ABSTRACT

The occurrence of canine externa otitis in Fortaleza-Ceará is reported. About 91.5 percent of the animals with clinical signs were positive to bacterial culture. Among all infections, 49.5 percent were mixed infections and the most common pathogens were Staphylococcus spp coagulase negative or positive and Pseudomonas aeruginosa. The most effective antimicrobials for Staphylococcus coagulase negative were: the quinolones, the aminoglicoside netilmycin and the beta-lactams, excepted ampicillin, penicillin and oxacilin; for Staphylococcus coagulase positive were: cefotoxin, amoxicillin + clavulanic acid, imipenem, netilmycin and cephatoxin; for Pseudomonas aeruginosa were: ciprofloxacin, tobramycin and imipenem.

ABSTRACT

The hematological and serum proteins electrophoretic profiles of 13 dogs with distemper (Lentz inclusion body in leukocytes) were studied. The most frequent hematological findings were: normocitic normocromic anemia (61%), leukopenia (46%), left shount (54%), trombocytopenia (69%) and lymphopenia (85%). Electrophoretic analysis of serum proteins showed hypoproteinemia (54%), with reduced albumin and increased alfa-2 globulin. These findings can be used to support the clinical diagnosis of canine distemper.

ABSTRACT

Cryopreservation extends the availability of sperm for fertilization; however, the fertilizing potential of the frozen-thawed sperm is compromised because of alterations in the structure and physiology of the sperm cell. These alterations, characteristics of sperm capacitation, are present in the motile population and decrease sperm life-span, ability to interact with female tract, and fertilizing ability. The etiology of such alterations may represent a combination of factors, such as inherited fragility of the sperm cell to withstand the cryopreservation process and the semen dilution. Although the former is difficult to address, approaches that make-up for the dilution of seminal fluid may be sought. The aim of this work is to review aspects of sperm cryopreservation paralleled by events of capacitation and evaluate the possible roles of sperm membrane cholesterol, reactive oxygen species, and seminal plasma as mediators of cryopreservation effects on sperm function.
