Hematobiochemical studies on sarcoptic mange in camel (Camelus dromedarus) in Banaskantha district (North Gujarat)
... The striking decrease in the percentage and amounts of red blood cells in circulating blood as well as the quantities of hemoglobin suggests an anemic condition. This outcome is quite similar to other findings of anemia in mangy rabbits (Arlian et al. 1988), mangy camels (Parmar et al. 2005), mangy goats (Ujjwal and Dey 2010), and mangy sheep (Hafeez et al. 2007). On the other hand, Sharma (Sharma et al. 1990) and Hafeez (Hafeez et al. 2007) reported that the anemic condition observed in mite infestation is consequent upon the blood sucking activity of the mite and the decreased cellular content in the blood after infestation. ...
The clinicopathological features including mineral level of dogs infested with Sarcoptes scabiei var. canis were evaluated to understand the pathogenesis of infestation in order to propose an effective treatment plan. Twenty healthy dogs were recruited for the study and were divided into two groups after environmental adjustments. Group A dogs were scabies free while group B dogs were housed with scabies infested dogs. The PCV, HB, RBC, WBC, platelets, lymphocytes, neutrophils, monocytes, eosinophils, TP, albumin, globulin, ALT, AST, ALP, creatinine, BUN, and glucose levels were examined for 6 weeks following establishment of mites. Zinc, selenium, copper, manganese, and sulfur levels were assayed at the 6th week of infestation. Hematological values of infested dogs differed significantly (P < 0.05) from healthy dogs with exceptions to monocytes and eosinophils. The eosinophil lymphocyte ratio, monocyte lymphocyte ratio, and neutrophil lymphocyte ratio of 3 weeks post infestation did not significantly differ from 6 weeks post infestation while platelet lymphocyte ratio at week 3 were elevated and significantly differed from counts at week 6. TP, albumin, and globulin values were only altered significantly (P < 0.05) from the 4th week of infestation. ALP values were affected by the 6th week following infestation while creatinine values were significantly lower in infested dogs. Zinc, copper, and selenium levels significantly decreased during infestation while manganese and sulfur amounts in study dogs showed no variations. Study established decreased zinc, copper, and selenium levels in scabies; hence, supplements with these trace elements should be incorporated to the treatment plan of mange in dogs.
Background: Scabies is one of the most common diseases in dogs. It threatens both animals and humans due to its zoonotic potential. Objective: The purpose of this study was to evaluate the oxidant/antioxidant balance with hematological findings in dogs infested with sarcoptic mange. Methods: The animals evaluated in this study consisted of 32 mixed-breed dogs between 1 and 2 years of age. The dogs were allocated into two groups: a control group (infestation-free animals; n=10), and a sarcoptic mange-infected group (Sarcoptes, n=22). Dogs in the Sarcoptes group showed infestation signs such as intense itching, excoriations, alopecia, and blistering of the elbow and auricular margins. Results: Significant increase (p<0.01) levels were observed in total oxidant status (TOS), malondialdehyde (MDA), oxidative stress index (OSI), and nitric oxide (NO), while glutathione (GSH) and total antioxidant status (TAS) levels in dogs infested with Sarcoptes decreased significantly (p<0.01). In addition, a significant increase (p<0.01) of WBC count in dogs in the sarcoptic group in comparison with the control was found. Conversely, there was significant decrease (p<0.01) in RBC, HGB, and PCV counts in Sarcoptes-infested dogs. Conclusions: Our study suggests a possible relationship between oxidant/antioxidant imbalance and hematological findings in dogs infested with sarcoptic mange. Furthermore, in addition to MDA, TAS, TOS, and OSI markers, NO as well as GSH might be also used to assess the oxidative stress in dogs naturally infected with Sarcoptes scabiei.
