced immune response in the brain to a subsequent immune challenge, immune training that endures and that is largely dependent on TLR4 receptor.

Anxiety-like behavior and microglial activation in the amygdala after acute neuroinflammation induced by microbial neuraminidase. Sci Rep 2022; 12:11581.

Abstract
Short-term behavioral alterations are associated with infection and aid the recovery from sickness. However, concerns have raised that sustained behavioral disturbances after acute neuroinflammation could relate to neurological diseases in the long run. We aimed to explore medium- and long-term behavioral disturbances after acute neuroinflammation in rats, using a model based on the intracerebroventricular administration of the enzyme neuraminidase (NA), which is part of some pathogenic bacteria and viruses. Neurological and behavioral assessments were performed 2 and 10 weeks after the injection of NA, and neuroinflammation was evaluated by gene expression and histology. No alterations were observed regarding basic neurological functions or locomotor capacity in NA-injected rats. However, they showed a reduction in unsupported rearing, and increased grooming and freezing behaviors, which indicate anxiety-like behavior. A principal component analysis including a larger set of parameters further supported such anxiety-like behavior. The anxiety profile was observed 2 weeks after NA-injection, but not after 10 weeks. Concomitantly, the amygdala presented increased number of microglial cells showing a morphologic bias towards an activated state. A similar but subtler tendency was observed in hypothalamic microglia located in the paraventricular nucleus. Also, in the hypothalamus the pattern recognition receptor toll-like receptor 4 (TLR4) was slightly overexpressed 2 weeks after NA injection. These results demonstrate that NA-induced neuroinflammation provokes anxiety-like behavior in the medium term, which disappears with time. Concurrent microgliosis in the amygdala could explain such behavior. Further experiments should aim to explore subtle but long-lasting alterations observed 10 weeks after NA injection, both in amygdala and hypothalamus, as well as mild behavioral changes.

Abstract
The maternal death rate remains unacceptably high worldwide, predominantly in areas of poor access to quality health services. According to the WHO, in 2017, 810 women died from preventable causes related to pregnancy and childbirth. Causes of maternal death are plenty, including previous morbidity and unexpected causes. Among the latter are infectious disease-related deaths. Herein, we describe a case of a 29-year-old woman at 37 weeks’ gestation who presented with right upper quadrant pain, which was initially considered to be pregnancy-related. However, she collapsed shortly after the hospital admission. The physical examination revealed severe hypovolemic shock due to a large amount of intraperitoneal free fluid. The patient was immediately rushed into an emergency cesarean section followed by exploratory laparotomy, which demonstrated a large intra-abdominal hemorrhage. The patient and her fetus died in the operating room. An autopsy revealed acute gangrenous cholecystitis along with abundant rod-shaped bacteria within the mucosa and vessels of the gallbladder, gas gangrene and rupture of the spleen, and signs of shock. Clostridium perfringens (CP) was isolated in the culture of a splenic sample. Although CP is a well-known and dreadful infectious etiological agent, catastrophic cases still happen. The acquaintance of this infection by the caregivers is crucial for the early diagnosis and treatment. This is a quite unique way to provide a dismal chance of survival in sepsis cases by this agent.

Abstract
ABSTRACT The radiological depiction of posttraumatic pneumocephalus is due to trapped air in most cases. Although rarely reported, it can also be the result of a gas-forming organism, requiring immediate treatment due to high mortality. Here, we report on an elderly patient with radiological appearance of posttraumatic intracranial pneumocephalus after a wound was closed without recognition of a retained tree branch. The piece of wood served as a vector for transmission of Clostridium perfringens causing the collection of abnormal intracranial air. Radical excision of temporal muscle tissue along with extensive evacuation of the brain abscess and targeted intravenous antibiotics resulted in minor morbidity.Although a piece of wood can easily be missed with current diagnostic imaging, it is crucial that both clinicians and radiologists are aware of the presence of air and its differential diagnosis in posttraumatic pneumocephalus, in order to allow timely treatment in this fatal disease.

