| 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 |
| hyper-variable regions in 18s rdna of strongyloides spp. as markers for species-specific diagnosis. | four hyper-variable regions (hvr-i to -iv) found in 18s ribosomal dna sequences were compared among 34 isolates of 15 species of the genus strongyloides to evaluate their diagnostic value. hvr-i to -iii were short, and plural species exhibit the same nucleotide arrangement. meanwhile, hvr-iv had 23 to 39 nucleotides, showing species-specific arrangements, except strongyloides ransomi and strongyloides venezuelensis, which had the same nucleotide sequence in hvr-iv but were readily distinguished ... | 2009 | 19050926 |
| the house fly (musca domestica) as a potential vector of metazoan parasites caught in a pig-pen in germany. | in the present study a total of 224 specimens of the synanthropic house fly (musca domestica) were caught in a pig-pen of an organic farmer in dormagen (germany). the flies were examined for their potential as a carrier of metazoan parasites. on the exoskeletons and in the intestines of the flies the eggs and/or larvae of four endoparasite nematode species of domestic pigs (ascaris suum, strongyloides ransomi, metastrongylus sp., undetermined strongylida) were isolated. also one ectoparasite spe ... | 2009 | 19081196 |
| risk factors associated with occurrence of nematodes in free range pigs in busia district, kenya. | nematode infections are a serious constraint to pig production, especially where free range pig keeping is practiced. this study investigated the epidemiology of nematodes in free range pigs in busia district, kenya. three hundred and six pigs from 135 farms were sampled for faeces that were analysed for nematode eggs per gram (epg) of faeces using the mcmaster technique. the nematode eggs were also identified to genus and species based on morphology. a questionnaire on risk factors was also adm ... | 2011 | 21833678 |
| prevalence and risk factors for gastrointestinal parasites in small-scale pig enterprises in central and eastern uganda. | in eastern africa, small-scale pig keeping has emerged as a popular activity to generate additional household income. infections of pigs with gastrointestinal helminths can limit production output, increase production costs, and pose zoonotic risks. a cross-sectional, community-based study in three districts in eastern and central uganda examined the prevalence of gastrointestinal helminthes and associated risk factors in 932 randomly sampled pigs. using the combined sedimentation-flotation meth ... | 2017 | 27785599 |
| investigations of selected pathogens among village pigs in central papua, indonesia. | village pig husbandry is an important part of livestock production in papua province, eastern indonesia. however, high level of disease and mortality constrains production. the aim of this study was to investigate the prevalence of the selected pathogens in village pigs in the jayawijaya region of papua province, indonesia. two studies were conducted: study 1 determined the prevalence of selected pathogens in dead or moribund pigs sent to the main local market for sale. study 2 recorded the prev ... | 2016 | 26381546 |
| 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 |
| microbiological, pathological and histological findings in four danish pig herds affected by a new neonatal diarrhoea syndrome. | neonatal diarrhoea is a frequent clinical condition in commercial swine herds, previously regarded to be uncomplicated to treat. however, since 2008 it seems that a new neonatal diarrhoeic syndrome unresponsive to antibiotics and common management practices has emerged. routine laboratory examinations have not detected any pathogen related to this syndrome. the primary purpose of this study was to evaluate if well-known enteric pathogens could be associated with outbreaks of neonatal diarrhoea, ... | 2013 | 24119974 |
| fluorescence in situ hybridization investigation of potentially pathogenic bacteria involved in neonatal porcine diarrhea. | neonatal diarrhea is a multifactorial condition commonly present on pig farms and leads to economic losses due to increased morbidity and mortality of piglets. immature immune system and lack of fully established microbiota at birth predispose neonatal piglets to infection with enteric pathogens. the microorganisms that for decades have been associated with enteritis and diarrhea in suckling piglets are: rotavirus a, coronavirus, enterotoxigenic escherichia coli (etec), clostridium perfringens t ... | 2014 | 24628856 |
| recovery of gastrointestinal swine parasites in anaerobic biodigester systems. | solid and liquid wastes from livestock operations represent important challenges for animal production regarding their impact in the environment and public health. parasitological tests performed on 80 samples of affluent and effluent waters from three anaerobic biodigestors with flexible structure from swine farms of caldas - colombia, showed the presence of isospora suis (45%), eimeria suis (42.5%), e. espinosa (35%), strongyloides ransomi (28.8%), e. perminuta (12.5%), e. cerdonis (3.8%), and ... | 2012 | 23070435 |
