Avaliação dos dados obtidos em um programa de esterilização cirúrgica de gatos em Araçatuba, SP no período de 1996 a 2010

Cats are gradually occupying a more important position as pets and this preference is a result of how easy cat maintenance in an urban environment is, even though they are very prolific and need surgical sterilization. This paper aims at evaluating obtained data within 15 years of research in a university service program that offers free cats sterilization surgery. We carried out a statistical analysis of data shown in the records of animals treated by the program. Surgical sterilization was performed on 647 animals (409 females – 63% and 238 males – 37%). Unilateral cryptorchidism was observed in 9 (3.8%) male cats. Forty (10%) female cats were pregnant at the time of the surgery and the treatment with contraceptives was observed in 67 (16.4%) female cats. One death occurred during anesthesia recovery and 2 cats were euthanized because of wound infection, totalizing an amount of 0.5% of severe complications. From 1996 to 2004, 212 female cats were spayed (122 adults and 90 prepubertal) and during that time two different approaches for ovariohysterectomy were compared: flank laparotomy and ventral midline celiotomy. The flank laparotomy approach was used in only 46 female cats (21.7%) due to some disadvantages observed – the need of an incision on each flank in prepubertal or nulliparous animals and the difficulty or impossibility of total uterus removal. In the same period, 105 male cats underwent orchiectomy via an open technique in which the spermatic cord was linked with nylon thread. From 2005 to 2010, 197 females (106 adults and 91 prepubertal) were spayed. The minilaparotomy technique was used to perform ovariohysterectomy on 139 female cats (70.6%). In this procedure, ovaries and uterus were exteriorized in a blind fashion with a hook through a small midline incision. The traditional midline ovariohysterectomy, which incision length permits direct visualization of the ovaries and uterus, had to be performed in 58 (29.4%) female cats due to advanced pregnancy, full urinary bladder during surgery or obesity. Over the past 6 years, 133 male cats (48 adults and 85 prepubertal) were castrated by means of an open technique in which the spermatic cord was tied to itself. The demand for surgeries during the project demonstrated that people are becoming aware concerning the importance of sterilization when facing cat overpopulation and abandonment.

Leishmania sp. amastigotes identification in canine transmissible venereal tumor

Leishmaniasis is a vector-borne disease with Leishmania chagasi being the etiological agent of canine visceral leishmaniasis in South America. Canine venereal tumor is a transplantable round cell tumor of histiocytic origin which is mostly observed in sexually active male and female intact dogs. It has been shown that Leishmania amastigotes have higher tropism for the canine male genital tract tissues and venereal leishmaniasis transmission has been documented in dogs but, to date, a canine venereal tumor-dependent transmission route has not been fully demonstrated. In this report, a 10-year-old, mixed breed, intact female dog presented a vaginal venereal transmissible tumor but no other clinical abnormalities otherwise. Unexpectedly, tumor tissue imprint smears examination revealed Leishmania sp. amastigotes within infiltrating macrophages. In addition to the cytological direct identification, the protozoan was confirmed within the neoplastic tissue by means of immunohistochemistry and polymerase chain reaction. This report illustrates an asymptomatic Leishmania sp. infection that may have started on or from the canine venereal tumor tissue, the latter option further supporting previous evidence of such an alternative vector-independent route of transmission for canine visceral leishmaniasis in areas where these diseases coexist.

Reproductive physiology, and physical and sexual development of female offspring born to diabetic dams

Objectives: The objective of this study was to evaluate physical and sexual development and reproductive physiology in female rat offspring that developed in hyperglycemia conditions in utero and during lactation. Materials and methods: Maternal diabetes was induced in female rats by a single IV injection of streptozotocin before mating. Female offspring development was evaluated by means of the following parameters: physical development; age of vaginal opening and first estrus; weight and histological evaluation of uterus and ovaries; duration of the estrous cycle, sexual behavior, and fertility after natural mating. Results: In the female offspring, maternal diabetes caused delays in initial physical development; diminution in ovary weight and number of follicles; and inferior reproductive performance compared with the control group. Conclusions: The exposure to hyperglycemia in uterus and during lactation caused delays in physical and sexual development, and affected the reproductive physiology of female rats negatively.

Biopsias luteais em vacas Nelore

The present study describes a technique to obtain consecutive luteal samples by colpotomy. The animals received an epidural anesthesia and local anesthesia (vaginal vault) and after ten minutes the vaginal vault was incised with a scalpel blade and tissue was dissected to provide access to the pelvic cavity and to retract the ovary into the vagina. Then, a luteal biopsy was performed with a Yomann biopsy nipper. Signs indicative of pain and stress during the vaginal vault incision, traction of ovary or luteal biopsy were observed only in two collections. However, these signs were observed in ten collections during dissection of the vaginal wall and peritoneum. The occurrence of ataxia was observed in 26 collections and it was usually related to a longer duration of the procedure. Ataxia could be divided in light (15/26), moderate (6/26) and severe (5/26). The occurrence of ovarian adhesions ipsilateral to the incision was evaluated only in the initial four collections. Adhesions were present in 16 collections. The protocol described above provided a safe and efficient method to acquire luteal samples. The low incidence of adhesions allows the consecutive use of females without any interference in subsequent ovulations and collections.
