“…In contrast with other toxicants that cause an irreversible effect on the immune system, some effects of antibiotics may be quickly reversed (Brown 1996;Walker 2000;Lu et al 2008). In addition, the developing immune system of nestling vultures may be able to recover more quickly than a fully developed immune system ( Tizard 2000;Fellah et al 2008). This suggests that immunodepression may occur shortly after antibiotic ingestion, but also that the immune system may recover quickly after antibiotic ingestion ceases.…”

“…Humoral immunocompetence is mostly cell dependent, especially in developing individuals with an intense activity of lymphocytes, which act as mediators or effectors of most of the activation and activities of humoral molecules when the immune organs and their function are still developing ( Tizard 2000;Kaiser & Staheli 2008). In this sense, macrophages, mast cells, plasma cells, natural killer cells, lymphocytes, monocytes, heterophils and even nonleucocyte cells, such as endothelial cells, possess the capacity to activate several cytokines, interferon or complement activity (Okamura et al 2004;Kaiser & Staheli 2008).…”

“…Durante el muestreo no se llegó a obtener fetos con edades gestacionales mayores de 279 días, rango de tiempo que está com-prendido en el último tercio de gestación, periodo de alto crecimiento para todo feto mamífero. En ese periodo, el timo aumentará de tamaño y seguirá su desarrollo durante la etapa neonatal (Tizard, 2013), y con ello, posiblemente, otros vasos sanguíneos emitirán ramas arteriales y ramas venosas hacia el timo. Es así el caso de las ramas arteriales que procederán de la arteria torácica interna (Getty, 1982;Gloobe, 1989…”

“…El timo es un órgano linfoide primario de gran importancia y funcional en neonatos y animales jóvenes en crecimiento, siendo el primero en formarse durante la etapa embrionaria (Carrasco et al, 2004;Dyce et al, 2012). Este órgano permite el desarrollo de la respuesta inmune, debido a que se encarga de la producción, diferenciación, maduración y liberación de linfocitos T, siendo necesario la inmigración de células madre linfoides (provenientes del saco vitelino, hígado embrionario o médula ósea) a través de las arterias y la emigración de linfocitos T maduros por las venas (Valentich y Serra, 2008;Tizard, 2013; Junqueira y Carneiro, 2015; Kierszenbaum y Tres, 2015).…”
