The effect of oral administration of three different nematode-trapping fungi, in aqueous suspension containing either Dactylaria sp. or Arthrobotrys oligospora conidia or Duddingtonia flagrans chlamydospores, on the number of Haemonchus contortus infective larvae in sheep faeces, was evaluated. The three selected species of fungi produce three-dimensional(More)
OBJECTIVE The Colombian National Institute of Health has been studying the epidemiology of several respiratory viruses since 1997 to identify their circulation patterns and the role they play as pathogenic agents of acute and/or moderate respiratory infection (RI) in children aged less than 5. METHODS The study used sentinel surveillance methods in(More)
OBJECTIVE A study was carried out on children seeking medical care at the Hospital Militar (Hosmil) in Bogota due to acute respiratory infection; it was aimed at estimating the frequency of respiratory virus-associated acute respiratory disease (ARD) in children aged under 10. METHODS Three to five children aged less than 10 years old were selected every(More)
Culture of human hematopoietic progenitors on a large scale could lead to several clinical applications within the near future, including the production of differentiated and functional cells, the increase in the number of early progenitors, especially stem cells, with such use as gene transfer, or the improvement of grafts used to limit the hematological(More)
Anthelmintic efficacy of ivermectin against Mecistocirrus digitatus was evaluated in 10 naturally infected zebu calves. Group 1 (n = 5) was not treated, and group 2 (n = 5) was treated SC with 200 micrograms of ivermectin/kg of body weight. Calves were euthanatized 14 or 15 days after treatment. There was 100% overall reduction of M digitatus in treated(More)
In an in vitro trial, the effect of the nematode-destroying fungus Arthrobotrys robusta on Haemonchus contortus infective larvae was evaluated in petri dishes containing corn meal agar. After seven days incubation at 25 degrees C, 92.33% (+/- 4.1) predation was recorded.
