Última Cross protection by heat and cold shock to lethal temperatures in Clostridium perfringens BJM García,Santos; Limón,Julio C.; Heredia,Norma L.. A heat shock pre-treatment of Clostridium perfringens provides protection against lethality from subsequent exposure to cold shock and vice versa. Heat shocked cells were more cold tolerant (one log reduction in 65 min) than control cells (one log reduction in 34 min). On the other hand, cold-shocked cells were more thermotolerant (D55= 17 min) than the control (D55= 6.5 min). The addition of chloramphenicol (an inhibitor of protein synthesis) in the experiments indicates that synthesis of new proteins was necessary for cross protection between both treatments.

The present work evaluated several aspects of the generalized stress response [endocrine (cortisol), metabolic (glucose), hematologic (hematocrit and hemoglobin) and cellular (HSP70)] in the Amazonian warm-water fish matrinxã (Brycon amazonicus ) subjected to an acute cold shock. This species farming has been done in South America, and growth and feed conversion rates have been interesting. However, in subtropical areas of Brazil, where the water temperature can rapidly change, high rates of matrinxã mortality have been associated with abrupt decrease in the water temperature. Thus, we subjected matrinxã to a sudden cold shock by transferring the fish directly to tanks in which the water temperature was 10ºC below the initial conditions (cold shock from...
