During a 20-month period all acute nonlymphocytic patients (87 patient trials) receiving cytotoxic chemotherapy were placed on an oral nonabsorbable antibiotic regimen consisting of gentamicin, vancomycin, and nystatin in addition to an intensive program of infection prevention aimed at reducing exogenously acquired and body-surface potential pathogens. Although side effects of anorexia, diarrhea, and nausea were common, gentamicin-vancomycin-nystatin was ingested 80% of the study time. Microbial growth in gingival and rectal cultures was substantially reduced. The incidence of bacteremias and other serious infections was low. Pseudomonas aeruginosa, other gram-negative bacilli, and Candida species caused few infections along the alimentary canal, whereas infections of the skin (especially Staphylococcus aureus) were not reduced compared with those occurring in former years. A total of the 104 acquired gram-negative bacilli were gentamicin resistant; 5 subsequently caused infection. Thus, despite certain definite drawbacks, the use of oral nonabsorbable antibiotics to suppress alimentary tract microbial flora in combination with other infection prevention techniques in granulocytopenic cancer patients has proven feasible and tolerable and has been associated with a low order of life-threatening infections.

The outbreak of the disease occurred in a large multiple-age farm with about 50,000 meat turkeys, where groups of 6-8000 one-day-old birds were stalled up every 14 days. All the turkey poults housed were affected mostly in the 1.-3. week of the life. The respiratory disease spread rapidly within the flocks and were characterised clinically by inclination of huddle, ruffled feathers, anorexia, stunted growth, swelling of the infraorbital sinus and nasal discharge. The clinical apparent disease lasted 3 to 4 weeks on the average in the affected flocks and were associated with a mortality from 7-20 percent. The main pathoanatomical lesions were catarrhal-fibrinopurulent rhinitis, sinusitis, tracheitis, bronchopneumonia and air sacculitis as well as atrophy of the thymus. Fibrinous adhesive peri- and epicarditis, perihepatitis, miliary necrotic foci in the liver and diarrhea have been found less frequently. The results of cultural and serological examinations of moribund and dead turkey poults of 6 different flocks indicate that Bordetella avium and Chlamydia psittaci are the primary inciting agents of the respiratory disease. However, the following severe course of the disease were mainly caused by concurrent infections with Klebsiella pneumoniae subsp. pneumoniae, Escherichia coli and Pseudomonas fluorescens. In some cases coccidiosis with lesions in ceca were additionally diagnosed. Campylobacter jejuni could be always isolated culturally from the liquid cecal content of diseased birds.

Candida albicans urocystitis secondary to urethral stricture and administration of antibiotics was diagnosed in a cat by fungal culturing of urine and examination of specimens. Surgical repair of the stricture and administration of 5-fluorocytosine resulted in resolution of the cystitis. Related problems included anorexia and severe weight loss, which necessitated enteral nutritional support, dehydration, renal disease, and nosocomial Pseudomonas aeruginosa urocystitis.

Skeletal muscle changes associated with severe injury were investigated in male Wistar rats subjected to 30% full thickness scald injury (burn) and thermal injury followed by immediate colonization with 10(8) colony-forming units of Pseudomonas aeruginosa (BI). Freely fed animals (FF) and animals pair fed to the BI animals (PF) served as controls. Thermal injury in conjunction with infection produced a rapid and sustained muscle cellular membrane depolarization (transmembrane potential difference at 12 h after injury: FF 92.1 +/- 0.3 and BI 85.2 +/- 2.3 mV; P less than 0.05). This was followed by body weight loss and skeletal muscle protein wasting (gastrocnemius protein at 7 days: FF 0.35 +/- 0.01 and BI 0.16 +/- 0.03 g; P less than 0.05) and intracellular high-energy phosphate depletion (ATP at 10 days: FF 6.6 +/- 0.4 and BI 4.5 +/- 0.4 mumol/g tissue; P less than 0.05). These body and cellular changes were not accounted for by the anorexia alone. Marked alterations in intracellular free amino acids were also noted in the BI group characterized by increases in levels of all amino acids (total intracellular free amino acids at 7 days: FF 51 +/- 7 and BI 91 +/- 12 mM; P less than 0.05) except intracellular glutamine (at 7 days: FF 6.0 +/- 0.2 and BI 2.4 +/- 0.6 mM; P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Thermal injury is associated with functional alterations of multiple organ systems, including the gastrointestinal tract. To study the effects of ongoing infection after thermal injury on bowel mass, composition, and blood flow, male Wistar rats were randomized to receive either 30% scald burn, 30% scald burn with Pseudomonas aeruginosa wound inoculation, sham burn, or sham burn with pair feeding to burned and infected animals. On days 3 and 7 after injury, intestinal blood flow was measured with 51Cr-labeled microspheres, and intestinal mass and composition were analyzed. Burned and infected animals demonstrated a chronic loss of small bowel mass not seen in burned animals without infection by day 7 after injury. Compositional alterations of the small bowels of burned and infected animals included protein wasting similar to but occurring earlier than that seen with anorexia alone and significantly decreased deoxyribonucleic acid and ribonucleic acid content, whereas tissue water content remained unchanged. These chronic intestinal alterations in the burned and infected group could not be explained by ongoing ischemia because intestinal blood flow in these animals was not significantly altered at either time point, implying mediation by other pathophysiologic mechanisms.

