O ensino do teatro, na escola e na comunidade, reflete as formas teatrais contemporâneas ao mesmo tempo em que responde aos avanços das teorias da educação.

Processos que aliam dramaturgia e jogo são numerosos e consideráveis dentro do panorama teatral de nossos tempos.

Dentro dos estudos do teatro chileno do Século XX, são facilmente distinguíveis algumas etapas nas quais, tanto por motivos artísticos como de outra índole (políticos, sociais, econômicos, etc.), se manifestaram alguns fenômenos de interesse.

O Brasil viveu, nas últimas décadas, transformações estruturais que alteraram profundamente seu perfil, em movimentos que dificilmente podem ser apreendidos através de sínteses.

The purpose of the research was to evaluate the acaricide and preventive efficacy of association abamectina 0.6% and fluazuron 3.0% in control of Rhipicephalus microplus in artificial infestations cattle. Were selected 12 cattle, that were kept stabled, crossbreeds Gir x Dutch, males, composing six animals per group. The control group animals received no treatment, while animals in the treated group received the formulation within the association in a single dose of 600 mcg of abamectin and 3 mg of fluazuron per Kg of body weight by route “pour-on”. The infestations on the control and treated groups were performed with 2500 larvae of Rhipicephalus microplus, in days -23, -21, -19, -17, -15, -13, -11, -9, -7, -5, -3, -2, -1and the collecting of engorged females it was performed in days -3 to +91, daily. To evaluation the preventive efficacy, the infestations continued in days +7, +14, +21,+28, +35, +42, +49, +56, +63, +70 and the collecting of engorged females followed daily until day +94. The efficacy against reinfestation was calculated on days +7, +14, +21, +28, +35, +42 +49, +56, +63 and +70. Statistical analysis between the average engorged females recovered between the groups control and treated showed that there was a significant difference (p≤0,05) for all subsequent time taken to treatment. The tested product showed acaricide effectiveness results of 0,00%; 6,81%; 62,64%; 85,11%; 98,38%; 97,38%; 96,84%; 97,63%; 98,14%; 97,32%; 97,54%; 98,11%; 99,22%; 97,93%; 98,13%; 96,78%; 96,17%; 99,05%; 98,57%; 98,59%; 97,23%; 96,10%; 99,31% respectively for the experimental days +1, +2, +3, +4, +5, +6, +7, +8, +9, +10, +11, +12, +13, +14, +15, +16, +17, +18, +19, +20, +21, +22, +23 for treated group. The mean of the efficacy over the 23 days after treatment was 97,8%. The preventive effectiveness results of 98,12%; 98,68%; 98,36%; 97,88%; 96,76%; 96,45%; 96,84%; 97,03%; 95,36% and 87,07% respectively for the experimental days +7, +14, +21, +28, +35, +42, +49, +56, +63, +70. The association abamectin 0.6% with fluazuron 3.0% was effective against reinfestation by larvae of R. microplus until day 60 after treatment.

Listeria monocytogenes is the pathogen responsible for listeriosis foodborne outbreaks, which is a serious disease for animals and humans, mainly elderly, children and pregnant women. Listeriosis can progress to encephalitis, meningitis and septicemia, and cause miscarriage, foetal death or neonatal infection.  The aim of the current study was to estimate the occurrence of L. monocytogenes in sausages produced by Brazilian companies registered at the Federal Inspection Service (SIF) and discuss issues related to possible contamination. Samples were collected by the official service from companies throughout Brazil. Analyses were performed in official laboratories of the National Agricultural Laboratories Network (LANAGRO),  accredited by ISO 17025. During the study period, 98 samples of sausages were analyzed and L. monocytogenes was detected in 8.16% of the samples (8/98). Six sausage companies were found positive for L. monocytogenes, where cross-contamination occurred after heat treatment and prior to product packaging,  favouring the presence of this pathogen. Given that sausage is a cooked meat product that may or may not be heated prior to consumption, and is appreciated mainly by children, this, therefore, poses a risk to consumers. This result highlights that it is essential to intensify compliance with good manufacturing practices and to adopt risk mitigation measures to avoid this pathogen.

