Congelação de espermatozoides epididimários de gatos utilizando o diluidor Botu-crio® após refrigeração por 24 h em contêiner de transporte de sêmen Botu-tainer®

The possibilities of using the sperm collected from the epididymis have been widely used because the fertilizing capacity sperm preservation and the possibility of using it for wild cats. But in the process of cryopreservation, some studies show a decrease in the quality of the sperm when left under cooling before frozen for some time. This study aimed to assess the quality of the epididymal sperm obtained from domestic cats after cryopreservation using a diluent based on egg yolk and glycerol (Botu-crio®), comparing the morphofunctional characteristics after cooling for 24 hours in a container of semen transport (Botu-tainer®). We use eight cats submitted to elective orchiectomy, aging from eight months, without racial determination, and good nutritional status. These sperm characteristics were: motility, vigor, concentration, membrane integrity and morphology. It has been found, after statistical analysis, that the container of semen was able to maintain sperm viability, even for 24h. We also observed a significant decrease on all parameters after frozen, consequential, probably to thermal stress that occurs in processing. However, the percentage of membrane integrity after thawing shows good employability of the Botu-crio®, which viability is possible to perform in vitro fertilization, requiring higher ratings.

Síndromes oculares secundárias a infecção pelo Herpesvirus felino-1-Revisão

The feline infectious respiratory disease is the most common diagnosed infection in the veterinary clinic routine, being the Feline Herpesvirus1 the most important causal agent. Once infected, the cat will become a lifetime latent carrier, experiencing episodes of viral reactivation and spontaneous spread especially when there is a stress factor involved. This virus acts in the upper respiratory system and is also associated with eye diseases. The diagnosis is made by viral isolation and treatment protocol is based on a topic antiviral therapy, even though many of them are epiteliotoxic and may progress with intense discomfort in felines.The purpose of this paper is to describe the main ocular manifestations and syndromes seen in cats suffering from feline herpesvirus. Conjunctivitis, epithelial and stromal keratitis, corneal ulceration and indolent ulcers are the main ocular manifestations associated with viral infection, whereas symblepharon, keratoconjunctivitis sicca, proliferative keratitis and corneal sequestration are the main eye syndromes that can be observed in infected animals.

High incidence of 'Dag-like' sperm defect in the domestic cat

The occurrence of a high incidence of sperm tail defects in a male domestic cat resembling the known 'Dag-like' defect is reported. Sperm analyses were performed in ejaculated samples collected by an artificial vagina and in testicular and epididymal sperm cells after castration. The following alterations were observed using transmission electron microscope: heavily coiled sperm tails containing several axonemal units enclosed in the same common cell membrane; aberrations in the axonemal main structure; and swollen and unevenly distributed mitochondria in the midpiece. Abnormal modifications in the mitochondrial sheath were also found in sperm cells retrieved from testes and epididymides. Considering these findings, we can conclude that this is the Dag-like defect, described previously in other domestic species and a testicular origin may be involved. © ISFM and AAFP 2012.

Validation of the English version of the UNESP-Botucatu multidimensional composite pain scale for assessing postoperative pain in cats

Background: A scale validated in one language is not automatically valid in another language or culture. The purpose of this study was to validate the English version of the UNESP-Botucatu multidimensional composite pain scale (MCPS) to assess postoperative pain in cats. The English version was developed using translation, back-translation, and review by individuals with expertise in feline pain management. In sequence, validity and reliability tests were performed.Results: Of the three domains identified by factor analysis, the internal consistency was excellent for 'pain expression' and 'psychomotor change' (0.86 and 0.87) but not for 'physiological variables' (0.28). Relevant changes in pain scores at clinically distinct time points (e.g., post-surgery, post-analgesic therapy), confirmed the construct validity and responsiveness (Wilcoxon test, p < 0.001). Favorable correlation with the IVAS scores (p < 0.001) and moderate to very good agreement between blinded observers and 'gold standard' evaluations, supported criterion validity. The cut-off point for rescue analgesia was > 7 (range 0-30 points) with 96.5% sensitivity and 99.5% specificity.Conclusions: The English version of the UNESP-Botucatu-MCPS is a valid, reliable and responsive instrument for assessing acute pain in cats undergoing ovariohysterectomy, when used by anesthesiologists or anesthesia technicians. The cut-off point for rescue analgesia provides an additional tool for guiding analgesic therapy. © 2013 Brondani et al.; licensee BioMed Central Ltd.

Bilateral extraluminal ectopic ureters in a Maine Coon cat

Ectopic ureters are rarely observed in cats. Therefore, for a better chance of success in the corrective surgical procedure and survival of the patient, diagnosis should be confirmed early. This report illustrates the occurrence of bilateral ectopic ureters in a seven month old Maine Coon cat and describes the medical and surgical management adopted for correction of the abnormality.

Prevalence of Toxoplasma gondii and Leishmania spp. infection in cats from Brazil

A total of 386 feline blood samples from Brazil were collected and analyzed by the indirect immunofluorescence antibody test (IFAT) for the presence of Toxoplasma gondii and Leishmania spp. antibodies. Specific antitoxoplasma IgG were found in 63 of 386 (16.3%) cats and immunoglobulin G against Leishmania spp. was detected in two serum samples. The overall prevalence was significantly higher in adult cats than in juvenile cats for T. gondii infection. There were no significant differences between positivity and gender or breed. The frequency of T. gondii antibodies found in domestic cats of Brazil suggests active transmission within an urban environment. This study proved the occurrence of two important protozoan zoonosis in felines from Brazilian endemic area for visceral leishmaniasis. © 2013.

Glaucoma secundário em cães e gatos

Glaucoma is a syndrome that affects animals of different species and in different moments of his life, having variables causes in function of this presentation. It is an ophthalmic emergency that may develop irreversible vision damage as well as the patient's aesthetic presentation. Increased intraocular pressure, presence of engorged episcleral vessels, conjunctival hyperemia, pain, anterior uveitis, lens luxation and buftalmia are commonly clinical signs presented by dogs while in cats, signs are less expressive, noting mydriasis, mild ciliary injection and progressive buftalmia. For diagnosis are carried out three basic procedures: tonometry, gonioscopy and ophthalmoscopy. The treatment can establish with medical therapy with or without surgical intervention, however, at some point it will be necessary to perform enucleation or evisceration of the eye bulb.
