Abstract
A 68-year-old man underwent total gastrectomy and splenectomy for adenocarcinoma and low anterior resection for carcinoma in tubulo-villous adenoma of the rectum. Broad-spectrum antibiotics were administered for postoperative pancreatic fistula. Methicillin-resistant Staphylococcus aureus enteritis occurred on the 50th postoperative day and cecal perforation followed. The patient underwent construction of cecostomy with peritoneal drainage, and vancomycin was administered orally and per cecostomy for 2 weeks. The patient recovered well and was discharged at 35 days after re-operation in good general condition.

Abstract
Background Nosocomial Methicillin-resistant Staphylococcus aureus (MRSA) enteritis is rare but can be fatal unless it is detected at an early stage and treated effectively. Dysbiosis of the gut is one of the leading reasons of MRSA enteritis. Fecal microbiota transplantation (FMT) is a burgeoning treatment to rectify this imbalance. But the impact of FMT on MRSA enterocoitis is still unknown yet. Methods A total of 5 patients diagnosed as MRSA enteritis during the early postoperative period were given vancomycin 2 g/day for 3 days and FMT for three continuous days as a standard treatment. Result There was a 100 % clinical response rate that all the symptoms resulting from MRSA enterocolitis disappeared and MRSA in the feces eliminated clearly. The microbiota profile in feces of the patients also regained balance. Conclusion FMT can be a preferential measure to restore the dysbiosis caused by MSRA enterocolitis.

Abstract
An outbreak of diarrhea on a large commercial mink farm affected 5,000 of 36,000 neonatal mink kits, with 2,000 dying within a 2-week period. Affected kits were severely dehydrated, and their furcoats and paws were covered with yellow- to green-tinged mucoid feces. On necropsy, the small intestines of examined animals were markedly distended by serous to mucoid fluid. Microscopically, there was prominent colonization of the intestinal villar epithelium by gram-positive bacterial cocci in the absence of inflammation and morphologic changes in villous enterocytes. The colonizing bacteria were phenotypically identified as belonging to the Staphylococcus intermedius group of bacteria. This was confirmed by nucleic acid sequence analysis of the 16S ribosomal RNA gene. Further nucleic acid sequencing of polymerase chain reaction (PCR) amplicons from the superoxide dismutase gene and the heat shock protein 60 gene differentiated the isolate as Staphylococcus delphini. Production of staphylococcal enterotoxins A and E was demonstrated with a commercial ELISA-based immunoassay. Sequencing of PCR amplicons confirmed the presence of the enterotoxin E gene, but PCR amplification of the enterotoxin A, B, C, or D genes was not successful. Although direct causation was not confirmed in this study, the authors postulate that the observed hypersecretory diarrhea in these mink kits was the result of colonization of the small intestine by S delphini and subsequent production of enterotoxin.

Abstract
We studied the characteristics of methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) strains that caused enteritis. In a previous report, we demonstrated that both phenotypic and genotypic changes were associated with MRSA enteritis; and we hypothesized that the accessory gene regulator (agr), which is a global regulator of staphylococcal virulence and upregulates several exoproteins, is the key factor associated with the development of MRSA enteritis. In this study, we examined 12 MRSA isolates associated with enteritis from stool samples and 17 MRSA isolates not associated with enteritis that had the following characteristics: the strains associated with enteritis had the same genotype (genotype A), as detected by pulsed-field gel electrophoresis, or the strains were isolated from stools. The differences between strains that caused enteritis and those that did not cause enteritis strains were examined by quantitative reverse transcription-PCR to assess RNAII, agrA, RNAIII, and tst expression and by sequencing of the agr locus. The levels of expression of agrA, RNAIII, and tst were higher by the MRSA isolates associated with enteritis than by the MRSA isolates not associated with enteritis, whether or not they were of the same genotype. The levels of expression of RNAII by almost all the clinical isolates were similar. Sequencing of the agr locus showed that all MRSA isolates that caused enteritis have agr mutations, whereas the MRSA isolates that did not cause enteritis, with three exceptions, did not. Many of the isolates associated with enteritis had the same mutation, especially at the C-terminal end of agrA. These results suggest a trend in which mutations in the agr locus modify the expression of agrA and RNAIII and the production of toxin, all of which may increase the virulence and influence the occurrence of MRSA enteritis.

