prevalence of coccidia in pigs in zimbabwe.faecal specimens from 162 piglets, aged 1-5 months, from four farms around harare were examined for coccidia during 1989-1990. oocyst count per gram (opg) of faeces was determined by the mcmaster technique. identification of eimeria species was done after sporulation of oocysts in 2.5% potassium dichromate solution. measurements of sporulated oocysts were taken from 20 positive cases by using calibrated eye micrometer. overall incidence was 25.3% (41/162) varying between 15 and 39.5% at differen ...19921561754
concurrent infection of enterocytes with eimeria scabra and other enteropathogens in swine.bacteria were detected in the enterocytes of the distal jejunum in weaned pigs on days 7 and 9 post-infection (dpi) with eimeria scabra in addition to the developmental stages of the coccidia. short rod-shaped bacteria were identified in approximately 60% of the enterocytes that contained developmental stages of e. scabra. no such bacteria were observed in cells where coccidia were absent. gamonts of cryptosporidia were also observed within the microvillous zone of the enterocytes in the distal ...19902343533
pathology and pathogenicity of eimeria scabra (henry, 1931) in experimentally infected pigs.pathology and pathogenicity of the coccidium eimeria scabra were studied in pigs experimentally infected at 1-2 months of age. two phases were evident in the course of pathogenic process. in the first phase, 7-8 days after inoculation (dai), caudal jejunum and ileum were affected by a severe catarrhal inflammation characterized by intensive infiltrate containing numerous neutrophils and eosinophils, vigorous activation of peyer's patches, villous fusion and general atrophy of epithelium. in the ...19873428760
preliminary communication on cryptosporidiosis of pigs in viet-nam.feces were collected from 17 pigs (aged 4-8 weeks) in several farms situated within the region of hanoi. by coproscopy of the samples, eggs of ascaris suum and oesophagostomum dentatum were detected as well as oocysts of eimeria scabra, e. debliecki, e. perminuta and e. suis, and in addition to it, cryptosporidia to an extend indicating a considerable incidence of this parasitic protozoan in the country.19863804081
coccidosis caused by eimeria scabra in a finishing hog.coccidiosis caused by eimeria scabra was diagnosed in a 60-kg finishing hog with severe diarrhea and weight loss. fresh and fixed tissues from a farrowing to finishing operation in eastern georgia were submitted. examination of hematoxylin-eosin-stained sections of small intestine revealed large numbers of thick-walled oocysts and large macrogamonts. although coccidiosis has been associated with diarrhea in baby pigs, coccidiosis as a cause of diarrhea in finishing swine is seldom reported.19853997655

differentiation of porcine eimeria spp. by morphologic algorithms.oocysts of eimeria spp. were isolated from feces of naturally infected sows by conventional flotation. saturated sodium chloride solution was superior to zinc chloride, zinc chloride/sodium chloride or sugar solution to isolate oocysts. seven species, namely eimeria scabra, e. polita, e. perminuta, e. debliecki, e. suis, e. porci and e. spinosa, were identified. the dimensions of oocysts (n = 4088) and sporocysts (n = 3594) were measured with an image analysis system; colour and shape of oocysts ...199910190864
interactive classification of porcine eimeria spp. by computer-assisted image analysis.digitalized pictures of oocysts of eimeria scabra, e. polita, e. debliecki, e. suis, and e. porci were used to develop a program routine that allows semi-automatic interactive classification of porcine eimeria spp. with a computer-assisted image analysis system. morphological parameters (shape, color, length and width of oocysts and length and width of sporocysts) were assayed, transformed to color and shape factors and used to calculate classification indices (g1, sp). thresholds were defined f ...199910496694
pcr-based differentiation of three porcine eimeria species and isospora suis.isospora suis and eimeria are frequent coccidian parasites of pigs. the unsporulated oocysts of eimeria species and of i. suis are difficult to differentiate. therefore, a species-specific pcr was developed. pcr products were amplified from eimeria polita, eimeria porci, and eimeria scabra using primers from the conserved 18s rrna regions and were subsequently sequenced. based on variable sequence regions, primers were constructed for the differentiation of the three eimeria species and i. suis. ...200111163694
prevalence of coccidian infection in suckling piglets in china.to determine the prevalence of coccidian infection in suckling piglets in china, fecal samples from 779 litters of suckling piglets were collected on 80 different farms in 17 provinces from september 2009 to december 2010. these samples were examined through saturated saline flotation technique. the prevalences of coccidian infection ranged from 0 to 32.5% among different provinces and the average was 16.7% (130/779). the highest prevalence of 19.9% (69/346) was found in 8-14 day-old litters of ...201222694832
