| uncinaria sanguinis sp. n. (nematoda: ancylostomatidae) from the endangered australian sea lion, neophoca cinerea (carnivora: otariidae). | this study investigates the identity of hookworms parasitising the australian sea lion, neophoca cinerea (péron), from three colonies in south australia, australia. the australian sea lion is at risk of extinction because its population is small and genetically fragmented. using morphological and molecular techniques, we describe a single novel species, uncinaria sanguinis sp. n. (nematoda: ancylostomatidae). the new species is most similar to hookworms also parasitic in otariid hosts, uncinaria ... | 2014 | 25065131 |
| ivermectin treatment of free-ranging endangered australian sea lion (neophoca cinerea) pups: effect on hookworm and lice infection status, haematological parameters, growth, and survival. | a placebo-controlled study was used to investigate the effectiveness of ivermectin to treat hookworm (uncinaria sanguinis) and lice (antarctophthirus microchir) infections in free-ranging australian sea lion (neophoca cinerea) pups and to test the hypotheses that these parasitic infections cause anaemia, systemic inflammatory responses, and reduced growth, and contribute towards decreased pup survival. ivermectin was identified as an effective and safe anthelmintic in this species. pups administ ... | 2015 | 25911163 |
| health assessment of free-ranging endangered australian sea lion (neophoca cinerea) pups: effect of haematophagous parasites on haematological parameters. | evaluation of the health status of free-ranging populations is important for understanding the impact of disease on individuals and on population demography and viability. in this study, haematological reference intervals were developed for free-ranging endangered australian sea lion (neophoca cinerea) pups within the context of endemic hookworm (uncinaria sanguinis) infection and the effects of pathogen, host, and environment factors on the variability of haematological parameters were investig ... | 2015 | 25724096 |
| unexpected absence of genetic separation of a highly diverse population of hookworms from geographically isolated hosts. | the high natal site fidelity of endangered australian sea lions (neophoca cinerea) along the southern australian coast suggests that their maternally transmitted parasitic species, such as hookworms, will have restricted potential for dispersal. if this is the case, we would expect to find a hookworm haplotype structure corresponding to that of the host mtdna haplotype structure; that is, restricted among geographically separated colonies. in this study, we used a fragment of the cytochrome c ox ... | 2014 | 25262830 |
| epidemiology of hookworm (uncinaria sanguinis) infection in free-ranging australian sea lion (neophoca cinerea) pups. | understanding the fundamental factors influencing the epidemiology of wildlife disease is essential to determining the impact of disease on individual health and population dynamics. the host-pathogen-environment relationship of the endangered australian sea lion (neophoca cinerea) and the parasitic hookworm, uncinaria sanguinis, was investigated in neonatal pups during summer and winter breeding seasons at two biogeographically disparate colonies in south australia. the endemic occurrence of ho ... | 2014 | 25056940 |
| analysis of codon usage pattern of mitochondrial protein-coding genes in different hookworms. | the phenomenon of unequal usage of synonymous codons encoding an amino acid in which some codons are more preferred to others is the codon usage bias (cub) and it is species specific. analysis of cub helps in understanding evolution at molecular level and acquires significance in mrna translation, design of transgenes and new gene discovery. in our current study, we analyzed synonymous codon usage pattern and the factors influencing it on mitochondrial protein coding genes of 6 different hookwor ... | 2018 | 29157661 |
