Severed hemoparasitosis complicated in a thoroughbred horses from Venezuela

Abstract

Equine piroplasmosis (EP) is the disease caused by protozoan hemoparasites Babesia caballi and/or B. (Theileria equi). The aim of this study was to report of case of severed hemoparasitosis complicated in a Thoroughbred horse from Venezuela. The equine present acute abdominal pain in 24 hours and complicated post 48 hours and death in the 72 hours. Temperature oscillate 41;2°C. Icterus and hematury severed. We realized a multidisciplinary study clinical, laboratory, biochemistry, necropsy, histopathology. Hematies: 10.6 mm³, Hb: 16.4 g/dL, Hto: 48%, plaques 305mm³, Leucocites 4.7 x/mm³, Neutrophiles 47%, Lymphocytes 44%, Monocites 1%, Eosinophyles 7%. Total Protein 7,2g/dL, Albumine 2.8g/dL, globulin 4.4g/dL, glicemia 85mg/dL, urea 29mg/dL, creatinine 3.0 mg/dL. BT 3.07mg/dL, BD 0.33mg/dL, BI 2.74mg/dL, GOT 416UI/I,CK 183 UI/I, Na 136mmol/dL, K 3.0 mmol/dL, Cl 98 mmol/dL, fibrinogeno 300mg/dL. Giemsa staining of blood smears followed by careful microscopic examination can reveal the intraerythrocytic parasites in acute cases. B. caballi can appear pyriform-shaped and occurs in pairs whereas B. equi appears as four pyriform parasites in a Maltese-cross formation. On necropsy, were observed severed icterus oral and mucosa, xantomathosis of subcutaneous tissue. Poliserositis, ascitis, anasarca. In the abdominal cavity was observed massive hemoperitoneum severe, adhesive fibrinous peritonitis by diapedesis. Spleen with hemosiderosis severed. Peritonitis fibrinous adhesive in external surface of small intestine. Severe disseminate coagulate intravascular, hemolisis acute and bacteraemia, septicaemia. In conclusion were reported of case of severed hemoparasitosis complicated in a Thoroughbred horse from Venezuela.

La Piroplasmosis equina (EP) es una enfermedad causada por el protozoo hemoparásitos Babesia caballi y / o B. (Theileria equi). El objetivo de este estudio fue reportar un caso de hemoparasitosis severa complicada en un caballo Pura Sangre de Venezuela. El equino presento dolor abdominal agudo en 24 horas y 48 horas edema de miembros posteriores y muerte en las 72 horas. La temperatura oscilo entre 41, 2 º C, presento ictericia y hematuria. Se realizó un estudio multidisciplinario clínicos, de laboratorio, bioquímica, necropsia e histopatología. Hematíes: 10,6 mm ³, Hb: 16,4 g / dl, Hto: 48%, plaquetas de 305 mm ³, los Leucocitos 4,7 x / mm ³, neutrófilos 47%, linfocitos 44%, monocitos 1%, Eosinofilos 7%. Total de proteínas 7,2 g / dl, Albúmina 2.8g/dL, 4.4g/dL globulina, glicemia 85mg/dL, urea 29mg/ dL, creatinina 3,0 mg / dl. BT 3.07mg/dL, BD 0.33mg/dL, BI 2.74mg/dL, GOT 416UI / l, CK 183 UI / l, Na 136mmol/dL, K 3,0 mmol / dl, Cl 98 mmol / dL, fibrinógeno 300mg/dL. El frotis de sangre coloreado con Giemsa seguido por el examen microscópico revelo parásitos intraeritrocíticos. B. caballi puede aparecer en forma piriforme y se produce en parejas, mientras que B. equi aparece como cuatro parásitos piriformes en una formación de Cruz-Malta. En la necropsia, se observo la mucosa oral y conjuntival icterica, xantomathosis del tejido subcutáneo. Poliserositis, ascitis, anasarca. En la cavidad abdominal se observó hemoperitoneo masivo peritonitis fibrinosa severa adhesiva por diapédesis. Bazo con hemosiderosis, Coagulación intravascular diseminada, hemólisis aguda, bacteremia y septicemia. Se reporto un caso de hemoparasitosis severa complicado en un caballo pura sangre de Venezuela.
