Zearalenone (ZEA) is a common food contaminant (ppb-ppm) derived from Fusarium fungi. With its estrogenicity and potential chronic exposure, ZEA poses a risk to pregnancy. Our previous studies implied post-implantational lethality by ZEA. Since a functional placenta is essential for fetal
One culture ofF avenaceum, 4 cultures ofF oxysporum, and 11 cultures of Fsambucinum were isolated from soil samples of pasture in New Zealand in 1987. All cultures, when grown on rice media and fed to rats caused a weight loss in rats as well as toxic signs including hemorrhaging and congestion,
Three isolates ofGibberella zeae, the perfect stage ofFusarium graminearum, were isolated from ground corn cultures obtained from Taiwan in 1985 and identified asGibberella zeae l-1, G. zeae I-5, andG. zeae l-7. The isolates were grown on a solid rice medium and extracts prepared with 75% aqueous
Fifty-five Fusarium isolates belonging to nine species were collected from fungus-invaded tissue of stored sugar beets and identified as F. acuminatum (11 isolates), F. avenaceum (1 isolate), F. culmorum (1 isolate), F. equiseti (23 isolates), F. graminearum (4 isolates), F. oxysporum (1 isolate),
Thirty-four isolates of Fusarium moniliforme were obtained from cereal grains collected in various parts of the world. The isolates were grown on rice and tested as a diet for toxicity to rats. Of these isolates, 53% caused death, 12% caused congestion and hemorrhage of the stomach and intestine as
Mycotoxins were detected in 13 out of 131 feed samples examined over two years. Screening of feeds associated with cases of suspected mycotoxicosis occurring in farm animals over a further 12 month period showed that most incidents occurred during the winter and involved mainly cattle and pigs fed
The estrogenic activity of ginseng has been the subject of conflicting reports. Cell proliferation, induction of estrogen-responsive genes, and isolated cases of adverse reactions such as postmenopausal vaginal bleeding and gynecomastia have been reported after ginseng treatment. Other studies
Congenital testicular tumours are seldom reported in bovine species. This case report describes the clinical, sonographical, haematological, pathomorphological and immunohistological features of a Sertoli cell tumour in a neonatal German Holstein calf. Microscopically, the enlarged testicle was
Sixty-two isolates of Fusarium were obtained from pasture grass and soil from various areas of New Zealand and identified as F. anthophilum, F. avenaceum, F. crookwellense, F. culmorum, F. graminearum, F. nivale, F. oxysporum, F. sambucinum, F. semitectum, F. tricinctum and an unidentified Fusarium
Thirty-nine isolates of fungi obtained from foodstuffs and soil samples from various parts of the world have been identified. The isolates were grown on a solid rice medium, and extracts were prepared with 50% aqueous methanol. The extracts were examined for toxicity in the following systems: (i)
Twenty-five isolates of F. acuminatum, 38 of F. avenaceum, 1 of F. culmorum, 31 of F. oxysporum and 56 of F. sambucinum were obtained in 1983, 1984 and 1986 from cereal grains and soil from various parts of Norway. The isolates were grown on an autoclaved Uncle Ben's parboiled rice medium and
Respiratory infections, recurrent airway obstruction (RAO) and exercise induced pulmonary haemorrhage (EIPH) are major causes of poor performance in horses. Fungi and mycotoxins are now recognised as a major cause of these conditions. The most notable fungi are Aspergillus and Fusarium. Fungal
Mass spectrometric techniques are essential for advanced research in food safety and environmental monitoring. These fields are important for securing the health of humans and animals, and for ensuring environmental security. Mycotoxins, toxic secondary metabolites of filamentous fungi, are major
