Ontogeny and differentiation of cells of the monocyte/macrophage lineage are currently subjects of intense research. The concept of the macrophage as “simple” phagocytic cell has undergone profound changes. It has now been established that this myeloid lineage of cells is phenotypically and functionally much more diverse and exerts a much wider ...

The immune system represents a complicated assemblage of coordinated genes, proteins, cells and tissues. The field of ecological immunology (EI) is founded on the assumption that immunological defenses incur costs (energetic or fitness) under different ecological conditions.

Pathophysiological Aspects of Ocular Toxoplasmosis: Host-parasite Interactions
Ocular immunology and inflammation, 2021Purpose This review aims to present the state of the art to understand the pathophysiology of ocular toxoplasmosis (OT), providing further foundations that would help to improve the future treatment and prognosis of this potentially blinding disease ...

Host-Parasite Interaction in the Urinary Tract [PDF]
Journal of Urology, 1988 The term urinary tract infection (UTI) describes a heterogeneous group of disorders localized to the urinary tract [1]. Bacteriuria may be associated with clinical conditions of varying severity and consequence. The analysis of these conditions may be based on several factors.

Host—Parasite Interactions in Molluscs [PDF]
, 1996 The phylum Mollusca is second only to the Arthropoda in both number and diversity of living species. Representatives include not only the readily recognized gastropods (snails, slugs and limpets) and bivalves (e.g., oysters, mussels and clams) but also the ‘brainy’ cephalopods including octopus and squid, and more primitive representatives such as ...

Genetics of host-parasite interactions
Trends in Ecology & Evolution, 1997The evolution of host susceptibility or resistance to parasites has important consequences for the evolution of parasite virulence, host sexual selection, population dynamics of both host and parasite populations, and programs of biological control. The general observation of a fraction of Individuals within a population that is not parasitized, and/or

Stochastic host-parasite interaction models
Journal of Mathematical Biology, 2000We contribute to the discussion of causes and effects of aggregation (overdispersion) of macroparasite counts, focussing particularly upon the effects of clumped infections and parasite-induced host mortality. The simple nonlinear stochastic model for the evolution of the parasite load of a single host, investigated in Isham (1995), is extended to ...

Host–parasite interactions in a fragmented landscape
International Journal for Parasitology, 2013Theory suggests that habitat fragmentation should reduce the risk of being parasitised due to reduced size and increased isolation of the host population. It is predicted that a threshold host population size exists, below which parasites will not be able to persist.

Local adaptation and host–parasite interactions
Trends in Ecology & Evolution, 1998The reciprocal transplant experiment is a test to detect the existence of adaptive genetic structure. It compares the performance of parasites (e.g. infectivity, within-host growth rate and survival) on native and novel environments (which can be different host individuals, populations, or species). Controls are required for the conditioning effects of
