This report describes a case of septicemia and meningitis secondary to dog bites by two different dogs on two consecutive days. The case is noteworthy because of the unusual characteristics of the etiologic agent and the inability to place the etiologic agent into any currently defined genus or to identify it by the existing systems of classification. The organism is a small, thin, Gram-negative bacillus after 24 hours of incubation on blood agar; after prolonged incubation, it becomes filamentous. The organism is catalase- and oxidase-positive, hydrolyzes esculin, and forms acid in glucose, xylose, and maltose after 21 days' incubation. The organism does not manifest lysis on sheep blood agar, and does not grow on MacConkey, Salmonella-Shigella, Centrimide, nutrient, or Kligler iron agars. The tests for urea, nitrate reduction, and indol are negative. The unidentified Gram-negative bacillus showed susceptibility to all antimicrobials tested except gentamicin.

Biochemical and serological properties of 60 strains of Streptococcus bovis isolated from healthy pigeons and from pigeons that died from S. bovis septicemia were determined. On the basis of the hemolysis of bovine erythrocytes, the production of polysaccharides on saccharose-containing media, and the fermentation of mannitol, inulin, trehalose, and L-arabinose, the isolates were classified in five biotypes and two subbiotypes. Slide agglutination and microagglutination tests using monospecific rabbit antisera allowed the classification of all isolates in five serotypes.

Although gut permeability increases and bacterial translocation occurs under certain pathological conditions, it remains unknown whether gut absorptive capacity (GAC) is altered early after the onset of sepsis. The aim of the present study was to investigate this and also to determine whether diltiazem has any effect on GAC in early sepsis. Rats were lightly anesthetized and cecal ligation and puncture (CLP) was performed. A nasogastric tube was inserted, cannulation of various blood vessels was carried out, and the animals were allowed to recover from anesthesia. One hour after CLP, one group of animals received a 1-ml bolus of normal saline intravenously, and another group received diltiazem, 400 micrograms/kg body wt. Sham animals had no CLP performed. GAC was determined by the D-xylose absorption test at 2 and 4 h after CLP. One hour after the administration of D-xylose via the nasogastric tube, its concentration in portal blood was determined colorimetrically. Results show that GAC is significantly depressed at 2 and 4 h after CLP despite the maintenance of normal blood pressure, central venous pressure, and portal pressure. Administration of diltiazem restored GAC to normal levels at 4 h after CLP. Thus diltiazem is a useful adjuvant in the treatment of sepsis because it restores gut absorptive capacity to normal and allows for early enteral nutrition.

Eight-two bovine Pasteurella haemolytica strains were serotyped. The majority of the strains were isolated from calves which had died from fibrinous pneumonia and small numbers from cases of pleuritis, sepsis and abortion. A total of eight different serotypes were noticed. Serotype A1 was found to be the most prevalent 37.8 per cent, followed by serotype A2 with 20.7 per cent. Antibiotic resistance was found for sulfonamide, tetracycline and penicillin in about half of all strains. Conventional combination of biotype to serotype per strain was not confirmed by the results of arabinose and trehalose fermentation.

Recently, it has become evident that the gut plays a central role in the development of multiple organ failure in the critically ill patient after trauma-hemorrhage and sepsis. However, it remains unknown whether gut absorptive capacity (GAC) is altered under those conditions. The aim of this study, therefore, was to use a rat model for GAC measurements independent of the function of other organs and to determine whether GAC is altered after trauma. Rats (n = 79; 250-325 g) were lightly anesthetized with ether, and a 6-cm midline laparotomy was performed (i.e., trauma induced). A nasogastric tube was inserted and after cannulation of various blood vessels, the animals were allowed to recover from anesthesia. They were then divided into various groups for determinations of GAC over a period of 5 days. Control animals had GAC measurements without any surgery being performed on them. GAC was determined using the 1-h D-xylose absorption test and measuring D-xylose concentration in the portal blood. Results demonstrate that GAC 1) is significantly depressed for the first 48 h after trauma, 2) returns to normal 72 h after trauma, and 3) is further depressed by hemorrhage and resuscitation and by sepsis after trauma. Thus the model described here can be used to investigate the effects of trauma, trauma plus hemorrhage, trauma plus sepsis, hemorrhage alone, and sepsis alone on GAC, independent of the function of other organs.

