Dermatitis Solaris and Its Treatment in Van Cats
(indian veterinary Journal, 2006) Karaca, Mehmet; Tutuncu, Mehmet; Akkan, Hasan Altan; Yuksel, Hayati; Keles, Ihsan; Agaoglu, Zahid
Dermatitis solaris is a skin disease of light coloured cats and dogs seen in summer season. The disease occurs especially on the unpigmented areas such as tip of the ears, nose, body and extremities as a result of phototoxic reactions when subjected to ultraviolet lights. The disease has been reported to come into view as chronic dermatitis in cats having white ear and blue eyes. (Haziroglu and Milli, 1998). The pathogenesis of feline dermatitis is thought to occur as a result of free radicals released after phototoxic reactions (Soter, 1990).
An Investigation on Serum Troponin Concentration in Healthy Ruminants
(Kafkas Univ, veteriner Fakultesi dergisi, 2010) Basbugan, Yildiray; Agaoglu, Zahid; Yuksek, Nazmi
The present study aimed to investigate the cardiac troponin (cTn I and cTn T) levels in healthy ruminants. The study involved 30 cattle (15 male, 15 female), 30 Akkaraman sheep (15 male, 15 female) and 30 goats (15 male, 15 female) and all animals were clinically healthy. The study animals were grouped as 0-6 months, 6-12 months and 12 months and over. Blood samples were obtained from jugular vein and cardiac troponin I and T levels, and biochemical parameters (CK, CK-MB, AST and LDH) were measured. Troponin T values were found as negative in all three species. Troponin I values were 0-0.23 ng/ml (mean 0.18 ng/ml) in cattle, 0-0.21 ng/ml (mean 0.15 ng/ml) in sheep and 0-0.24 ng/ml (mean 0.20 ng/ml) in goats. It was also found that the values were in declared limits for cattle and sheep. Although CK, CK-MB, AST and LDH values were in normal ranges AST levels were higher in cattle and sheep of 0-6 months of age and, LDH levels were higher in sheep and goat at 6-12 months of age. In conclusion, obtained troponin values in this study could be values for healthy ruminants.
The Occurrence and Antibiotic Resistance of Motile Aeromonas in Livestock
(Springer, 2009) Ceylan, Ebubekir; Berktas, Mustafa; Agaoglu, Zahid
The present study was carried out to assess the prevalence of motile Aeromonas spp. in the faeces of clinically healthy sheep, cattle and horses and evaluate their susceptibility to some anti-microbial agents. Rectal swabs from 120 sheep, 85 cattle and 20 horses were examined for Aeromonas species using alkaline peptone water (pH 8.4) as the enrichment medium and Aeromonas Selective Agar containing 5 mg/l ampicillin as the isolation medium. Identification and antibiotic resistance of motile Aeromonas strains was performed using Gram Negative Enteric ID panel. Motile aeromonads were isolated from 12 (10%) sheep, 7 (8.2%) cattle and 1 (5%) horse. Of these 20 aeromonad isolates, 13 were A. caviae, 6 were A.sobria and 1 was A. hydrophila. Aeromonas species in the faeces of livestock might pose a public health problem for humans who are in direct contact with contaminated animals. However, further studies should be performed on aeromonads relating to their transmission between animals and humans.
Serum Adenosine Deaminase Activity in Domestic Animals: Reference Values
(Tubitak Scientific & Technological Research Council Turkey, 2009) Altug, Nuri; Yuksek, Nazmi; Agaoglu, Zahid; Keles, Ihsan
This study was aimed to determine normal serum adenosine deaminase (ADA) activity in domestic animals in both sexes and that were considered healthy on the basis of clinical and laboratory examinations. In this study, 262 non-pregnant animals of both sexes, belonging to 5 species [cattle (n = 50), sheep (n = 65), goat (n = 52), dog (n = 55), and cat (n = 40)] were used. Serum total ADA and ADA1 isoenzyme activities were found to be 6.34 +/- 0.31 IU/l and 6.34 +/- 0.31 IU/l in cattle, 7.57 +/- 0.30 IU/l and 7.31 +/- 0.47 IU/l in sheep, 7.52 +/- 0.36 IU/l and 6.44 +/- 0.72 IU/l in goat, 2.56 +/- 0.13 IU/l and 2.03 +/- 0.30 IU/l in dogs, 23.36 +/- 1.59 IU/l and 21.71 +/- 2.13 IU/l in cats, respectively. The serum levels of ADA2 were low in sheep, goats, dogs, and cats, whereas in these species ADA1 was high. Furthermore, there was no serum ADA2 activity in cattle. Additionally, there were no significant differences between genders in ADA activities in all species. As a result, determination of serum normal ADA and its isoenzyme activities in domestic animals will be useful for scientists who want to investigate ADA activity in future in different diseases.
