ABSTRACT
The aerobic cloacal and nasal bacterial flora of 45 apparently healthy female olive ridley sea turtles (Lepidochelys olivacea )was studied at Nancite nesting beach,in Santa Rosa National Park (Costa Rican North Pacific)during July and August 2002.Bacterial samples were obtained by inserting sterile swabs directly into the cloaca and the nasal cavities of the turtles.Ninety-nine aerobic bacterial isolates, including 10 Gram-negative and 5 Gram-positive bacteria, were recovered.The most common bacteria cultured were Aeromonas spp. (13/45) and Citrobacter freundi (6/45)from cloacal samples and Bacillus spp.(32/45), Staphylococcus aureus (6/45)and Corynebacterium spp.(5/45)from nasal ducts.The results of the present study showed that the aerobic bacterial flora of nesting female olive ridleys was composed of several potential human and animal microbe pathogens.
RESUMEN
Con el objetivo de determinar la flora normal aerobia, cloacal y nasal de la tortuga lora (Lepidochelys olivacea ), entre los meses de julio y agosto del 2002,se colectaron muestras bacteriológicas de 45 quelonios aparentemente sanos,durante el desove en Playa Nancite,Parque Nacional Santa Rosa, Costa Rica, a través del uso de hisopos estériles que se introdujeron en la cloaca y en uno de los conductos nasales. De las muestras recolectadas se obtuvieron e identificaron un total de 99 aislamientos, incluyendo 10 grupos de Gram-negativos y 5 de Gram-positivos. De cada tortuga se obtuvo un promedio de 0.7 bacterias de la cloaca y 1.4 de las cavidades nasales. Las bacterias más frecuente halladas fueron Aeromonas spp.(13/45) y Citrobacter freundi (6/45) en la cloaca, y Bacillus spp. (32/45),Staphylococcus aureus (6/45)y Corynebacterium spp.(5/45)en las cavidades nasales. En este investigación, la flora microbiana de las tortugas lora resultó constituida por microorganismos potencialmente patógenos para el ser humano y las tortugas.
