RESUMO

Abstract Distribution pattern and relative abundance of the agricultural rodent pests of rain-fed and irrigated areas of district Swat Khyber Pakhtunkhwa, Pakistan were recorded from April 2011 to November 2013 using wire mesh live traps. A total of 350 rodents (269 Rattus rattus and 81 Mus musculus) were captured under 2268 trap nights (trap success: 0.15). Regression of daily captures on cumulative captures revealed an estimate of 350 rodents from all the sampled structures with an average of 21.8 rodents per crop field. House rats (R. rattus; 76.8% of captures) were numerically dominant in almost all types of agricultural fields, and were significantly different from the mice (Mus musculus; 23.1% of captures). Both species were found together in some fields. The sex ratio revealed that males outnumbered the females in both of the reported species.


Resumo O padrão de distribuição e a abundância relativa de pragas de roedores agrícolas nas áreas irrigadas e irrigadas do distrito Swat Khyber Pakhtunkhwa, Paquistão foram registrados de abril de 2011 a novembro de 2013 usando armadilhas vivas de malha de arame. Um total de 350 roedores (269 Rattus rattus e 81 Mus musculus) foram capturados em 2268 noites de armadilha (sucesso da armadilha: 0,15). A regressão das capturas diárias em capturas cumulativas revelou uma estimativa de 350 roedores de todas as estruturas amostradas, com uma média de 21,8 roedores por campo agrícola. Os ratos domésticos (R. rattus; 76,8% das capturas) foram numericamente dominantes em quase todos os tipos de campos agrícolas e foram significativamente diferentes dos camundongos (Mus musculus; 23,1% das capturas). Ambas as espécies foram encontradas juntas em alguns campos. A proporção de sexo revelou que os machos superaram as fêmeas em ambas as espécies relatadas.

RESUMO

Abstract Infection caused by geo-helminth parasites are called geohelminthiasis are one of the global health problems. Vegetables eaten raw is the principal source of transmission of geo-helminth parasites. Pakistani people believe that eating raw vegetables are a significant source to get important vitamins and minerals. Based on the high incidence of pathogenic parasites and cultivating different vegetable types in the study areas, we conducted this study to evaluate the geo-helminth contamination of raw vegetables in northwest Khyber Pakhtunkhwa, Pakistan. This is a descriptive study comprised, 1942 samples of 25 various types of vegetables. The samples were examined in physiological saline solution using sedimentation and centrifugation methods. The findings were analyzed by Graph-Pad version 5. P value less than 0.05 (95% CI) was considered significant. Results showed that 16.5% (n=322) of all vegetables were contaminated with one or more type of geo-helminth parasites. Garlic was the highest (35%) and cauliflower the lowest (4%) contaminated samples respectively. Ascaris lumbricoides was the most common geo-helminth found followed by hook worm species while Trichuris trichura was the least in all the vegetable samples. Leafy vegetables were highly contaminated 25.3% than vegetables with root parts 21.2% and fruity 9.09%. More than half of the contaminated vegetables were contaminated with single species of geo-helminth (P<0.05) while less than half with multiple types of geo-helminth contamination. Ninety two vegetables samples were contaminated with 2 species of parasites (P<0.05) and 45 with 3 (P>0.05) species of geo-helminth parasites. Education level of vendors and means of display were not significantly associated while types of vegetable used were significantly associated with the prevalence of parasites. The findings of this study provide evidence that consumption of raw vegetable has a high risk of acquiring geo-helminth infections. The authors believe that preventing the human to enter to the vegetable farmland for defecation, avoiding the irrigation of agricultural fields via night soil, and educating the people on proper washing and cooking of vegetables may be useful in reducing parasitic infections.


Resumo As infecções causadas por parasitas geo-helmínticos são chamados de geohelmintíases e são um dos problemas de saúde globais. Os vegetais comidos crus são a principal fonte de transmissão dos parasitas geo-helmínticos. O povo paquistanês acredita que comer vegetais crus é uma fonte significativa para obter vitaminas e minerais importantes. Com base na alta incidência de parasitas patogênicos e no cultivo de diferentes tipos de vegetais nas áreas de estudo, conduzimos este estudo para avaliar a contaminação por geo-helmintos de vegetais crus no noroeste de Khyber Pakhtunkhwa, Paquistão. Trata-se de um estudo descritivo composto por 1942 amostras de 25 tipos diversos de vegetais. As amostras foram examinadas em solução salina fisiológica utilizando métodos de sedimentação e centrifugação. Os achados foram analisados ​​pelo Graph-Pad versão 5. O valor de P menor que 0,05 (IC 95%) foi considerado significativo. Os resultados mostraram que 16,5% (n = 322) de todas as hortaliças estavam contaminadas com um ou mais tipos de parasitas geo-helmínticos. O alho foi a amostra mais contaminada (35%) e a couve-flor a menos (4%), respectivamente. Ascaris lumbricoides foi o geo-helmíntico mais comum encontrado, seguido por espécies de verme-anzol, enquanto Trichuris trichura foi o menos encontrado em todas as amostras de vegetais. Os vegetais folhosos foram altamente contaminados 25,3% do que os vegetais com partes de raiz 21,2% e frutados 9,09%. Mais da metade dos vegetais contaminados estavam contaminados com uma única espécie de geo-helmintos (P <0,05), enquanto menos da metade com vários tipos de contaminação com geo-helmintos. Noventa e duas amostras de vegetais estavam contaminadas com 2 espécies de parasitas (P <0,05) e 45 com 3 (P> 0,05) espécies de parasitas geo-helmínticos. O nível de escolaridade dos vendedores e os meios de exibição não foram significativamente associados, enquanto os tipos de vegetais usados ​​foram significativamente associados à prevalência de parasitas. Os resultados deste estudo fornecem evidências de que o consumo de vegetais crus tem um alto risco de adquirir infecções por geo-helmintos. Os autores acreditam que impedir que o ser humano entre na terra de hortaliças para defecação, evitar a irrigação de campos agrícolas via solo noturno e educar as pessoas sobre a lavagem e cozimento adequados de vegetais pode ser útil na redução de infecções parasitárias.

RESUMO

OBJECTIVE: There is scarcity of information on the prevalence of female genital tuberculosis (FGTB) in the community. The present study was carried out to estimate the prevalence of FGTB, its risk factors and associated clinical features. STUDY DESIGN: Community-based cross-sectional survey. METHODS: This study was carried during October 2011 and May 2014 in the Andaman Islands. A total of 13,300 women aged 20-59 years were primarily screened using a structured questionnaire. About 721 (5.4%) were found initially eligible for screening for genital tuberculosis by clinical examination and specimen collection for laboratory tests but only 460 (63.8%) expressed their willingness. Endometrial specimens were collected from 405 (88%) subjects. The association of the potential risk factors with genital tuberculosis was tested by Chi-squared test. A similar analysis was performed to identify clinical features associated with genital tuberculosis. RESULTS: The estimated prevalence of FGTB was 45.1 cases per 100,000 women (95% confidence interval [CI]: 16.6-98.1). Infertility and oligomenorrhoea were identified as clinical features associated with FGTB. Past history of tuberculosis and history of close contact with tuberculosis cases were identified as risk factors. CONCLUSIONS: This study shows the prevalence of FGTB among the female population of the Andaman Islands. Though the estimated prevalence was close to the expected prevalence, but as only 63.8% of the eligible women could be adequately screened, a much higher prevalence of FGTB could not be ruled out. Infertility, oligomenorrhoea, past history of tuberculosis and contact with tuberculosis case were identified as factors associated with genital tuberculosis.
