The present study was carried out to assess the capacity of Morada Nova (MON) and Santa Inês (SIN) hair sheep breeds to maintain homeothermy and its relation with semen quality in a tropical climate. Sixteen rams (MON=7 and SIN=9) were assessed for 12 months. During summer and spring, the Temperature-Humidity Index values surpassed the level indicative of thermal stress, and sweating, respiratory and heart rates increased (P < .05). Those responses allowed animals to dissipate heat, maintain rectal temperature in the physiological range and efficiently avoid thermal stress. Scrotal temperatures rose during summer and spring, but, unlike what occurs in wool breeds of sheep, the thermal gradient between poles of testis increased, which shows efficient compensatory scrotal thermoregulation in both breeds herein studied. Semen quality parameters remained within normal ranges. The high correlation observed between rectal and spermatic funicle temperature gradients with sperm membrane integrity (r=0.62; P < .05) confirmed the importance of systemic and gonadal thermoregulation for the production of ejaculates with highest possible proportion of viable spermatozoa. Thus, MON and SIN rams can be considered resilient to tropical climate since they efficiently perform the thermolysis to face thermal challenges with no negative impact on semen quality throughout the year. Those adaptability characteristics are highly desirable in the genotypes proposed for use in production systems in tropical environments.

The role of Escherichia coli in healthy microbiota of psittacine is controversial, and the presence of Salmonella sp. indicates possible disease. Therefore, this study aimed to identify the presence of E. coli and Salmonella spp. in a psittacine pet that died in Fortaleza, Brazil, correlating pathogenicity aspects of the isolates through the evaluation of lesions and antimicrobial susceptibility. Psittacine pets sent to the Laboratory of Ornithological Studies, State University of Ceará, that died in 2014 and 2015 were necropsied. Fragments of liver, kidneys, intestine, lung, heart, spleen and brain were collected for microbiological and histopathological analyses. Scores were attributed to lesions and isolated strains submitted to antimicrobial susceptibility test. From the seventy necropsied birds, nineteen were positive for E. coli and one for Salmonella Typhimurium. Congestive lesions and lymphoplasmocitic inflammatory infiltrate were observed varying from light to moderate and were the main findings. In the analyzed strains, multidrug resistance against different groups of antibiotics was observed. In conclusion, according to the results, E. coli strains and the Salmonella Typhimurium isolate produced significant lesions in the psittacine pets, and multidrug resistance may hinder treatments with antibiotics used in avian pet medicine. |
