UP to the present there have been no records of any infection being produced from Phlebotomus fed on cases of kala-azar, therefore the results of the following experiment may be of interest, since they show that the flagellates which develop in the midgut of sand-flies are capable of producing the infection when they enter a susceptible host. The details of the experiment are as follows:
| selected citations These citations are derived from selected sources. This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | 3 | |
| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
| influence This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | Top 10% | |
| impulse This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network. | Average |