Abstract
INTRODUCTION Nosocomial MRSA infection has become an important healthcare issue. We present 6 cases of MRSA enteritis, acquired following bowel surgery and ileostomy formation. PATIENTS AND METHODS The data set was obtained from the experience of one consultant surgeon over 6 years in one medical centre. The clinical features and course of six patients that developed MRSA enteritis postoperatively were obtained through review of case notes and laboratory data. RESULTS Four male and two female patients (age range, 22-80 years) developed a clinical syndrome postoperatively requiring treatment within the high dependency unit. Three developed respiratory distress syndrome, and one died from multi-organ failure. Exploratory laparotomy carried out in three patients was negative. All patients were MRSA-negative on admission but had swabs positive for MRSA from ileostomy site postoperatively. All of the three patients who had ileostomy effluent cultured for MRSA had positive results. DISCUSSION Fever, abdominal pain, distension and high stoma output in the early postoperative period following bowel surgery should alert the clinician to the possibility of MRSA enteritis. Patients require aggressive resuscitation and culture of ileostomy effluent for MRSA. Exploratory laparotomy has no obvious benefits. As MRSA enteritis has the potential to be a lethally effective disseminator of MRSA, such clinical features should prompt early instigation of appropriate infection control practices.

Abstract
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) with Panton-Valentine leukocidin (PVL) genes is increasing worldwide. Nosocomial outbreak-derived (hospital-acquired) MRSA (HA-MRSA) in Japan in the 1980s was also largely PVL(+). PVL(+) HA-MRSA and CA-MRSA shared the same multi-locus sequence type (ST30) and methicillin resistance cassette (SCCmecIV), but were divergent in oxacillin resistance, spa typing, PFGE analysis or clfA gene analysis. PVL(+) HA-MRSA, which probably originated in PVL(+)S. aureus ST30, was highly adhesive (carrying cna and bbp genes), highly-toxic (carrying luk(PV) and sea genes) and highly drug-resistant. PVL(+) HA-MRSA was once replaced by other PVL(-) HA-MRSA (e.g., ST5), and is re-emerging as CA-MRSA.

Abstract
Following a hysterectomy a 43-year-old woman developed colicky abdominal pain and profuse postoperative diarrhoea. Examination was unremarkable and initial investigations revealed a normal plain abdominal X-ray initially, but later there was some small bowel dilatation and evidence of raised inflammatory markers. No cause was identified at exploratory laparotomy 2 days post operation. Flexible sigmoidoscopy was normal. The patient was empirically treated with oral vancomycin for presumed Clostridium difficile diarrhoea, although subsequent stool cultures were negative for the usual intestinal pathogens and C. difficile toxin. The diarrhoea persisted for 9 days. By day 10 stool cultures had grown methicillin-resistant Staphylococcus aureus, establishing the diagnosis. To our knowledge this is the first report of methicillin-resistant S. aureus enteritis following hysterectomy.

Abstract
In the early 1990s, severe enteritis caused by methicillin-resistant Staphylococcus aureus (MRSA enteritis) was prevalent in Japan, but the incidence has since decreased. We compared the genotypes and phenotypes of 12 isolates that caused MRSA enteritis (enteritis isolates), detected between 1990 and 1993, with 186 non-enteritis isolates detected between 1998 and 2002. Organisms were investigated using pulsed-field gel electrophoresis (PFGE), coagulase typing and reverse passive latex agglutination to detect production of staphylococcal enterotoxins (SE) and toxic shock syndrome toxin-1 (TSST-1); and polymerase chain reaction (PCR) for detection of the structural genes entA, entB, entC, entD and tst, which encode proteins SE-A, SE-B, SE-C, SE-D and TSST-1, respectively. The 12 enteritis isolates were classified into four types and four subtypes. Only seven of the 186 non-enteritis isolates had PFGE patterns indistinguishable from the enteritis isolates. Eight of the 12 enteritis isolates had entA, entC and tst, and produced high levels of SE-A and TSST-1, but not SE-C. Of the 186 non-enteritis isolates, 157 produced SE-C and TSST-1, but not SE-A. The seven non-enteritis isolates with a PFGE pattern indistinguishable from the enteritis isolates did not produce SE-A, and showed relatively low levels of TSST-1 production. These isolates may have continued to inhabit our ward since the earlier outbreak, but acquired a different phenotype. In conclusion, the disappearance of MRSA enteritis may have resulted from the decreased incidence of enteritis-causing clones and phenotypical changes.