Abstract
Clostridium perfringens strains cause a wide variety of human and animal disease, including gas gangrene or myonecrosis. Production of toxins required for myonecrosis, PFO and CPA, is regulated by the C. perfringens Agr-like (CpAL) system via the VirSR two-component system. Myonecrosis begins at the site of infection from where bacteria migrate deep into the host tissue likely using a previously described gliding motility phenotype. We therefore assessed whether gliding motility was under the control of the CpAL/VirSR regulon. The migration rate of myonecrosis-causing C. perfringens strain 13 (S13) was investigated during a 96 h period, including an adaptation phase with bacterial migration (∼1.4 mm/day) followed by a gliding phase allowing bacteria faster migration (∼8.6 mm/day). Gliding required both an intact CpAL system, and signaling through VirSR. Mutants lacking ΔagrB, or ΔvirR, were impaired for onward gliding while a complemented strain S13ΔagrB/pTS1303 had the gliding phenotype restored. Gene expression studies revealed upregulated transcription of pili genes (pilA1, pilA2 and pilT) whose encoded proteins were previously found to be required for gliding motility and CpAL/VirSR-regulated pfoA and cpa toxin genes. Compared to S13, transcription of cpa and pfoA significantly decreased in S13ΔagrB, or S13ΔvirR, strains but not that of pili genes. Further experiments demonstrated that mutants S13ΔpfoA and S13Δcpa migrated at the same rate as S13 wt. We demonstrated that CpAL/VirSR regulates C. perfringens gliding motility and that gliding bacteria have an increased transcription of toxin genes involved in myonecrosis.

Abstract
An 80-year-old Japanese woman with diabetes mellitus was admitted with gastrointestinal symptoms and pyrexia. At presentation, liver abscesses and severe hemolytic anemia were noted. Before detailed diagnostic evaluation and adequate treatment, she suddenly died 2.5 hours after admission. The autopsy and bacteriological examinations revealed liver abscesses and massive intravascular hemolysis caused by Clostridium perfringens as well as other miscellaneous critical pathological findings, including acute renal tubular necrosis, lung edema, and pulmonary fat embolism. In this article, the detailed autopsy results are described and clinicopathologic characteristics on Clostridium perfringens-related sudden death are discussed with a review of the literature.

Abstract
Clostridium perfringens is ubiquitous in the environment and the gastrointestinal tract of warm-blooded animals. While part of the gut microbiome, abnormal growth of C. perfringens causes histotoxic, neurologic, and enteric diseases in a variety of animal species, including humans, due to the production of toxins. There is extremely limited information on C. perfringens infection in non-human primates. Presently, 10 strains were successfully isolated from 126 monkeys and confirmed by molecular and biochemical analyses. All isolates were genotype A based on molecular analysis. Alpha toxin was identified in all isolates. Beta 2 toxin was detected in only three isolates. No other toxins, including enterotoxin, beta, iota, epsilon, and net B toxin, were identified in any isolate. All isolates were highly susceptible to β-lactam antibiotics. Double hemolysis and lecithinase activity were commonly observed in all strains. Biofilm formation, which can increase antibiotic resistance, was identified in 90% of the isolates. The data are the first report the prevalence and characteristics of C. perfringens isolated from captive cynomolgus monkeys.

