Avaliação laboratorial da cinomose canina: estudo retrospectivo de 25 casos no município de Araçatuba-SP

Canine Distemper is a contagious, severe and multisystemic disease caused by a virus from Morbillivírus genus. The virus is distributed worldwide and it presents a high lethality rate, affecting mainly dogs. The diagnosis is based on clinical signs associated with hematological fi ndings. The observation of Lentz bodies in erythrocytes and leukocytes is the defi nitive diagnosis for the disease. The aim of this work was to test the hypothesis that the hematological profi le in dogs positive for canine distemper differs according to blood cell type presenting Lentz bodies. For this purpose, 25 dogs positive for the disease were evaluated at the Veterinary Hospital “Luís Quintiliano de Oliveira” UNESP, Araçatuba city. The diagnosis was based on the observation of Lentz bodies in blood smears. Fromthe total, 64% of dogs presented anemia, 16% leucopenia and 12% leukocytosis. Lymphopenia occurred in 76% of dogs. Viral inclusions were observed solely in neutrophils (32%), lymphocytes (28%) and erythrocytes (12%). Concomitant observation occurred in lymphocytes and erythrocytes (4 %), in lymphocytes and neutrophils (12%), in neutrophils and monocytes (4%) and in neutrophils and erythrocytes (4%). In an isolated case Lentz bodies were observed simultaneously in neuthrophils, monocytes and lymphocytes. In conclusion, hematological profi le is not associated with the presence of viral inclusion in a particular cell type.

Valores hematológicos de morcegos hematófagos Desmodus rotundus (E. Geoffroy, 1810) mantidos em cativeiro

Hematological values from captive vampire bats Desmodus rotundus (E. Geoffroy, 1810). Desmodus rotundus is one of the hematophagous bat species that are responsible for significant losses to livestock and has important involvement on public health. The great interest on this bat species made it becomes the target of many investigations a required its maintenance in laboratories. Similarly to others mammals, hematological evaluation has been utilized to assess the health and morbidity state of bats, however there are scarce studies with captive bats. The aim of this study was to investigate the hypothesis that is possible to feed the vampire bat D. rotundus with frozen blood treated with citrate during a long captivity period without hematological dyscrasias. Therefore, complete blood count was performed monthly from 15 adult females kept for 345 days in cages and fed with frozen blood added to citrate. The erythrocyte concentration (9.02 ± 1.43 x1012/L), PCV (0.47 ± 0.08 L/L) and hemoglobin (163.9 ± 31.5 g/L) obtained from free-living bats (immediately after capture) were lower or similar to those obtained after 345 days of captivity, presenting erythrocytes’ count of 11.01 ± 0.82 x1012/L, packed cell volume of 0.50 ± 0.05 L/L and hemoglobin level of 158 ± 10.1 g/L. The total white blood cell (11.09 ± 6.07 x109 /L) and segmented neutrophil counts (9.85 ± 3.5 x109 /L) of free living D. rotundus decreased significantly after 345 days of captivity, with values of 3.98 ± 1.98 and 1.87 ± 978.6 x109 /L respectively, which are similar to bats from temperate regions in hibernation period. This study proved that is possible to feed D. rotundus for long periods of captivity with citrated blood without the occurrence of anemia, erythrocyte or other hematologic dyscrasia

Acute phase response following ovariohysterectomy in female dogs

The concentrations of acute phase proteins are correlated with the severity of the surgical trauma, being elevated when severe tissue injury is produced. The aim of this study was to evaluate the leukogram and the acute phase proteins concentrations in healthy female dogs submitted to minimally invasive ovariohysterectomy, with the use of nylon cable ties (G1), and conventional (laparotomy) ovariohysterectomy, with the use of nylon suture (G2), as methods to ligate the ovarian pedicles and uterine body, respectively. Blood samples from 30 adult healthy female dogs (15 for each group) were obtained before surgery, and at 24 and 48 h and 7 days after surgery. Serum protein fractions were determined by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis. Neutrophilia was observed 24 h after both surgical procedures but did not differ (P ≥ 0.05) between the groups. In G1, the estimated concentration of ceruloplasmin increased (P ≤ 0.05) 48 h after the surgical procedure. The estimated ceruloplasmin concentration was significantly higher in G1 (P ≤ 0.05) when compared to G2 48 h postoperatively, and the estimated haptoglobin concentration was also significantly greater in G1 (P ≤ 0.05) than in G2 from 24 h to 7 days after surgery. Through the ceruloplasmin and haptoglobin estimated concentrations, we conclude that the minimally invasive ovariohysterectomy caused a more intense inflammatory response, which was not reflected in the white blood cell count.
