Term Description

The quantitative cross/cycle threshold (Ct) value may be reported for real-time PCR-based assays. The value is defined by the number of PCR cycles required for the fluorescent signal of a given product (targeted DNA) to cross the threshold (i.e. exceed background level). In general, the lower the Ct value, the greater the amount of targeted nucleic acid and vice versa. The interpretation (e.g. positive, negative, indeterminate) is determined based on a cut-off value. The submitter's lab reports the interpretation in OBX.8 segment of HL7 messaging.

Part Descriptions

LP19869-4   African swine fever virus
African swine fever virus (ASFV) is the causative agent of African swine fever. ASFV infects domestic pigs, warthogs and bushpigs, as well as soft ticks. The virus causes a lethal haemorraghic disease in domestic pigs, some isolates can cause death of animals within as little as a week after infection. In all of the other species the virus causes no obvious disease. ASFV is endemic to Sub-Saharan Africa and exists in the wild through a cycle of infection between ticks and wild pigsbushpigswarthogs. ASFV was first described after European settlers brought pigs into areas endemic with ASFV and as such is an example of an 'emerging infection'. The virus itself is a large DNA virus with a genome containing at least 150 genes. The number of genes differs slightly between different isolates of the virus. ASFV has similarities to the other large DNA viruses e.g., poxvirus, iridovirus, mimivirus. More recently ASFV has been associated with AIDS as a possible causal agent.

LP19869-4   African swine fever virus
The lone species of the genus Asfivirus. It infects domestic and wild pigs, warthogs, and bushpigs. Disease is endemic in domestic swine in many African countries and Sardinia. Soft ticks of the genus Ornithodoros are also infected and act as vectors. Source: National Library of Medicine, MeSH 2006
