“…Dados do presente estudo demonstram uma alta prevalência de cisticercose em alguns lotes de bovinos coletados. No Brasil, dependendo da região, a cisticercose bovina é considerada umas das principais ou a principal doença parasitária diagnosticada no exame post mortem em bovinos (Pfuetzenreiter & Ávila--Pires 2000, Costa et al 2006, 2012, Tessele et al 2013. As ocorrências regionais em nosso país registraram percentu- ais de 4%-45% nas propriedades rurais, com alguns lotes chegando próximo a 100%, semelhante ao observado neste estudo.…”

ABSTRACT.-Panziera W., Vielmo A., Bianchi R.M., Andrade C.P., Pavarini S.P., Sonne L., Soares J. Bovine cysticercosis is an important zoonotic parasitic disease with high prevalence in several regions of Brazil. Considering the need of improvement of the accuracy of diagnosis of these lesions, as well as the difficulty of classification of the cysts, this study aimed to correlate gross and histopathological changes of bovine cysticercosis and to use polymerase chain reaction (PCR) as an aid in their identification. Cystic and nodular lesions from cattle, grossly compatible with cysticercosis, were sampled in slaughterhouses from Rio Grande do Sul State. Lesions were allotted in one of the following groups. Group 1: viable cysticercus; Group 2 (subdivided 2a e 2b): degenerating cysticercus with a potentially viable scolex; and Group 3: dead cysticercus (mineralized). The gross and microscopic aspects of every cysticerci of each group were compared. Two hundred and thirty two cysts and nodules compatible with cysticercus were sampled from 127 bovine. Twenty six of those lesions were tested with PCR. Out of 127 cattle, 46 (36.2%) had more than one cyst and the remaining 81 (63.8%) had on cyst each. Myocardium was the most frequently involved anatomical site (55.9%), followed by masseter muscle (22.8%). When there was more than one organ involved in the same bovine, myocardium a master muscle sum up 11 cases (8.6%). In general, the average of cysticercosis frequency was 10-15%. However the average in some cattle lots was in excess of 50%, 80% and 90%. Morphologically, 232 cysticerci were classified in three groups. In Group 1, 23 cysticerci (9.9%) were considered viable and were characterized by cysts of translucent or slightly opaque wall, containing clear and a white point (scolex) within the cyst. Histologically, the cysts consisted of a membrane from which a scolex of Taenia saginata invaginated. One hundred and fifty six cysts (67.2%) were allotted in Group 2; grossly these cysts revealed two different morphological patterns. In 111 (71.1%) cases of Group 2 (Group 2a) nodular caseous lesions were observed. Histologically, the cysts were characterized by nodules consisting by a central area containing the scolex and membrane, both degenerated, and caseous necrosis. In the remaining 45 (28.9%) cases of Group 2 (Group 2b), lesions were also caseous; however, at cut surface the cysts had a central hole amidst the caseous material. The microscopic aspect of the 45 cysts included in the second was similar to that of the first pattern. However in eight (17.8%) of the 45 cysts only a viable parasitic membrane was observed and in one cyst the membrane and viable scolex were observed. In the remaining 36 cases (80%), the cysts consisted of a central area containing both degenerated membrane and scolex, and caseous necrosis. In Group 3, 53 dead cysts (mineralized) (22.9%) were found among the total of 232 cysts. The 1 Recebido em 20 de fevereiro de 2017.Aceito para publicação em 28 de março de 2017.

“…Apesar da lesão de cisticercose não ser relevante no estudo, é uma doença parasitária considerada zoonose e apresenta grande importância à saúde pública (PFUETZENREITER & ÁVILA-PIRES, 2000;SANTOS et al, 2008;KHANIKI, 2010;SANTOS et al, 2010). Nos suínos, o desenvolvimento completo dos cisticercos se dá entre 60 e 75 dias após a infecção e a larva permanece viável para parasitar o homem durante anos (SILVA, 2004).…”

RESUMOO objetivo deste trabalho foi mensurar as perdas causadas pela condenação de órgãos suínos em matadouros sob fiscalização do serviço de inspeção municipal (SIM) em Santa Maria, RS durante 12 meses consecutivos. O estudo foi realizado através do levantamento de dados de matadouros do município de Santa Maria, Rio Grande do Sul, Brasil, junto ao SIM. Os dados registrados foram o número de animais abatidos, número de órgãos condenados e principais lesões que levaram as condenações, no período de outubro de 2010 a setembro de 2011. Durante o período de avaliação, 6.193 animais foram abatidos. Observou-se que 5.511 órgãos foram condenados, com destaque as condenações por lesões de aspiração de sangue (n = 1.231), migração larval (n = 991) e cisto renal (n = 807). A pesquisa revelou que anualmente R$ 11.955,66 é desperdiçado com condenação de órgãos. A migração larval no fígado foi a principal lesão que contribuiu para os prejuízos econômicos, com perdas de R$ 8.919,00. Para minimizar as perdas econômicas é necessário agir nos pontos críticos de condenação, o principal ponto observado no estudo foi o descarte de fígado por migração larval.Palavras-chave: fígado, subprodutos, lesões, migração, larval, prejuízo financeiro ABSTRACTThis study aimed to measure the economic losses caused by the condemnation of swine organs in municipal slaughterhouses under the supervision of the municipal inspection system (MIS) from the city of Santa Maria-RS during 12 months in a row. The study was conducted by collecting data from slaughterhouses in Santa Maria, Rio Grande do Sul, Brazil, in MIS. The registered data took into account the number of animals slaughtered, number of condemned organs and major lesions that led to condemnation from October 2010 to September 2011. During the evaluation period, 6,193 animals were slaughtered. It was found that 5,511 organs were condemned, mostly because of aspiration of blood (n = 1,231), larval migration in liver (n = 991), and renal cyst (n = 807). The survey revealed that R$ 11,955.66 is wasted annually in condemnation of organs. It is noteworthy that the main injury that contributed to the economic damage was larval migration in liver, which discard amount reached R$ 8,919.00. In order to reduce economic losses, it is necessary to do something against the critical points of condemnation, in which the main one observed in the study was the disposal of liver caused by larval migration.

Intestinal parasites are closely related to basic sanitary conditions, socioeconomic status, level of education, age and hygiene habits of the population; it is a serious Brazilian public health problem. This study aims to identify the prevalence of intestinal parasites in two municipalities of Zona da Mata, State of Minas Gerais, Brazil. We analyzed the samples using spontaneous sedimentation technique. In Viçosa, collecting data from hygienic and sanitary characteristics was possible by applying a structured questionnaire. The diagnosis revealed 11.2 % intestinal parasites in urban areas and 27.7% in rural areas. In Muriaé, the prevalence of intestinal parasites was 13.85% in urban areas. The majority of parasites found in Viçosa were Ascaris lumbricoides, Ancylostoma duodenale, Entamoeba coli and E. histolytica. Furthermore, in Muriaé we found Strongyloides stercoralis, Ascaris lumbricoides, Ancylostoma sp, Taenia sp, Hymenolepis nana, Enterobius vermicularis, Giardia lamblia, Endolimax nana, Entamoeba coli and E. histolytica. These parasites may indicate principally instability in the socio-economic conditions, serving as an important warning for local public health. In both areas, enteroparasitosis is high and it is of great importance to initiate sanitary measures to reduce them.
