El ciclo de vida de C. rogercresseyi<\/em> est\u00e1 compuesto de ocho etapas de desarrollo, dos etapas plant\u00f3nicas nauplius I y II, una etapa infestiva copepodito, cuatro etapas chalimus y una etapa adulto (adulto joven y adulto maduro).<\/p>\n\n\n\n

La cantidad de tiempo que toma a un piojo desarrollarse depende en gran medida de la temperatura.

Dentro de los\nhallazgos macrosc\u00f3picos se registra baja condici\u00f3n corporal, hemorragias,\npetequias y abrasiones en la superficie del cuerpo causando inmunodepresi\u00f3n en\nel hospedador. <\/p>\n\n\n\n
