Arginine decarboxylase activity in the cattle tick Rhipicephalus microplus suggests an alternative polyamine biosynthetic pathway.
The cattle tick Rhipicephalus microplus may rely on an alternative polyamine biosynthesis pathway mediated by arginine decarboxylase activity. This hematophagous ectoparasite is a major constraint to livestock production in tropical and subtropical regions, and its control is increasingly compromised by the rapid emerg...
