Özet

Caracteristicas hemoaglutinantes, hidrof6bicas, enterotoxigenicas y resistencia a drogas de Escherichia coli aviar. Se examinaron 35 cepas de Escherichia coli obtenidas de tejidos tomados a la necropsia de aves con septicemia provenientes de la regi6n de Konya, Turquia. Las caracteristicas examinadas fueron: hemoaglutinaci6n, hidrofobicidad en la superficie celular, enterotoxigenicidad y resistencia a las drogas. La prueba de hemoaglutinaci6n fue hecha con y sin manosa en cultivos vivos utilizando eritrocitos humanos (tipo A), bovinos, aviares (de pollo) y de cobayo. Nueve patrones hemoaglutinantes fueron observados. De las 35 cepas, 62.8% fueron sensibles a la manosa, 8.6% fueron resistentes y 28.6% no hemaglutinaron. El 85.7% de las cepas fueron hidrof6bicas usando la prueba de adici6n de sal. Solo 3 cepas fueron enterotoxig&nicas en la prueba con ratones lactantes. La mayoria de las cepas fueron resistentes al cloranfenicol, tetraciclina, estreptomicina, ampicilina, eritromicina y trimetropina + sulfametoxazola, pero fueron altamente sensibles a la gentamicina y al acido nalidixico.
Y. A total of 35 Escherichia coli isolates obtained from necropsy materials of hens with septicemia in the Konya region of Turkey were examined for hemagglutination (HA), cell-surface hydrophobicity, enterotoxigenicity, and drug resistance. HA tests were performed on live cultures with human (group A), bovine, avian (chicken), and guinea pig erythrocytes with and without mannose. Nine HA patterns were observed. Of the 35 isolates, 62.8% exhibited mannose-sensitive hemagglutination (MSHA), 8.6% exhibited mannose-resistant hemagglutination (MRHA), and 28.6% did not hemagglutinate. Of the isolates, 85.7% were hydrophobic by a salt aggregation test (SAT). Only three isolates were enterotoxigenic by a suckling mouse assay. The majority of the isolates were resistant to chloramphenicol, tetracycline, streptomycin, ampicillin, erythromycin, and trimethoprim+ sulfamethoxazole but were highly sensitive to gentamicin and nalidixic acid.