Patients with cystic fibrosis suffer from a chronic, progressively destructive bronchitis characterized by colonization of the airways by Pseudomonas aeruginosa. Cell wall lipopolysaccharides from P. aeruginosa may stimulate secretion of cytokines such as tumor necrosis factor alpha (TNF alpha) by monocytes/macrophages. We found elevated levels of TNF alpha (150 +/- 60 pg/ml), interleukin-1 alpha (144 +/- 205 pg/ml), and interleukin-1 beta (62 +/- 100 pg/ml) in plasma from 25 patients with cystic fibrosis. In patients with less advanced disease, elevated plasma levels of TNF alpha correlated with high levels of complexes between neutrophil elastase and alpha 1-proteinase inhibitor, suggesting that TNF alpha may be a mediator of neutrophil degranulation. TNF alpha, by its chemotactic effect on neutrophils, may also contribute to the massive influx of neutrophils into and around the bronchial tree. Our findings raise the questions whether in patients with cystic fibrosis TNF alpha acts as cachectin and whether it mediates the anorexia that often results in weight loss.

The effects in goats of the subcutaneous injection of varying doses of Pseudomonas pseudomallei (90 to 500,000 bacilli) suspended in normal saline are described. High doses (greater than or equal to 500 bacilli) caused acute, fatal infections. Lower doses (90 to 225 bacilli) caused acute or chronic disease when infection became established. However, 11 of 18 goats injected with the lower doses of bacilli showed no sign of infection on clinical or bacteriological examination. Response to antibiotic therapy with long acting tetracycline and chloramphenicol was minimal. Goats surviving the initial phase of infection tended to overcome the disease with a corresponding increase in the number of abscesses that were sterile at necropsy. In infected goats, clinical signs included undulating fever, wasting, anorexia, paresis of the hind legs, severe mastitis and abortion. At necropsy, abscesses were found predominantly in the spleen, lungs, subcutaneous injection site and its draining lymph node.

Cachexia and anorexia commonly occur in patients with cystic fibrosis (CF), particularly those with severe pulmonary compromise and heavy tracheobronchial colonization with Pseudomonas aeruginosa. Current understanding of the pathophysiology of cachexia attributes much of the anorexia and weight loss to the effects of the cytokine tumor necrosis factor (TNF), which is secreted by endotoxin-stimulated macrophages. It has further been suggested that TNF may play a role in the pathobiochemistry of CF cachexia, secondary to the localized inflammatory response in the lung or wider systemic activation of cells of the monocyte-macrophage series in response to endotoxin. This study investigates TNF production and gene expression by peripheral blood monocyte-derived macrophages from CF patients, compared with normals (NL). The results indicate that although both cell populations responded dose-dependently to lipopolysaccharide (LPS); CF macrophages, upon stimulation with LPS at concentrations of 1 to 1,000 ng/ml, consistently produced substantially higher amounts of TNF than NL macrophages. At the molecular level, Northern blot analysis also revealed that both macrophage populations expressed TNF mRNA in response to LPS in a dose-dependent manner. However, at the same LPS concentrations, CF macrophage TNF mRNA expression was 2- to 4-fold greater than that of NL macrophages. LPS had no effect in either macrophage population on mRNA for CHO-B, a constitutive probe. To investigate differences between NL and CF macrophage TNF regulation, nuclear run-on/half-life studies as well as studies addressing potential differences in LPS membrane interactions and signal transduction were performed.(ABSTRACT TRUNCATED AT 250 WORDS)

This report describes a case of Pseudomonas aeruginosa infection in a chinchilla. The affected animal displayed a variety of clinical signs including genital swelling, conjunctivitis, anorexia, weight loss, corneal and oral ulcerations and, most unusually, intradermal pustules which developed 8 days after recovery from the initial illness. The occurrence of these pustules has not been documented previously.

Hylesia metabus larvae are susceptible to several pathogens indigenous to the area in which they are found. Some larvae show symptoms characteristic of bacterial infection; they become flaccid and lethargic, and show a marked loss of appetite. We isolated and identified 29 bacterial strains from live, dead and experimentally infected H. metabus larvae, and evaluated their pathogenic activity. The bacteria which caused mortality in the larvae were: Pseudomonas aeruginosa (60-93.3%), Proteus vulgaris (20%), Alcaligenes faecalis, Planococcus sp. and Bacillus megaterium (10%), at doses of 3-4 x 10(7). Although P. aeruginosa is a well-known insect pathogen, this is the first report of its pathogenic activity on H. metabus. The potential risk to humans and low virulence make it unlikely that P. aeruginosa could be used in an augmentative biological control programme. However its natural incidence may be enhanced using parasites and predators of H. metabus as carriers.
