“…In turn, these microbial signals are necessary for the proper development of the mucosal immune system (Honda and Littman, 2012;Hooper et al, 2012).Although it is clear that the presence of certain bacteria (Ivanov et al, 2009; Atarashi et al, 2013), viruses (Pfeiffer andVirgin, 2016), and helminths (Elliott and Weinstock, 2012) within the microbiota can impact intestinal homeostasis, the potential immune-shaping role of other kingdoms, such as Protista, has been less well studied. Protozoa are unicellular eukaryotes known to cause human diseases such as malaria, giardiasis, and trichomoniasis (Lindsay et al, 2008). In wild and laboratory mice, several protozoa have been documented to be disease causing, whereas others, such as Entamoeba muris and Tritrichomonas muris, are considered nonpatho-genic members of the murine microbiome (Baker, 2008).…”

ARTÍCULO ORIGINAL Contenido de alimento y metabolismo ceco-cólico en el tracto digestivo de poblaciones silvestres de iguana negra (Ctenosaura pectinata) en Morelos, MéxicoCecum-colic content of food and metabolism in the digestive tract of wild population black lizard (Ctenosaura pectinata) in Morelos, Mexico SUMMARYFive digestive tracts of black lizards (Ctenosaura pectinata) from a wild population were collected in Morelos State, México, in order to identify the plant composition in the diet and the cecum-colic metabolism. Smears obtained from cecum-colic content were observed to register the presence of protozoa, bacteria and intestinal parasites. The average and standard deviation were estimated from the evaluated characteristics. The plants species Guamúchil (Phitecellobium dulce) and Huizache (Acacia farnesiana) were identified in the cecum-colic content. The vegetal content of the diet was constituted by fruits (62.9%), leaves (30.6%), buds (2.9%) and flowers (3.5%), dry matter basis. The cecum-colic portion was characterised by the concentration (mmol) of acetic (68.9 ± 10.6), butyric (11.98 ± 5.7) and propionic (9.04 ± 1.5) fatty acids, total fatty acids (89.9 ± 15), pH 7.45, and ammonia nitrogen concentration (7.4 ± 2.8 mg/dl). The microbiotic observed was the Nyctotherus spp protozoa. The total bacterial count ranged from 7 x 10 8 to 9 x 10 9 /g, cellulolytic bacteria ranged from 9.2 x 10 7 to 3.5 x 10 8 /g of cecal content. The parasites observed were nematodes identified as members of the Oxyuroidea superfamily, with 655 ± 265 eggs/g and 6,300 ± 329 adults/lizard. It is concluded that the fermentation of the cecum-colon region of the adult black iguana behaves similarly to that from herbivorous species, with fermentation being carried out according to the ingested food. Dietary concentration of crude protein was 14.5% and energy 2.193 (Mcal/kg), and they are animals parasited by oxiurids.Palabras clave: Ctenosaura pectinata, parásitos, metabolismo, tracto digestivo.