Abstract
Background Neuraminidase (NA) is a sialidase present, among various locations, in the envelope/membrane of some bacteria/viruses (e.g., influenza virus), and is involved in infectiveness and/or dispersion. The administration of NA within the brain lateral ventricle represents a model of acute sterile inflammation. The relevance of the Toll-like receptors TLR2 and TLR4 (particularly those in microglial cells) in such process was investigated. Methods Mouse strains deficient in either TLR2 (TLR2-/-) or TLR4 (TLR4-/-) were used. NA was injected in the lateral ventricle, and the inflammatory reaction was studied by immunohistochemistry (IBA1 and IL-1β) and qPCR (cytokine response). Also, microglia was isolated from those strains and in vitro stimulated with NA, or with TLR2/TLR4 agonists as positive controls (P3C and LPS respectively). The relevance of the sialidase activity of NA was investigated by stimulating microglia with heat-inactivated NA, or with native NA in the presence of sialidase inhibitors (oseltamivir phosphate and N-acetyl-2,3-dehydro-2-deoxyneuraminic acid). Results In septofimbria and hypothalamus, IBA1-positive and IL-1β-positive cell counts increased after NA injection in wild type (WT) mice. In TLR4-/- mice, such increases were largely abolished, while were only slightly diminished in TLR2-/- mice. Similarly, the NA-induced expression of IL-1β, TNFα, and IL-6 was completely blocked in TLR4-/- mice, and only partially reduced in TLR2-/- mice. In isolated cultured microglia, NA induced a cytokine response (IL-1β, TNFα, and IL-6) in WT microglia, but was unable to do so in TLR4-/- microglia; TLR2 deficiency partially affected the NA-induced microglial response. When WT microglia was exposed in vitro to heat-inactivated NA or to native NA along with sialidase inhibitors, the NA-induced microglia activation was almost completely abrogated. Conclusions NA is able to directly activate microglial cells, and it does so mostly acting through the TLR4 receptor, while TLR2 has a secondary role. Accordingly, the inflammatory reaction induced by NA in vivo is partially dependent on TLR2, while TLR4 plays a crucial role. Also, the sialidase activity of NA is critical for microglial activation. These results highlight the relevance of microbial NA in the neuroinflammation provoked by NA-bearing pathogens and the possibility of targeting its sialidase activity to ameliorate its impact.

Abstract
Legionnaires' disease is a recognised but rare cause of rhabdomyolysis. It can be further complicated with renal impairment. In this case report, we describe a previously healthy, semiactive 50-year-old man who within days was reduced to having periods of dyspnea after minutes of walking in addition to near fatal acute renal failure. He was found to have the rare triad of Legionella pneumonia, renal failure and rhabdomyolysis, which is associated with high morbidity and mortality. He was treated according to guidelines with azithromycin monotherapy and aggressive fluid hydration. 20 days after admission, the patient was walking independently and discharged home.

Abstract
Bovine spongiform encephalopathy (BSE) is an invariably fatal prion disease of cattle. The identification of the zoonotic potential of BSE prompted safety officials to initiate surveillance testing for this disease. In Canada, BSE surveillance is primarily focused on high risk cattle including animals which are dead, down and unable to rise, diseased or distressed. This targeted surveillance results in the submission of brain samples with a wide range of tissue autolysis and associated contaminants. These contaminants have the potential to interfere with important steps of surveillance tests resulting in initially positive test results requiring additional testing to confirm the disease status of the animal. The current tests used for BSE screening in Canada utilize the relative protease resistance of the prion protein gained when it misfolds from PrPC to PrPSc as part of the disease process. Proteinase K completely digests PrPC in normal brains, but leaves most of the PrPSc in BSE positive brains intact which is detected using anti-prion antibodies. These tests are highly reliable but occasionally give rise to initially reactive/false positive results. Test results for these reactive samples were close to the positive/negative cut-off on a sub set of test platforms. This is in contrast to all of the previous Canadian positive samples whose numeric values on these same test platforms were 10 to 100 fold greater than the test positive/negative cut-off. Here we explore the potential reason why a sample is repeatedly positive on a sub-set of rapid surveillance tests, but negative on other test platforms. In order to better understand and identify what might cause these initial reactions, we have conducted a variety of rapid and confirmatory assays as well as bacterial isolation and identification on BSE positive, negative and initially reactive samples. We observed high levels of viable bacterial contamination in initially reactive samples suggesting that the reactivity may be related to bacterial factors. Several bacteria isolated from the initially reactive samples have characteristics of biofilm forming bacteria and this extracellular matrix might play a role in preventing complete digestion of PrPC in these samples.

Complement system activation contributes to the ependymal damage induced by microbial neuraminidase. J Neuroinflammation 2016; 13:115.

