Epididimite ovina por Actinobacillus seminis no Estado de Pernambuco

This study reports the occurrence of sheep epididymitis and the isolation of Actinobacillus seminis in the state of Pernambuco, Brazil. An increase in volume of the testicles and epididymis, pain and increase in the local temperature at palpation, and bilateral testicular atrophy were clinically observed. After slaughter, the presence of purulent content in the epididymis was found. In microscopy of the testicles, coagulation necrosis and calcification of seminiferous tubules, thickening of the tunica albuginea, fibrosis, inflammatory infiltrate with predominance of lymphocytes between seminiferous tubules and incipient mineralization of tubules was observed. In the epididymis, intense proliferation of conjunctive tissue and fibrosis around the epididymal ducts was found. The diagnosis of epididymitis by Actinobacillus seminis was confirmed with association of the clinical findings, isolation and identification of the bacteria, as well as through histopathological exam.

Detecção de Toxoplasma gondii em órgãos do sistema reprodutivo de carneiros naturalmente infectados no Brasil

The aim of the study was to detect genomic DNA of Toxoplasma gondii in testicle and epididymis samples from rams sold in abattoirs in the state of Pernambuco, Northeast Brazil. Fifty (50) blood serum samples were collected, as well as 50 testicle and epididymis samples. Indirect Immunofluorescence (IIF) was used during screening of the rams. The Polymerase Chain Reaction (PCR) was used with animals that were positive in serology. Our results confirmed that 24% (12/50) of the rams were positive in IIF. Genomic DNA was detected in the epididymis at 8.3% (1/12) of the animals. The molecular identity of the amplified products was confirmed through sequencing. This paper reports the first occurrence of T. gondii DNA in the reproductive organs of naturally infected rams in Brazil.

Occurrence of Toxoplasma gondii DNA in sheep naturally infected and slaughtered in abattoirs in Pernambuco, Brazil

The aim of the present study was to assess the occurrence of antibodies to Toxoplasma gondii and to detect genomic DNA of the parasite in the reproductive organs, fetuses and fetal membranes of sheep in slaughterhouses in the state of Pernambuco, Brazil. The Indirect Immunofluorescence technique (IFA) was used for screening. The Polymerase Chain Reaction (PCR) was used to detect DNA of T. gondii in the animals that were positive in the serology. In the serology, 13/50 samples were positive and genomic DNA of T. gondii was detected in one uterus, tube, ovary, placenta and fetus (heart, brain and umbilical cord) sample from a sheep that was positive in the serology. The present study provides evidence of the occurrence of T. gondii DNA in the organs of the reproductive system, placenta and fetus of a naturally infected sheep.
