Microbiological analysis of bacterial plaque of periodontal disease on dogs and effects of antibioticotherapy on it

Objetivou-se determinar a microbiota da placa bacteriana subgengival de cães com doença periodontal (DP) e estabelecer o efeito da antibioticoterapia. Avaliaram-se 20 cães com graus variados de DP e coletaram-se amostras da placa bacteriana subgengival antes e após antibioticoterapia. Preconizou-se antibioticoterapia distinta em dois grupos, com 10 animais cada: clindamicina (G1) e metronidazol + espiramicina (G2). Observou-se crescimento bacteriano subgengival na maioria dos cães com DP e correlação entre a severidade da DP e a idade dos animais. Houve redução significativa no crescimento bacteriano após a antibioticoterapia e o antibiograma demonstrou maior sensibilidade à clindamicina, seguido da espiramicina; todos os microrganismos foram resistentes ao metronidazol. ___________________________________________________________________________________________________ ABSTRACTThe objective was to determine microbiote of the subgingival bacterial plaque of dogs with periodontal disease (PD) and establish the effect of antibioticotherapy on its reduction. Twenty dogs with varied stages of PD were evaluated and samples of their subgingival bacterial plaque were collected. Distinct antibiotic protocols were used in two groups with ten animals each: clindamycin (G1) and metronidazole + espiramycin (G2). New subgingival samples were collected 15 days after antibiotic therapy started. There were observed subgingival bacterial culture on most dogs with PD and correlation between severity of PD and age. There was reduction of bacterial growth in 20% of the samples after treatment and antibiogram showed higher sensibility to clindamycin, followed by espiramycin - all microorganisms were resistant to metronidazole

Dynamics and determinants of SARS-CoV-2 RT-PCR testing on symptomatic individuals attending healthcare centers during 2020 in Bahia, Brazil

RT-PCR testing data provides opportunities to explore regional and individual determinants of test positivity and surveillance infrastructure. Using Generalized Additive Models, we explored 222,515 tests of a random sample of individuals with COVID-19 compatible symptoms in the Brazilian state of Bahia during 2020. We found that age and male gender were the most significant determinants of test positivity. There was evidence of an unequal impact among socio-demographic strata, with higher positivity among those living in areas with low education levels during the first epidemic wave, followed by those living in areas with higher education levels in the second wave. Our estimated probability of testing positive after symptom onset corroborates previous reports that the probability decreases with time, more than halving by about two weeks and converging to zero by three weeks. Test positivity rates generally followed state-level reported cases, and while a single laboratory performed ~90% of tests covering ~99% of the state's area, test turn-around time generally remained below four days. This testing effort is a testimony to the Bahian surveillance capacity during public health emergencies, as previously witnessed during the recent Zika and Yellow Fever outbreaks

Effect of grazing alternate and simultaneous on the parasite infection and its consequences on hematological parameters of sheep and cattle

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Agronomia e Medicina Veterinária, 2010.Devido à grande importância da infecção gastrointestinal na criação de ruminantes, especialmente em ovinos, a utilização de medicamentos anti-helmínticos é amplamente empregada pelos criadores. Esta prática, entretanto, apresenta elevados custos e tem resultado no surgimento de vermes resistentes aos princípios ativos disponíveis no mercado. Em atenção a este problema, pesquisadores de todo o mundo têm estudado formas de reduzir o grau de infecção parasitária sem a utilização exclusiva de medicação. Para tanto, têm-se dado enfoque para técnicas de manejo do pasto que ajudem na redução da população parasitária ambiental, e, consequentemente, na redução da carga parasitária dos animais. Diversos aspectos ambientais podem influenciar e favorecer a infestação parasitária das pastagens. Alguns deles, como o tipo e altura da forrageira utilizada, taxa de lotação e rotação de piquetes, podem ser manejados de forma racional com objetivo de reduzir a exposição dos animais aos vermes. _________________________________________________________________________________________ ABSTRACTDue to the great importance of gastrointestinal infection in the creation of ruminants, especially sheep, the use of anthelmintic drugs are widely used by farmers. This practice, however, has high costs and has resulted in the emergence of worms resistant to active ingredients available. In response to this problem, researchers around the world have been studying ways to reduce the degree of parasitic infection without the exclusive use of medication. For this, have given focus to pasture management techniques that help in decrease the environmental parasite population and consequently reducing the parasite load of animals. Several environmental aspects can influence and favor the parasitic infestation of pastures. Some, like the height and type of forage used, stocking rate and rotation of paddocks, can be managed in a rational way in order to reduce the exposure of animals to the worms

