Bactericidal properties of pradofloxacin against veterinary pathogens.

Pradofloxacin is a new veterinary 8-cyano-fluoroquinolone developed for use against bacterial infections in dogs and cats involving both aerobic and anaerobic bacteria. The minimal bactericidal concentrations have been determined against clinical isolates of Staphylococcus pseudintermedius, Staphylococcus aureus, Escherichia coli, Pasteurella multocida, Streptococcus canis, Proteus spp., Fusobacterium spp.

Activity of pradofloxacin against Porphyromonas and Prevotella spp. Implicated in periodontal disease in dogs: susceptibility test data from a European multicenter study.

Collaborating veterinarians from five European countries collected subgingival bacterial samples from dogs exhibiting clinical periodontal disease. Sterile endodontic paper points were used for collection of the samples, which were transported to a central laboratory for susceptibility testing. Anaerobic bacteria were isolated and Porphyromonas and Prevotella isolates identified to the species level; susceptibility to pradofloxacin and metronidazole was determined using the CLSI agar dilution methodology.

Comparative activity of pradofloxacin against anaerobic bacteria isolated from dogs and cats.

Objectives: To compare the intrinsic activity of pradofloxacin, a new fluoroquinolone developed for use in veterinary medicine, with other fluoroquinolones, against anaerobic bacteria isolated from dogs and cats.

Methods: One hundred and forty-one anaerobes were isolated from dogs and cats and comparative MICs of pradofloxacin, marbofloxacin, enrofloxacin, difloxacin and ibafloxacin were determined according to standardized agar dilution methodology.

Results: Pradofloxacin exerted the greatest antibacterial activity followed by marbofloxacin, enrofloxacin, difloxacin and ibafloxacin.

[Bacteriological and virological status in upper respiratory tract infections of cats (cat common cold complex)].

Between October 2002 and January 2005,460 bacteriological samples from cats with an acute upper respiratory tract infection were analysed in clinical field studies in two accredited laboratories in Germany. Oropharyngeal swabs were taken from these cats and sent to the laboratories for routine diagnostics. In the swab samples of 460 cats 382 bacteria strains were isolated.

The digestion by cattle of silage-containing diets fed at two dry matter intakes. 2. Digestion of total amino acids and of D-alanine and D-glutamic acid.

In a 4 X 4 Latin square experiment four cows were given, twice daily, diets consisting of (g/kg dry matter (DM)) 500 barley, 400 grass silage and 100 soya-bean meal. The diets were given at either 1.15 (L) or 2.

The digestion by cattle of silage-containing diets fed at two dry matter intakes. 1. Digestion of organic matter and nitrogen.

In a 4 X 4 Latin square experiment four cattle were given in two meals per d diets consisting of (g/kg dry matter (DM)) 500 barley, 400 grass silage and 100 soya-bean meal. The diets were given at either 1.15 (L) or 2.

[Nitrogen metabolism in growing swine receiving a bacterial protein supplement (Alcaligenes eutrophus) instead of soybean meal].

In a balance trial with 10 pigs (mean body mass 50 kg) the influence of a bacterial protein supplement (Alcaligenes eutrophus) on N-metabolism was investigated. The bacteria were included into the diet at levels of 7 and 14% at the expense of extracted soyabean meal. Thus bacterial "pure protein" (bacterial non-nucleic acid N X X 6.

[Protein quality of dietary yeast ribonucleic acid studied in growing rats. 2. Effect of ribonucleic acid on N balance and urinary N fractions].

In a balance trial with growing rats the influence of dietary ribonucleic acid (RNA) on N-metabolism was tested. Yeast-RNA was supplied at four levels ranging from 7.8% to 31.

[Protein quality of dietary yeast ribonucleic acid in experiments using growing rats. 1. Effect of ribonucleic acid on the body composition].

In a feeding trial with growing rats the influence of dietary ribonucleic acid on the composition of body gain was investigated. To a control ration with casein + 50% DL-methionine as the sole protein source (1,64 N% in DM) ribonucleic acid (RNA) from yeast was supplemented at four levels ranging from 7,8% to 31,2% of diets nitrogen. The portion of daily feed and nitrogen intake derived from the basal diet was designed to be equal for all the animals.
