English term or phrase: injured / stressed
Counting of bacteria by epifluorescence microscopy has become a widely used technique for direct estimation of bacteria under different physiological states (dormant, INJURED, STRESSED, viable: i.e. culturable, non-culturable or dead) using selective fluorochromes.

Cuáles son los términos exactos en este contexto? Se "estresa" una bacteria? :-)

Escucho sugerencias, gracias!

Explanation:
Patricia, I think this page will help in understanding the meaning of "stressed" pertaining to bacteria:

http://www.epa.gov/owow/tmdl/pathogen/appendixa.htm
“Stressed organisms” is the term used to refer to indicator bacteria that become injured in waters and wastewaters. These organisms are unable to grow or reproduce to form colonies under the usual culture conditions (i.e., they are viable, but nonculturable) because of structural or metabolic damage from a variety of factors, including partial or inadequate disinfection, heavy metals, ultraviolet light, and extremes of pH and temperature. False negative microbiological test results, in which some of the indicator bacteria present are not detected and standards are not exceeded, could suggest that a waterbody is safe for its designated use when, in fact, it is not. Injured organisms may retain the potential for virulence and may recover after being ingested (reviewed in APHA, 1995). A method to enhance recovery when culturing viable, but nonculturable organisms is provided in Standard Methods for the Examination of Water and Wastewater (APHA, 1995).

Mil gracias, es exactamente eso, la condición "física" de las bacterias, que permite o no generar cultivos. Les agradezco mucho a todos, y ojalá pudiera asignar puntos a más de uno. El ejemplo de Bárbara es acertadísimo, mi texto es justamente un estudio por epifluorescencia.
Gracias de nuevo!

estado activo?


Explanation:
Lamentablemente no tengo una respuesta concreta a tu pregunta pero a juzgar por los otros estados mencionados, "stressed" en este contexto puede ser "estado de actividad en respuesta a un estímulo determinado" (puede ser un cambio en la osmolaridad, etc)
Injured: lesionada

Good luck!

Bacterias dañadas o estresadas


Explanation:
Estrés osmótico en bacterias gram positivas:

EX149 Estres osmotico en bacterias gram positivas
Dir: SANCHEZ DE RIVAS, Carmen
Departamento de Química Biológica

Se ha comprobado la importancia del metabolismo del glutamato en la calidad de esporas de B.subtilis (Bs) ; mutantes auxótrofas para glutamato forman esporas de menor calidad ( OsmoR, LisozimaR)) con reducido contenido en proteinas SASP, propiedades que se revierten cuando el ámino-acido esta en exceso. Esto indica que para sintetizar estas proteinas durante la esporulación (codificadas por genes ssp ) la bacteria necesita un alto aporte de glutamato. Este ocurres normalmente por activación del ciclo de Krebs, pero en la mutante no es suficiente para contribuir a la biosíntesis de proteinas ricas en el. Por otro lado los bacilos entomopatógenos ( Bacillus thuringiensis israelensis o Bti y B.sphaericus o Bf ) forman esporas de menor calidad que han sido complementadas por transferencia de genes heterólogos (genes ssp de Bs a Bti y Bf). Estas bacterias mejoran la osmoresistencia de esporas solo cuando se introduce sspE y no sspA (codifican para SASP-E y SASP-A) cuyo destino es el citoplasma y será rapidamente proteolizada durante la germinación proveiendo a la bacteria de glutamato como osmoprotector.

El grado de superenrrollamiento del DNA interviene en la capacidad de osmorespuesta de la bacteria. La determinacón del número de linking en los distintos estadíos de crecimiento y en medios hipersalinos muestra la presencia de estas estruturas. Dósis sub-lethales de novobiocina, un inhibidor de girasa inhiben el superenrrollado y tambien la expresión de la osmoresistencia ya sea en cultivos en medios normal o aquellos adaptados a la hiperosmolaridad. En una mutante gyrB , el antibiótico no modifica el supercoiling ni la expresión de la osmoresistencia. Esto involucra la actividad girasa tanto para iniciar como para mantener la osmorespuesta.

Las muestras de agua tratada, efluente o residual puede incluir bacterias estresadas que crecen relativamente lento y producen un máximo brillo en 22-24 horas.

agree  Bertha S. Deffenbaugh: Stress is NOT necessarily related to psychological damage. Stress is anything that affects your body or mind.
