Resumo: | The invasive capacity and persistence of this pathogen, crop and ceca in apparently healthy birds of two broiler lines raised without growth promoter antibiotics in ration and originated from eggs inoculated eggshell and in allantoidal cavity with Salmonella Enteritidis. Histological and bacteriological exams from cecal and crop were performed with one, seven, 14 and 21 days of age after hatch in broilers of fast and slow growing rate. Bacterio-logical exams were performed fecal excretion with one, eigth, 22 and 35 days. The Salmonella Enteritidis invaded and colonizated the gastrointestinal tract of the two lines tested, but the the infection reduced with age, and was more persistant in Ross broilers. The results were different for two lines. The pathogen was excreted from just one chick of ISA Label at 22 days of age and four Ross chicks until 35 days of age. In order, Salmonella was detected in 87.5% (14/16) and 38,1% (5/16) of ceca; in 81.2% (13/16) and 12.5% (2/16) of crops; in fast and slow growing rate lines, respectively. In apparent healthy organs, excepted the crop, an inflammatory process with predominance of macrophage and lymphocytes. The slow growing rate line was effective to eliminate bacteria in the organism. Key-words: Ceca, crop, fecal excretion, inflammation. |

Realizaram-se exames bacteriológicos das excretas com um, oito, 22 e 35 dias, e histológicos e bacteriológicos do inglúvio e ceco, com um, sete, quatorze e 21 dias pós-eclosão em frangos de crescimento rápido e lento. Salmonella Enteritidis invadiu e colonizou o trato gastrintestinal das duas linhagens, mas a infecção declinou com a idade, sendo mais persistente na linhagem Ross. O patógeno foi excretado de uma única ave ISA Label até 22 dias de vida e em quatro aves da linhagem Ross até 35 dias. Constatou a Salmonella em ordem de colonização, em 87,5% (14/16) e 38,1% (5/16) dos cecos; em 81,2% (13/16) e 12,5% (2/16) dos inglúvios das linhagens Ross e ISA Label, respectivamente. Nos cecos aparentemente saudáveis, evidenciou-se um processo inflamatório com predominância de macrófagos e ou linfócitos, enquanto no inglúvio não se detectaram alterações microscópicas. A linhagem de ISA Label foi mais hábil em eliminar a bactéria do seu organismo.