Abstract
Background In the rat brain, a single intracerebroventricular injection of neuraminidase from Clostridium perfringens induces ependymal detachment and death. This injury occurs before the infiltration of inflammatory blood cells; some reports implicate the complement system as a cause of these injuries. Here, we set out to test the role of complement. Methods The assembly of the complement membrane attack complex on the ependymal epithelium of rats injected with neuraminidase was analyzed by immunohistochemistry. Complement activation, triggered by neuraminidase, and the participation of different activation pathways were analyzed by Western blot. In vitro studies used primary cultures of ependymal cells and explants of the septal ventricular wall. In these models, ependymal cells were exposed to neuraminidase in the presence or absence of complement, and their viability was assessed by observing beating of cilia or by trypan blue staining. The role of complement in ependymal damage induced by neuraminidase was analyzed in vivo in two rat models of complement blockade: systemic inhibition of C5 by using a function blocking antibody and testing in C6-deficient rats. Results The complement membrane attack complex immunolocalized on the ependymal surface in rats injected intracerebroventricularly with neuraminidase. C3 activation fragments were found in serum and cerebrospinal fluid of rats treated with neuraminidase, suggesting that neuraminidase itself activates complement. In ventricular wall explants and isolated ependymal cells, treatment with neuraminidase alone induced ependymal cell death; however, the addition of complement caused increased cell death and disorganization of the ependymal epithelium. In rats treated with anti-C5 and in C6-deficient rats, intracerebroventricular injection of neuraminidase provoked reduced ependymal alterations compared to non-treated or control rats. Immunohistochemistry confirmed the absence of membrane attack complex on the ependymal surfaces of neuraminidase-exposed rats treated with anti-C5 or deficient in C6. Conclusions These results demonstrate that the complement system contributes to ependymal damage and death caused by neuraminidase. However, neuraminidase alone can induce moderate ependymal damage without the aid of complement.

Abstract
Clostridium perfringens type C strains produce severe disease in humans and animals including enterotoxaemia and hemorrhagic diarrhea. Type C disease is mediated by production of toxins that damage the site of infection inducing loss of bloody fluids. Production of type C toxins, such as CPA, PFO, and, CPB is regulated by the C. perfringens Agr-like (CpAL) quorum sensing (QS) system. The CpAL system is also required to recapitulate, in vivo, intestinal signs of C. perfringens type C-induced disease, including hemorrhagic diarrhea and accumulation of fluids. The intestinal epithelium forms a physical barrier, made up of a series of intercellular junctions including tight junctions (TJs), adherens junctions (AJs) and desmosomes (DMs). This selective barrier regulates important physiological processes, including paracellular movement of ions and solutes, which, if altered, results in loss of fluids into the intestinal lumen. In this work, the effects of C. perfringens infection on the barrier function of intestinal epithelial cells was evaluated by measuring trans-epithelial resistance (TEER). Our studies demonstrate that infection of human enterocytes with C. perfringens type C strain CN3685 induced a significant drop on TEER. Changes in TEER were mediated by the CpAL system as a CN3685ΔagrB mutant did not induce such a drop. Physical contact between bacteria and enterocytes produced more pronounced changes in TEER and this phenomenon appeared also to be mediated by the CpAL system. Finally, immunofluorescence studies demonstrate that C. perfringens type C infection redistribute TJs protein occludin, and Claudin-3, and DMs protein desmoglein-2, but did not affect the AJs protein E-cadherin.