  Seroprevalence of Flavivirus in horses in Chaco province, Argentina. Circulation during 2013-2014. Griselda Inés Oria 1,2, Lorena Ivana Spinsanti3, Verónica Laura Pirota1,4, María Florencia Martínez3, Ornela Sofía Stechina1,5, Eduardo Etchepare 6,7, Marta Silvia Contigiani3 and Marina Stein 1,5. Flaviviruses are responsible for several emerging mosquito-borne diseases in Argentina and in the Americas. Some of these diseases are zoonosis and were detected in recent years: West Nile virus (WNV) and Saint Louis encephalitis virus (SLEV) among them. WNV originated in Africa was detected for the first time in America in 1999 and it was first isolated from diseased and dead horses in 2006 in Argentina. Neutralizing antibodies from wild birds, humans and horses have been also detected in later years. SLEV re-emerged as a human pathogen in Argentina with the first epidemic in 2005. During this outbreak, viral strains were isolated from Culex mosquitoes and several studies have detected neutralizing antibodies from birds, human and horses, in the last ten years.The aim of this work is to provide information on the activity of the Flavivirus SLEV and WNV, identifying the infection in horses in three localities of the province of Chaco. From May 2013 to May 2014, serological surveys from 68 asymptomatic horses were conducted.  Antibodies against SLEV (25 %) and WNV (8.82%) were detected. This is the first report of WNV circulation in equines from Chaco province and circulation of both viruses during the study period was demonstrated.   

This study aimed to verify the effect of “marcha” training on clinical, hematological and biochemical variables in Mangalarga Marchador horses. Twelve Margalarga Marchador horses were used, six females and six males. Each animal was submitted to gait training lasting 40 minutes on hard ground. These animals were already conditioned to the proposed training. The animals were assessed before exercise (M0) and immediately after its ending (M1). Was realized physical examination and collected blood samples by jugular venipuncture to obtain blood, plasma and serum for hematological and biochemistry profiles. The “marcha” training caused changes in values of all clinical and laboratory variables evaluated. At the physical examination showed increases in cardiac and respiratory rates, as well as in rectal temperature. An increase was observed in erythrocyte, hemoglobin, hematocrit and leukocyte values. Electrolytes such as sodium, potassium, chloride, magnesium and ionic calcium showed a decrease in their plasma concentration.  An increase in strong ion difference (SID) was observed due to the decrease of the chloride concentration causing a discreet metabolic alkalosis. There was an increase in the plasma concentrations of Lactate, glucose, CPK, total proteins and fibrinogen. As conclusion, the “marcha” causes small changes in the clinical, hematological and biochemical profiles in horses previously conditioned to this exercise.

The objective of this study was to evaluate the biological parameters of Rhipicephalus microplus engorged females exposed to the arthropod growth regulator fluazuron. A commercial formulation based on fluazuron (Acatak®, Novartis) was administered topically to stabled cattle artificially infested with R. microplus larvae. The infestations occurred on four alternate days (days -21, -17, -13 and -6) taking as day 0 (zero) the day of treatment with a single dose of fluazuron for the treated group. Fifteen engorged females from each group were collected from the floor of the stalls at the end of the engorgement period (21 days) on pre-established days: before (day 0) and after treatment (days 4, 8 and 15), respectively. After cleaning and preparation of the engorged females in the laboratory, the following biological parameters were analyzed: weight of the engorged female, weight of the female after laying (spent female), laying period, weight of the posture, egg production index, reproductive efficiency index, hatching percentage, and nutritional index. The average weight of engorged females showed a significant reduction on all days after treatment in the exposed group. Aside from the weight after laying, all other biological parameters showed a significant reduction on the eighth post-treatment day due to exposure to fluazuron. Knowledge of the effects of an active principle on biological parameters in a population of ticks is essential for appropriate implementation of integrated management practices for parasite control.

The purpose of this study was to monitor improvements in the hygiene and sanitation conditions, and milk safety after application of Good Manufacturing Practices (GMP) to milking. A total of 106 farms were assessed in four stages of six months in the regions named agreste, dairy region, mid-backlands and high backlands of Alagoas. Two activities were executed in the project: monitoring of milk quality and safety; and application of GMP to pre-milking and milking processes. Milk samples underwent determination of Somatic Cell Count (SCC), Total Bacterial Count (TBC) and composition. The results correspond to milk components, determination of mammary health indicative parameters - SCC and milking hygiene - TBC. Regarding SCC, 73% of producers complied with the standards established by normative instruction IN 62 as of 2017. Regarding TBC, the use of GMP increased from 46.75% to 59.87% the average of all assessed properties that complied with the established standards. Less than 4% of the properties presented one million or higher TBC/mL of milk. Results of SCC after application of GMP remained basically the same. Regarding TBC, rate changes deriving from the application of GMP were significant.
