Catheter associated bloodstream infection caused by R. radiobacter  [cached]
Sood S,Nerurkar V,Malvankar S
Indian Journal of Medical Microbiology , 2010,
Abstract: Rhizobium radiobacter is a gram negative bacillus that is infrequently recognized in clinical specimens but is emerging as an opportunistic human pathogen. Infections due to Rhizobium radiobacter are strongly related to the presence of foreign plastic material and effective treatment often requires removal of the device. We report a case of R. radiobacter bloodstream infection associated with a central venous catheter which was easily controlled by antimicrobial treatment and did not require removal of intravascular device. To the best of our knowledge, this is the first case report from India implicating R. radiobacter as a cause of human infection.

Abstract: Rhizobium radiobacte WSH2601 was mutagenized by using UV-radiation and NTG mutation consecutively. An actinomycin-D resistant mutant, R. radiobacte WSH-F06, was isolated after two runs of screening. The CoQ10 yield of mutant WSH-F06 increased by 16% compared to that of the parent strain. The effects of nutritional and environmental conditions on the production of CoQ10 by R. radiobacte WSH-F06 were investigated in shaking flasks. A complex carbon source consisting of glucose (30 g/L) and molasses (60 g/L) was shown to be suitable. In addition, R. radiobacter WSH-F06 could assimilate a variety of nitrogen sources, including organic and inorganic nitrogen compounds. A compound nitrogen source consisting of (NH4)2SO4 (7 g/L), peptone (5 g/L), yeast extract (5 g/L), corn steep liquor (30 g/L) was developed by using orthogonal experiments. The inoculum size had no obvious effect on CoQ10 fermentation. The optimum initial pH for CoQ10 fermentation was 7.2, while the optimum volume of medium (medium volume vs. flask volume ) was 50 mL/500 mL. Under the optimized fermentation conditions, the CoQ10 yield and the intracellular CoQ10 content reached 34 mg/L and 2.4 mg/g, which were 2.6- and 1.1-fold higher than that of the parent strain under the original conditions, respectively.

生物工程学报 , 2004,
Abstract: 利用放射型根瘤菌WSH2601(Rhizobium radiobacter WSH2601)重点考察了葡萄糖、蔗糖、玉米浆和蛋白胨、添加物以及流加发酵对细胞生长和产辅酶Q10的影响,结果表明, 葡萄糖和蔗糖适合于生产辅酶Q10的最佳浓度分别为30 g/L和40 g/L;辅酶Q10发酵时玉米浆和蛋白胨的最适浓度分别为11g/L和16g/L;添加蕃茄汁、玉米浆能提高发酵液的生物量,玉米浆、异戊醇、L-甲硫氨基酸等能促进辅酶Q10的积累;与分批发酵相比,在7L罐上流加蔗糖其细胞生物量(DCW)和辅酶Q10积累量增加,若在流加蔗糖的同时流加适当浓度的玉米浆能显著提高辅酶Q10的产量,最大产量达到52.4 mg/L;最大生物量(DCW)和胞内辅酶Q10含量(C/B值)分别达到26.4 g/L和2.38 mg/g-DCW,比不流加的分批发酵分别提高53%和33%,比只流加蔗糖分别提高24%和26%。

Saudi Journal of Gastroenterology , 2010,
Abstract: Mycobacterium fortuitum is a rapid growing nontuberculous organism that has rarely been associated with peritonitis in an otherwise healthy host. We describe a patient who developed peritonitis due to the organism after gastric banding operation, which resolved after removal of the gastric band and institution of appropriate antibiotic therapy.

Abstract: We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of “chyle” occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide.

Abstract: La peritonitis bacteriana es una complicación frecuente en los pacientes cirróticos. De los gérmenes etiológicos, Aeromonas es muy poco frecuente. Presentamos un caso clínico de un paciente cirrótico con peritonitis y bacteriemia por Aeromonas hydrophila. Este microorganismo es un bacilo gramnegativo de la familia Vibrionaceae. En el ser humano produce gastroenteritis con mucha frecuencia. De forma excepcional puede dar origen a infecciones extraintestinales, sobre todo en pacientes inmunodeprimidos. La peritonitis por Aeromonas se ha descrito en asociación a peritonitis bacteriana espontánea en pacientes cirróticos, en pacientes en diálisis peritoneal y en casos de peritonitis secundaria a perforación intestinal. Bacterial peritonitis is a frequent complication in cirrhotic patients. Amongst the aetiological germs, Aeromonas is very infrequent. We present the clinical case of a cirrhotic patient with peritonitis and bacteraemia due to Aeromonas hydrophila. This micro-organism is a Gram-negative bacillus of the Vibrionaceae family. It very frequently produces gastroenteritis in the human being. Exceptionally it can give rise to extraintestinal infections, especially in immunodepressed patients. Peritonitis due to Aeromonas has been described in association with spontaneous bacterial peritonitis in cirrhotic patients, in patients on peritoneal dialysis and in cases of peritonitis secondary to intestinal perforation.

Abstract: A 21-year-old man, who had been treated for congenital dilatation of the bile duct 13 years previously, presented with an acute abdomen. The physical examination suggested peritonitis, and an emergent laparotomy was performed. A perforation was foundin the jejunum approximately 100 cm distal to the ligament of Treitz, followed by resection of a 60-cm jejunal segment. No tumorous lesions were found during the operation, and the resected jejunal segment showed only focal myxomatous thickening of the serosa. Despite intensive therapy, he died of uncontrollable septic shock 2 days after the operation. Unexpectedly, however, histological examination revealed a liposarcoma, showing an unclassifiable histology. From the distribution of the lesion and the histological findings, it is thought that a primary lesion was somewhere else, covered by severe adhesions due to the previous operation, and that the tumor cells spreading from it could have caused the jejunal perforation through vascular involvement. Although extremely rare, liposarcomas in the abdomen can cause intestinal perforation. It is important for both clinicians andpathologists to carefully investigate the cause of an unusual clinical presentation such as intestinal perforation.

Abstract: brucellosis is a multisystemic disease that rarely leads to a fatal outcome. while reticuloendothelial system organs are mostly affected, peritonitis and posthepatitic cirrhosis are also complications of brucellosis, though they are very rare. brucella spp. can also trigger immunological reactions. we report a case of brucellosis with peritonitis, renal failure and leucocytoclastic vasculitis caused by brucella melitensis, which led to a fatal outcome. brucellosis should be considered in the differential diagnosis of vasculitic diseases, especially in endemic areas.
