A 12-day-old, 14.4-kg, female foal of Australian Miniature Pony breed was presented at the National Chung Hsing University Veterinary Medicine Teaching Hospital, Taiwan, with a history of weakness of 2 days’ duration. The mare died of unknown cause on the previous day. Abnormal findings during physical examination included an estimated dehydration of 3 to 5%, dark red oral mucous membranes, elevated heart and respiratory rates, stiffened feces, and absence of intestinal motility on auscultation. Continual nursing care was followed by intravenous fluid therapy and nonsteroidal anti-inflammatory drug and antibiotic treatment. The foal's condition deteriorated rapidly, and feeding was refused. Subsequently, she developed signs of pyrexia and panting. In spite of oxygen supplement, she died 18 hours after admission. Postmortem examination revealed the presence of a jejunojejunal intussusception, 20 cm in length; a torsion of jejunum proximal to the intussusception also was noted. An ulcerative lesion, 3 cm in diameter, was found on the mucosa of duodenum. Large amounts of sand, coat hair, and hay mantling in bloody discharge were observed in a colonic impaction. That it was an acute case was evident by the involvement of intussusception and ulceration, indicating desquamation of the necrotic epithelial cells with edema and distinct infiltration of neutrophils. These results suggested that a practical management strategy for nursing an orphan foal should be performed to avoid a similar case in the future. 相似文献

A novel virus, tilapia lake virus (TiLV), has been identified as a key pathogen responsible for disease outbreak and mass mortality of farmed tilapia. We used a deterministic susceptible‐infectious‐mortality (SIM) model to derive key disease information appraised with published TiLV‐induced cumulative mortality data. The relationship between tilapia mortality and TiLV exposure dosages was described by the Hill model. Furthermore, a disease control model was proposed to determine the status of controlled TiLV infection using a parsimonious control reproduction number (RC)‐control line criterion. Results showed that the key disease determinants of transmission rate and basic reproduction number (R0) could be derived. The median R0 estimate was 2.59 in a cohabitation setting with 2.6 × 105 TCID50 fish?1 TiLV. The present RC‐control model can be employed to determine whether TiLV containment is feasible in an outbreak farm by quantifying the current level of transmission. The SIM model can then be applied to predict what additional control is required to manage RC < 1. We offer valuable tools for aquaculture engineers and public health scientists the mechanistic‐based assessment that allows a more rigorous evaluation of different control strategies to reduce waterborne diseases in aquaculture farming systems. 相似文献
