Prevalence of oocysts and sporozoites (%), and the number of cases over total sample sizes (in brackets) detected in field-collected An. gambiae females that died during the 7-day hydric stress phase of the experiment and during the ensuing desiccation challenge. During the hydric stress period females were kept either with restricted access to water (16 h) or with water ad-libitum (24 h).
