Infection with Neospora caninum in a dog is described. The predominant clinical findings were proprioception deficit, involuntary and continuous contracture of the pelvic extremity muscles. N. caninum is structurally similar to Toxoplasma gondii, but it is immunologically distinct. Therefore, infections had been misdiagnosed as toxoplasmosis. The diagnosis was confirmed by an immunofluorescence antibody test. The parasite is sensitive to clindamycin and trimethoprim/sulphonamide, however the prognosis is poor especially if the muscle contractures have occurred.

The aim of this study is to determine the incidences of Malassezia infection and flea allergy in dogs with dermatitis complaints which were brought to veterinarians for examination in Ankara and Kırıkkale provinces. Materials and Methods: The material for this study consists of 40 pet dogs of different breeds genders and ages found in Ankara and Kırıkkale provinces of Turkey. Malassezia examination was conducted by staining smear samples taken with the acetate band method with Modified Wright’s Stain method. Flea existency examination was performed by using a flea comb.Out of the 40 dogs with dermatitis which were included in this study, 6 dogs (15%) were found to have Malassezia infection, 12 dogs (30%) were found to have flea infestation and 4 dogs (10%) were found to have together.In light of the results that were found in this study, Malassezia and flea infestation hold an important place for dogs which were brought with complaints of dermatitis to veterinary clinics for examination in Ankara and Kırıkkale provinces. Clinical veterinarians must keep in mind that, there is high incidence rates of these 2 dermatitis causing agents and also remember to especially consider them in the list of differential diagnosis.

The aim of this study was to investigate the changes in some biochemical and haematological parameters due to liver damage caused by parasites in sheep infected with Dicrocoelium dendriticum. The study was conducted on 10 healthy sheep and 60 sheep infected with D. dendriticum. After the blood was taken from the sheep brought to the slaughterhouse in Van Municipality, the liver and gall bladder were examined after the slaughter, and the blood of sheep infected with D. dendriticum was brought to the laboratory and examined for some haematological and biochemical parameters.As a result of the examination, some changes were observed in the biochemical and haematological parameters. In statistical analysis: Haematologically compared with the healthy group of sheep infected with D. dentriticum; WBC, Neu, Eo and Mon values were higher than the control group's values, while RBC, Hct, Hb and MCV values were lower and no significant change was found in the Lym level. Results of biochemical parameters of sheep infected with D. dentriticum according to statistical analysis; ALT, AST and GGT values were higher than of the health group sheep, while serum TP, Alb and glucose values were found than lower.As a result; WBC, Neu, Eo, Mon, ALT, AST and GGT levels in infected sheep due to dicrocoeliasis which cause important pathological disorders in liver that have functions such as synthesis, metabolism and detoxification in the organism were found to be significantly higher compared to the same values of the healthy group. It is predicted that these parameters may be useful in determining the degree and prognosis of liver damage and will shed light on the studies to be performed in this field.
