Lipid contents and fatty acid profiles in the commercial microdiets for farming marine fish species were determined. Twenty microdiet samples were taken from marine fish farms on the Aegean region of Turkey throughout 2006-2007. Of the 20 microdiet samples, 5 were produced in Turkey and 15 were imported. The fatty acid analysis of the microdiets was made by gas-liquid chromatography using helium as the carrier gas. The lipid levels of the microdiets produced in Turkey by different companies ranged from 9.5 ± 0.05% to 11.6 ± 0.14% (P < 0.05). In contrast, the lipid levels of imported microdiets were between 10.6 ± 0.20% and 17.2 ± 0.14% (P < 0.05). n-3 polyunsaturated fatty acids (n-3 PUFA) levels in the microdiets ranged from 7.1 ± 0.03% to 24.8 ± 0.03% of total fatty acids (P < 0.05). Similarly, n-3 highly unsaturated fatty acid (n-3 HUFA) levels in the microdiets ranged from 6.1 ± 0.01% to 22.8 ± 0.02% of total fatty acids (P < 0.05). n-3 highly unsaturated fatty acids (n-3 HUFA) levels in the microdiets were found between 0.6 ± 0.00% and 3.6 ± 0.01% of dry weight of diets (P < 0.05). Docosahexaenoic acid (DHA) levels of these microdiets were between 0.3 ± 0.00% and 2.0 ± 0.03% of the dry weight of diets (P < 0.05). Eicosapentaenoic acid (EPA) levels in the dry weight of diets were between 0.3 ± 0.01% and 2.2 ± 0.01% (P < 0.05).

Structural Aberration In Ha Associated With Adaptation Of Human Influenza A H3n2 Virus In Embryonated Chicken Eggs, Viroj Wiwanitkit
Structural Aberration In Ha Associated With Adaptation Of Human Influenza A H3n2 Virus In Embryonated Chicken Eggs, Viroj Wiwanitkit
Turkish Journal of Veterinary & Animal Sciences
Molecular changes associated with adaptation of human influenza A virus in embryonated chicken eggs are reported: 4 amino acid substitutions occurred in HA (G186V, S219F, V226I, V309I). These substitutions allowed binding to SAalpha2,3Gal- and SAalpha2,6Gal-containing receptors, conferred SAalpha2,3Gal specificity, and preserved antigenicity. Here, the author reports the result of protein secondary structure predictions of the adaption from its primary sequence using the NNPREDICT server. Comparing the classical HA of H3N2, the adaptation has additional helices and strands and these identified structural changes should be the explanation for the reported binding and antigenicity changes.

In a retrospective study on cytological specimens from 17 dogs with histologically confirmed cutaneous squamous cell carcinoma, the morphometric variables were studied and compared to tumors' nuclear grade. The morphometric parameters evaluated in this study were mean nuclear area (MNA, µm2), mean nuclear perimeter (MNP, µm), mean nuclear diameter (D mean, µm), minimum nuclear diameter (D min, µm), and maximum nuclear diameter (D max, µm). Associations between MNA, MNP, D mean, D min, and D max and tumors' grade were assessed using the ANOVA/LSD test (Statistica 6.0, StatSoft, USA) at a level of significance of P < 0.05. The result indicated an increase in the mean values of the nuclear parameters with increasing tumor grade. In the cases examined, significant differences in MNA, MNP, and D mean occurred between tumors in all grades. Besides, no significant differences in D max (between grade I-II and II-III) and D min (grade II-III) were found. In conclusion, nuclear morphometry could be used as an additional tool for differentiating nuclear grade in canine cutaneous squamous cell carcinomas.

In the present study, an ileal leiomyoma encountered in a captive zebra (Equus burchelli) was reported. A 29-year-old, female zebra was found dead in the Bursa zoo. According to the referring veterinarian the most prominent clinical signs were intermittent colic (responsive to analgesics) and constipation. At post mortem examination, abdomen was severely distended. A firm, multilobular, well vascularized and encapsulated tumoural mass, 12 cm in diameter, embedded into the proximal part of the ileum wall, and protruded from the serosal surface was found. The cut section of the mass had whorled appearance, pale yellow to white in colour, and had …

LSU Doctoral Dissertations
Rickettsia felis is a gram-negative bacterium predominantly described in the cat flea, Ctenocephalides felis. Since first described in 1990 in a commercial cat flea colony in the United States, R. felis has been detected in numerous arthropod species in 28 countries around the world. Additionally, as the etiologic agent of flea-borne rickettsiosis, R. felis can cause disease in humans, with patients presenting with clinical symptoms typical of rickettsial diseases including: fever, headache, and myalgia. Transmission of R. felis within flea colonies is predominantly via vertical (transovarial and transstadial) transmission and mechanisms of horizontal transmission are undescribed. Studies are needed to …

Equine Herpesvirus-1 (EHV-1) is an important ubiquitous enzootic equine pathogen, causing significant economic losses to the horse industry. Despite extensive vaccination protocols, EHV-1 continues to be a major cause of epidemic abortion, perinatal mortality, respiratory disease and neurologic disease. EHV-1 infections are usually dealt with by using management practices that limit spread of the disease and secondary complications, providing symptomatic relief to infected horses, but no specific treatment is available. New therapeutic or virucidal agents could have great utility in slowing both the progression and spread of the disease in an epidemic situation. A number of porphyrins and their derivatives …
