| ixodid ticks on dogs belonging to people in rural communities and villages in maputo province, mozambique. | the species composition and geographic distribution of ixodid ticks infesting domestic dogs owned by people in rural communities and villages in maputo province was established by collecting ticks from dogs at each of 27 localities spread throughout the province. ticks were collected from a total of 132 dogs, and nine species belonging to four genera were identified. one dog was infested with six species, three with five and 13 with four species. haemaphysalis elliptica followed by rhipicephalus ... | 2008 | 18788203 |
| searching for generality in the patterns of parasite abundance and distribution: ectoparasites of a south african rodent, rhabdomys pumilio. | we studied abundance and distribution of seven ectoparasite species (fleas chiastopsylla rossi and dynopsyllus ellobius, a louse polyplax arvicanthis, mites androlaelaps fahrenholzi and laelaps giganteus and two ticks haemaphysalis elliptica and hyalomma truncatum) exploiting the same populations of the rodent host rhabdomys pumilio in south africa. we considered three general patterns of abundance and distribution, namely (i) aggregated distribution of parasites amongst individual hosts; (ii) p ... | 2009 | 19168068 |
| canine babesiosis: from molecular taxonomy to control. | abstract : canine babesiosis is a clinically significant emerging vector-borne disease caused by protozoan haemoparasites. this review article considers recent literature pertaining to the taxonomic classification of babesia and theileria species affecting dogs and the geographical distribution of these parasites. the diagnosis of canine babesiosis by traditional, molecular and serological methods is reviewed, together with recent advances in our understanding of the pathophysiology of piroplasm ... | 2009 | 19426443 |
| bm86 homologues and novel ataq proteins with multiple epidermal growth factor (egf)-like domains from hard and soft ticks. | tick control on livestock relies principally on the use of acaricides but the development of acaricide resistance and concerns for environmental pollution underscore the need for alternative control methods, for instance through the use of anti-tick vaccines. two commercial vaccines based on the recombinant bm86 protein from rhipicephalus (boophilus) microplus ticks were developed. partial protection of the bm86 vaccine against other rhipicephalus (boophilus) and hyalomma tick species suggests t ... | 2010 | 20647015 |
| the efficacy of a topically applied combination of cyphenothrin and pyriproxyfen against the southern african yellow dog tick, haemaphysalis elliptica, and the cat flea, ctenocephalides felis, on dogs. | the objective of this study was to determine the therapeutic and residual efficacy of a topically applied combination of cyphenothrin (40%) and pyriproxyfen (2%) against the tick haemaphysalis elliptica and the flea ctenocephalides felis on dogs. twelve dogs were infested with 50 ticks 2 days before they were treated and with approximately 100 fleas 6 days before treatment and again 2 days before treatment and with 50 ticks and approximately 100 fleas at weekly intervals thereafter. they were ra ... | 2010 | 20649152 |
| species composition and geographic distribution of ticks infesting cattle, goats and dogs in a temperate and in a subtropical region of south-east africa. | the species and distribution of ticks infesting cattle, goats and dogs in the eastern region of the eastern cape province, south africa and maputo province, mozambique were determined from collections made from these animals at 72 localities in the former region and 30 in the latter. eleven ixodid and one argasid species were recovered in the eastern cape province and 15 ixodid species in maputo province. the most common ticks infesting cattle and goats in both provinces were amblyomma hebraeum, ... | 2009 | 21105593 |
| why is southern african canine babesiosis so virulent? an evolutionary perspective. | abstract: canine babesiosis is a common, highly virulent disease in southern africa with even pups and juveniles being severely affected. this contrasts with bovine babesiosis, for example, where host, parasite and vector co-evolved and young animals develop immunity after infection without showing clinical signs. babesia rossi, the main causative organism of canine babesiosis in sub-saharan africa, was first described from a side-striped jackal (canis adustus) in kenya. although data are meagre ... | 2011 | 21489239 |
| evidence of new pathogenic theileria species in dogs. | babesiosis, caused by tick-borne haematozoan organisms of the genus babesia, is a parasitic disease of domestic and wild mammals. canine babesidae have historically been classified as "large babesia" (babesia canis) and "small babesia" (babesia gibsoni) based on the size of their intraerythrocytic forms. recent publications, however, suggest that the diversity of piroplasm species infecting dogs might be greater than previously appreciated. sequencing and phylogenetic analysis of the ssrrna gene ... | 2010 | 21526030 |
| the namaqua rock mouse (micaelamys namaquensis) as a potential reservoir and host of arthropod vectors of diseases of medical and veterinary importance in south africa. | the role of endemic murid rodents as hosts of arthropod vectors of diseases of medical and veterinary significance is well established in the northern hemisphere. in contrast, endemic murids are comparatively understudied as vector hosts in africa, particularly in south africa. considering the great rodent diversity in south africa, many of which may occur as human commensals, this is unwarranted. | 2014 | 25127720 |
