The Campylobacter genus includes many pathogenic species, with Campylobacter hepaticus primarily implicated in spotty liver disease in poultry. Chemotaxis is one of the well-established mechanisms of pathogenesis of Campylobacter. The chemoreceptor Tlp3,

Investigating the role of chemotaxis operon genes in agrobacterium tumefaciens [PDF]
A 1.7 Kb chromosomal DNA of A. tumefaciens C58C1 downstream of chemotaxis operon was sequenced completely in both directions. The comparison of this sequence with sequence databases revealed one open reading frame with strong sequence identity to MCP ...

Opposing effects of dopamine receptor blockade on ventilation and carotid chemoreceptor activity
To determine the effects of dopamine receptor blockade on the ventilatory responses to hypoxia and hypercapnia we simultaneously measured ventilation and carotid chemoreceptor activity in eight anesthetized cats. During normoxia, haloperidol (1 mg .

Effects of mitochondrial poisons on glutathione redox potential and carotid body chemoreceptor activity [PDF]
Producción CientíficaLowoxygen sensing in chemoreceptor cells involves the inhibition of specific plasma membrane K+ channels, suggesting that mitochondria-derived reactive oxygen species (ROS) link hypoxia to K+ channel inhibition, subsequent cell ...

Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Arterial chemoreceptor input to respiratory hypoglossal motoneurons
To better understand the role of the arterial chemoreceptors in the regulation of upper airway patency at the level of the oropharynx, intracellular recordings were obtained from inspiratory hypoglossal motoneurons (IHMs), and the responses to selective

Postnatal developmental changes in the laryngeal chemosensory cell clusters of rats
Chemosensory cell clusters appeared in the rat larynx 2 days after birth and were already connected to afferent nerve fibers. Their number increased until 3 weeks of age, then stabilized while continuing to grow through the addition of new cells. Because their number reached a plateau around the time of weaning, their development may be linked to ...

Differential effects of oligomycin on carotid chemoreceptor responses to O2 and CO2 in the cat
Effects of oligomycin on carotid chemoreceptor responses to O2 and CO2 were investigated using an in situ perfusion technique. Cats were anesthetized, paralyzed, and artificially ventilated.

We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...
