is a Gram-negative bacterium found in natural and man-made water systems where it replicates within amoebas and ciliates. In humans, once inside the lungs, replicates in alveolar macrophages and causes Legionnaires' disease, a severe pneumonia. The Icm/Dot type IVb secretion system is a major virulence factor required for intracellular multiplication.

() is an inhabitant of natural and human-made water systems, where it replicates within amoebae and ciliates and survives within biofilms. When -contaminated aerosols are breathed in, can enter the lungs and may infect human alveolar macrophages, causing severe pneumonia known as Legionnaires' disease. is often found in hot water distribution systems (HWDS), which are linked to nosocomial outbreaks.

Surviving the nutrient-poor aquatic environment for extended periods of time is important for the transmission of various water-borne pathogens, including Legionella pneumophila (Lp). Previous work concluded that the stringent response and the sigma factor RpoS are essential for the survival of Lp in water. In the present study, we investigated the role of the LetA/S two-component signal transduction system in the successful survival of Lp in water.

The diversity and uniqueness of nematode heterotrimeric G-protein-coupled receptors (GPCRs) provides impetus for identifying ligands that can be used as therapeutics for treating diseases caused by parasitic nematode infections. In human medicine, GPCRs have represented the largest group of 'drugable' targets exploited in the market today. In the filarial nematode Dirofilaria immitis, which causes heartworm disease, the macrocyclic lactones (ML) have been used as the sole preventatives for more than 25 years and now there is confirmed ML resistance in this parasite.

Dirofilaria immitis, a filarial nematode, causes dirofilariasis in dogs, cats and occasionally in humans. Prevention of the disease has been mainly by monthly use of the macrocyclic lactone (ML) endectocides during the mosquito transmission season. Recently, ML resistance has been confirmed in D.

Dirofilaria immitis, a filarial nematode, causes dirofilariasis or heartworm disease in dogs, cats and wild canids. Effective prevention of the disease is mainly by the use of the macrocyclic lactone class of drugs as heartworm preventives, and no other class of drugs is effective for preventing infection. Macrocyclic lactones have been used for prevention of heartworm infection for more than 26years.

Haemonchus contortus is an abomasal nematode of ruminants that is widely present across the world. Its ability to cause death of infected animals and rapidly develop anthelmintic resistance makes it a dangerous pathogen. Ivermectin (IVM) and moxidectin (MOX) are macrocyclic lactones (MLs).

A homologue of Brugia malayi venom allergen (BmVAH) was cloned from the infective stages (L3) of Wuchereria bancrofti. Sequence analysis showed 90% sequence identity between WbVAH and BmVAH. Recombinant WbVAH was then expressed and purified.
