ABSTRACT
Introduction: Leptospirosis is one of the endemic zoonoses in Cuba, causing human, animal and economic losses, making it a significant health problem. Rats are a very remarkable vector. Experimental work to study fetal renal alterations in the Wistar rats has not been carried out in Cuba.Objective: To identify the main renal morphometric alterations in fetuses of Wistar rats infected with serovar Leptospira canicola, at the Universidad de Ciencias Médicas de Pinar del Rio in the period between 2017-2019.
Method: An experimental study was carried out in pregnant Wistar rats: 2 groups with three animals each: the experimental group with a dose of bacterial concentration of 300 million leptospires per milliliter; 1 ml was inoculated to each one, infecting them with strains of Leptospira canicola. The kidneys of fetuses extracted by cesarean section were studied, and the variables: renal length and kidney weight were analyzed.
Results: The results obtained confirmed kidney damage caused by Leptospira canicola both in the major and minor axis of both kidneys, as well as variations in the weight of the infected pups.
Conclusions: Leptospiral infection in pregnant Wistar rats causes alterations in the kidneys of the fetuses, bringing changes in the morphometry of both the major and minor axes, as well as in the body weight of the fetus, which leads to a decrease in renal weight.
