RESUMO

The increasing occurrence of human cysticercosis, a zoonotic neglected disease, is challenging the traditional prevention and control paradigm and calling for One Health (OH) solutions in industrialized countries. OH solutions for health interventions are increasingly being used to capture expected and unexpected outcomes across people, animals, and the environment. The Network for Evaluation of One Health (NEOH) proposes an evidence-based framework, relying on systems and mixed methods approaches to evaluate the One Health-ness. In this case study, this tool is used to evaluate the design of the Observatory of Taeniasis and Cysticercosis, as an example of intersectorial collaboration for surveillance in Portugal. The OH Initiative (drivers and expected outcomes) and its system (boundaries, aim, dimensions, actors, and stakeholders) were described. The different aspects of this Initiative were scored with values from 0 (=no OH approach) to 1 (=perfect OH approach). The OH index was 0.31. Its OH ratio is 1.98. Overall scores were as follows: OH thinking 0.75; OH planning 0.60; OH working 0.60; OH sharing 0.35; OH learning 0.50; and systemic organization 0.50. Operational levels of the Initiative are the main strengths, indicating a comprehensive multidimensional innovative approach and transdisciplinarity. Critical issues in the supporting infrastructure were observed, related to communication, learning and organizational gaps in the project, with the evaluation being conducted as the project is being designed and implemented. The strengths and weaknesses detected may be used to refine the Initiative. This case study therefore exemplifies and supports OH assessment also for ongoing projects, at design and early implementation stages for guiding and guaranteeing an OH-oriented perspective.

RESUMO

The Authors describe a severe vasculitis with fibrinoid necrosis of the meningeal arteries observed in two brains of indigenous short-horn zebu (Bos indicus) cattle, with bovine cerebral theileriosis (BCT) caused by a tick-transmitted hemoprotozoan, Theileria taurotragi, from Northern Tanzania. In the Author's opinion, the role of T. taurotragi infection in the angiocentric and angiodestructive detected features remains to be evaluated. A possible immunopathologic cancerous mechanism, secondary to the lymphoid deregulation, could be involved. This report suggests further studies to better characterize the lymphoid cell involvement in the pathogenesis of the meningeal vascular lesions by T. taurotragi.

RESUMO

OBJECTIVE: To establish priorities for zoonoses surveillance, prevention, and control in Bogotá, Colombia. METHODS: A Delphi panel of experts in veterinary and human medicine was conducted using a validated prioritization method to assess the importance of 32 selected zoonoses. This exercise was complemented by a questionnaire survey, using the knowledge, attitudes, and practices (KAP) methodology, administered in 19 districts of Bogotá from September 2009 to April 2010 to an at-risk population (workers at veterinary clinics; pet shops; butcher shops; and traditional food markets that sell poultry, meat, cheese, and eggs). A risk indicator based on level of knowledge about zoonoses was constructed using categorical principal component and logistic regression analyses. RESULTS: Twelve experts participated in the Delphi panel. The diseases scored as highest priority were: influenza A(H1N1), salmonellosis, Escherichia coli infection, leptospirosis, and rabies. The diseases scored as lowest priority were: ancylostomiasis, scabies, ringworm, and trichinellosis. A total of 535 questionnaires were collected and analyzed. Respondents claimed to have had scabies (21%), fungi (8%), brucellosis (8%), and pulicosis (8%). Workers with the most limited knowledge on zoonoses and therefore the highest health risk were those who 1) did not have a professional education, 2) had limited or no zoonoses prevention training, and 3) worked in Usme, Bosa, or Ciudad Bolívar districts. CONCLUSIONS: According to the experts, influenza A(H1N1) was the most important zoonoses. Rabies, leptospirosis, brucellosis, and toxoplasmosis were identified as priority diseases by both the experts and the exposed workers. This is the first prioritization exercise focused on zoonoses surveillance, prevention, and control in Colombia. These results could be used to guide decision-making for resource allocation in public health.


