A historical review of the techniques of recovery of parasites for their detection in human stools

Abstract Since the early 20th century, the detection of intestinal parasites has improved with the development of several techniques for parasitic structures recovery and identification, which differ in sensitivity, specificity, practicality, cost, and infrastructure demand. This study aims to review, in...

New approaches to studying morphological details of intramolluscan stages of Angiostrongylus vasorum

Abstract Angiostrongylus vasorum is a pulmonary artery parasite of domestic and wild canid. On molluscs, intermediate host, first stage larvae (L1) are found after the first day of infection, in the 8th L2 and in the 30 th L3. It was evaluated L1, L2 and L3 recovered by Baermann technique from Achatina f...

Geographical distribution of Leishmania species in Colombia, 1985-2017

Biomédica (Bogotá); 39 (2), 2019
Abstract Introduction: Knowledge of the geographical distribution of Leishmania species allows guiding the sampling to little-studied areas and implementing strategies to define risk zones and priority areas for control. Objective: Given that there is no publication that collects this information, the ...

Developmental stages and viability of Toxocara canis eggs outside the host

Biomédica (Bogotá); 38 (2), 2018
ABSTRACT Introduction: Toxocariasis is a soil-transmitted zoonotic disease caused mainly by ingestion of larvated eggs of Toxocara canis. Objectives: To study the morphology of the intraovular developmental stages of Toxocara canis in culture, characterize non-viable eggs and the sequences of larval m...

Visceral larva migrans. Report of a case

Rev. medica electron; 40 (2), 2018
RESUMEN La larva migrans visceral es una enfermedad que se produce al ingerir huevos infectantes de nematodos parásitos de gatos y perros (Toxocaracanis y Toxocaracati); los cuales eclosionan en el intestino del hombre y las larvas se distribuyen en todo el organismo, principalmente hígado, pulmón, co...

In vitro evaluation of ivermectin, moxidectin, albendazole and pyrantel against cyathostomins of horses

Abstract Cyathostomins are the most prevalent nematodes of horses, and multidrug resistance has been reported worldwide. There is a need to implement alternative drug monitoring analytical tests. The objective of this study was to determine the consistency (5 repetitions) of the larval migration on agar ...

In vitro efficacy of Duddingtonia flagrans against nematodes of sheep based on in vivo calculations

Abstract Duddingtonia flagrans has been tested as an alternative parasite control, but data from in vitro experiments based on in vivo calculations describing nematophagous fungi predation in nematodes are restricted. The objective of this work was to determine the efficacy of D. flagrans against sheep n...

Comparative study of three xenic media culture for cultivation of Balantidium coli strains

Abstract The aim of the present study was to evaluate the growth rate of Balantidium coli in three xenic media cultures. Between 2013 and 2015, 10 B. coli isolates obtained from feces of Cynomolgus macaques, and 30 isolates from feces of pigs were studied. An inoculum of 500 trophozoites was transferred ...

Concordance between the zinc sulphate flotation and centrifugal sedimentation methods for the diagnosis of intestinal parasites

Biomédica (Bogotá); 36 (4), 2016
Resumen Introduction: The diagnosis of intestinal parasitic infections depends on the parasite load, the specific gravity density of the parasite eggs, oocysts or cysts, and the density and viscosity of flotation or sedimentation medium where faeces are processed. Objective: To evaluate the concordance...
