“…The large number of bilateral branches of the uterus is the main element used in species identification of the helminth (Fig. 1) (4). The eggs of the beef tapeworm are spherical with a thick dark brown cross-furrowed shell and an oncosphere with a 6-hooked embryo (1).…”

The aim of the present study is to analyse the dynamics of the distribution of taeniasis caused by the beef tapeworm (Taeniarhynchus saginatus) among the population of Bulgaria for the period 2008-2017. Material and methods. The analysis is based on laboratory and clinical data on patients diagnosed with taeniarhynchosis in DPTM at NCIPD, as well as data from epidemiological studies carried out by RHIs in accordance with the current legislation in the country. Results. For the studied period, cases of human taeniarhynchosis were reported from 21 districts of the country, with 246 infected persons. The areas with the highest number of cases during the whole period were Shumen – 14.6%, Plovdiv – 13.8%, Targovishte – 10.9 and Sofia – 10.6%. Annual morbidity ranges from 0.63 per 100 000 (2008) to 0.23 per 100 000 (2017), with average morbidity of 0.37% 000. The prevalence was higher among female subjects (61%), and the distribution by age showed a significantly higher incidence in adults (88%) compared to the group of children and adolescents (22%). The most affected were the age groups 35-39 (11.79%) and 55-59 (11.38%) years. Patients of different ethnic origin represent 54% of cases. Conclusion. Data from our study shows that cases of taeniarhynchosis, even though sporadic, are reported annually in the country. The distribution is highest in regions with well-developed private livestock farming and high rate of home meat production without veterinary control. Poor health literacy of the population resulting in environmental contamination with human excreta and the possibility of infection of intermediate hosts, as well as consumption of uncooked homemade products and insufficient veterinary health control mainly contribute to the endemic spread of taeniarhynchosis in the country.

“…Los gusanos tienen una musculatura circular y órganos internos (intestino, ovario, testículos) (46). Si se tienen dudas, es posible utilizar coloraciones de histoquímica tales como tricrómico de Van Gieson, tricrómico de Azan y orceína en el caso de ascaris lumbricoides (47), Van Gieson, Sudan Black, Gomori, PTAH de Mallory en enterobius vermicularis (48) y tricrómico de Goldner Masson en strongiloides stercolaris (42). También es posible usar ácido peryódico de Schiff (PAS), con el inconveniente que también marca en vegetales, aunque de manera distinta (Figura 6A).…”

la presencia de cuerpos vegetales en el estudio histopatológico, aunque es bastante usual, puede presentar problemas diagnósticos si se presentan en localizaciones poco usuales o con morfología que pueda llegar a generar un reto diagnóstico para el patólogo. Este debe ser reconocido apropiadamente ya que puede llevar a diagnósticos y tratamientos erróneos. Métodos: se llevó a cabo una búsqueda bibliográfica en las bases de datos: Pubmed, ScienceDirect, Scielo, ResearchGate y Google Académico. Se utilizaron palabras como “plants”, “vegetables”, “histopathology”, “cytology”, “drugs”, “infectious pathology” y “suture” en diferentes combinaciones. Resultados: los cuerpos vegetales pueden observarse en múltiples muestras, ya sea como un pasajero ocasional, contaminación o en casos de trauma. Algunos casos generan un reto diagnóstico, pues no siempre se está familiarizado con la histología vegetal, por lo cual puede ser fácilmente confundido con parásitos, hongos, cuerpos extraños no vegetales y medicamentos. Además, en especímenes de citología cervical y de células exfoliadas de pulmón pueden simular células malignas epitelialesConclusión: la ubicuidad de los vegetales en los especímenes y la posibilidad de contaminación hace que los patólogos diariamente estén expuestos a este tipo de elementos. El conocimiento básico de la histología vegetal, los patrones especiales y los diagnósticos diferenciales permite el diagnóstico adecuado, lo que guiará el mejor tratamiento para el paciente.

Foodborne Parasitic Diseases in the Neotropics – a review

Summary Within the Universal Declaration of Human Rights, it is stated that everyone has the right to an adequate standard of living, which ensures, as well as their family, health and well-being, and food, thereby ensuring adequate nutrition. One of the major threats to overcome this is to ensure food security, which becomes particularly challenging in developing countries due to the high incidence of parasitic diseases. The World Health Organization (WHO), considers it one of the main causes of morbidity, closely linked to poverty and related to inadequate personal hygiene, consumption of raw food, lack of sanitary services, limited access to drinking water and fecal contamination in the environment. It is estimated that more than a fifth of the world’s population is infected by one or several intestinal parasites, and that in many countries of Central and South America the average percentage of infected people is 45%, being Taenia solium, Echinococcus granulosus, Toxoplasma gondii, Cryptosporidium spp, Entamoeba histolytica, Trichinella spiralis, Ascaris spp, Trypanosoma cruzi and Fasciola hepatica some of the most important ones in the neotropics. One of the main reasons why these diseases are diffi cult to control is t he ignorance of their lifecycles, as well as symptoms and current epidemiology of the disease, which contributes to a late or erroneous diagnosis. The present work aims to discuss and make public the current knowledge as well as the general characteristics of these diseases to the general audience.
