Fig. 3From: A scoping review on tsetse fly blood meal sources and its assay methods since 1956 to 2022Distribution of gene-specific PCR studies for mammalian host blood meals (n = 24). Most of the studies amplified only Cyt b gene 19/24 (79.2%), 2/24 (8.3%) amplified both Cyt b and COI, 2/24 (8.3%) amplified 12S rRNA gene and 1/24 (4.2%) amplified a combination of the three genesBack to article page