| evidence for interspecific interactions in the ectoparasite infracommunity of a wild mammal. | co-infection with multiple parasite species is commonly observed in nature and interspecific interactions are likely to occur in parasite infracommunities. such interactions may affect the distribution of parasites among hosts but also the response of infracommunities to perturbations. however, the response of infracommunities to perturbations has not been well studied experimentally for ectoparasite communities of small mammal hosts. | 2016 | 26830510 |
| a review of piroplasmid infections in wild carnivores worldwide: importance for domestic animal health and wildlife conservation. | piroplasmids are tick-borne protozoan parasites that infect blood cells (erythrocytes, lymphocytes or other leukocytes) or endothelial cells of numerous wild and domestic vertebrates worldwide. they cause severe disease in livestock, dogs, cats, wild mammals and, occasionally, in humans. piroplasmid infections are prevalent in wild carnivores worldwide although there is limited information about their clinical and epidemiological importance. there are currently nine recognized species of babesia ... | 2016 | 27724937 |
| efficacy of an imidacloprid/flumethrin collar against fleas, ticks, mites and lice on dogs. | the studies reported here were conducted to ascertain the efficacy of imidacloprid/flumethrin incorporated in a slow-release matrix collar, against infestations of dogs by fleas, ticks, mites and lice. efficacy was evaluated against the flea ctenocephalides felis felis, the ticks rhipicephalus sanguineus, ixodes ricinus, ixodes scapularis, dermacentor reticulatus and dermacentor variabilis, the mite sarcoptes scabiei and the biting louse trichodectes canis. | 2012 | 22647530 |
| occurrence of tick-transmitted pathogens in dogs in jos, plateau state, nigeria. | canine babesiosis caused by babesia rossi, transmitted by haemaphysalis elliptica in south africa, has also been reported from nigeria. although h. leachi (sensu lato) is widespread in sub-saharan africa, published literature on the occurrence of canine babesiosis is meagre. it has been postulated that the genotype of babesia rossi erythrocyte membrane antigen 1 (brema1) may be linked to virulence of the specific isolate. the primary objective of this study was to detect and characterise tick-bo ... | 2014 | 24661795 |
| a novel combination of fipronil and permethrin (frontline tri-act®/frontect®) reduces risk of transmission of babesia canis by dermacentor reticulatus and of ehrlichia canis by rhipicephalus sanguineus ticks to dogs. | the ability of frontline tri-act®/frontect®, a topical ectoparasiticide containing fipronil and permethrin for dogs, to prevent the transmission of babesia canis as well as ehrlichia canis was evaluated by infesting dogs with infected vector ticks. | 2015 | 26586365 |
| development of a pan-babesia fret-qpcr and a survey of livestock from five caribbean islands. | babesia spp. are tick-borne protozoan hemoparasites and the second most common blood-borne parasites of mammals, in particular domestic animals. we used the clustal multiple alignment program and 18s rrna gene sequences of 22 babesia species from genbank to develop a pcr that could detect a wide variety of babesia spp. in a single reaction. the pan-babesia fret-qpcr we developed reliably detected b. gibsoni, b. canis, b. vogeli, b. microti, b. bovis, and b. divergens under controlled conditions ... | 2015 | 26423577 |
| canine babesiosis in northwestern india: molecular detection and assessment of risk factors. | in the current study, a total of 214 blood samples from dogs in and around ludhiana, punjab (india), suspected for canine babesiosis were examined with conventional and molecular assays. examination of giemsa-stained peripheral thin blood smears revealed an overall prevalence of 7.47% (16/214) for canine babesiosis encompassing 0.93% (2/214) of large babesia and 6.54% (14/214) of babesia gibsoni. however, molecular diagnosis revealed 15.42% (33/214) samples positive for b. gibsoni infection as e ... | 2014 | 25013798 |
| ehrlichiosis, babesiosis, anaplasmosis and hepatozoonosis in dogs from st. kitts, west indies. | although tick-borne diseases are important causes of morbidity and mortality in dogs in tropical areas, there is little information on the agents causing these infections in the caribbean. | 2013 | 23335965 |
| molecular detection of zoonotic rickettsiae and anaplasma spp. in domestic dogs and their ectoparasites in bushbuckridge, south africa. | members of the order rickettsiales are small, obligate intracellular bacteria that are vector-borne and can cause mild to fatal diseases in humans worldwide. there is little information on the zoonotic rickettsial pathogens that may be harbored by dogs from rural localities in south africa. to characterize rickettsial pathogens infecting dogs, we screened 141 blood samples, 103 ticks, and 43 fleas collected from domestic dogs in bushbuckridge municipality, mpumalanga province of south africa, be ... | 2016 | 26974185 |
| confirmation of occurrence of <i>babesia vogeli</i> in a dog in windhoek, central namibia. | although there is evidence of high seroprevalence of antibodies to babesia spp. in dogs in central namibia, clinical babesiosis is rarely diagnosed. rhipicephalus sanguineus sensu lato, the vector of babesia vogeli, is common in namibia while haemaphysalis elliptica, the vector of the highly virulent but morphologically indistinguishable babesia rossi, has rarely been recorded, mainly in northern namibia. on the basis of vector occurrence, clinical cases of canine babesiosis in windhoek, central ... | 2016 | 27796110 |
