Abstract: The aim of the present study was to evaluate the anthelmintic efficacy of three commercial compounds against ascarids and Capillaria spp. in naturally infected fighting cocks from Mexico. First experiment.- Forty cocks were selected on the basis of eggs per gram (EPG) counts quantified by the McMaster method. On day 0 the birds were divided into four groups of 10 cocks, each subjected to the treatments. Group 1 received a single oral dose of 1 mg of ivermectin, 25 mg of praziquantel and 40 mg of fenbendazole given in tablets according to body weight (b.w). Group 2 was treated with a single oral dose of 1 mg of ivermectin, 25 mg of praziquantel and 40 mg of fenbendazole given in tablets/b.w. but formulated with a different excipient. Group 3 received a single tablet containing 0.2 mg of abamectin and 30 mg of albendazole. Group 4 served as a non-treated control. Fecal analyses were carried out on days 0 (day of treatment), 7, 14, 21 and 28, being collected from the floor where the cocks were individually caged. Efficacy was measured on the percentage of egg reduction from day 0 with respect the EPG counts from the control group. In a second experiment the study was similarly performed using another cock-farm located at approximately 300 km away from the first one. Results indicated an overall efficacy of 100%, 94.0% and 100% for groups 1, 2 and 3 in the first experiment and 100%, 100%, 100% for groups 1, 2 and 3 of the 2nd experiment, respectively. It is concluded that all drugs used exerted high efficacy in fighting cocks naturally infected with helminths.

International Journal For Pharmaceutical Research Scholars , 2013,
Abstract: Ziziphus oenoplia Linn., Mill, is a commonly occurring thorny shrub found to have many uses such as anthelmintic, antiseptic, hepatoprotective, stomachalgia, digestive etc. It is also used in ascaris infection and healing of wounds. The plant is reported to possess alkaloids, tannins and carbohydrates. Alkaloids have also been reported to posses many biological activities like anticancer, hepatoprotective, antihelmintic etc. Therefore, this plant offers much scope to investigators on different perspectives such as Pharmacognosy, Phytochemistry and Pharmacology. The following studies highlight the botanical as well as phytochemical constituents, macroscopic, microscopic and preliminary studies of roots. These observations will help in the botanical identification and the standardization of drug in crude form and also to distinguish the drug from its adulterants. Hopefully, this little work will help to inform the people who are not aware of the plant Ziziphus oenoplia Linn., mill (Rhamnaceae) which has multi-farious beneficial properties for medicine, agriculture and husbandry.

Abstract: In Danish horses resistance to benzimidazole products in the Cyathostominea spp. has been reported twice [2,3] and resistance to pyrantel is suspected [3]. Anthelmintic resistance (AR) is regarded as an increasing problem worldwide, but the factors that contribute to the development of AR are often speculative. Epi-demiological techniques have enhanced the ability to study the complex interactions between factors that may contribute to the occurrence of AR. High frequency of treatment [15], repeated use of anthelmintics with the same mode of actions [7], the generation intervals of the parasites [4] are factors which have been associated with the risk of development of AR in production animals. A low efficiency of a drug might be an indication that AR has developed. Some parasites survive treatment, what facilitates selection of AR parasites [13]. This makes it necessary to investigate the association between AR and management strategies, which potentially could contribute to its development. Factors previously identified in other production animals are also expected to be important for the development of AR in the horses, but as horses often are handled as a companion animal other factors might contribute to the development of AR.The objective of this study was 1) to identify risk factors associated with high endoparasite burden and 2) to evaluate the efficiency of a single anthelmintic treatment of Danish horses.In 1994 veterinarians from "The Danish Horse Practising Veterinarian Society" were contacted, and 22 veterinarians entered the survey and selected large (>15 horses) horse herds among their clients. In 1995 a questionnaire was sent to the selected herd owners. Sixty-eight herd owners answered the questionnaire, and 56 of the selected herds with a total of 903 horses entered a Faecal Egg Count Reduction (FECR) test [3].In 1997 the herd owners were interviewed with the aim of validating the questionnaire [10].Initially bivariate analyses were performed, and

Abstract: A thoroughgoing study on resistance was achieved for the first time in insecticides, later on finding that, this can be extended also in anthelmintic substances. The resistance to anthelmintics evolved gradually from a simple medical curiosity, to an important economic problem. Many factors contribute to the appearance of resistance to anthelmintic substances. After epidemiological studies on various helmintic populations, it was concluded that there are four essential and distinguish factors that induce the appearance of parasitic resistance: operational factors, genetic factors, biological and ecological factors. In the last two decades there were conceived many tests to give emphasis to the phenomenon of resistance, but very few were accepted and validated at an international level. The motivation for this phenomenon consist in the fact that every of this methods have a certain sensibility, feasibility and profitableness. All these tests have positive aspects, and few negative aspects, that make themhard to be utilized (apparatus and high costs) or there are not enough sensible, so the obtained results are difficult to be interpreted. The use of molecular technique for the diagnosis of resistance to anthelmintics does not represent a viable option in the present, because the data about the intimate molecular mechanisms of resistance to anthelmintics are very few and there are not confirmed by the clinical reality.
