Molecular screening of tsetse flies and cattle reveal different Trypanosoma species including T. grayi and T. theileri in northern Cameroon

Table 6 Distribution of Trypanosoma species in Glossina species in proboscis. Total number of Trypanosoma species detected

^aPositive flies are those, in which one or more trypanosomal amplicons was detected. Therefore, the total number of positive flies is lower than the sum of Trypanosoma detected in a fly species at a given location
^bIf no identified amplicon was detected, the fly was considered to be negative, including presence of NI100
^cAmplicon of 100 bp detected and not identified. The corresponding sample was recorded as NI (non identified)
