Caprine lentivirus in sheep milk and semen. Repositório Alice
LIMA, C. C. V.; AYRES, M. C. C.; PINHEIRO, R. R.; COSTA, J. N.; ANDRIOLI , A.; SOUZA, T. S.; AZEVEDO, D. A. A.; SANTOS, V. W. S.; ARAÚJO, J. F.; SOUSA, A. L. M.; PEIXOTO, R. M.; DAMASCENO, E. M.; COSTA NETO, A. O..
Abstract: With the objective of detecting the presence of caprine lentivirus (CLV) in ewe milk and in ram semen, ten matrixes and four reproducers experimentally infected with CLV were used. Samples of ewe milk were collected during the four months of lactation, five collections per animal, totaling 50 samples. Regarding the rams, eight semen collections were made per animal, during one year of experimentation, totaling 32 samples. The milk and semen samples were submitted to DNA extraction and the nested polymerase chain reaction test (nPCR) to detect CLV proviral DNA. Eight (16%) of the milk samples were positive in nPCR originating from two ewes. Only one (3.12%) semen sample was positive. The amplification products were sequenced, and were confirmed to...

Infección cruzada de especies de Colletotrichum en frutos tropicales en postcosecha. Colegio de Postgraduados
Aguilar Pérez, Luis Alfonso.
El género Colletotrichum es considerado uno de los principales hongos patógenos de plantas, este hongo se encuentra distribuido a escala mundial y afecta a diferentes cultivos tanto en pre y postcosecha. En el presente trabajo se aislaron e identificaron morfológicamente y molecularmente ocho aislamientos de Colletotrichum sp, de banano, papaya, carambolo, chile manzano, aguacate, mango ataulfo y mango manila, estos se inocularon sobre cada uno de los frutos para evaluar el fenómeno de infección cruzada. Se midió diariamente el diámetro de la lesión por siete días. Los resultados mostraron que algunos aislamientos de C. gloeosporioides son más agresivos cuando se inoculan sobre su hospedero original, sin embargo ocasionan daños en menor grado en hospederos...

Interspecific transmission of small ruminant lentiviruses from goats to sheep. Repositório Alice
SOUZA, T. S. de; PINHEIRO, R. R.; COSTA, J. N.; LIMA, C. C. V. de; ANDRIOLI, A.; AZEVEDO, D.A. A. de; ARAÚJO, J. F.; SOUSA, A. L. M. de; PINHEIRO, D. N. S.; FERNANDES, F. M. C.; COSTA NETO, A. O..
Abstrract: This study was conducted in order to evaluate the transmission of caprine lentivirus to sheep using different experimental groups. The first one (colostrum group) was formed by nine lambs receiving colostrum from goats positive for small ruminant lentiviruses (SRLV). The second group (milk group) was established by nine lambs that received milk of these goats. Third was a control group, consisting of lambs that suckled colostrum and milk of negative mothers. Another experimental group (contact group) was formed by eight adult sheep, confined with two naturally infected goats. The groups were monitored by immunoblotting (IB), enzyme-linked immunosorbent assay (ELISA), agar gel immunodiffusion (AGID) and nested polymerase chain reaction (nPCR)....

Sheep infection by caprine lentivirus. Repositório Alice
SOUZA, T. S. de; PINHEIRO, R. R.; LIMA, C. C. V. de; BRITO, R. L. L. de; AZEVEDO, D. A. A. de; DIAS, R. P.; SANTOS, V. W. S. dos; ANDRIOLI, A.; COSTA, J. N..
Abstract: The objective of this study was to demonstrate iatrogenic transmission of small ruminant lentivirus (SRLV) from goats to sheep and horizontal transmission between sheep. The study was conducted on a farm with separate goat and sheep rearing, and animals were monitored for lentivirus occurrence by clinical examination and testing by immunoblotting (IB), agar gel immunodiffusion (AGID), and nested polymerase chain reaction (nPCR). Positive results had not been observed in the sheep flock until this study. Conversely, virus positive dairy goats were known. For this reason, the farm performed the caprine arthritis-encephalitis (CAE) control program. The study was designed with a sheep group that presented positive animals for SRLV by nPCR. It was...

The ant fauna of hospitals: advancements in public health and research priorities in Brazil Rev. Bras. entomol.
Castro,Mariana Monteiro de; Prezoto,Helba Helena Santos; Fernandes,Elisa Furtado; Bueno,Odair Correa; Prezoto,Fábio.
Ants inhabit several types of natural and urban habitats, where they successfully nest. In urban environments, the hospitals should be considered priority for studies, as ants pose risks to human health due to their pathogen carrying potential. We aimed at surveying the literature about studies on ants in hospital settings in Brazil in the past 20 years. We found 40 papers in 22 journals, the first one published in 1993. Among them, 26 papers assessed pathogenic microorganisms on ants. We recorded 59 ant species, being Tapinoma melanocephalumthe most common. The Minas Gerais and São Paulo states had the largest number of published papers. Mato Grosso do Sul and Rio Grande do Sul showed the highest number of species. Exotic ant species were recorded in all...

Transmissão interespécies de lentivírus de caprinos para ovinos. Repositório Alice
SOUZA, T. S. de..
Resumo: A artrite-encefalite caprina (CAE) e a maedi-visna (MV) acometem caprinos e ovinos, respectivamente. Durante anos, os agentes etiológicos dessas enfermidades foram considerados como específicos a cada espécie animal. Entretanto, análises filogenéticas têm demonstrado a heterogeneidade desse vírus, reunindo diferentes genótipos e subtipos em um grupo denominado de lentivírus de pequenos ruminantes (LVPR). Sendo assim, o principal objetivo deste trabalho foi avaliar a transmissão interespecífica do lentivírus de caprinos para ovinos, a partir de quatro grupos experimentais. O primeiro (grupo colostro) foi formado por nove cordeiros que receberam colostro de cabras positivas para LVPR. O segundo (grupo leite) foi estabelecido por nove cordeiros que...
