Pacheco's disease Pacheco's disease Pacheco's disease is an acute and often lethal infectious disease in psittacine birds. The disease is caused by a species of herpesvirus, Psittacid alphaherpesvirus 1 (PsHV-1), which consists of four genotypes. Birds which do not succumb to Pacheco's disease after infection with the virus become asymptomatic carriers that act as reservoirs of the infection. These persistently infected birds, often Macaws, Amazon parrots and some species of conures, shed the virus in feces and in respiratory and oral secretions. Outbreaks can occur when stress causes healthy birds who carry the virus to shed it. Birds generally become infected after
Contagious caprine pleuropneumonia have varying degrees of efficacy. Isolation of "M. capricolum "subsp. "capripneumoniae" from clinical samples is the only way to definitively diagnose the infection but it is not normally performed as it is time consuming and difficult. Macrolides, tetracyclines and quinolones are active against "M. capricolum" subsp." capripneumoniae". Disease incidence is reduced by good hygiene and husbandry practices. Movement restrictions and slaughtering infected animals are recommended for countries that are newly infected. Contagious caprine pleuropneumonia Contagious caprine pleuropneumonia (CCPP) is a cause of major economic losses to goat producers in Africa, Asia and the Middle East. Disease is caused by members
