“…The selected birds were transferred to the Laboratory of Animal Parasitology of the Instituto Biológico, São Paulo, Brazil, and were maintained in cages with water and feed free of anthelmintic medication for a seven-day period of adaptation (Yazwinski et al, 2003). Following this period, the birds were euthanized (Yazwinski et al, 2003) and necropsied, and the Mello and Campos method was adopted (Fig.…”

“…Helminthoses evaluation in poultry is part of national and international regulations (Nurelhuda et al, 1989;Yazwinski et al, 1992;2003;Silva et al, 1999;Vich Topic GL21, 2001;Tucker et al, 2007;Alam et al, 2014;Butt et al, 2014). Methodologies owing to the cestodes recovery basically consist of collecting intestinal contents and materials scraped from the small intestine mucosa, followed by helminth screening.…”

The specific diagnosis and evaluation of the intensity of avian helminth infections are essential for efficacy studies and the determination of drug doses targeted to their control. This study evaluated the Mello and Campos method, originally described for parasitological diagnosis in dogs, in the recovery of scolices from cestode parasites of poultry (Gallus domesticus ). A total of 52 naturally infected birds obtained from farms underwent parasitological necropsy using the Mello and Campos method. The method consisted of four steps: content, soaking, scraping and evaluation. The number of scolices recovered per bird ranged from 1 to 4,345, and the highest number of scolices was recovered from material derived from the soaking step. The cestodes species diagnosed were Amoebotaenia cuneata , Choanotaenia infundibulum , Hymenolepis sp., Raillietina tetragona , Raillietina echinobothrida and Raillietina cesticillus . The Mello and Campos method, originally used to test for helminths in dogs, was effective in avian cestode testing because it includes a soaking step, which enables a more efficient recovery of scolices.

a b s t r a c tIncreasing threats from anthelmintic resistant nematode populations warrant and motivate a reappraisal of chemotherapeutic strategies for nematode control in ruminant livestock and horses. The objective of this paper is to present a guideline for the evaluation of products containing two or more constituent anthelmintic actives in a single dosage form for the treatment of nematode infections in these animals. At present, regulatory policies on the approval of such products vary across jurisdictions, and this World Association for the Advancement of Veterinary Parasitology (W.A.A.V.P.) guideline should enable the harmonization of the requirements. This guideline makes clear recommendations on the minimal standards needed, but stresses that registration dossiers for combination anthelmintic products submitted for approval must conform to the standards and practices already established in existing guidelines for anthelmintics.
