Vibrio damsela, una bacteria marina, causa úlceras en la piel de las damiselas Chromis punctipinnis
Resumen
Una nueva bacteria marina, Vibrio damsela, causa úlceras cutáneas en las damiselas. Este patógeno, que se encuentra en el agua y en las heridas humanas, también puede causar enfermedades humanas.
Área de la Ciencia:
- Microbiología marina microbiología marina.
- Patología de los peces Patología de los peces
Sus antecedentes:
- Se observaron úlceras cutáneas de origen natural en la damisela herrera (Chromis punctipinnis).
- Una nueva bacteria marina fue aislada de estas úlceras.
Objetivo del estudio:
- Para identificar y caracterizar la nueva bacteria marina.
- Para determinar la patogenicidad de la bacteria en damiselas y otras especies de peces.
- Para investigar la presencia de la bacteria en el medio ambiente y su potencial como patógeno humano.
Principales métodos:
- Aislamiento e identificación de la bacteria marina.
- Estudios de laboratorio de infección utilizando damiselas y otras especies de peces.
- Aislamiento bacteriano de muestras de agua y heridas humanas.
Principales resultados:
- Una bacteria marina no descrita previamente, Vibrio damsela, fue aislada con éxito.
- Vibrio damsela produjo úlceras similares a las observadas de forma natural al infectar experimentalmente a la damisela herrero.
- La bacteria fue patógena para cuatro especies adicionales de damiselas, pero no para peces de otras familias.
- Vibrio damsela también se aisló del agua y de dos casos de heridas humanas.
Conclusiones:
- Vibrio damsela es una bacteria marina recientemente identificada responsable de las úlceras cutáneas en las damiselas.
- La bacteria exhibe especificidad del huésped, afectando principalmente a las damiselas.
- El aislamiento ambiental y la presencia en heridas humanas sugieren que Vibrio damsela puede representar un riesgo para la enfermedad humana.

Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Bacterial Phylum Proteobacteria
Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...
Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Bacterial Phylum Verrucomicrobiota
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...