Radionuclide gastroscopy conducted in patients with vast purulent wounds and sepsis disclosed reduced motor-evacuatory function of the stomach and the rate of its fractional emptying, that supports the necessity of continuous administration of nutrient mixtures by a drip method. A significant improvement of the motor evacuatory function and the rate of fractionated emptying of the stomach, 9-12 days after the commencement of the enteral (tube) nutrition, has shown the necessity of its use at the early stages of the course of severe purulent infection. The investigation of the absorptive capacity of the intestine with the use of the D-xylose test has revealed that it is insignificantly decreased in 82.6% of patients with severe purulent infection, and tube nutrition in such patients could be successfully conducted. Only in 17.4% of the patients the adsorptive capacity of the intestine was significantly decreased, and in these cases predominantly parenteral nutrition was recommended.

An unusual case of Yersinia pseudotuberculosis septicemia is reported. Diabetes mellitus was the sole underlying disease; liver enzyme elevations were only transitory. The strain did not show motility until after 50 days at room temperature; it showed temperature and media-dependent fermentation of arabinose, melibiose and rhamnose.

Although clinical studies suggest enteral, as opposed to parenteral, feeding lowers morbidity and mortality rates following severe trauma and after sepsis, it is unknown whether gut absorptive capacity (GAC) is indeed maintained under such conditions. To study this, GAC was determined in patients with blunt trauma (n = 8) and with sepsis (n = 11) by the 1-hour D-xylose absorption test. Excluded were patients with ileus, nasogastric output of more than 600 mL/24 hours, or residual gastric content of more than 25 mL after the D-xylose test. Trauma patients (ISS 8-14) and patients with intra-abdominal sepsis had an initial D-xylose test within 24 to 48 hours of admission, at 72 to 96 hours, and then weekly until D-xylose absorption had returned to normal. D-xylose (25 g in 200 mL water) was given via nasogastric tube to patients and orally to healthy volunteers (controls: n = 8). Results show that GAC was depressed at 24 to 96 hours in both groups but returned to normal by 1 to 3 weeks after trauma or resolution of sepsis. Thus (1) gut absorptive capacity was severely depressed early after trauma and after the onset of sepsis; and (2) the 1-hour D-xylose absorption test provided a simple, quantitative assessment of GAC in critically ill patients. Hence, therapeutic agents that restore gut absorptive capacity may be useful for further reducing morbidity and mortality rates following trauma or the onset of sepsis.

Agrobacterium species and Ochrobactrum anthropi are generally considered innocuous in clinical settings, yet during the last decade a number of sporadic cases of human infection due to these organisms have been reported. We studied nine cases of infection (septicemia and peritonitis) caused by Agrobacterium-like microorganisms in eight patients. All patients were immunocompromised and had permanent central venous or peritoneal dialysis catheters in place. Seven patients were women, and eight infections were community acquired. Six isolates were identified as Agrobacterium species and three as O. anthropi. These two groups of strains differed in the production of beta-galactosidase and of acid from lactose, erythritol, salicin, and cellobiose. All strains were strictly aerobic, peritrichous, gram-negative bacilli that produced oxidase, urease, and acid from glucose, fructose, arabinose, xylose, mannitol, inositol, and ethanol. The in vitro adherence of isotope-labeled bacteria to silicone tubes was similar to that of staphylococci. We conclude that Agrobacterium species and O. anthropi can be pathogenic in immunocompromised patients with permanent catheters.

Twenty isolates of Pasteurella (Moraxella) anatipestifer from ducks with serositis and septicemia in Thailand between 1988 and 1989 were characterized by various tests. Eighteen isolates fermented glucose and maltose, 3 fructose and 1 each mannose, arabinose, trehalose or sorbitol. All isolates produced gelatinase but not urease, while 2, 3, 5 and 6 produced indole, were CAMP positive, and were proteolytic for milk and coagulated serum respectively. Seven enzymes, phosphatase alkaline, esterase (C4), esterase lipase (C8), leucine arylamidase, valine arylamidase, phosphatase acid and phosphoamidase were detected from all the isolates. The isolates were highly susceptible to ampicillin, erythromycin, penicillin G and tylosin. Gel-diffusion precipitin tests demonstrated that serotype 1 was most prevalent (60%) and serotype 6 followed (5%). Seven isolates (35%) were untypable. These results indicated that P. anatipestifer of serotype 1 played an important role in recent outbreaks of the disease in Thailand.
