Interplay between and during In Vitro Infection of a Chicken Macrophage Cell Line (HD11).

Background: is a frequent intestinal pathogen of chickens, causing economic impact on the poultry industry. is a neglected parasite in chickens. However, because of its zoonotic potential, poultry cryptosporidiosis may pose a risk to public health.

Octaarginine Improves the Efficacy of Nitazoxanide against .

Cryptosporidiosis is an intestinal disease that affects a variety of hosts including animals and humans. Since no vaccines exist against the disease till date, drug treatment is the mainstay of disease control. Nitazoxanide (NTZ) is the only FDA-approved drug for the treatment of human cryptosporidiosis.

In vitro infection of Madin-Darby bovine kidney (MDBK) cells with Eimeria acervulina sporozoites: quantitative analysis of parasite cellular invasion and replication using real-time polymerase chain reaction (PCR).

Poultry coccidiosis causes considerable economical losses to the livestock industry. Eimeria parasites are responsible for this disease. On a global scale, E.

A SYBR green I real-time polymerase chain reaction (PCR) assay for detection and quantification of Trichomonas gallinae.

Trichomonas gallinae are parasitic flagellates of importance in wild and domestic birds. The parasite is worldwide distributed, and Columbine birds are its main host. Current research focuses mostly on epidemiological and phylogenetic studies.

A simple and efficient transfection protocol for using Polyethylenimine (PEI) and Octaarginine.

The transfection of Cryptosporidium represents a major challenge, and current protocols are based on electroporation of freshly excysted sporozoites using a rather large amount of plasmid DNA which typically has a very poor yield. In this study, we report a fast and simple protocol for transfection of Cryptosporidium parvum that takes advantage of the DNA condensing power of the poly cationic polymer polyethylenimine (PEI) and the gene delivery property of the short cell-penetrating peptide octaarginine. Our novel protocol requires a very low amount of plasmid DNA and does not necessitate special laboratory equipment to be performed.

Extended-spectrum β-lactamase- and AmpC β-lactamase-producing D-tartrate-positive Salmonella enterica serovar Paratyphi B from broilers and human patients in Belgium, 2008-10.

Objectives: To characterize the genetic determinants responsible for extended-spectrum cephalosporin (ESC) resistance of d-tartrate-positive Salmonella enterica subsp. enterica serovar Paratyphi B (serovar Paratyphi B dT+) strains that have emerged in poultry and humans in Belgium during 2008-10.

Methods: The ESC resistance genes among non-redundant serovar Paratyphi B dT+ strains were determined using PCR and sequencing.
