Side effects of antimalarial drug can overlap with malaria symptoms. We evaluated 50 patients with vivax malaria in Mâncio Lima, Acre, treated with chloroquine and primaquine. Patients were evaluated for the presence of 21 symptoms before and after treatment and for reported side effects of these drugs after treatment was started. The most frequent symptoms before medication were headache, fever, chills, sweating, arthralgia, back pain, and weakness, which were present in between 40% and 76% of respondents. The treatment reduced the occurrence of these symptoms and reduced the lack of appetite, but gastrointestinal symptoms and choluria increased in frequency. There were no reports of pale stools before medication, but 12% reported the occurrence of this symptom after treatment started. Other symptoms such as blurred vision (54%), pruritus (22%), paresthesia (6%), insomnia (46%), and “stings” into the skin (22%) were reported after chloroquine was taken. The antimalarial drugs used to treat P. vivax malaria reduce much of the systemic and algic symptoms but cause mainly gastrointestinal side effects that may lead to lack of adherence to drug treatment. It is important to guide the patient for the appearance and the transience of such side effects in order to avoid abandoning treatment.

Leptospirosis in native mixed-breed sheep slaughtered in a semiarid region of Brazil.

The adaptation of the animals, either temperate or tropical climate, is mainly related to physiology and its adaptation to the environment. When subjected to different air temperature and air humidity from the usual, these animals found in heat stress difficulty reproduction and production. The endocrine system is one of those responsible for controlling the stress response, and rapid and appropriate growth is one of the elements of greatest economic importance toward meat production, and more producers want to improve, to accelerate the production rate and decreasing production costs. Thus, the aim of this review was to evaluate, through research papers found in the literature, the influence of heat stress on the hormones of growth and reproduction in ruminants. It was observed that even in studies that do not consider the productive performance of the animals, the influence of these parameters is significant in the ambience and the degree of adaptation of the same. However, more research should be conducted in order to evaluate the production of animals of different species under the conditions of different regions, as well as search for alternatives to achieve the best animal production levels, either by finding the best way of introducing exotic breeds, or the possibility of bringing more comfort to the animals in their various productive and reproductive stages.

The aim of this survey was to determine the frequency of anti-Leptospira spp. antibodies in goats and sheep slaughtered in different slaughterhouses in the State of Paraiba, in the semi-arid region of Northeastern Brazil. Blood samples were collected from 500 goats and 500 sheep randomly selected. To verify the presence of anti-Leptospira spp. antibodies the microscopic agglutination test (MAT), using 24 serovars as antigens, was used. From the 1,000 animals analyzed, 82 (8.2%; 95% CI = 7.0%-10.5%) were sero-reactive being 26/500 (5.2%; 95% CI = 3.5%-7.5%) in goats and 56/500 (11.2%; 95% CI = 8.7%-14.2%) in sheep. The most frequent serovars were Hardjobovis (14.6%) and Autumnalis (13.4%). In goats, the most frequent serovar was the Hardjobovis, and in sheep the Ballum, with frequencies of 19.2% and 17.9%, respectively. There was a significant difference in the frequency of positive animals among slaughterhouses, both for goats (p = 0.035) and for sheep (p = 0.004), with the county of Alhandra presenting the highest frequency of seropositive animals for both species. It is concluded that sheep and goats from the semiarid region of the Northeastern Brazil may have become adapted to the serovars Hardjobovis e Autumnalis, as well as wild rodents may be involved in the transmission of the disease. It is possible that the climatic conditions influenced in the transmissibility of the leptospirosis, especially in the Mata Paraibana mesoregion, however it was not considered as being sufficient to justify the low frequency of seropositive animals. In this way, it is possible to suggest the hypothesis that the rusticity of the small ruminants in the studied region contributed to the low sero-reactivity verified. Key words: Adaptability. Goats.

ResumoO objetivo deste estudo foi determinar a frequência de anticorpos anti-Leptospira spp. em caprinos e ovinos abatidos em diferentes matadouros no Estado da Paraíba, região semiárida do Nordeste brasileiro. Foi coletado sangue de 500 caprinos e 500 ovinos aleatoriamente selecionados. Para verificar a presença de anticorpos anti-Leptospira spp. empregou-se o teste soroaglutinação microscópica (SAM), utilizando-se 24 sorovares como antígenos. Dos 1.000 animais analisados 82 (8,2%; IC 95%= 7,0%-10,5%) foram sororreagentes, sendo 26/500 (5,2%; IC 95% =3,5%-7,5%) em caprinos e 56/500 (11,2%; IC 95% 8,7%-14,2%) em ovinos. Os sorovares mais frequentes foram Hardjobovis (14,6%) e Autumnalis (13,4%). Na espécie caprina, o sorovar mais frequente foi o Hardjobovis, e na espécie ovina o Ballum, com frequências de 19,2% e 17,9%, respectivamente. Houve diferença significativa na frequência de positivos entre os matadouros, tanto para caprinos (p = 0,035) quanto para ovinos (p = 0,004), com o município de Alhandra apresentando a maior frequência de soropositivos para ambas as espécies. Concluiu-se que ovinos e caprinos da região semiárida do Nordeste podem estar adaptados aos sorovares Hardjobovis e Autumnalis, bem como roedores silvestres estarem envolv...
