Influence of aflatoxin and fumonisin B1-containing culture material on growing barrows.

Aflatoxin (AF)-contaminated and fumonisin B1 (FB1)-contaminated (culture material from Fusarium moniliforme) diets were fed singly and in combination to growing cross-bred barrows. Six barrows (3 replicates of 2 each; mean body weight, 17.5 kg) per group were fed: 0 mg of AF and 0 mg of FB1/kg of feed (control); 2.5 mg of AF/kg of feed; 100 mg of FB1/kg of feed; or 2.5 mg of AF plus 100 mg of FB1/kg of feed for 35 days. The effects on production performance, serum biochemical, hematologic, immunologic, and pathologic measurements were evaluated. Body weight, gain, and feed consumption were sig…

Rhizoxin analogs contribute to the biocontrol activity of a newly isolated pseudomonas strain.

Two strains of Pseudomonas sp., Os17 and St29, were newly isolated from the rhizosphere of rice and potato, respectively, by screening for 2,4-diacetylphloroglucinol producers. These strains were found to be the same species and were the closest to but different from Pseudomonas protegens among the sequenced pseudomonads, based on 16S ribosomal RNA gene and whole-genome analyses. Strain Os17 was as effective a biocontrol agent as reported for P. protegens Cab57, whereas strain St29 was less effective. The whole-genome sequences of these strains were obtained: the genomes are organized into a s

Timosaponin AIII mitigates zearalenone-induced kidney injury in weaned piglets in association with TLR/MAPK signaling suppression.

INTRODUCTION: Zearalenone (ZEN) is a common Fusarium mycotoxin that frequently contaminates feed and can induce kidney dysfunction in pigs. Timosaponin AIII (TSA), a steroidal saponin isolated from Anemarrhena asphodeloides Bunge, possesses anti-inflammatory and antioxidant properties. This study evaluated whether TSA supplementation alleviates ZEN-induced kidney injury in weaned piglets and examined its association with TLR4/MAPK signaling. METHODS: Eighteen weaned female piglets were randomly assigned to three groups (n = 6 per group): Control (basal diet), ZEN (basal diet supplemented with…

Perceptions of Fungal Contamination in Hospital Humidifiers Among Healthcare Providers in Jordan: A Cross-Sectional Study.

BACKGROUND: Hospital-acquired infections remain a critical concern globally. Fungal contamination of reusable hospital humidifiers, especially in intensive care units (ICUs), represents an under-recognized threat. These devices, if improperly maintained, may become reservoirs for opportunistic pathogens such as Aspergillus and Fusarium, thereby compromising patient safety. OBJECTIVE: The objective of this study is to explore the perceptions of fungal contamination in hospital humidifiers across Jordan and describe associated disinfection practices, protocol presence, and staff awareness, with…

Emerging infections in burns.

BACKGROUND: Patients who suffer severe burns are at higher risk for local and systemic infections. In recent years, emerging resistant patho … nephrotoxicity. The main fungal pathogens in burn patients are Candida spp., Aspergillus spp., and Fusarium spp. A definitive diagnosis is more difficult to obtain than in bacterial infections. Amphotericin B and voriconazole remain the two most important anti-fungal substances in our practice. CONCLUSIONS: Innovations in fluid management, ventilatory su …

Occurrence of anabolic agents in plants and their importance.

More than 40 plant species have been shown to contain substances that are active in biological assays for estrogenic activity. Such substances may be constitutive metabolic products of a plant, or be formed adaptively in response to environmental factors, such as fungal attack (e.g. coumestrol synthesis in alfalfa infected with Pseudopeziza medicagensis); in other instances estrogens may arise from microbial attack on plant material during storage (e.g. zearalenone formation from corn by Fusarium spp.) Phyto-estrogens may reach man through direct consumption of fresh fruit, vegetables and proc…

Effects of zearalenone on in utero development in rats.

Zearalenone (ZE), an estrogenic mycotoxin produced by Fusarium graminearum or F. roseum, is one of the most common contaminants of cereal grains world-wide. The objective of this study was to determine the effects of ZE on in utero development of rats. Pregnant female Charles River Sprague-Dawley rats were gavaged once daily with ZE (in corn oil) at doses of 0, 1, 2, 4, or 8 mg/kg body weight on gestation days (GD) 6-19. All females survived to cesarean section on GD 20. At cesarean section, reproductive and developmental parameters were measured and blood was taken for hormone analysis. Dose-…

Characterization of fumonisin toxicity in orally and intravenously dosed swine.

Fumonisin B1 (FB1), a recently identified mycotoxin produced by Fusarium moniliforme in corn, has been shown to cause death in swine due to pulmonary edema, an apparently species specific effect, and to interfere with sphingolipid metabolism in vitro. Here we characterize the toxicity of fumonisins, using female cross-bred swine weighing 6 to 13 kg, and present a hypothesis regarding the mechanism of fumonisin-induced pulmonary edema in swine. FB1 was given daily intravenously (IV) to pig 1 for 9 days for a total of 72 mg (7.9 mg/kg) and to pig 2 for 4 days for a total of 67 mg (4.6 mg/kg). Pi…

Selective sequestration of STAT1 in the cytoplasm via phosphorylated SHP-2 ameliorates murine experimental colitis.

The side effects of current immunosuppressive drugs have impeded the development of therapies for immune diseases. Selective regulation of STAT signaling is an attractive strategy for treating immune disorders. In this study, we used a small-molecule compound to explore possible means of targeting STAT1 for the treatment of Th1-mediated inflammation. Selective regulation of STAT1 signaling in T cells from C57BL/6 mice was accomplished using fusaruside, a small-molecule compound that triggers the tyrosine phosphorylation of Src homology 2-containing protein tyrosine phosphatase 2 (SHP-2). The i
