Aim:The present study was conducted to ascertain the prevalence of common digestive problems compared to other health problems among dogs that were admitted to the teaching veterinary hospital, faculty of veterinary medicine, Cairo University, Egypt during 1 year period from January to December 2013. Also, study the effect of age, sex, breeds, and season on the distribution of digestive problems in dogs.Materials and Methods:A total of 3864 dogs included 1488 apparently healthy (included 816 males and 672 females) and 2376 diseased dogs (included 1542 males and 834 females) were registered for age, sex, breed, and the main complaint from their owners. A complete history and detailed clinical examination of each case were applied to the aids of radiographic, ultrasonographic, and endoscopic examination tools. Fecal examination was applied for each admitted case. Rapid tests for parvovirus and canine distemper virus detection were also performed.Results:A five digestive problems were commonly recorded including vomiting, diarrhea, concurrent vomiting with diarrhea, anorexia, and constipation with a prevalence (%) of 13.6, 19.1, 10.1, 13.1, and 0.5 respectively while that of dermatological, respiratory, urinary, neurological, cardiovascular, auditory, and ocular problems was 27.9, 10.5, 3.3, 0.84, 0.4, 0.25, and 0.17 (%) respectively. This prevalence was obtained on the basis of the diseased cases. Age and breed had a significant effect on the distribution of digestive problems in dogs (p<0.001). Gender had an effect on the distribution of digestive problems with significant (p≤0.01) while season had a non-significant effect (p>0.05) on the distribution of such problems.Conclusion:Digestive problems were the highest recorded problems among dogs, and this was the first records for such problems among dogs in Egypt. Age, gender, and breeds had a significant effect on the distribution of the digestive problems in dogs while season had a non-significant effect on the distribution of such problems. The present data enable veterinarians in Egypt to ascertain their needs for diagnostic tools and medication that must be present at any pet clinic.

Background and Aim: One of the most common cutaneous infections seen in veterinary canine practice is canine demodicosis. Demodicosis is a parasitic skin infection with a possible impact on acute-phase proteins (APPs) and oxidant-antioxidant balance. This study aimed to estimate the possible alterations in hematological, biochemical, oxidant-antioxidant, and APP (C-reactive protein [CRP] and albumin) profiles in naturally infected dogs with demodicosis. Materials and Methods: This study enrolled 21 dogs that were divided into two groups: The control group including 7 apparently healthy dogs and the diseased group including 14 dogs with generalized demodicosis. Demodicosis was confirmed through microscopic detection. Blood samples were collected for the estimation of CBC, total protein, albumin, alanine transaminase, aspartate aminotransferase, blood urea nitrogen, creatinine, superoxide dismutase (SOD), glutathione peroxidase (GPx), total antioxidant capacity (TAC), catalase (CAT), malondialdehyde (MDA), and CRP levels. Results: Significant reduction in red blood cells along with significant elevation in white blood cells was recorded in the diseased group compared with the control group. There was also significant elevation in MDA, TAC, SOD, and CRP levels along with significant reduction in GSH-Px and CAT levels in the diseased group. Conclusion: Based on these findings, a relationship between canine generalized demodicosis and oxidant-antioxidant disequilibrium could be suggested. Evidence of this relation manifested in the elevation in MDA and SOD levels and reduction in GPx and CAT levels as a consequence to the release of ROS resulting from Demodex infection. CRP elevation is expected in canine demodicosis.

Sarcoptic mange is a common, zoonotic and important disease facing camel farming systems with grave economic losses. The present study was applied to estimate the effect of sarcoptic mange on clinical condition, hematobiochemical criteria and trace-element status among camels in Egypt. A total number of thirty dromedary camels (Camelus dromedarius) were investigated in the present study. The animals were divided into fourteen diseased camels affected with sarcoptic mange and sixteen apparently healthy camels. Complete case history and clinical examination included respiration, pulse rates and body temperature was applied. The main clinical manifestations included over thickening of the skin with scales, fissuring, intense itching, unthriftiness, weight loss, and debility. Clinical examination showed significant increase (P≤0.05) and (P≤0.01) for respiration and pulse rates respectively in affected camels. Hematological analysis in diseased camels showed a significant decrease in PCV (P≤0.05), Hb (P≤0.001), RBCs count (P≤0.01), MCHC (P≤0.001) and relative (%) lymphocytic level (P≤0.001) while significant increase was recorded for MCV (P≤0.01), TLC (P≤0.01), relative (%) neutrophils (P≤0.001) and eosinophils levels (P≤0.01). Results of biochemical constituents in affected camels showed a significant decrease (P≤0.001) in total protein, albumin, glucose and zinc levels while A/G ratio showed significant (P≤0.01) decrease. Both serum total iron and copper levels showed a significant (P≤0.05) decrease in diseased camels compared to healthy camels. Skin swab samples revealed Staphylococcus spp. in the majority of mange infected cases indicating secondary pyoderma. In conclusion, sarcoptic mange had a deleterious effect on physical, hematobiochemical condition and trace-element status in camels.
