The bloodstream trypomastigotes of <jats:italic>T. (N.) godfreyi<\/jats:italic> are relatively small with a mean length of 13\u00b77 \u03bcm (range: 9\u00b71\u201321\u00b78 \u03bcm) and a mean width of 1\u00b765 \u03bcm (range: 0\u00b765\u20132\u00b769 \u03bcm). There is no free flagellum and the marginal kinetoplast is subterminal to a rounded posterior end; the undulating membrane is usually conspicuous. As with other <jats:italic>Nannomonas, T. godfreyi<\/jats:italic> developed in the midgut and proboscis of <jats:italic>Glossina<\/jats:italic> and infections matured in 21\u201328 days in laboratory <jats:italic>G. m. morsitans<\/jats:italic>. In The Gambia the normal vertebrate host appears to be the warthog, <jats:italic>Phacochoerus aethiopicus<\/jats:italic>, although elsewhere other wild and domestic suids may also be implicated in the life-cycle. <jats:italic>T. godfreyi<\/jats:italic> was identified unequivocally using a 380 bp DNA probe specific for a major genomic repeat sequence; its isoenzyme profile distinguished it clearly from <jats:italic>T. simiae<\/jats:italic> and three strain groups of <jats:italic>T. congolense<\/jats:italic>: savannah, riverine-forest and kilifi.<\/jats:p>","DOI":"10.1017\/s0031182000080756","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T13:54:34Z","timestamp":1244210074000},"page":"497-509","source":"Crossref","is-referenced-by-count":43,"title":["<i>Trypanosoma (Nannomonas) godfreyi<\/i> sp. nov. from tsetse flies in The Gambia: biological and biochemical characterization"],"prefix":"10.1017","volume":"109","author":[{"given":"J.
