Filarioids of the genus Cercopithifilaria are little studied, yet widespread parasites, that are relatively unique in being one of the very few nematodes transmitted by hard ticks. These filarioids live in the subcutis while microfilariae are found in the dermis. Definitive hosts include domestic dogs as well as a wide range of vertebrates, such as ruminants, non-human primates, murids, marsupials, porcupines, viverrids, bears and lagomorphs. The genus Cercopithifilaria contains three taxa (i.e. C. bainae, C. grassii and a yet undescribed species, namely Cercopithifilaria sp. II) that are known to infect dogs worldwide, with their occurrence overlapping the distribution of the main tick vector, Rhipicephalus sanguineus sensu lato. In recent decades, more attention has focused on these filarioids since they have been associated with clinical signs of infection, such as dermatitis, chronic polyarthritis and cutaneous cysts, and possibly with facilitating infections caused by other tick-borne pathogens. Nevertheless, these parasites remain largely underdiagnosed in clinical practice due to the lack of awareness of veterinary practitioners and to major obstacles to their diagnosis. In this review, we have assessed currently available data on Cercopithifilaria spp. infecting dogs worldwide and discussed the biological, clinical and epidemiological aspects of these filarioids, with the overall aim to gain a better understanding of their potential role in skin diseases.

“…Ticks (Acari: Ixodida) are obligate hematophagous ectoparasites capable of transmitting multiple pathogens such as bacteria, helminths, protozoa, and viruses (de la Fuente et al 2008;Baneth 2014;Bezerra-Santos et al 2022). Ixodida comprises three families: Argasidae (soft ticks), Ixodidae (hard vectors of Rickettsia parkeri s.s.

The tick species that comprise the Amblyomma maculatum group (Acari: Ixodidae) are widely distributed in the Nearctic and Neotropical regions, ranging from the United States of America (USA) to Argentina. This group includes three species: Amblyomma maculatum, Amblyomma tigrinum, and Amblyomma triste, which parasitize a high number of vertebrates, including domestic mammals and humans, where they are the main vectors of Rickettsia parkeri s.s. The identification, distribution, and validity of the three species within the group have been controversial and continue to raise questions. Previous studies have mostly focused on the analysis of partial nuclear and mitochondrial genes, highlighting the need for new integrative analyses that contribute to clarifying their systematics and ecology. In this investigation, we obtained the first mitochondrial genome of A. triste (14,808 bp), which, upon comparison with the reported mitochondrial genomes of A. maculatum, exhibits a genetic distance of 4.2%, providing new evidence for the validity of the former species. The order, composition, and structure of the mitogenome of A. triste are consistent with the characteristics reported for most Metastriata including taxa within Amblyomma, that count with several mitochondrial genomes published in the last few years. The attributes of the mitogenomes, such as the absence of paralogs and a small genome, confirm the utility in studies involving complexes of cryptic species as it also serves as a robust tool for inferring phylogenies. Furthermore, we reported new molecular markers at the mitochondrial level which can be used in phylogenetic studies for other tick species, especially those with controversial or challenging taxonomy. We highlight the need of sequencing the mitochondrial genome of A. tigrinum, which is part of the A. maculatum group, as well as experimental crosses of populations from different places in the Americas to obtain additional evidence for species recognition.

“…Ticks (Acari: Ixodida) are vectors of a wide variety of tick-borne pathogens (TBPs) causing several tick-borne diseases (TBD) in humans and other vertebrates worldwide ( Sonenshine and Roe, 2014 ; Gondard et al, 2017 ; Maqbool et al, 2022 ). The family Ixodidae includes ticks recognized as vectors of bacteria, helminths, protozoa, and viruses that can cause different conditions in humans (e.g., human anaplasmosis, Lyme borreliosis, and tick-borne encephalitis), in domestic animals (e.g., babesiosis and ehrlichiosis), and in wildlife (e.g., rickettsiosis) ( Baneth, 2014 ; Efstratiou et al, 2021 ; Michalski et al, 2021 ; Bezerra-Santos et al, 2022 ; Velásquez-Guarín et al, 2024 ). In addition to pathogens, the set of microbial biotas associated with the tick is defined as the "microbiome" and includes other commensal and endosymbiotic microorganisms that ticks harbor and can be vertically inherited ( Greay et al, 2018 ; Wu-Chuang et al, 2021 ; Grandi et al, 2023 ).…”
