Koi herpesvirus disease (KHVD) is a highly contagious viral illness causing significant morbidity and mortality in common carp (Cyprinus carpio). KHVD has been confirmed in almost all countries around the world except Australia. KHV has been previously detected in the Czech Republic based on PCR screening but with no clinical signs of KHVD. An outbreak of KHVD with clinical signs, and severe mo...

There is growing evidence that Enterobacteriaceae harboring clinically relevant bla genes, especially genes encoding the CTX-M family of extended-spectrum -lactamases (ESBLs), have spread into the environment (1). The purposes of this study were (i) to investigate the occurrence of expanded-spectrum-cephalosporinresistant Enterobacteriaceae in intestines of fish captured from Lake Zürich and La...

The electrochemical and photoelectrochemical behavior of n-type silicon electrodes coated with noble metal silicides and RuO, in aqueous solutions containing various redox couples was investigated. Iridium silicide coated n-Si electrodes, n-Si( Ir), and Ru02-modified n-Si(1r) electrodes can photogenerate 12, Brz, and C12 with high stability and efficiencies (>5%) . The photooxidation of water o...

Introduction: Spinal cord (SC) is a site of predilection of multiple sclerosis (MS) lesions and its pathology contributes substantially to disability. Previous DTI studies of the SC in MS patients showed significant decrease in fractional anisotropy (FA) compared to healthy controls in both lesions and normal-appearing tissue. However, in gray matter (GM), DTI measurements might be of limited u...

WillomitzerJ J.: Seasonal Dynamics of Parasitoses in Grasscarp (Utenopharyngodon idella) Fry and Fingerlings. Acta vet. Brno, 49, 1980: 269 277. Examination of grasscarp (Ctenopharyngodon idella) fry and fingerlings from the State Fishery, Pohorelice, for 3 years revealed grasscarp infestation with 12 parasite genera or species. The intensity and extensity of infestation was highest in the peri...

Routine screening of rainbow trout and other non-salmonid fish species from traditional pond farms in Lower Saxony, Germany, indicated a low incidence of cataract and other optical changes. The cataract problem and more severe eye changes, although present in freshwater fish farming, seem to be less prevalent than in marine production of Atlantic salmon. Cataracts have been a subject of increas...
