This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...

ABSTRACT Background Bovine leukaemia virus (BLV) and Coxiella burnetii are important infectious pathogens of dairy cattle with potential implications for animal health, productivity and zoonotic transmission (in the case of C. burnetii). Because BLV may alter immune function, we hypothesize that infection with the virus could increase cattle ...

Is Italy one of the countries with the highest genetic diversity of bovine viral diarrhea virus?
Genetic typing of bovine viral diarrhea virus (BVDV) has distinguished BVDV-1 and BVDV-2 species and an emerging putative third species (HoBi-like virus), recently detected in southern Italy, representing the first report of cattle natural infection in ...

Bovine bacterial abortion caused by Escherichia coli infection
Abstract A 3‐year‐old, 500 kg Holstein cow aborted at 7 months of gestation. On histological evaluation of the fetal lungs, abundant neutrophils infiltrated the alveolar spaces, bronchi and bronchioles with intralesional Gram‐negative bacteria, immunolabelled with Escherichia coli immunohistochemistry.

Eighty calf blood samples were collected from different areas of China and were examined. Sixteen non cytopathic isolates of bovine viral diarrhea virus genotype 2 (BVDV-2) were isolated by specific BVDV-2-directed RT-PCR and sandwich ELISA. The results were verified by the indirect immunofluorescence assay and the ultra-thin sections. Genes of 5'-UTR,

Can a shorter peptide be a better antiviral? Structure‐guided optimization of the amphibian peptide Hs‐1 reveals a minimal α‐helical core that, after terminal modification, displays enhanced stability and submicromolar broad‐spectrum activity against enveloped viruses while maintaining a favorable safety profile. Antimicrobial peptides (AMPs) represent

Experimental infection of pregnant goats with bovine viral diarrhea virus (BVDV) 1 or 2 [PDF]
International audienceInfections with bovine viral diarrhea virus (BVDV) of the genus pestivirus, family Flaviviridae, are not limited to cattle but occur in various artiodactyls. Persistently infected (PI) cattle are the main source of BVDV.

ABSTRACT The detergent Triton X‐100 (TX‐100) is a typical component of solvent/detergent (S/D) mixes applied for virus inactivation steps of biomanufacturing processes, yet environmentally unfavorable properties have led to restrictions on its use. Deviron 13‐S9 has recently been described as an eco‐friendly TX‐100 alternative, with powerful virus ...
