Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major conc...

Sir, The Gram-negative bacterium Haemophilus parasuis is the causative agent of Glässer’s disease, which is characterized by various combinations of meningoencephalitis, polyserositis, polyarthritis and bacterial pneumonia, resulting in major economic losses to the swine industry worldwide. Florfenicol is used exclusively in veterinary medicine and was approved for the treatment of porcine resp...

Challenge models generating gill lesions typical for columnaris disease were developed for the fry of both Common Carp Cyprinus carpio and Rainbow Trout Oncorhynchus mykiss by means of an immersion challenge and Flavobacterium columnare field isolates were characterized regarding virulence. Carp inoculated with highly virulent isolates revealed diffuse, whitish discoloration of the gills affect...

The purpose of this study was to compare the efficacy of a new combination drug, florfenicol-flunixin meglumine, with tulathromycin for initial treatment of undifferentiated fever (UF) in fall-placed calves that received metaphylactic tilmicosin on arrival at the feedlot. No significant differences were observed in UF relapses between the two drugs. Calves treated with florfenicol-flunixin had ...

The antibiotic residues in milk are a well-known serious problem and pose several health hazards to consumers. We have described a simple, rapid, and inexpensive DLLME-HPLC/UV technique for the extraction of chloramphenicol and florfenicol residues in milk samples. Under the optimum conditions, linearity of the method was observed over the range 0.02-0.85 µg/L with correlation coefficients > 0....

Although once popular prior to the last century, the aquaculture of crucian carp Carassius carassius (L. 1758) in Sweden gradually fell from favour. This is the first genetic comparison of crucian carp from historic man-made ponds in the Scandinavian Peninsula. The aim was to identify old populations without admixture and to compare the relationship of pond populations from different provinces ...

Biological Trace Element Research 34(3): 225-236. Acute and chronic toxicity tests for malathion, diazinon, copper (Cu), mercury (Hg), lead (Pb), zinc (Zn), nickel (Ni), and iron (Fe) were conducted. Mortalities of Barilius vagra and Cyp...

Carp interstitial nephritis and gill necrosis virus (CNGV) is an unclassified large DNA virus that morphologically resembles members of the Herpesviridae but contains a large (ca. approximately 280-kbp) linear double-stranded DNA. This virus has also been named koi herpesvirus, koi herpes-like virus, and cyprinid herpesvirus 3. CNGV is the cause of a lethal disease that afflicts common carp and...
