host-feeding pattern of culex theileri (diptera: culicidae), potential vector of dirofilaria immitis in the canary islands, spain.to identify the host range of potential vectors of dirofilaria immitis leidy, the causal agent of canine dirofilariasis, we studied the bloodmeal origin of mosquitoes trapped on two of the canary islands, gran canaria and tenerife, where this disease is considered hyperendemic. on gran canaria, mosquitoes were captured using centers for disease control and prevention (cdc) traps (outdoors) and resting in a bathroom (indoors). only cdc traps were used to capture mosquitoes in tenerife. the specie ...201223270171
geo-environmental model for the prediction of potential transmission risk of dirofilaria in an area with dry climate and extensive irrigated crops. the case of spain.zoonotic filarioses caused by dirofilaria immitis and dirofilaria repens are transmitted by culicid mosquitoes. therefore dirofilaria transmission depends on climatic factors like temperature and humidity. in spite of the dry climate of most of the spanish territory, there are extensive irrigated crops areas providing moist habitats favourable for mosquito breeding. a gis model to predict the risk of dirofilaria transmission in spain, based on temperatures and rainfall data as well as in the dis ...201424456900
the impact of the climate on the epidemiology of dirofilaria immitis in the pet population of the canary islands.cardiopulmonary dirofilariosis (heartworm) is a zoonotic vector borne disease caused by dirofilaria immitis which affects domestic dogs and cats. two of the seven canary islands are historically hyperendemic areas of dirofilariosis, although no epidemiological study has ever been carried out which includes the other islands. the aim of the study was to complete the epidemiological status of cardiopulmonary dirofilariosis in the canine and feline population throughout all the canary islands. 1643 ...201626801597
influence of parasitism in dogs on their serum levels of persistent organochlorine compounds and polycyclic aromatic hydrocarbons.persistent organochlorine pollutants (pops) are toxic chemicals, which accumulate in humans and animals, as only few species have the capability of eliminating them. however, some authors have pointed to the possibility that certain species of invertebrates (i.e. nematodes) could metabolize this type of compounds. as certain species of nematodes act as parasites of vertebrates, this research was designed to explore the influence of some of the most common parasites of the dogs in their serum lev ...201627096633
the heartworm (dirofilaria immitis) seems to be able to metabolize organochlorine pesticides and polychlorinated biphenyls: a case-control study in dogs.it has been described that the co-existence of parasite infection and chemical exposure has various effects on the accumulation of persistent organochlorine pollutants (pops) in the host. certain parasites are not only able to accumulate pops but also seem to have the ability to metabolize certain compounds. we have designed a case-control study aimed to disclose the role of dirofilaria immitis in the bioavailability of pops in dogs trying to know whether these parasites store or metabolize the ...201727751690
seroprevalence of canine heartworm disease (dirofilaria immitis) on tenerife island: an epidemiological update.blood samples from 823 dogs were tested for circulating dirofilaria immitis antigen during a 1-year period (may 2002 to may 2003) on tenerife island, canary islands, spain. seroprevalence of heartworm infection was 21%. heartworm infection was similar in males and females and was more common in dogs aged >6 years. distribution of infection in varying climatic zones was not statistically different.200616821033
epidemiological survey of canine heartworm disease on the island of gran canaria (canary islands - spain) between 2000 and 2008.canine cardiopulmonary dirofilariosis caused by dirofilaria immitis is endemic on the island of gran canaria. epidemiological surveys have shown differences in the prevalence of heartworm disease in the canine population of the island between 1989 and 1998. the aim of the present study was to follow-up the prevalence of d. immitis in both the canine population as a whole and the canarian warren hound population on gran canaria between 2000 and 2008. prevalences observed were always significantly ...201020605072
the prevalence of dirofilaria immitis in gran canaria, canary islands, spain (1994-1996).blood samples from 2034 dogs were tested to detect dirofilaria immitis antigen during three consecutive years (from 1994 to 1996) in gran canaria island, canary islands, spain. the prevalence of heartworm infection was 67.02% in 1994, 58.92% in 1995 and 52.18% in 1996, with a mean prevalence of 58.89%. heartworm infection was more common in males (56.19%) than in females (43.81 %), in dogs aged between 3 and 6 years old. the distribution of the disease in the different climatic zones was studied ...19989637223
canine dirofilariosis caused by dirofilaria immitis is a risk factor for the human population on the island of gran canaria, canary islands, spain.the aim of the present study was compare the prevalence of d. immitis in dogs and seroprevalence in humans of gran canaria (canary islands, spain) taking into consideration the four isoclimatic areas of the island. a close relationship between the prevalence of dirofilaria immitis in dogs and the seroprevalence in humans, in each isoclimatic area, was observed. the highest seroprevalence of infection in both canine and human hosts were found in a strip of mid-range altitude with 25.47% and 30.4% ...201020676685
