Five specimens of Hoplerythrinus unitaeniatus «shuyo» (Erythrinidae) and one of Pterodoras. granulosus «cahuara» (Doradidae) were assessed in Yurimaguas district, Alto Amazonas, Loreto, Peru in February 20014. A larva of the trematode Ithyoclinostomum dimorphum and 13 larvae of Sphincterodiplostomum musculosum in H. unitaeniatus in the visceral surface, and 18 adult of Dadaytrema oxycephala from the small bowel of P. granulosus were found. This is the first report of metacercariae of I. dimorphum and S. musculosum in Peru. H. unitaeniatus is a new host for S. musculosum. D. oxycephala in P. granulosus is reported in Peru.

In Condebamba Valley (Cajamarca) between February and July 1973; 69 crabs Pseudothelphusa chilensis were collected, of them (34 males and 35 females) 22 (64.7%) males and 29 (28.85%) females were infected with metacercariae, this results are consistent with Cuba et al. (1974) report.

Fasciolosis is recognised as a major problem in dairy cattle in Cajamarca, Peru. The infection has an annual cycle, with the major period of infection from January to March. A control programme, involving two doses of the fasciolicide triclabendazole aimed at reducing the passage of Fasciola hepatica eggs on to the pasture, together with the use of the molluscicide, niclosamide, was evaluated against traditional treatment programmes. The double treatment regimen did not significantly reduce the overall parasite burden, as measured by faecal egg counts, but did control the parasites to a level similar to that achieved by traditional programmes averaging 3-7 treatments per year. The cows' eosinophil counts and serum liver enzyme activities were significantly lower than in animals treated by the traditional programmes. The use of niclosamide in addition to the triclabendazole treatments gav...

In May 2005 and April 2006, in the region of Khastor, Potosi, Bolivia, a female pampas cat (Leopardus colocolo) was captured. The efficacy of a protocol for chemical immobilization for animal handling, clinical evaluation and collection of biological samples was evaluated. It was used ketamine hydrochloride (KH) + medetomidine hydrochloride (MH), and antagonized the latter with atipamezole (AH). In 2005 were administered 4.38 mg/kg of KH + 0.04 mg/kg of MH, requiring 2 successive doses of 1.76 mg/kg of KH. In 2006 were administered 5.0 mg/kg of KH + 0.05 mg/kg of MH. MH was antagonized with 0.22 and 0.25 mg/kg of AH in 2005 and 2006 respectively. The induction time and chemical immobilization in both campaigns were very similar but the recovery time from anesthesia in 2006 was shorter than in 2005. The clinical evaluation indicated adequate health and physical status. The hemograms showe...

Perú es un destino turístico cada vez más popular que representa un riesgo para los viajeros debido a las enfermedades endémicas transmitidas por vectores (VBD). El objetivo de nuestro estudio fue determinar qué factores están asociados con la recepción de consejos previos a los viajes (PTA) para VBD entre los viajeros que visitan Cuzco, Perú. Se realizó un análisis secundario de corte transversal basado en datos de una encuesta entre viajeros que salían de Cuzco en el Aeropuerto Internacional Alejandro Velazco Astete durante el período de enero a marzo de 2012. A partir de los 1819 viajeros incluidos en el estudio original, 1717 se incluyeron en el análisis de datos secundarios. De estos participantes, el 42,2% recibió PTA y el 2,9% recibió información sobre enfermedades transmitidas por vectores, incluida la fiebre amarilla (1,8%), la malaria (1,6%) y el dengue (0,1%). ...

En mayo de 2005 y abril de 2006, en la región de Khastor, Potosí, Bolivia, se realizó la captura y recaptura de un ejemplar hembra de gato de las pampas (Leopardus colocolo) a quien se le colocó un radiocollar. Se probó la eficacia de un protocolo de inmovilización química para maniobras, evaluación clínica y colecta de muestras biológicas para estudios de laboratorio. Se utilizó una combinación de clorhidrato de ketamina (KH) + clorhidrato de medetomidina (MH), y este último se antagonizó con atipamezole (AH). En el 2005 se empleó 4.38 mg/kg de KH + 0.04 mg/kg de MH, requiriendo 2 dosis sucesivas de 1.75 mg/kg de KH. En el 2006 se empleó 5.0 mg/kg de KH + 0.05 mg/kg de MH. El MH se antagonizó con 0.22 y 0.25 mg/kg de AH en el 2005 y 2006, respectivamente. El tiempo de inducción e inmovilización química en ambas campañas fue similar pero el tiempo de recuperación an...

Fasciolosis is recognised as a major problem in dairy cattle in parts of Peru. A longitudinal study of dairy cattle in Cajamarca, Peru was used to determine the annual pattern of infection with Fasciola hepatica. After a gradual increase from January, peak egg production occurred in August/September and then dropped rapidly. Indirect indicators of infection, eosinophil counts and serum liver-enzyme activities, indicated that the major period of new infection in cattle occurred from December to May each year. Examination of snails demonstrated that, although there was no clear annual cycle in snail abundance, the majority of snails infected with cercariae were found between January and March. Climatological data indicated that there was sufficient moisture for development of the parasite during a limited period each year, coinciding with the period of maximum abundance of cercaria-infecte...

Objective: To establish whether the perception of abuse was related to the prevalence of stress in the year 2024. Material and Methods: The type of study was quantitative, cross-sectional and correlational in design. 85 students were evaluated, they were selected by non-probabilistic sampling for convenience, a significant p < 0.05 was used as a parameter to determine the relationship between variables. Results: a prevalence of high levels of stress of 82.3% was found in the students, which is related to different types of abuse, academic abuse with a significant correlation with a (p = 0.020); psychological abuse with a (p = 0.0282); On the contrary, physical abuse with a (p = 0.52) and sexual abuse with a (p = 0.2308) showed no significant correlation. Sex and year of study demonstrated a significant relationship with stress levels, with values of p = 0.0274 and p = 0.0492, respectivel...

A significant relationship was found between sex and anxiety (p=0.004), financial suppo...

Objectives: to determine the relationship between addiction to social networks and the presence of mental disorders in medical students at a university in Cajamarca in the year 2024. Method: the study had a quantitative approach, non-experimental, cross-sectional and correlational design. It involved the participation of 114 students, who filled out a survey consisting of two questionnaires: “Addiction to Social Networks” and Depression, Anxiety and Stress Abbreviated Scales (DASS-21), which are validated with Combrach’s alpha 0,95 and 0,933 respectively. Results: respondents are mostly aged 16-20 years and 54,4 % were female. A high prevalence level (98,2 %) of addiction to social networks was calculated; meanwhile, the prevalence of anxiety, depression and stress were 51,2 %, 46,5 % and 43 %, respectively. A significant association was found between depression and stress with res...
