Abstract

Bovine leukaemia virus (BLV) is associated with enzootic bovine leukosis (EBL). BLV causes malignant lymphoma and lymphosarcoma; however, most BLV infections remain clinically silent in an aleukaemic state. EBL is a notifiable disease, and official control measures include screening or monitoring, precautions at borders, control of movement inside the country, and stamping out. The objective of this study was to evaluate EBL eradication and surveillance measures in Italy from 2005 to 2012. One-hundred twenty-three outbreaks were recorded (1 January 2006 to 31 December 2012) in the National Veterinary Information System (SIMAN) on 7 November 2013. Of these, 101 had occurred in southern Italy. An outbreak usually lasted for a few days, but sometimes lasted for weeks. Some areas were subjected to normal eradication measures, whereas others were subjected to additional eradication measures as a consequence of persisting EBL outbreaks. During the study period, we noted an overall annual decrease from 0.21% in 2005 to 0.08% in 2012 in the herd prevalence rate, from 0.06% in 2005 to 0.04% in 2012 in the herd incidence rate, and from 0.027% in 2005 to 0.015% in 2012 in the animal prevalence rate. Regions officially recognised as EBL-fr...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
