As a traditional livestock country, Uruguay is still an emergent forestry country despite the commercial plantations boom of the nineteens, based on exotic fast growing species. There is a scarce experience on the conservation, domestication and breeding of native forest species in the country and this situation has a negative impact on the establishment of agroforestry systems and on the implementation of native forests conservation and restauration actions. The purpose of this work is to present the knowledge generated in participative tree domestication of high‐value native forest species in Uruguay as a
strategy for shortening the way and opening opportunities for: (i) the improved seed and seedling production, (ii) the forest species diversification, (iii) the small scale forestry establishment, (iv) the use/incorporation of high‐value native forest trees in livestock and agriculture activities and (v) the awareness on climate change impacts and it relationship with deforestation‐afforestation, land use and land restoration. |

ABSTRACT.- Type D enterotoxemia, caused by Clostridium perfringens epsilon toxin (ETX), is one of the most economically important clostridial diseases of sheep. Acute type D enterotoxemia is characterized by well-documented lesions in the nervous, cardiocirculatory, and pulmonary systems. However, discrepancies and confusion exist as to whether renal lesions are part of the spectrum of lesions of this condition, which is controversial considering that for many decades it has been colloquially referred to as "pulpy kidney disease". Here, the authors assess renal changes in an experimental model of acute type D enterotoxemia in sheep and evaluate the possible role of ETX in their genesis. Four groups of 6 sheep each were intraduodenally inoculated with either a wild-type virulent C. perfringens type D strain, an etx knockout mutant unable to produce ETX, the etx mutant strain complemented with the wild-type etx gene that regains the ETX toxin production, or sterile culture medium (control group). All sheep were autopsied less than 24 hours after inoculation; none of them developed gross lesions in the kidneys. Ten predefined histologic renal changes were scored in each sheep. The proportion of sheep with microscopic changes and their severity scores did not differ significantly between groups. Mild intratubular medullary hemorrhage was observed in only 2 of the 12 sheep inoculated with the wild-type or etx-complemented bacterial strains, but not in the 12 sheep of the other 2 groups. The authors conclude that no specific gross or histologic renal lesions are observed in sheep with experimental acute type D enterotoxemia. © The Author(s) 2023 MenosABSTRACT.- Type D enterotoxemia, caused by Clostridium perfringens epsilon toxin (ETX), is one of the most economically important clostridial diseases of sheep.