Abstract
BACKGROUND Postoperative infection of intestine with methicillin-resistant Staphylococcus aureus (MRSA) is fatal in some cases. The object of this study was to establish a mouse model for the infection, providing a useful tool for investigating mechanisms in the progression of infection. METHODS Mice were pretreated with cyclophosphamide, injected orally or directly into jejunum with MRSA prepared from a postoperative patient, and then given 5 daily doses of antibiotics. Forty-eight hours after the injection, bacterial translocation and serum endotoxin levels were examined. Macrophage depletion was carried out by the administration of liposome-encapsulated dichloromethylene diphosphate (Cl(2)MDP), 4 days before MRSA injection. RESULTS Injection into the jejunum but not oral administration of MRSA induced enteritis with diarrhea and resulted in death in most cyclophosphamide-treated mice. Translocation of MRSA in mesenteric lymph nodes and liver was observed, concomitantly with E. coli infection. Endotoxin-resistant C3H/HeJ mice infected with MRSA survived longer than endotoxin-sensitive C3H/He mice, but also died within a week after MRSA injection. Selective depletion of macrophages induced infection in mice that were not pretreated with cyclophosphamide. CONCLUSION We established a mouse model for the fatal MRSA infection which induced enteritis with diarrhea, that will be a useful tool for investigating the mechanisms for sometimes fatal MRSA infection of the intestine in postoperative patients. The presence of E. coli or endotoxin seemed to play a major role in the mortality of mice in the early days of MRSA-induced enteritis, but other factors, probably from MRSA, in the later days. Phagocytes were quite important for protection against the MRSA infection.

Abstract
Serum interleukin 15 (IL-15) levels were measured in 77 patients who were consecutively admitted to our intensive care unit. Postoperative enterocolitis occurred in four patients and Methicillin-resistant Staphylococcus aureus (MRSA), but not Clostridium difficile, was identified in the faecal specimens from these patients. The IL-15 levels in the patients with MRSA enterocolitis were significantly elevated compared with those of other MRSA infections without enterocolitis including pneumonia (n=6) and cholangitis (n=1), and other MRSA non-colonized patients (n=66) (21.2+/-5.2 pg/ml vs 4.3+/-0.2, 4.3+/-0.5). Notably, an increase in serum IL-15 was observed just before clinical manifestation of severe diarrhoea. Our findings suggest that IL-15 may be associated in the pathogenesis of postoperative enterocolitis and its serum level may be a severity indicator of the disease.

Abstract
The incidence of postoperative infections caused by methicillin-resistant Staphylococcus aureus (MRSA) in Japan has been increasing dramatically. In March 1990, we assigned special doctors in infection control (infection control doctor, ICD), and defined comprehensive controls against MRSA infection. A total of 3536 cases of digestive tract surgery performed at our department were studied during the period between September 1987 and August 1997. We changed the use of antibiotics to prevent postoperative infection. Cefazolin (CEZ) was employed for surgery of the upper digestive tract, including esophagus, stomach, duodenum, and gallbladder. Cefotiam (CTM) was employed for surgery of the lower digestive tract, liver, and pancreas. In esophageal resection, the tracheal tube was extracted during the early postoperative period, and for cervical esophagogastroanastomosis, the autosuture was changed to layer-to-layer anastomosis. We have achieved successful control of postoperative MRSA infection, the incidence having decreased to 0.3% (9/2703). In conclusion, our methods of control against postoperative MRSA infection implies that comprehensive measures of prevention, including the reviewed specification and usage of antibiotics and operation management, have been well implemented. This value is the lowest and the first of any domestic hospital or institute in Japan, suggesting a continued and significant decrease.

