Resumen
Los murciélagos embarazados albergan distintas comunidades microbianas intestinales y pulmonares. Este estudio revela las principales diferencias bacterianas y las posibles implicaciones para la salud en murciélagos silvestres.
Área de la Ciencia:
- Microbiología
- Ecología de la vida silvestre
- Interacciones huésped-micróbio
Sus antecedentes:
- Las comunidades microbianas de mamíferos son vitales para la salud del huésped y la homeostasis.
- La comprensión de la microbiota en mamíferos silvestres preñados es crucial para la ecología de las enfermedades.
Objetivo del estudio:
- Para caracterizar la estructura y la función de la microbiota intestinal y pulmonar en los murciélagos de nariz de hoja Pomona embarazados.
- Identificar distintas comunidades microbianas y sus roles potenciales en la fisiología y la enfermedad del huésped.
Principales métodos:
- Secuenciación de genes de ARNr V3-V4 de muestras intestinales y pulmonares de nueve murciélagos embarazados.
- Análisis bioinformáticos que incluyen anotaciones taxonómicas, índices de diversidad (alfa y beta), LEfSe y clasificación de bosques aleatorios.
- Anotación funcional de las comunidades microbianas.
Principales resultados:
- La microbiota intestinal dominada por Firmicutes y Actinobacteriota (por ejemplo, Bacillaceae, Enterobacteriaceae); la microbiota pulmonar por Proteobacteria y Bacteroidota (por ejemplo, Rhizobiaceae, Burkholderiaceae).
- Identificación de géneros oportunistas y potencialmente patógenos distintos tanto en el entorno intestinal (Bacillus, Cronobacter) como en el pulmonar (Bartonella, Mycoplasma).
- Diferencias significativas en la diversidad y composición microbiana entre los sitios intestinales y pulmonares, con información funcional sobre las actividades metabólicas y las vías de la enfermedad.
Conclusiones:
- Los murciélagos de nariz de hoja Pomona embarazadas exhiben comunidades microbianas intestinales y pulmonares específicas del sitio.
- La microbiota identificada puede influir en la inmunidad del huésped, la fisiología y la posible aparición de enfermedades zoonóticas.

01:22Introduction to the Human Microbiota
101
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

01:27The Oral Microbiota
57
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

01:29Microbiota of the Respiratory Tract
40
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

01:27Microbiota of the Stomach and Small Intestine
60
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...

01:27Microbiota of the Large Intestine
74
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

01:18Functions of the Gut Microbiota
89
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...