Abstract
Clostridium perfringens strains produce severe diseases, including myonecrosis and enteritis necroticans, in humans and animals. Diseases are mediated by the production of potent toxins that often damage the site of infection, e.g., skin epithelium during myonecrosis. In planktonic cultures, the regulation of important toxins, such as CPA, CPB, and PFO, is controlled by the C. perfringens Agr-like (CpAL) quorum sensing (QS) system. Strains also encode a functional LuxS/AI-2 system. Although C. perfringens strains form biofilm-like structures, the regulation of biofilm formation is poorly understood. Therefore, our studies investigated the role of CpAL and LuxS/AI-2 QS systems and of QS-regulated factors in controlling the formation of biofilms. We first demonstrate that biofilm production by reference strains differs depending on the culture medium. Increased biomass correlated with the presence of extracellular DNA in the supernatant, which was released by lysis of a fraction of the biofilm population and planktonic cells. Whereas ΔagrB mutant strains were not able to produce biofilms, a ΔluxS mutant produced wild-type levels. The transcript levels of CpAL-regulated cpa and pfoA genes, but not cpb, were upregulated in biofilms compared to planktonic cultures. Accordingly, Δcpa and ΔpfoA mutants, in type A (S13) or type C (CN3685) backgrounds, were unable to produce biofilms, whereas CN3685Δcpb made wild-type levels. Biofilm formation was restored in complemented Δcpa/cpa and ΔpfoA/pfoA strains. Confocal microscopy studies further detected CPA partially colocalizing with eDNA on the biofilm structure. Thus, CpAL regulates biofilm formation in C. perfringens by increasing levels of certain toxins required to build biofilms.

Abstract
In the present paper, we describe the facts that took place in the rat brain after a single injection of the enzyme neuraminidase from Clostridium perfringens into the right lateral ventricle. After injection, it diffused through the cerebrospinal fluid of the ipsilateral ventricle and the third ventricle, and about 400 μm into the periventricular brain parenchyma. The expression of ICAM1 in the endothelial cells of the periventricular vessels, IBA1 in microglia, and GFAP in astrocytes notably increased in the regions reached by the injected neuraminidase. The subependymal microglia and the ventricular macrophages begun to express IL1β and some appeared to cross the ependymal layer. After about 4 h of the injection, leukocytes migrated from large venules of the affected choroid plexus, the meninges and the local subependyma, and infiltrated the brain. The invading cells arrived orderly: first neutrophils, then macrophage-monocytes, and last CD8α-positive T-lymphocytes and B-lymphocytes. Leukocytes in the ventricles and the perivascular zones penetrated the brain parenchyma passing through the ependyma and the glia limitans. Thus, it is likely that a great part of the damage produced by microorganism invading the brain may be due to their neuraminidase content.

Abstract
We describe the case of a patient with hemolysis-associated Clostridium perfringens septicemia and review all similar cases published in the literature since 1990, with specific focus on the relationship between treatment strategy and survival. We searched PubMed for all published cases of C. perfringens-associated hemolysis, using the medical subject terms "clostridia," "clostridial sepsis," and/or "hemolysis." All case reports, case series, review articles, and other relevant references published in the English literature since 1990 were included in this study. There were no exclusion criteria. Each case was examined with respect to presenting features of illness, antibiotic regimen, time-to-antibiotic therapy, additional interventions, complications, and patient survival. These variables were entered into a data set and then systematically analyzed with the aid of a statistician, using serial t tests and chi-square analyses. Since 1990, 50 patients of C. perfringens septicemia with hemolysis have been reported. Median age was 61 years (range 31-84), and 58% were male. Mortality was 74%, with a median time to death of 9.7 hours (range 0-96 hours). Of the patients, 35 (70%) were treated medically, while 15 (30%) received antibiotics and surgery. Surgical intervention was associated with significantly improved survival (risk ratio [RR] 0.23, 95% confidence interval [CI] 0.10, 0.53) as was the use of a combination of penicillin and clindamycin (RR of death 0.46, 95% CI 0.25, 0.83). Four patients utilizing hyperbaric oxygen therapy (HBOT) have been reported, and all patients survived. In cases of clostridial sepsis with hemolysis, strong predictors of survival include early initiation of appropriate antibiotics as well as surgical removal of infected foci. The HBOT may also be associated with survival. The disease often progresses rapidly to death, so rapid recognition is critical for the patient survival.

