| first report of ancylostoma ceylanicum in wild canids. | the parasitic nematode ancylostoma ceylanicum is common in dogs, cats and humans throughout asia, inhabiting the small intestine and possibly leading to iron-deficient anaemia in those infected. it has previously been discovered in domestic dogs in australia and this is the first report of a. ceylanicum in wild canids. wild dogs (dingoes and dingo hybrids) killed in council control operations (n = 26) and wild dog scats (n = 89) were collected from the wet tropics region around cairns, far north ... | 2013 | 24533332 |
| evaluation of parasitological and immunological aspects of acute infection by ancylostoma caninum and ancylostoma braziliense in mixed-breed dogs. | this study compared the course of infection by ancylostoma caninum and ancylostoma braziliense in mixed-breed dogs infected with l3 larvae. dogs infected with a. caninum eliminated more eggs than did those infected with a. braziliense. a total of 38 % of a. caninum and 44 % of a. braziliense larvae were recovered as adult worms. there were no marked clinical abnormalities in dogs with either infection. a. caninum was associated with anemia and an increased number of circulating neutrophils, wher ... | 2013 | 23494155 |
| efficacy of a single oral administration of milbemycin oxime against natural infections of ancylostoma braziliense in dogs. | the objective of this randomized, blinded, placebo controlled laboratory study was to confirm the efficacy of a single oral administration of two marketed formulations of milbemycin oxime (interceptor(®) flavor tabs(®) and sentinel(®) flavor tabs(®)) at a minimum dose of 0.5 mg/kg (0.23 mg/lb) against natural infections of ancylostoma braziliense in dogs. thirty-six hookworm infected dogs, a minimum of 10 weeks of age and of various breeds and genders were used. fecal egg counts were done on thr ... | 2013 | 23375194 |
| rapid detection and identification of human hookworm infections through high resolution melting (hrm) analysis. | hookworm infections are still endemic in low and middle income tropical countries with greater impact on the socioeconomic and public health of the bottom billion of the world's poorest people. in this study, a real-time polymerase chain reaction (pcr) coupled with high resolution melting-curve (hrm) analysis was evaluated for an accurate, rapid and sensitive tool for species identification focusing on the five human hookworm species. | 2012 | 22844538 |
| cutaneous larva migrans: a bad souvenir from the vacation. | cutaneous larva migrans (clm) is a common endemic disease in tropical and subtropical countries. this condition is caused by skin-penetrating larvae of nematodes, mainly of the hookworm ancylostoma braziliense and other nematodes of the family ancylostomidae. we report three cases of clm acquired during vacations in different regions of brazil. | 2012 | 22747935 |
| obtaining an isolate of ancylostoma braziliense from cats without the need for necropsy. | because the eggs of ancylostoma species of dogs and cats are difficult to readily distinguish morphologically, isolation of a certain species often requires the humane death of the source animal or holding an animal after treatment to obtain worms for specific identification or to harvest ex utero eggs. the objective of this study was to obtain an isolate of ancylostoma braziliense from 1-time, field-collected samples of feline feces without the need for the killing of any animals. during a coll ... | 2012 | 22394019 |
| obtaining an isolate of ancylostoma braziliense from dogs without the need for necropsy. | isolation of a specific ancylostoma species typically requires death of the source animal, or holding an animal long enough to collect feces after treatment, for worm recovery and identification. the reason for collecting worms is that the eggs are not easy to distinguish morphologically. in keeping with the 3 rs of laboratory animal research (reduction, refinement, replacement), the objective of this study was to obtain an isolate of ancylostoma braziliense from 1-time field-collected samples o ... | 2012 | 22393913 |
| prevalence of ancylostoma braziliense in cats in three northern counties of florida, united states. | a convenience sampling of fecal specimens from 40 cats in northern florida was examined for the presence of ancylostoma braziliense eggs by using centrifugal sugar flotation and polymerase chain reaction (pcr)-restriction fragment length polymorphism (rflp). of the 40 samples, 26 (65%) contained hookworm eggs. dna from 24 samples was successfully amplified using pcr; using rflp, 10 samples were identified as containing dna of a. braziliense (41.7% of the 24 samples that successfully amplified). ... | 2012 | 22393896 |
| epidemiological and genetic data supporting the transmission of ancylostoma ceylanicum among human and domestic animals. | currently, information on species-specific hookworm infection is unavailable in malaysia and is restricted worldwide due to limited application of molecular diagnostic tools. given the importance of accurate identification of hookworms, this study was conducted as part of an ongoing molecular epidemiological investigation aimed at providing the first documented data on species-specific hookworm infection, associated risk factors and the role of domestic animals as reservoirs for hookworm infecti ... | 2012 | 22347515 |
| the impact of global climate change on the spread of parasitic nematodes | climate changes may influence the frequency, intensity and geographical distribution of parasites, directly affecting their dispersive stages in the environment (eggs, larvae) and, indirectly, the larvae living mainly in invertebrate intermediate hosts. in biologically diverse nematodes climate warming contributes to the increase in the range of distribution, colonization of new hosts and modification of their development cycles. this is particularly acute in the arctic and pertains, for instanc ... | 2017 | 28432859 |
| efficacy of a novel topical combination of fipronil, (s)-methoprene, eprinomectin and praziquantel against induced infections of ancylostoma spp. nematodes of cats. | four studies were conducted to examine the efficacy of a novel topical combination of fipronil, (s)-methoprene, eprinomectin, and praziquantel (broadline(®), merial) against ancylostoma tubaeforme and ancylostoma braziliense hookworms of cats. in each study, purpose-bred cats were randomly assigned to treatment groups of 10 or 12 cats per group. in three studies the cats were inoculated with a. tubaeforme and in one study with a. braziliense. the inoculations were undertaken on a schedule which ... | 2014 | 24703073 |
| survey of helminth parasites of cats from the metropolitan area of cuiabá, mato grosso, brazil. | besides presenting zoonotic potential, helminths of cats are responsible for gastrointestinal, hepatic, and pulmonary diseases. in order to identify the helminthic fauna, prevalence, mean intensity of parasitism (mip), and mean abundance population (map), 146 cats from the metropolitan area of cuiabá, midwestern brazil, were necropsied. in 98 these animals, 12 species of helminths were identified, comprising (species, prevalence, mip, and map, respectively): nematodes (ancylostoma braziliense [5 ... | 2013 | 23856737 |
| gastro-intestinal helminths of domestic dogs in the republic of south africa. | of the gastro-intestinal helminths found in 1 063 dogs from different parts of the country, dipylidium caninum, the most prevalent cestode, occurred in 19,7% of the animals. echinococcus granulosus was present in 10 dogs, 8 of which were from urban areas, and taenia hydatigena in 69 dogs. taemia multiceps was recovered from dogs only in the cape province and the orange free state. toxocara canis was present in 81 of the necropsies carried out on 253 dogs from the pretoria municipal area, while a ... | 1979 | 575920 |