Abstract
Our hospital, a 756-bed non-teaching general hospital, acts as a tertiary ambulatory center and has an 89-bed surgical ward. The present study is concerned with how the presence of an infection control practitioner (ICP) affects the results of infection control. Methicillin-resistant Staphylococcus aureus (MRSA) nosocomial infections (according to the definitions of nosocomial infections) of the Centers for Disease Control and Prevention in the surgical ward were retrospectively studied in two periods: from February 1989 to June 1990 and from January 1992 to December 1994. Infection control procedures were established in November 1989 when the surgical ward was transferred to a new building. An ICP was present from November 1989 to June 1990, and from July 1993 to December 1994 and supervised infection control so that the infection control procedures were uniformly practiced by all staff in the surgical ward. After the appointment of the ICP, the infection rate per 100 admissions decreased from 3.2 to 1.2 (P < 0.05) in the first period and from 2.5 to 1.7 in the second period. After the appointment of the ICP, the infection rate per 1000 patient days decreased from 1.11 to 0.49 in the first period and from 1.00 to 0.67 in the second period. Hospital stay periods for patients with the same enterotoxin and coagulase types overlapped in 16 patients in the absence of the ICP and in 4 patients in the presence of the ICP, respectively, in the first period. The present study suggested that infection rates decreased in the presence of an ICP.

Abstract
PURPOSE The aim of this study was to define a distinctive clinical entity of multiple intestinal ulcerations and perforations in infants. METHODS Two infants underwent abdominal exploration for surgical abdomen and were noted to have multiple intestinal ulcerations and perforations. A peculiar and unique surgical finding, numerous transverse linear ulcerations scattered along the entire small intestine, prompted us to search for similar instances. Five similar cases were additionally identified by members of the Korean Association of Pediatric Surgeons. The clinical courses, the surgical findings, and the results of bacterial cultures were reviewed. As well, the tissues of resected intestines were examined histopathologically. RESULTS The characteristics of this entity are as follows. (1) It usually occurs in infants who have been treated with broad-spectrum antibiotics. (2) Despite broad-spectrum antibiotic treatment, diarrhea and abdominal distension developed progressively and deteriorated. (3) Histological evaluation showed mucosal ulcers with neutrophil infiltration, submucosal microabscesses, and colonies of Gram-positive cocci. (4) Methicillin-resistant Staphylococcus aureus (MRSA) was the predominant organism cultured from the body fluid. (5) Only two cases, the completely resected one and the one immediately treated postoperatively with vancomycin, survived. CONCLUSIONS This entity is caused by multiple intestinal ulcerations and perforations secondary to MRSA enteritis in infants. It has a high mortality rate because of its difficult diagnosis. However, early recognition of this entity can lead to successful treatment.

Abstract
The postoperative development of methicillin-cephem-resistant Staphylococcus aureus (MRSA) enteritis can be fatal unless it is detected at an early stage and treated with effective antibacterial agents. We report herein a Japanese multicenter collaborative clinical study on the efficacy and safety of oral vancomycin hydrochloride (VCM) in the treatment of MRSA enteritis. A total of 49 patients who had been diagnosed as having, or were strongly suspected of having, MRSA enteritis during the early postoperative period, were given oral VCM as four standard doses of 0.5 g per day. The VCM concentrations in the blood, urine, and feces were then measured. No side effects were observed and the clinical efficacy of oral VCM in the 31 evaluable patients was excellent. There was a 100% clinical response rate and a 95.8% bacterial elimination rate in the feces. The clinical complete response (CR) rate to oral VCM differed significantly between patients in whom MRSA was detected only in the feces (100%) and those in whom MRSA was isolated from an additional source (57%) (P < 0.01). Although VCM concentrations in the stools were extremely high, the levels in the blood and urine were very low. These results demonstrate that oral VCM should be the treatment of choice for postoperative MRSA enteritis due to its safety and efficacy.
