Materials and methods Bloodfed females of Ae. aegypti and Ae. albopictus were dissected every 4 h to determine the development status of the follicles according to the Christophers' stages. Results The minimum time of oocyte maturation in Ae. aegypti and Ae. albopictus was 64-82 h and 52-64 h post-feeding, respectively. We found that the gonotrophic cycle of Ae. aegypti (3.7-4.2 d) is longer than that of Ae. albopictus (3.2-3.7 d). The follicle length showed significant differences between species at Christophers' stages 2" and 5, whereas follicle amplitude was different between the two mosquitoes at stages 2", 3 and 4. Conclusions The study provided new evidence on the reproductive strategies of Ae. aegypti and Ae. albopictus females that coexist in the Neotropical region of Mexico.Objective To determine the presence of Rickettsia typhi in Rhipicephalus sanguineus s.l. and Amblyomma mixtum in southern Mexico. Materials and methods Ticks were collected in humans and domestic animals. The presence of Rickettsia was determined by PCR and sequencing. Results 10/39 work vials amplified fragments of the gltA, htrA and ompB genes. On 7/10 from Rh. sanguineus s.l. link2 collected from dogs and in 3/10 of A. mixtum collected from horse and human. Sequencing indicated R. typhi in Rh. sanguineus and A. mixtum with 100% homology (LS992663.1) for a region of the htrA gene and 99% (LS992663.1) with the regions of the gltA and OmpB genes. The minimum infection rate (TMI) for R. typhi was 3.88. Conclusions Rhipicephalus sanguineus s.l. and Amblyomma mixtum are naturally infected with R. typhi in Southern Mexico.Purpose To provide a summary and recommendations for the set-up of strategies for cancer patients care in genitourinary oncology clinics during the pandemic and in the recov
