Rapid, sensitive and specific methods are necessary to confirm the diagnosis of outbreaks of avian infectious bronchitis virus (IBV) infection. The amplification of IBV genome by reverse transcription followed by polymerase chain reaction (RT-PCR) has been one of the most used methods for the detection of this virus in clinical samples. To reduce the time and the number of steps in the molecular diagnosis of IBV, we developed a sensitive and rapid detection method based on viral capture by a lectin (Concanavalin A—Con A) in the microplate wells, followed by RT-PCR to amplify the S1 gene. The detection limit of IBV was 103 EID50/ml for the amplification of 5’part of the S1 gene, and 104 EID50/ml for the amplification of full S1 gene. This technique was specific for IBV detection, and no amplified products were detected for other avian viral pathogens (bursal infectious disease virus, avian metapneumovirus and Newcastle disease virus). The MLC-RT-PCR was as sensitive as conventional RT-PCR, and virus isolation method for the detection of IBV in tissue samples collected from experimentally infected birds. The MLC-RT-PCR technique demonstrated a great potential for the rapid and specific diagnosis of IBV.

Differential IL10 mRNA Profiles Associated to <i>Babesia bovis</i>and <i>B. bigemina</i>Infection Levels in Persistently Infected Animals

Open Journal of Veterinary Medicine 2019年第11期9卷 161-169页

This work aimed to find quantitative phenotypic traits that can be used to discriminate the levels of resistance/susceptibility to B. bovis and B. bigemina in two groups of cattle presenting the highest (H) or lowest (L) infection levels and Rhipicephalus microplus ticks count. The animals were selected from a previous study of 50 Canchim (5/8 Charolais/zebu) heifers raised in an endemic area for these parasites. These animals were evaluated regarding their TNFα, IL10, IFN-γ, IL12 and iNOS mRNA levels. No differences were found between these groups regarding TNFα, IFN-γ, IL12β or iNOS transcripts. However, the IL10 transcripts were significantly higher in the H group compared to the L group. Moreover, significant correlation coefficients were observed between B. bovis loads and both IL10 and IFN-γ transcripts, while no correlations were found for B. bigemina loads and all tested immune-related transcripts, suggesting that differential IL10 mRNA profiles were closely associated to B. bovis loads. Our results have contributed to a better understanding of the immune responses against Babesia infection, as we demonstrated that the IL10 cytokine levels might also influence or be influenced by parasitemia levels in persistently infected animals.
