Interactions within the tick microbiome involving symbionts, commensals, and tick-borne pathogens (TBPs) play a pivotal role in disease ecology. This study explored temporal changes in the microbiome of , an important cattle tick vector, focusing on its interaction with . To overcome limitations inherent in sampling methods relying on questing ticks, which may not consistently reflect pathogen presence due to variations in exposure to infected hosts in nature, our study focused on ticks fed on chronically infected cattle.

Article Synopsis
  • Dirofilarioses are diseases caused by mosquito-borne nematodes, notably Dirofilaria immitis, which primarily affects dogs in America; past studies in Cuba relied on non-specific methods for identification.* -
  • This study provided a molecular characterization of nematodes from a dog in Cuba, confirming they were D. immitis using specific gene analysis, with sequences matching those from other animals and mosquito vectors.* -
  • Further research is needed to understand the spread of canine dirofilariosis in Cuba and to identify which mosquito species are effective vectors for these parasites.*

Tick-borne pathogens (TBPs) pose a significant threat to livestock, including bovine species. This study aimed to investigate TBPs in cattle and ticks across four sampling points, utilizing real-time microfluidic PCR. The results revealed that ticks were found infesting all animals.

Article Synopsis
  • Haemotrophic mycoplasmas are unique, wall-less bacteria that infect dogs and can cause infectious anemia, particularly in those with weakened immune systems.
  • A study in Cuba tested 391 dog blood samples and found a 17.9% positivity rate for these bacteria, with 'Mycoplasma haemocanis' being the most common.
  • Key risk factors for infection included tick infestations and living in kennels, but no link was found between these infections and anemia; this research provided the first molecular evidence of these infections in Cuban dogs.

The present study aimed to determine the prevalence of zoonotic vector-borne pathogens, including , , sensu lato, and spp. in shelter dogs from Cuba. Blood samples were collected from 100 shelter dogs and examined by molecular methods.

Canine hepatozoonosis caused by Hepatozoon canis is a worldwide distributed tick-borne disease of domestic and wild canids that is transmitted by ingestion of Rhipicephalus sanguineus sensu lato (s.l.) ticks.

Ticks and the vast array of pathogens they transmit, including bacteria, viruses, protozoa, and helminths, constitute a growing burden for human and animal health worldwide. In Cuba, the major tropical island in the Caribbean, ticks are an important cause of vector-borne diseases affecting livestock production, pet animal health and, to a lesser extent, human health. The higher number of tick species in the country belong to the Argasidae family and, probably less known, is the presence of an autochthonous tick species in the island, .
