Analyses of environmental correlates of the composition of gastrointestinal parasite communities in black howler monkeys (Alouatta pigra) have been hindered by inadequate calibration techniques of detection and quantification methods of the parasites.Here we calibrate samples and compare the likelihood of parasite detection using two flotation techniques, …

Modified flotation method, an effective technique for …

Originally, our flotation method was developed to separate only Toxocara eggs from sandpits, but later studies [4], [5], [6], using further modified flotation methods, revealed that these methods could also be used to recover other soil-transmitted helminth eggs. The present one is a unique tool to assess soil contamination effectively and will ...

JCDR

The present study found that 64.5% of the cases were detected by the formol-ether method, thus making it the most sensitive method. The inclusion of the modified formol-ether and the simple salt flotation techniques in the routine practice increases the sensitivity of the parasite detection.