Abstract
Background: Anaerobic bacterial meningitis is rare. It is extremely unusual without a portal of entry as most cases reported have been associated with trauma or neurosurgery. Case Report: We describe this rare case of clostridium meningitis and plesiomonas sepsis in an immunocompetent adult. A 71 year old man with diabetes presented with acute onset severe headaches, obtundation and signs of severe hemolysis following a 2 week game hunting trip in the Swiss Alps. His clinical status progressed rapidly; he died 3 hours after initial presentation. Post mortem lumbar puncture was performed with CSF analysis suggestive of bacterial meningitis. Clostridium perfringens was eventually recovered from the CSF as well as in the blood. Plesiomonas shigelloides was recovered from the blood as well. Conclusions: This is the first case of blood stream infection with these two organisms in a single patient without an obvious portal of entry.

Abstract
Gas gangrene is a painful, rapidly developing and potentially fatal infection despite antibiotic treatment. During the First World War thousands of soldiers died from this disease. Dr Alexis Carrel pioneered a controversial method of irrigating wounds with Dakin's solution to destroy Clostridium perfringens, a bacterium found in heavily fertilised soils that causes gas gangrene. Although this method is no longer used due to the discovery of antibiotics, many of his other ideas, such as scientifically determining the type and number of bacteria and delaying the closure of a wound until the bacteria had been eradicated, are still used today.

Abstract
Massive hemolysis secondary to sepsis caused by Clostridium perfringens is a rare entity but appears fairly often in the literature. In nearly all published reports, the clinical course is rapid and fatal. We describe the case of a 75-year-old woman with diabetes who was admitted with symptoms consistent with acute cholecystitis. Deteriorating hemodynamics and laboratory findings were consistent with intravascular hemolysis, coagulation disorder, and renal failure. Gram-positive bacilli of the Clostridium species were detected in blood along with worsening indicators of hemolysis. In spite of antibiotic and surgical treatment, hemodynamic support and infusion of blood products, the patient continued to decline and died in the postoperative recovery unit 14 hours after admission. Mortality ranges from 70% to 100% in sepsis due to Clostridium perfringens, and risk of death is greater if massive hemolysis is present, as in the case we report. Only a high degree of clinical suspicion leading to early diagnosis and treatment can improve the prognosis. This bacterium should therefore be considered whenever severe sepsis and hemolysis coincide.

Abstract
OBJECTIVE Clostridial sepsis has a very poor prognosis, owing to the life-threatening combination of shock and acute massive hemolysis. No papers have described the clinical features of clostridial sepsis cases in Japan. Therefore, we retrospectively examined the clinical features of patients with systemic inflammatory response syndrome (SIRS) from whose blood cultures Clostridium perfringens was isolated. SUBJECTS AND MATERIALS Blood samples were obtained from SIRS patients and cultured between January 1, 2001 and June 30, 2009. The samples were retrospectively reviewed, and 18 samples were positive for C. perfringens. The medical records of these 18 patients were reviewed for age, gender, underlying disease, past illnesses, results of physical and laboratory testing, and radiographic data. RESULTS All patients were diagnosed with SIRS. Fifteen patients (83.3%) were >65 years old -mean age, 75±2 years (range, 59-88 years). There were more men (13) than women (5). The blood cultures were obtained from patients in various wards: tertiary care center (8), emergency room (5), surgical ward (4), and medical ward (1). Hepatobiliary tract diseases such as gallbladder stones and hepatic carcinoma were the most frequent underlying diseases (8). Five patients died, resulting in an overall mortality rate at 30 days of 27%. In the non-survival group, patients presented with septic shock (4) and gas-forming infection (2), and with significantly lower fibrinogen levels than those in the survival group. Septic shock at initial presentation was significantly associated with 30-day mortality for C. perfringens infection. DISCUSSION AND CONCLUSION There were no specific characteristics among clinical features of C. perfringens infection accompanied with SIRS. This may indicate that, in emergency rooms, diagnosing and initiating appropriate treatment for C. perfringens infection may be considerably difficult. It is important to be especially vigilant in identifying patients with C. perfringens infection underlying SIRS, and accompanied by shock.
