Morphological evidence of gregarines (Phylum: Apicomplexa) in Triatoma dimidiata, Chagas disease vector in Mexico: Rediscovering Machadoella triatomae and a new intestinal gregarine.

The objective of this study was to morphologically characterize the structures suggestive of gregarines found in the feces of Triatoma dimidiata collected in five municipalities in Yucatan, Mexico. Three hundred ninety-six specimens of T. dimidiata collected during 2022 and 2023 were analyzed, of which 8.

Entomo-virological surveillance of Flavivirus in mosquitoes in Yucatan State, Mexico.

The genus Flavivirus (Family: Flaviviridae) comprises arboviruses with the capacity to infect humans and animals. It also integrates insect-specific viruses. This study aimed to identify Flavivirus in mosquitoes captured in 17 municipalities in Yucatan State, Mexico.

Dataset of assembly and annotation of the mitogenomes of and captured from Yucatán, México.

is a species complex, and its members are responsible for the transmission of , the causative agent of Chagas disease. We present the assembly and annotation of the mitogenome of the (Latreille, 1811) and Lima-Cordón & Justi, 2019. The mitochondrial genomes were successfully sequenced using the Illumina Nextseq 500 platform, 2×75 cycles, and 5 million reads per sample.

Congenital Transmission of in Naturally Infected Dogs.

Congenital transmission (CT) of in dogs has not been clearly demonstrated, even though dogs are important reservoirs of this agent. Seventeen late pregnant dogs seropositive for were selected, and a total of 84 fetuses were obtained. Blood and heart tissues from the fetuses and dams, and placental tissue from dam were collected.

Mites associated with budgerigars (Psittaciformes: Psittacidae) and the first report of (Mesostigmata: Macronyssidae) in Mexico.

Background: Hematophagous mites affect numerous bird species, causing severe injuries to the budgerigars. Some species can cause dermatitis in humans.

Aims: The purpose was to morphologically identify the mites related to budgerigars ( and their nests in Yucatan, Mexico.
