Prolapso de hemipene y hemipenectomía en un gecko leopardo (Eublepharis macularius)

Copulatory organ prolapse is a condition more frequently observed in chelonians and ophidians than in lizards. Most common causes are infections, forced separation during mating and inflammation associated to the use of probes for sex determination. Moreover, many other predisposing factors are described (hypocalcaemia, urolithiasis, etc.), but etiological diagnosis is rarely achieved. A four years old leopard gecko (Eublepharis macularius) was received presenting unilateral hemipenile prolapse. Medical therapy was performed using 50 % dextrose baths and prednisone (2 mg/kg) during 24 hours, but it was unsuccessful. Due to the fact that the prolapsed hemipenis showed signs of necrosis, surgical resection was performed. The patient was anesthetized using the combination ketamine (5 mg/kg), dexmedetomidine (0.1 mg/kg), and midazolam (1 mg/kg); also, lidocaine (4 mg/ kg) was administered for local block, whereas atipamezole (0.5 mg/kg) was used for antagonizing dexmedetomidine. The used anesthetic protocol allowed an adequate surgical management. Hemipenectomy solved the problem without any observed complication.El prolapso del órgano copulatorio es una afección más frecuentemente observada en quelonios y ofidios que en saurios. Las causas más comunes son infecciones, separación forzada durante la cópula e inflamación asociada al uso de sondas para determinación del sexo. Además, se han descrito muchas otros factores asociados (hipocalcemia, urolitiasis), pero rara vez se logra llegar al diagnóstico etiológico. Un gecko leopardo (Eublepharis macularius) de cuatro años de edad fue recibido presentando prolapso unilateral de hemipene. Se realizó tratamiento médico usando baños en dextrosa 50 % y prednisona (2 mg/kg) durante 24 horas, pero éste no fue exitoso. Debido a que el hemipene prolapsado presentó signos de necrosis, se realizó la resección quirúrgica. El paciente fue anestesiado empleando la combinación ketamina (5 mg/kg), dexmedetomidina (0,1 mg/kg) y midazolam (1 mg/kg). Además, se administró lidocaína (4 mg/kg) como bloqueo local y se usó atipamezol para antagonizar la dexmedetomidina. El protocolo anestésico empleado permitió el manejo quirúrgico adecuado.

First Case of Systemic Coronavirus Infection in a Domestic Ferret (Mustela putorius furo) in Peru.

A domestic ferret from Lima, Peru, died after ten days of non-specific clinical signs. Based on pathology, immunohistochemistry and molecular analysis, ferret systemic coronavirus (FRSCV)-associated disease was diagnosed for the first time in South America. This report highlights the potential spread of pathogens by the international pet trade

Native rodent species are unlikely sources of infection for Leishmania (Viannia) braziliensis along the Transoceanic Highway in Madre de Dios, Peru.

An estimated 2.3 million disability-adjusted life years are lost globally from leishmaniasis. In Peru's Amazon region, the department of Madre de Dios (MDD) rises above the rest of the country in terms of the annual incidence rates of human leishmaniasis. Leishmania (Viannia) braziliensis is the species most frequently responsible for the form of disease that results in tissue destruction of the nose and mouth. However, essentially nothing is known regarding the reservoirs of this vector-borne, zoonotic parasite in MDD. Wild rodents have been suspected, or proven, to be reservoirs of several Leishmania spp. in various ecosystems and countries. Additionally, people who live or work in forested terrain, especially those who are not regionally local and whose immune systems are thus naïve to the parasite, are at most risk for contracting L. (V.) braziliensis. Hence, the objective of this study was to collect tissues from wild rodents captured at several study sites along the Amazonian segment of the newly constructed Transoceanic Highway and to use molecular laboratory techniques to analyze samples for the presence of Leishmania parasites. Liver tissues were tested via polymerase chain reaction from a total of 217 rodents; bone marrow and skin biopsies (ear and tail) were also tested from a subset of these same animals. The most numerous rodent species captured and tested were Oligoryzomys microtis (40.7%), Hylaeamys perenensis (15.7%), and Proechimys spp. (12%). All samples were negative for Leishmania, implying that although incidental infections may occur, these abundant rodent species are unlikely to serve as primary reservoirs of L. (V.) braziliensis along the Transoceanic Highway in MDD. Therefore, although these rodent species may persist and even thrive in moderately altered landscapes, we did not find any evidence to suggest they pose a risk for L. (V.) braziliensis transmission to human inhabitants in this highly prevalent region

Proyecto Glencross : Energía eólica y solar para escuela rural

El presente trabajo presenta los avances logrados en la instalación de los componentes de un sistema eólico – solar para suministro aislado en una Escuela Rural en el marco de un proyecto PFIP (Proyectos Federales de Innovación Productiva) con financiamiento del Consejo Federal de Ciencia y Tecnología (CoFeCyT), como así también de un sistema de medición específico para evaluar el funcionamiento de los equipos. Se utilizan los equipos eólicos para la carga de un banco de baterías de 48V y luego se suministra 220V a través de un convertidor. El sistema solar, por lo riguroso del clima y la latitud (sur de la provincia de Santa Cruz), se utilizará para el precalentamiento de agua de los termotanques, con vistas a lograr una disminución del consumo de gas licuado de petróleo. Se proporcionan detalles de los aspectos técnicos y algunos datos preliminares relevados por el sistema.This work presents the almost complete installation of a hybrid wind-solar power system for a rural school in South Patagonia, with the addition of a complex measurement system (SISMED/C) which is expected to allow for the evaluation of performance and operation of the overall system. The electricity supply has operated successfully up to date. The construction of the systems includes great level of local and regional integration of components, which is in line with the objectives of the CoFeCyT (Federal Science and Research Commission) and the University which provide the financial support. It is expected that such equipment will contribute to better living and educational conditions in this rural environment with extreme climate parameters.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES

Fecal contamination of drinking water within peri-urban households, Lima, Peru.

We assessed fecal contamination of drinking water in households in 2 peri-urban communities of Lima, Peru. We measured Escherichia coli counts in municipal source water and, within households, water from principal storage containers, stored boiled drinking water, and water in a serving cup. Source water was microbiologically clean, but 26 (28%) of 93 samples of water stored for cooking had fecal contamination. Twenty-seven (30%) of 91 stored boiled drinking water samples grew E. coli. Boiled water was more frequently contaminated when served in a drinking cup than when stored (P < 0.01). Post-source contamination increased successively through the steps of usage from source water to the point of consumption. Boiling failed to ensure safe drinking water at the point of consumption because of easily contaminated containers and poor domestic hygiene. Hygiene education, better point-of-use treatment and storage options, and in-house water connections are urgently needed
