<title>Abstract</title> Background The World Health Organization recommends systematic active case finding for tuberculosis (TB) among high-risk population including incarcerated individuals; however, many prisons lack screening capacity. In this study, we aimed to evaluate the diagnostic performance of an ultra-portable digital chest radiography system paired with LunitTB, automated interpretation algorithm, detect TB disease. Methods We performed a test accuracy study using data collected...
S. aureus is one of the main agents nosocomial infection and sometimes difficult to treat with currently available active antimicrobials. To analyze prevalence methicillin-susceptible S.aureus (MSSA) methicillin-resistant (MRSA) as well MRSA antimicrobial susceptibility profile isolated in saliva health professionals at a large public education hospital. The project was approved by research ethics committee institution under study. Three samples from 340 were collected. analysis used...
Parasites can exert selection pressure on their hosts through effects survival, reproductive success, sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability. Consequently, hemoparasites have become the focus of recent avian studies. Infection varies significantly among taxa. Various factors might explain differences infection taxa, including habitat, climate, host density, presence vectors, life history immune defence....
Coelhos são susceptíveis à infecção pelo herpes-vírus bovino tipo 5 (BHV-5) e freqüentemente desenvolvem enfermidade neurológica aguda fatal após inoculação intranasal. A cinética da invasão do sistema nervoso central (SNC) de coelhos BHV-5 foi estudada através pesquisa vírus em secções SNC a diferentes intervalos pós-inoculação. Após intranasal, o inicialmente detectado no bulbo olfatório às 48h, seguido córtex 48/72h. Às 72/96h também gânglio trigêmeo, ponte cerebral. Dois experimentos...
This study evaluated the knowledge of a nursing team from public hospital in state São Paulo, Brazil concerning preventive measures recommended care delivered to patients colonized with Methicillin Resistant Staphylococcus Aureus (MRSA) and, through Health Beliefs Model, identified factors influencing adherence or non-adherence measures. A total 318 professionals different units participated study. According analysis, teams and perception MRSA susceptibility was limited, which indicates need...
This article describes the main aspects of bovine herpesvirus type-5 (BHV-5) neurologic infection and disease in rabbits, a candidate animal model for studying BHV-5 neuropathogenesis. Intranasal inoculation weanling rabbits with Brazilian isolate produced neurological death 78.8% (26/33) animals. Neurological signs started as early 5 days post-inoculation lasted from 10-12 hours up to several days. Most animals evolved moribund state or within 24 (69.2%) 48 (88.5%). was characterized by...
Avian hemosporidian parasites of the genera Haemoproteus, Plasmodium, and Leucocytozoon are transmitted by different dipteran vectors. In present work, we looked for presence these in 47 birds from 12 families, which were sampled migratory corridor Paso de Portachuelo, located at Henri Pittier National Park, Venezuela. The was evidenced amplification a region 471 bp their cytochrome b gene. This marker presents enough polymorphism to identify most mitochondrial lineages. Therefore, obtained...
O presente artigo relata a caracterização inicial de 19 amostras do vírus da Diarréia Viral Bovina (BVDV) isoladas no Brasil, com relação aspectos biológicos, antigênicos e moleculares. Onze foram fetos bovinos, seis obtidas sangue animais clinicamente saudáveis rebanhos problemas reprodutivos duas casos clínicos enfermidade gastrentérica. Os doença entérica afetaram jovens cursaram diarréia, às vezes sanguinolenta, erosões ulcerações na mucosa oronasal trato digestivo, eventualmente...
Infecção experimental de ovinos com o herpesvírus bovino tipo 5 (BHV-5) reproduziu vários aspectos da infecção pelo BHV-5 em bovinos. Inoculação intranasal foi seguida extensiva replicação viral na cavidade nasal, excreção e transmissão do vírus a outros animais, estabelecimento reati-vação latência, desenvolvimento meningoencefalite clínica um animal. Ovinos inoculados amostra brasileira EVI-88 apresentaram hipertermia transitória, hiperemia mucosa nasal corrimento seroso muco-purulento. Os...
Two different ELISAs were routinely performed in our laboratory to detect bovine trypanosomosis and anaplasmosis. The ELISA test for involved the adsorption of a soluble fraction parasites as antigen; and, anaplasmosis was with purified recombinant protein MSP5r adsorbed plate. With purpose assessing merit ABTS TMB, we compared absorbance obtained from positive negative control sera both assays. results obtained, suggest that TMB is more adequate antigens preferred when partially antigenic...
Venezuela has a remarkable presence of endemic birds from the Neotropical region. Therefore, study avian haemosporidian parasites (Plasmodium, Haemoproteus, Leucocytozoon) in should be priority task for conservation projects, as well understanding adaptive processes parasite-host-vector triad. The objective this mini-review is to rescue most relevant contributions these and potentialities derived them. greatest contribution reported so far comes series parasitological diagnoses carried out...
By amplifying and sequencing a mitochondrial DNA barcode (cytb), we screened the frequency of haemosporidian parasites (Haemoproteus, Plasmodium, Leucocytozoon) in 366 birds (23 species) from Margarita Coche islands, Venezuela. In (N = 24), none were infected, while 342) 13 individuals (3.8%). The these endemic bird subspecies was more than double non-endemic forms (endemics 7.3% vs 3.1%, N 342), but it not statistically significant. We found eight parasite lineages, four which are novel...
