Alterações patológicas do sistema genital de cutias (Dasyprocta aguti Linnaeus, 1758) fêmeas criadas em cativeiro

This paper presents seven distinct reports diseases with reproductive origins that are not yet described in females agoutis (Dasyprocta aguti Linnaeus, 1758), affecting fertility or resulted in the animals death. The nature, location and frequency of macroscopic and histological pathological changes of the organs that compose the reproductive system of female agoutis, created under conditions of captivity in the semiarid region of Brazil, are described in this article. Were evaluated by pathological examination of the reproductive tract of thirty-nine naturally dead agoutis and sent to the Veterinary Pathology Laboratory in February 2010 to May 2015. From these, it was found pathological alterations in the reproductive system of 10 (25.6%). A total of 13 abnormalities were observed, and in some animals had the coexistence of more than one alteration. Thus, the pathological changes were: endometritis (n=4, 30.8%), pyometra (n=3; 23%), retained placenta (n=2; 15.4%), fetal maceration (n=1, 7.7%), fetal mummification (n=1, 7.7%), dystocia (n=1, 7.7%) and afuncionais ovary (n=1, 7.7%).

PCR Multiplex fluorescente para detecção de bactérias em sêmen bovino

This study aimed to evaluate the threshold of detection of fluorescent multiplex PCR coupled with capillary electrophoresis for detection of infectious agents in semen samples from experimentally infected with decreasing concentrations of the bacteria Brucella abortus, Leptospira interrogans serovar pomona, Campylobacter fetus and Haemophilus somnus. Samples of bovine semen were experimentally infected with decreasing concentrations of bacteria obtained from serial dilutions in the base 10 so as to obtain samples containing a long time until 10-7 bacteria/mL from the initial concentration of Lepstospira pomona, Brucella abortus, Haemophilus somnus and Campylobacter fetus. The dilutions were made individually for each bacterium, as well as in different concentrations needed to standardize the multiplex PCR test. DNA extractions of all solutions containing sperm and bacteria analyzed in this study were performed according to protocol described by Heinemann et al. (2000). The multiplex PCR products were analyzed by electrophoresis on 8% polyacrylamide gel and capillary electrophoretic separation system for automated equipment in the analysis of DNA fragments MegaBACE. We observed amplification of fragments of 193pb, 330pb, 415pb and 400bp from the DNA of B. abortus, L. pomona, H. somnus, C. fetus respectively. The analysis by capillary electrophoresis of multiplex PCR products of DNA for simultaneous detection of the four pathogens was observed by detecting the dilution of 10-3 bacteria / mL times the initial concentration of the stock solution of each bacterium. The multiplex PCR coupled with capillary electrophoresis was first used for the direct diagnosis of four pathogenic bacteria in semen, proving to be a rapid method to detect bacteria that cause reproductive disorders.
