Figure 4. (A) B. burgdorferi sensu lato infection prevalence per site in 2024, (B) overall prevalence of B. burgdorferi s.l. (Bbsl) species in 2024. Bbss: Borrelia burgdorferi sensu stricto. 1,7,8: alluvial forests; 2,3: city parks with connectivity to a forest; 4,5,6: city parks and botanical garden.
Figure 1 Field collection sites for ticks at Étang de Bolmon using flagging (A), dry ice placed on the ground to attract ticks (B), and direct visual searches by collectors (C). (D, E) Male Hyalomma lusitanicum ticks on the ground. See supplementary videos illustrating tick collection at: https://doi.org/10.5281/zenodo.20141476.
Figure 3. Representative images of Hyalomma lusitanicum (A, female dorsal view; B, female ventral view; C, male dorsal view; D, male ventral view) and Rhipicephalus pusillus (E, female dorsal view; F, female ventral view; G, male dorsal view; H, male ventral view) specimens collected in this study conducted at Étang de Bolmon, Southern France. Bar scale: 1 mm.

Figure 1. Large trypomastigote of Trypanosoma sp. found in Streak-eared bulbuls (Pycnonotus conradi). Morphotype SEBL-I showed large trypomastigotes with purple cytoplasm and distinct scattered azurophilic granules (A), morphotype SEBL-II showed large trypomastigotes with purple cytoplasm without distinct scattered azurophilic granules (B), morphotype SEBL-III showed large trypomastigotes with deep purple cytoplasm and scattered pale spots (C), and morphotype SEBL-IV showed large trypomastigotes with deep purple cytoplasm, scattered pale spots and pale/colorless at both ends (D). Note: Free flagellum = black arrow, longitudinal striations (myonemes) = white arrow, pale spots = black arrow head, azurophilic granules = white arrow head.
Dactylosoma cf. ranarum SK in blood smears of Pelophylax esculentus. A) Trophozoite. B–G) Primary merogony: B) Early meront. C; D) Young primary meront released from host cell, presumably due to cell damage or lysis. The meront in C appears to be partially protruding into the lymphocyte, suggesting a possible interaction. E; F) Primary meront with 12 budding merozoites. G) Primary merozoites. The top inset shows one of the merozoites that has already invaded the nearest erythrocyte; the bottom inset shows another primary merozoite from a different smear preparation. H–L) Secondary merogony: H; I) Young secondary meront. J) Maturing secondary meront with eight nuclei. K) Secondary meronts with eight budding merozoites. L) Secondary merozoites. M) Immature gamonts at various stages of development and a secondary merozoite. N) Immature gamont released from degraded erythrocyte. O) Mature intracellular gamont. P) Mature extracellular gamonts. Bright-field microscopy, Giemsa staining. Scale bar applies to all micrographs. Black arrowhead – condensed chromatin/nucleus, black asterisk – merozoite following erythrocyte invasion, de – degrading erythrocyte, ly – lymphocyte, white arrowhead – apical end of gamont.
