Article Synopsis
- The study evaluated two methods of cryopreserving canine ovarian tissue—vitrification and slow freezing—by examining their effectiveness and differences based on follicular type.
- Twenty-eight ovaries from 14 anoestrus bitches were used, divided into three groups for preservation (vitrification, slow freezing, and fresh control) with specific solutions and techniques applied for each.
- Results showed that slow freezing led to significantly more intact follicles and lower apoptosis rates compared to vitrification, indicating it is a more effective method for preserving viable ovarian tissue in dogs.
Direct detection of Mycoplasma hyopneumoniae through molecular tools is a growing trend for early diagnosis, highlighting the importance of knowing M. hyopneumoniae dynamics in the respiratory tract upon infection. This study focused on monitoring the infection level and its effects in different anatomic sites of the respiratory tract of experimentally infected swine in four time-points post-infection.
