Abstract: The most acceptable criteria for diagnosing bovine intramammary infections include results of bacteriological culture and measures inflammation. Therefore, information on the diagnostic characteristics procedures used to identify infected quarters is required. Thus, this study was designed evaluate a set classify infectious status an udder at quarter (single duplicate milk samples) cow (composite sample) levels, compare with somatic cell counts (SCCs) samples. Here, SCC thresholds...
We examined whether distinct staphylococcal and mammaliicoccal species strains trigger B- T-lymphocyte proliferation interleukin (IL)-17A interferon (IFN)-γ production by peripheral blood mononuclear cells in nulliparous, primiparous, multiparous dairy cows. Flow cytometry was used to measure lymphocyte with the Ki67 antibody, specific monoclonal antibodies were identify CD3, CD4, CD8 T CD21 B populations. The supernatant of cell culture IL-17A IFN-γ production. Two distinct, inactivated...
The objective of the present study was to evaluate different methods for indirectly diagnosing mastitis during postpartum period. These were: automatic and microscopic somatic cell counting (SCC), California Mastitis Test (CMT) Somaticell®. A total 538 milk samples from 34 cows were used. collected at six times: day parturition (M1) 3 (M2), 7 (M3), 15 (M4), 21 (M5) 30 (M6) days after parturition. Automatic SCC, CMT Somaticell® all able detect immediate period (up postpartum). However, higher...
An experiment was conducted to evaluate the effects of inorganic trace minerals (TM) and reduced levels TM by using proteinate forms Co, Zn, Mn, Cu, Se-yeast in diets transition cows on performance, concentrations colostrum, plasma, liver, blood metabolites, antioxidant status, peripheral neutrophil activity, oocyte quality. Thirty-two Holstein (22 multiparous 10 primiparous cows) were enrolled this study from 30 d before expected calving date 56 DIM. Cows blocked according body condition...
This study has detected BPV-1 DNA sequences in wart, blood and plasma samples collected from animals affected by papillomatosis, suggesting viral presence inside the cell. We sellected an animal which we could detect blood, placenta amniotic liquid her offspring presented sample immediately after birth. These results show a possible vertical transmission of BPV-1.
The immune system of newborn calves is immature and must mature gradually. Understanding how this immunity established may define different profiles. Twelve healthy were monitored during 8 time periods to assess the innate first 90d. Blood samples collected, blood phagocytes, identified by expression CD14 CH138 surface molecules, evaluated for phagocytic functionality (Staphylococcus aureus Escherichia coli stained with propidium iodide) intracellular production reactive oxygen species...
RESUMO O objetivo do presente trabalho foi avaliar diferentes indicadores inflamatórios no diagnóstico da mamite em ovinos raça Santa Inês. Após a realização exame físico das mamas e prova de fundo escuro, foram coletadas analisadas 390 amostras leite, sendo as metades mamárias divididas acordo com o bacteriológico resultando 290 negativas ambos os exames, 90 à escuro positivas na cultura bacteriológica, 5 ao 3 testes. Nestas realizadas contagem automática células somáticas (CCS), California...
Streptococcus dysgalactiae is a bacterium that accounts for notable proportion of both clinical and subclinical intramammary infections (IMIs). Thus, the present study explores function milk neutrophils lymphocyte profile in mammary glands naturally infected with . Here, we used 32 culture-negative control quarters from eight clinically healthy dairy cows low somatic cell counts 13 S. -infected six cows. Using flow cytometry, evaluated percentage monocytes/macrophages neutrophils, expression...
In the present study, we aimed to determine antimicrobial resistance and molecular typing of Staphylococcus aureus recovered from transient persistent intramammary infections nares/muzzles in dairy cows. We investigated 189 S. strains using a broad susceptibility profile. Furthermore, 107 isolates were strain-typed staphylococcal protein-A (spa) typing. A large proportion exhibited multidrug antimicrobials, including critically important although no methicillin-resistant found. Our study did...
This study analyzed the influence of number milkings, births, and udder quarter in immunoglobulin (Ig) concentration colostrum healthy Holstein cows. It was collected two samples by manual milking, getting first jets to completion bacteriological examination levels radial immunodiffusion test agar gel. Positive for were excluded from this investigation. Medians immunoglobulin's G, A M before second milking respectively 9,200 6,400mg/dL (p=0.0029); 400 200mg/dL (p=0.0018); 800 400mg/dL...
Avaliou-se a celularidade do colostro de 53 vacas da raça Holandesa, utilizando-se 171 amostras, colhidas após primeira e segunda ordenha pós-parto. Para análise citológica quantitativa qualitativa, foram utilizadas as técnicas microscopia direta citocentrifugação. O total leucócitos obtido por contagem microscópica foi 0,878x10(6) 1,260x10(6), antes ordenha, respectivamente, os valores mediana dos fagócitos obtidos 0,657 0,828x10(6) mononucleares, 0,178 0,392x10(6) polimorfonucleares...
The aim of this study was to investigate the relationship between clinical findings and bacterial isolation in milk samples meat-producing ewes. conducted 17 commercial flocks 550 udder halves from suckling Santa Ines Initially, examination mammary glands teats performed by visual inspection palpation halves; then a scoring system devised for all findings. After that, strip cup test California mastitis (CMT) were performed. Then, somatic cell counts (SCCs) bacteriological analyses collected....
