| ascarid nematodes in domestic and wild terrestrial mammals. | the biology of the ascarid nematodes has been discussed in the context of their important economic role in farm animals, pet animals and zoo animals with special attention to carnivores and primates. in farm animals, infection with the most common roundworm of horses (parascaris equorum) and swine (ascaris suum) depend on many factors such as environmental conditions (larval development in the egg and egg survival), age of the host, breed, husbandry system, hygiene and treatment schedule. the mo ... | 2002 | 12512563 |
| molecular evidence for the infection of zoo chimpanzees by pig ascaris. | we here describe the transmission of the pig roundworm, ascaris suum to chimpanzees maintained in the copenhagen zoo, denmark. using a technique for whole genome fingerprinting, amplified fragment length polymorphism (aflp) and the technique pcr restricted fragment length polymorphism (pcr-rflp) of the internal transcribed spacer region (its) of the nuclear ribosomal dna, the worms from the chimpanzees were compared with ascaris spp obtained from humans and pigs in order to identify the source o ... | 2006 | 16567044 |
| molecular evidence for sustained transmission of zoonotic ascaris suum among zoo chimpanzees (pan troglodytes). | chimpanzees in the copenhagen zoo frequently excrete ascarid worms onto the cage floor in spite of a regular anthelmintic treatment program. previously it had been shown that the source of the infections was of pig origin. however, it was unknown whether the recurrence of the infection was due to reintroduction of eggs from an external source or to a sustained transmission cycle within the zoo. we found that isolated eggs were able to embryonate to the infective j3 stage and pcr-rflp analysis on ... | 2010 | 20400228 |
| complete mitochondrial genomes of chimpanzee- and gibbon-derived ascaris isolated from a zoological garden in southwest china. | roundworms (ascaridida: nematoda), one of the most common soil-transmitted helminths (sths), can cause ascariasis in various hosts worldwide, ranging from wild to domestic animals and humans. despite the veterinary and health importance of the ascaridida species, little or no attention has been paid to roundworms infecting wild animals including non-human primates due to the current taxon sampling and survey bias in this order. importantly, there has been considerable controversy over the years ... | 2013 | 24358225 |
