Resumen
Un raro caso de infección por el gusano Ancylostoma caninum causó una úlcera aftosa en el colon en Australia Occidental. Esta enfermedad zoonótica puede estar subdiagnosticada a nivel mundial, lo que requiere una mayor conciencia clínica y un estudio epidemiológico.
Área de la Ciencia:
- Parasitología Parasitología.
- Gastroenterología y Gastroenterología.
- Enfermedades zoonóticas Las enfermedades zoonóticas son enfermedades zoonóticas.
Sus antecedentes:
- El Ancylostoma caninum (A. caninum) es un nematodo intestinal canino común.
- Las infecciones humanas, aunque son raras, pueden manifestarse como ulceración aftosa y enteritis eosinofílica.
- Casos anteriores han sido reportados en todo el mundo durante el siglo pasado.
Objetivo del estudio:
- Para informar de un caso de A. caninum inducida por aftosas ulceración del colon en Australia Occidental.
- Para resumir la literatura existente sobre las infecciones intestinales humanas por A. caninum.
- Para resaltar el potencial de subdiagnóstico de esta zoonosis.
Principales métodos:
- Análisis morfológico del gusano recuperado.
- Secuenciación del ADN (subunidad mitocondrial de citocromo c oxidasa I y regiones II del espaciador del transcriptor interno ribosomal nuclear) para la confirmación de especies.
- Revisión de la literatura de las infecciones anteriores de A. caninum en humanos.
Principales resultados:
- Se detalla un caso de úlcera aftosa de colon causada por A. caninum en un macho inmunocompetente en Australia Occidental.
- Los análisis morfológicos y genéticos confirmaron la identidad del gusano como A. caninum.
- Se proporciona un resumen de 11 casos humanos previamente reportados.
Conclusiones:
- La infección intestinal por A. caninum es una zoonosis probablemente subdiagnosticada en las regiones tropicales y templadas.
- El aumento de la conciencia clínica de los anquilostomas zoonóticos en los seres humanos es crucial.
- Se necesitan más estudios epidemiológicos para determinar la verdadera prevalencia y la importancia de A. caninum en huéspedes humanos.

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