“Os homens que odiavam as mulheres”: relações de gênero em jogos internos de uma universidade pública

As relações de gênero estão presentes em diferentes espaços sociais e muitas vezes expressam posturas preconceituosas. Este texto pretende analisar a relação presente entre o gênero feminino e a cultura em um evento esportivo e cultural na cidade de Goiânia a partir de um regulamento sexista amplamente divulgado nas mídias regionais. Método: Foi feita uma análise documental com o “ranking” disponibilizado por mídias sociais e, nele foram analisados dezenove itens discriminados nos critérios de interesse relacional heterossexual durante os jogos realizados no evento de uma universidade pública do estado de Goiás, interior do Brasil. Resultados: Os dados demonstram um movimento na qual a relação de subalternidade de alguns grupos foi evidenciado, a virilidade masculina protagonizou o evento, de forma que se estabeleceram relações desiguais entre homens e mulheres, na qual os corpos femininos foram colocados sob extrema avaliação e constrangimento. Conclusão: A conclusão aponta para uma série de preconceitos quanto aos comportamentos sexistas, misóginos, heteronormativos e étnico-raciais

Dry matter intake, performance and carcass characteristics of hair sheep reared under different grazing systems

The aim of this study was to evaluate the effect of three different grazing systems: isolated, alternate and simultaneous, on feed intake, performance and carcass characteristics of sheep. About 5.2 ha area of Tanzania grass (Panicum maximun Jacq cultivate Tanzania) was divided into 13 paddocks. This area was used as a stocking rate of two animal units (AU) per ha for 7 days’ occupation and 21 days rest. A total number of 58 animals were used consisting of 12 heifers and 30 Santa Ines lambs with the addition of 16 adult ewes that were used to stabilize grazing pressure in the isolated system. The sheep were fed on 200 g per head per day of concentrate and cattle 2 kg per head per day. The parameters determined were the following: weekly weight (WW), total live weight gain (LWG) and mean daily weight gain (MDW). Also dry matter intake was estimated 84 days after the start of the experiment using external indicators (Purified and Enriched Lignin) in addition to carcass traits and composition which were also estimated. The result obtained for carcass composition revealed that the muscle:bone ratio and bone percentage were better in the alternate system. Moreover, the simultaneous and isolated systems showed higher lamb performance than the alternate system, while there was no effect on dry matter intake. Furthermore, there was no difference of the different systems on carcass traits and feed intake of sheep. Nevertheless, the simultaneous grazing system showed better sheep performance than the alternate grazing system

Seizures during pregnancy modify the development of hippocampal interneurons of the offspring

We investigated the effect of epileptic seizures during pregnancy on hippocampal expression of calcium-binding proteins in the offspring. Female Wistar rats were submitted to the pilocarpine model and mated during the chronic period. Seizure frequency was monitored over the entire pregnancy. Pups were perfused at postnatal days 6 and 13. and the brains processed for Nissl staining and immunohistochemistry for NeuN, calbindin, calretinin, and parvalbumin. Number of stained cells in the hippocampus was estimated through stereological methods. Our results showed a decrease in epileptic seizure frequency during pregnancy. No differences were observed in NeuN-positive. CR-positive cells, and Nissl-stained hippocampal neurons between the groups. However, there was a significant decrease in calbindin-positive cells (P=0.005) and a significant increase in parvalbumin-positive cells (P=0.02) in the experimental group when compared with the control group. These results suggest that seizures during pregnancy affect the development of specific hippocampal interneurons of the offspring. (C) 2010 Elsevier Inc.
