| characterization of staphylococcus aureus isolates from buffalo, bovine, ovine, and caprine milk samples collected in rio de janeiro state, brazil. | eighty-four staphylococcal isolates were obtained from milk samples from cows, sheep, goats, and buffalo with subclinical mastitis and from colonization samples from ostriches. the animals were hosted in 18 small dairy herds and an ostrich breeding located in 10 municipalities of the state of rio de janeiro, brazil. thirty isolates were identified as staphylococcus aureus by biochemical and molecular techniques and were comparatively characterized by phenotypic and genotypic methods. the molecul ... | 2007 | 17449696 |
| [struthiolipeurus rheae harrison, 1916 (phthiraptera: philopteridae) infesting ostriches (struthio camelus) in one farming in the municipality of três rios, rj]. | in brazil ostriches farming began at the end of 20th century, to supply the international market of meat, feathers and leather. feathers are economically important to industry and artisanal sectors. lice can cause intense pruritus that depending on the intensity of infestation can lead to depreciation of feathers. in rio de janeiro there are unknown species of lice infesting ostriches. thus the objective of this study was to identify the lice that happen in birds from commercial farms in the mun ... | 2009 | 20040199 |
| [occurrence of cryptosporidium spp. oocysts (apicomplexa, cryptosporidiidae) in ostriches, struthio camelus l., 1758 (aves, struthionidae) reared in north and lowered coastline regions of the state of rio de janeiro, brazil]. | the aim of this research was to determine the prevalence of cryptosporidium spp. in ostriches reared in the state of rio de janeiro. the diagnosis of oocysts of cryptosporidium spp. in the feces of 77 ostriches was done by modified ziehl-neelsen technique. the occurrence was observed in 44.4% of the examined animals. however, in a property 100% of the ostriches shed oocysts in their feces. oocysts was subspherical in shape with 6.33 +/- 1.27 (4.31-9.63) by 5.90 +/- 1.18 (4.07-9.42) mm and shape ... | 2008 | 20059869 |
