The aim of this study was to evaluate the excessive duration of the study program and the academic situation of the entrants of the Professional School of Veterinary Medicine (EPMV) of the Universidad Nacional Mayor de San Marcos. The study followed up on entrants between 2004 and 2013, whether or not they had completed their studies. The formal graduation time was established at seven years (formal excess duration index = 1.0) and the time for timely graduation at eight years (timely excess time index = 1.0). By 2022, 78% of entrants had completed their studies, 21% had dropped out, and 42% had a professional degree. The average time from entry to obtaining the professional degree was 10.1 years. The formal excess duration rate was 1.45, so graduates needed 45% more time (about 3 years) to achieve their degree, while the timely excess duration rate was only 1.27. In conclusion, there is...

The aim of this retrospective study was to determine the frequency of tumors in the reproductive organs of female canines and felines, based on histopathological records of the Animal Pathology Laboratory of the National University of San Marcos (period 2007- 2015), and to correlate breed, age and anatomical site with the histopathological diagnosis. The frequency of neoplasia in the canine reproductive organs was 5.99 ± 1.16% IC95% and in feline was 4.41 ± 4.88%. In bitches, tumors were most often found in pure breeds (60.22 ± 9.95%), between 8 to 12 years (43.75 ± 9.92%) and mostly in the vulvar area (37.50 ± 9.68). The most common tumor in the ovary was the tumor of granulosa cells (47.6 ± 21.4%), while in uterus was leiomyoma (50.0 ± 40.0%) and in the vulva and vagina was the transmissible venereal tumor (39.4 ± 16.7%). In cats two dysgerminomas in ovaries and one polypoid fi...

El objetivo del presente estudio retrospectivo fue determinar la frecuencia de neoplasias del aparato reproductivo de caninos y felinos hembras según los registros histopatológicos del Laboratorio de Patología Animal de la Universidad Nacional Mayor de San Marcos (periodo 2007-2015), evaluando datos sobre raza, edad, localización anatómica y diagnóstico histopatológico. La frecuencia de neoplasias del aparato reproductor de hembras caninos fue de 5.99 ± 1.16% IC95% (96/1603) y para felinos fue de 4.41 ± 4.88% IC95% (3/68). En caninos, la mayor frecuencia se presentó en razas puras (60.22 ± 9.95%), en canes entre 8 a 12 años (43.75 ± 9.92%) y mayormente en la zona vulvar (37.50 ± 9.68%). La neoplasia más frecuente en el ovario fue el tumor de células de la granulosa (47.6 ± 21.4%), en útero fue el leiomioma (50.0 ± 40.0%) y en vulva y vagina fue el tumor venéreo transm...

The aim of the study was to establish whether the presence of Cryptosporidium parvum in the dam is a risk factor for the presentation of the pathogen in the baby alpaca. The study included 698 alpaca dams and their offspring less than 30 days of age. The sampling took place from January till March 2007 in the localities of La Raya, Choquecota, Chillihua, Maranganí and Silli in Canchis province, Cusco, Peru. Fecal samples were collected from the rectum, processed using the Modified Ziehl-Neelsen stain and observed by microscopy. Risk analysis was done through logistic regressions. Results showed that a baby alpaca born from a positive dam to C. parvum was 2.1 times more likely to get infected with the parasite as compared with others born from a negative dam (p<0.05). Likewise, sex and presence of diarrhea were not significant, whereas place of breeding showed to be a protection facto...
