The karyotypes of Biomphalaria tenagophila collected from Rio de Janeiro, Brazil were studied using the air-drying method. Somatic cells of this species had 2n=36. The 18 chromosome pairs were identified and classified into 3 groups. The diploid cell has 7 pairs of metacentric, 8 pairs of submetacentric, and 3 pairs of subtelocentric chromosomes. Observed chromosomes ranged from 2.4 to 6.4 microm, and the total length was 122.3 microm. This is the first report on the chromosome of B. tenagophila.

Investigations of Enterobius sp. infection in prehistory have produced a body of data that can be used to evaluate the geographic distribution of infection through time in the Americas. Regional variations in prevalence are evident. In North America, 119 pinworm positive samples were found in 1,112 samples from 28 sites with a prevalence of 10.7%. Almost all of the positive samples came from agricultural sites. From Brazil, 0 pinworm positive samples were found in 325 samples from 7 sites. For the Andes region, 22 pinworm positive samples were found in 411 samples from 26 sites for a prevalence of 5.3%. Detailed analyses of these data defined several trends. First, preagricultural sites less frequently show evidence of infection compared to agricultural populations. This is especially clear in the data from North America, but is also evident in the data from South America. Second, there is an apparent relationship between the commonality of pinworms in coprolites and the manner of constructing villages. These analyses show that ancient parasitism has substantial value in documenting the range of human behaviors that influence parasitic infections.

Endometriosis is common estrogen-related gynecological diseases related to interactions of dietary, genetic causes, social and environmental factors. The high prevalence approaches 5-15% in premenopausal women and 30% in infertile women, and it is unusual to occur after the onset of menopause. In this review, the gene polymorphisms of estrogen receptor (ER) alpha and betare-lated to the risks of endometriosis were investigated through statistical analysis by using the gene polymorphism for the risks of the disease examined trends. The polymorphism of ERalpha-PvuII in Europe tends to increase the risk of endometriosis and, ERalpha-XbaI polymorphisms in both Asia and Europe have a slightly increased risk of endometriosis. In the case of ERbeta-RsaI, the risk of endometriosis increases in Brazil, while the polymorphism of ERbeta-AluI reduces the disease risks in Asia. Polymorphism studies on ER associated with the risk of endometriosis in Asia and Europe showed that those polymorphisms may be used to predict the high or low risks of endometriosis, and potentially used for prevention, therapy or prognosis of endometriosis. Further studies on interacting with more related genes and environmental factors may provide a better understanding of associations between estrogen receptor gene polymorphisms and endometriosis.

Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the transmission ecology of the site.

The review article presents some of the history of how paleoparasitology started in Brazil, making highlight the great responsible Dr. Luiz Fernando Ferreira and Dr. Adauto Araújo, the trajectory of paleoparasitology in Brazil since 1978 and its performance in science to the present day. In sequence, it is made a presentation of parasitological findings on human remains found in archaeological sites in South America, highlighting Brazil, Argentina, Chile, and Peru, where major discoveries have occurred. Many of the parasites found in archaeological material and mentioned in this review went out of Africa with the peopling of Europe and from there they dispersed around the world, where climatic conditions allow the transmission. However, humans have acquired other parasites of animals, since humans invaded new habitats or creating new habits adopting new technologies, thus expanding its range of influence on the environment. Thus, this review article is finalized with information that explain the importance of these findings in the interaction between parasites, human host, and ambient.

The cadmium concentrations in mineral mixtures used in beef cattle feed in the states of Sao Paulo and Parana, Brazil was measured. The cadmium concentration was determined by inductively coupled plasma atomic emission spectrometry. Of the 36 analyzed samples, 35 had values > 0.5 ppm (range 0.5 to 11.2 ppm), which is the maximum concentration recommended [4, 18]. These findings show the necessity for careful industrial monitoring, as some mineral mixtures contain sufficient cadmium to cause toxicity in animals.

Intoxifications caused by toxic honey were occurred recently in Korea. Honey poisoning is known to be induced by grayanotoxins, that appear in flowers of different species of Rhododendron. These toxic compounds cause depolarization of membranes that contain fast Na channel by increasing in Na permeability. After ingestion of toxic honey patients may present with neurological, cardiovascular, gastrointestinal sign and symptoms. Two cases of honey poisoning are described here. Both patients experienced syncope and severe arterial hypotension after ingestion of honey which was brought from Nepal and Brazil. Conservative treatement was fully successful in both patients within 24 hours. We report the first case of honey poisoning in Korea.

Zika virus (ZIKV) is a vector-borne flavivirus. It was initially identified in Uganda in 1947, and the first human infection was reported in Nigeria in 1953. Since 2015, ZIKV has been spreading rapidly in Brazil and the Americas. Given its general symptoms, ZIKV is considered to be a mild, febrile illness, although it is associated with severe neurologic complications. On February 1, 2016, the World Health Organization (WHO) declared a Public Health Emergency of International Concern (PHEIC). We conducted a review of the literature on the epidemiology and transmission, clinical manifestations, and diagnosis of ZIKV. Additionally, we introduce original literature on the current ZIKV outbreak in this review.
