The medical records of 158 dogs with visceral leishmaniasis confirmed cytologically and/or serologically were reviewed. Ages of affected dogs varied from nine months to 15 years, with a male-to-female ratio of 1.3. The most common clinical manifestations of the disease were variable cutaneous lesions such as exfoliative dermatitis and skin ulcerations, chronic renal failure, peripheral lymphadenopathy or lymph node hypoplasia, masticatory muscle atrophy (i.e., chronic myositis), ocular lesions (i.e., conjunctivitis, keratoconjunctivitis sicca, blepharitis, and uveitis), and poor body condition. Ascites, nephrotic syndrome, epistaxis, polyarthritis, and ulcerative stomatitis were seen only in a small number of cases. Clinical splenomegaly was not a common finding. The clinicopathological abnormalities were nonregenerative anemia, hyperproteinemia, glomerular proteinuria, and symptomatic or asymptomatic azotemia. In this study, an indirect immunofluorescence assay's diagnostic sensitivity was found to be higher than that of lymph node aspiration cytology.
The aim of the present study was to determine the normal ranges of the most commonly used serum biochemical parameters of sheep reared under Greek breeding conditions, as well as to test for the effects of the age and reproductive status of the animals on the normal values of these parameters. In total, 200 clinically healthy Chios sheep from 10 farms were used in the experiment. For the determination of the effect of age 150 sheep were assigned in three groups. Group A consisting of 50 lambs aged 2-6 months (mean +/- SD: 4.15 +/- 1.08), group B of 50 non-pregnant ewes into lactation aged 1-3 years (mean +/- SD: 2.12 +/- 0.86) and group C of 50 non-pregnant ewes into lactation aged more than 3 years (mean +/- SD: 5.98 +/- 1.66). For evaluating the effect of reproductive status 50 pregnant ewes in dry period were used, 15-30 days before the expected day of lambing (group D), along with the 100 non-pregnant ewes into lactation of groups B and C (group E). Blood sampling was performed once, in dry ewes from December to January, and in lambs and lactating ewes from March to May. The results showed that of the 14 biochemical parameters determined in serum, six were significantly affected by the age and eight by the reproductive stage of the animals.
A 5-month-old, female, mongrel dog was admitted to the Clinic of Companion Animal Medicine, Aristotle University of Thessaloniki, Greece, with depression, anorexia, fever, peripheral lymphadenopathy, splenomegaly, oculonasal discharge, nonregenerative anemia, and mild thrombocytopenia. Cytology of Giemsa-stained buffy coat, bone marrow, and lymph node aspiration smears revealed numerous morulae in mononuclear leukocytes and in neutrophils, and Hepatozoon canis gamonts in neutrophils. The dog was seropositive to Ehrlichia canis (immunofluorescence assay [IFA]) and Hepatozoon canis (ELISA) but not to Anaplasma phagocytophilum (IFA). A nested polymerase chain reaction performed on bone marrow aspirates was positive for E canis. This method was not applied for the detection of A phagocytophilum. Treatment with doxycycline and imidocarb dipropionate resulted in both clinical and parasitologic cure. This is the first reported case of a mixed infection with E canis, H canis, and presumptive A phagocytophilum. The findings emphasize the value of cytology in offering a quick and inexpensive diagnosis in mixed tick-borne infections of dogs.
Twenty domestic shorthaired (DSH) and 20 Siamese (S) kittens were allocated into 4 breed-specific groups, of 10 kittens each, that were fed exclusively cooked sardines (F groups) or commercial feline canned food based on oily fish (C groups) for a 4-month period. Clinical signs were scored every 15 d along with body weight recording and blood sampling for the measurement of alpha-tocopherol and selenium (Se) concentrations and glutathione peroxidase (GSH-Px) activity. Subcutaneous adipose tissue samples were obtained per month to determine its fatty acid composition. Steatitis, reproduced in all 20 F-group kittens, was accompanied by systemic signs in 5 DSH and 6 S animals. The severity of the disease reached its zenith at the second week in the DSH-F-group kittens and the fourth and sixth week in the S-F-group kittens. alpha-Tocopherol plasma level was significantly lower in F groups compared to their corresponding controls, whereas the opposite was true for Se and red blood cell GSH-Px activity. In conclusion, the results of this study have shown that although the morbidity rate is not different between the two breeds, the delay of Siamese cats to develop symptomatic steatitis is presumably attributed to an inherent resistance as a result of the long-standing evolution of more efficient antioxidant mechanisms. Also, the changes in fatty acid composition of the adipose tissue lipids are associated with the progression of the age, breed, and diet and probably with the inflammatory changes of the adipose tissue.
Results suggest that clinical spirocercosis occurs more often in young-adult, large-breed dogs. Nonregenerative anemia, neutrophilic leukocytosis, hyperproteinemia, and high alkaline phosphatase activity may be useful clinicopathologic indicators of this disease.
