| prevalence of common gastrointestinal nematode parasites in scavenging pigs of different ages and sexes in eastern centre province, burkina faso. | the range and infestation intensities of gastrointestinal parasitic nematode species depend on the type of swine production system. the present study focused mainly on nematodes of veterinary importance in scavenging pigs in burkina faso, and aimed at determining the prevalence of gastro-intestinal nematode parasites by means of faecal egg per gram (epg) counts. between november 2001 and october 2002, faecal samples from 383 pigs of different sexes and ages (< 5 months, 5-12 months and > 12 mont ... | 2006 | 16715878 |
| the prevalence of gastrointestinal helminth infections in pigs in kenya. | the prevalence of helminth infection, species spectrum and worm burdens in kenyan pigs was examined. a total of 115 gastrointestinal tracts (git) from 61 growers and 54 adult pigs were examined between february 2005 and january 2006. seventy eight (67.8%) had one or more helminth parasites, of which thirty six (31.3%) were mixed infection. ten types of helminth parasites encountered in descending order of prevalence were, oesophagostomum dentatum (39.1%), trichuris suis (32.2%), ascaris suum (28 ... | 2008 | 18509940 |
| prevalence of gastrointestinal nematodes in growing pigs in kabale district in uganda. | during the last 30 years, pig production in uganda and neighbouring counties has increased markedly. pigs are mainly kept as a source of income for small-scale farmers; however, the pig production is subject to several constraints, one of them being worm infections. a study was carried out in rural communities in kabale district in the south western part of uganda in september and october 2007 in order to estimate the prevalence of gastrointestinal nematode parasites in pigs based on coprologica ... | 2010 | 21088893 |
| helminth infections of wild boars ( sus scrofa) in the bursa province of turkey. | the present study aimed to investigate the status of helminth infections in wild boars in the bursa province of turkey. for this purpose, during 2007-2008, 27 wild boars were necropsied and examined for helminths. individual samples of tongue and diaphragm from 27 necropsied wild boars and an additional 22 tongue and diaphragm samples provided by hunters were examined by trichinoscopy and artificial digestion for trichinella spp. larvae. twenty animals (74%) were identified as being infected wit ... | 2010 | 21114894 |
| anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 µg/kg/day), against nematodes in naturally infected pigs. | the present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the epg (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. the animals were randomly selected based on the average of three consecutive epg counts of strongylida, ascaris suum and trichuris for experiment i, and of strongylida and trichuris for experiment ii. after the ... | 2014 | 25278142 |
| gastrointestinal helminths of wild hogs and their potential livestock and public health significance in jamaica. | an investigation into the potential for transmission of gastrointestinal helminths from wild hogs to livestock and humans was prompted by concerns of recreational wild-hog hunting in the caribbean region and the recent practice, by livestock farmers in jamaica, of co-rearing wild and domesticated swine. thirty-one wild hogs from the hellshire hills, a dry limestone forest in southern jamaica, were necropsied during the period june 2004 to august 2006. thirteen of the captured animals were male a ... | 2016 | 26821705 |