OBJETIVO: Establecer prioridades en la vigilancia, la prevención y el control de las zoonosis en Bogotá, Colombia. MÉTODOS: Se constituyó un grupo Delfos de expertos en veterinaria y medicina que utilizó un método validado de asignación de prioridades con objeto de evaluar la importancia de 32 zoonosis seleccionadas. Esta actividad se complementó con una encuesta de cuestionario que utilizó el método de conocimientos, actitudes y prácticas (CAP) y que se administró en 19 distritos de Bogotá, de septiembre del 2009 a abril del 2010, a una población en situación de riesgo (empleados de consultorios veterinarios, tiendas de mascotas, carnicerías y mercados de alimentos tradicionales que venden aves de corral, carne, queso y huevos). Se creó un indicador de riesgo basado en el nivel de conocimiento acerca de las zoonosis mediante análisis de componentes principales para datos categóricos y análisis de regresión logística. RESULTADOS: En el grupo Delfos participaron doce expertos. Las enfermedades calificadas como de mayor prioridad fueron la gripe A(H1N1), la salmonelosis, la infección por Escherichia coli, la leptospirosis y la rabia. Las enfermedades calificadas como de menor prioridad fueron la anquilostomiasis, la escabiosis, la tiña y la triquinosis. Se recopilaron y se analizaron un total de 535 cuestionarios. Los encuestados informaron de que habían padecido escabiosis (21%), infecciones por hongos (8%), brucelosis (8%) y pulicosis (8%). Los trabajadores cuyos conocimientos sobre zoonosis eran más limitados y por consiguiente estaban sometidos a un mayor riesgo para su salud fueron los que 1) no tenían una formación profesional, 2) contaban con poca o nula capacitación en materia de prevención de zoonosis, y 3) trabajaban en las localidades de Usme, Bosa o Ciudad Bolívar. CONCLUSIONS: Según los expertos, la gripe A(H1N1) fue la zoonosis más importante. La rabia, la leptospirosis, la brucelosis y la toxoplasmosis fueron consideradas como enfermedades prioritarias tanto por los expertos como por los trabajadores expuestos. Esta es la primera actividad de asignación de prioridades centrada en la vigilancia, la prevención y el control de las zoonosis en Colombia. Estos resultados podrían servir de guía en la toma de decisiones para la asignación de recursos en salud pública.

RESUMO

OBJETIVO: To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers. MÉTODOS: A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out. RESULTADOS: Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses. CONCLUSÕES: Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.


OBJECTIVE: Analisar fatores associados à baixa percepção de risco de zoonoses e identificar as lacunas no conhecimento sobre a transmissão e prevenção de zoonoses em trabalhadores imigrantes e italianos. METHODS: Estudo transversal com 175 trabalhadores da indústria agropecuária e agroalimentar em Piemonte, Itália. Os dados foram obtidos por meio de questionário semiestruturado baseado em estudo sobre conhecimentos, atitudes e práticas. Foram calculadas proporções, com uso de teste qui-quadrado e odds ratio para estimar associações. Oito entrevistas individuais com informantes-chave em matéria de imigração e saúde pública foram realizadas. RESULTS: Cerca de 47% dos trabalhadores eram italianos e 53%, imigrantes, provenientes da Romênia, Marrocos, Albânia, Índia, China, Argentina, Peru, Macedônia, Costa do Marfim, Ucrânia e Colômbia. Houve diferenças significativas na menor percepção do risco no trabalho (p = 0,001). Observou-se associação entre falta de conhecimentos corretos sobre zoonoses e ser imigrante (OR = 4,1; IC95% 1,7;9,8; p ≤ 0,01), trabalhar na indústria pecuária (OR = 2,9; IC95% 1,2;6,8; p = 0,01) e ser um trabalhador não qualificado (OR = 4,4; IC95% 1,2;15,4; p = 0,01). Outra forte associação ocorreu entre ser imigrante e ter emprego de baixa qualificação (OR = 6,7; IC95% 2,9;15,4; p ≤ 0,01). Maior frequência de comportamentos de risco e menor nível de conhecimento sobre zoonoses foram encontrados no grupo dos imigrantes asiáticos. CONCLUSIONS: Foram observadas diferenças na percepção de risco de zoonoses entre os grupos participantes. O status de imigrante pode ser considerado fator de risco para ter baixa percepção de risco e menor nível de conhecimento das zoonoses no trabalho. Existe relação entre esse conhecimento específico de zoonoses e falta de formação e instrução entre as populações migrantes. É necessário desenvolver programas de educação sobre a prevenção de zoonoses entre a população imigrante.

RESUMO

Ovine pulmonary adenocarcinoma (OPA) is a contagious disease caused by jaagsiekte sheep retrovirus (JSRV). In the three studies performed, we have obtained data of the importance of colostrum/milk (C/M) in the transmission of JSRV. In the first study, a group of sheep from a flock with a long history of OPA, samples from colostrum and peripheral blood leucocytes (PBLs) were collected. Two specific PCRs (U3-LTR and env of the JSRV) were carried out. Using U3PCR 8/34 sheep were positive in colostrum whereas with envPCR 7/34 were positive. From these animals only one was positive with U3PCR in the PBLs. Evidence of the transmission of JSRV infection by C/M was obtained in two more separate studies. In the second study, PBLs from five lambs from JSRV+ ewes and two from JSRV-ewes were tested by the U3PCR. They were fed C/M by their mothers during 3 months and slaughtered 7 months after birth. Three out of five lambs from the JSRV+ sheep become PBL positive at 3-4 months old and the other two were also positive at 4-6 months of age. One lamb of the JSRV-sheep became also PBL positive at an age of 3 months. In the third study, a group of lambs from JSRV negative mothers were fed with C/M from JSRV+ sheep and housed in separate unit. For comparison, another group of the same origin and maintained in another different unit, were fed with C/M containing a JSRV virus preparation. All lambs were blood sampled monthly and JSRV infection was detected as early as 15 days and several times onwards in both groups. Control groups fed with C/M from JSRV free flock and JSRV blood test negative sheep were always negative. Together these results indicate that suckling is an important natural transmission route for JSRV.
