Turkish Journal of Veterinary & Animal Sciences
The liver damage and obstructions of the biliary tract were evaluated ultrasonographically in experimentally bile duct ligated dogs. Seven healthy dogs of different breeds were used. The common bile duct was double ligated at the duodenal region after clinical and ultrasonographic examinations. After that, clinical examinations, biochemical analyses and examinations of the liver, gallbladder and biliary tract were done ultrasonographically over 6 weeks. All dogs were necropsied and macroscopic and histologic alterations were determined at the end of the study. It was determined that the levels of serum ALT, ALP, GGT and T. Bilirubin were (p < 0.001-0.05) statistically significantly increased after the operation in all dogs. As a result of ultrasonographic examinations, it was determined that the bile ducts and gallbladder were distended, the neck of the gallbladder was larger and more tortuous than normal, hypoechoic sludge was prominent in the gallbladder, and perivascular, multifocal hyperechoic areas appeared in the liver parenchyma toward the end of the study. These alterations were confirmed macroscopically and microscopically at the end of the autopsy in all dogs. We consider that as well as blood serum parameters, ultrasonographic examinations are useful in the early diagnosis of biliary diseases and in differentiating them from hepatic diseases.

Effects Of Source And Concentrations Of Nitrogen And Carbohydrate On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell
Effects Of Source And Concentrations Of Nitrogen And Carbohydrate On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell
Turkish Journal of Veterinary & Animal Sciences
The objective of this review was to discuss microbial protein synthesis and the effects of sources and concentrations of nitrogen and carbohydrate on microbial protein synthesis. Even though ammonia-N is a satisfactory source of nitrogen for the growth of the majority of rumen microbes, substitution of intact protein for urea usually stimulates ruminal microbial protein synthesis. While protein sources high in degradable intake protein (DIP), such as soybean meal, appear to have properties that optimize microbial protein synthesis, protein sources low in DIP, such as fish meal, appear to limit microbial protein synthesis apparantly because of the low ruminal digestibility …

The Application Of Hypoxanthine Activity As A Quality Indicator Of Cold Stored Fish Burgers, Sühendan Mol, Nuray Erkan, Candan Varlik
Turkish Journal of Veterinary & Animal Sciences
Seafoods are very perishable, and many different methods are used for the determination of their quality. Sensory and hypoxanthine values of cold stored trout burgers, which we prepared, were determined during a 28-day period. Burgers spoiled after the 21st day of storage. The TVB-N values were still very low when the burgers spoiled and the pH values decreased during their storage. Therefore total volatile bases nitrogen and pH analyses were not useful for the determination of the quality of trout burgers. There was a negative correlation between the sensory and the hypoxanthine values during the storage period. Thus, hypoxanthine analysis …

Characterisation Of An Exopolysaccharide Preventing Phage Adsorption In Lactococcus Lactis Subsp. Cremoris Ma39, Mustafa Akçeli̇k, Pinar Şanlibaba
Characterisation Of An Exopolysaccharide Preventing Phage Adsorption In Lactococcus Lactis Subsp. Cremoris Ma39, Mustafa Akçeli̇k, Pinar Şanlibaba
Turkish Journal of Veterinary & Animal Sciences
Lactococcus lactis subsp. cremoris strain MA39 produces an extracellular polysaccharide containing rhamnose, glucose and galactose. A 16.5 kb plasmid encoding exopolysaccharide production in MA39 was determined by plasmid curing experiments. Phage adsorption assays showed that four different lactococcal phages were adsorbed to MA39-40; only the 16.5 kb plasmid cured an exopolysaccharide non-producing mutant of strain MA39, with high efficiency (93.2-98.5%) while adsorption of these phages was completely inhibited in the wild type strain MA39. These results suggest that exopolysaccharide prevents phage adsorption by masking phage receptor sites.
