The general conception of entrepreneurs is that strict environmental regulation, would result in the migration of entrepreneurs to countries where regulations are more flexible without affecting the productive capacity of enterprises; but according to recent research, companies with strict environmental regulations are more competitive by having plants with more efficient modern equipment and processes in the transformation of inputs, allowing optimization of costs, and minimizing waste.

Nine cases of pyometra occurred is reviewed retrospectively for a period of 15 years in the Archbishop Loayza Hospital Lima-Peru. The diagnosis was established clinically after observation of purulent material escaping through the cervical opening spontaneously or after dilation of the cervix. The average age was 52.5 years. Seven patients were post-menopausal age. The symptoms of malodorous vaginal discharge purulent discharge occurred in seven patients, five of whom attended with fever and general commitment. In no event associated with malignant disease of the cervix or uterus it is found. In six cases enlarged uterus was found and, in all cases, this was painful on palpation. EI preoperative diagnosis was made in four cases. Bacteriological results are limited by not having done anaerobic cultures. All patients received medical and surgical treatment, and its evolution was favorable....

The aim of this study was to determine the prevalence of intestinal parasites and the risk factors associated with zoonotic transmission in dogs with owner in the rural town of Retes, Huaral district (Lima, Peru). A descriptive cross-sectional study was carried out, where fecal samples of 47 dogs were collected and processed by simple direct methods, Willis-Molloy flotation technique and the rapid sedimentation technique modified by Lumbreras. The morphometric identification of the parasitic species was also done. The statistical analysis was performed by bivariate analysis with Chi square distribution. The prevalence of enteroparasitosis was 31.9%. Dipylidium caninum (12.8%), Toxocara canis (10.6%), Ancylostoma spp (4.3%), Cystoisospora canis (4.3%), Taenia spp (2.1%) were found. Monoparasitism was 76.7%, followed by biparasitism (13.4%) between helminths and protozoa. The feeding site ...

The aim of this study was to determine the prevalence, average intensity and mean abundance of ectoparasites in domestic pigeons (Columba livia). A total of 29 specimens were analyzed (17 males and 12 females). External surface of head, neck, chest, back and wings were examined, determining that 93.1% (14.9 ± 15.8 of total mean abundance) of pigeons were infected with one or more ectoparasites. All males and 83.3% of females were parasitized. Seven species of ectoparasites were identified, where five correspond to Order Mallophaga (Columbicola columbae [82.8%], Menopon gallinae [48.3%] Goniodes gigas [31%], Menacanthus stramineus [17.2%] and Lipeurus caponis [6.9%]), one to Order Diptera (Pseudolynchia canariensis [10.3%]), and one to Order Siphonapetra (Echidnophaga gallinacea [3.4%]). The largest number of mallophagans was found on the feathers of the wings and chest. Among associatio...

El objetivo del presente trabajo fue determinar la prevalencia, intensidad media y abundancia media de ectoparásitos en palomas domésticas (Columba livia) comercializadas en un mercado de la ciudad de Lima, Perú. Se analizaron 29 ejemplares (17 machos y 12 hembras). Se inspeccionó la superficie externa de la cabeza, cuello, pecho, dorso y alas, determinando que el 93.1% (14.9 ± 15.8 de abundancia media total) de las palomas estuvieron infestadas con uno o más ectoparásitos; asimismo, el 100 de los machos y 83.3% de las hembras estuvieron parasitados. Se identificaron siete especies de ectoparásitos, de los cuales cinco corresponden al Orden Mallophaga (Columbicola columbae [82.8%], Menopon gallinae [48.3%] Goniodes gigas [31%], Menacanthus stramineus [17.2%] y Lipeurus caponis [6.9%]), uno al Orden Diptera (Pseudolynchia canariensis [10.3%]), y uno al Orden Siphonapetra (Echidnop...
