New host and distribution records of the gill parasite Dactylogyrus sphyrnoides Gussev, 1976 (Platyhelminthes, Monogenoidea) on a Near Threatened Tor Barb, Tor tor (Hamilton, 1822) (Teleostei, Cyprinidae), in northeastern India [PDF]
The parasitic monogenoid Dactylogyrus sphyrnoides Gussev, 1976 was recorded for the first time on the gills of the Near Threatened freshwater fish Tor tor (Hamilton, 1822) that was collected in northeastern India. Dactylogyrus sphyrnoides was originally

A review the various patterns of tick-host relationships are discussed in detail in order to answer the following questions : 1. How, when and where did host specificity of each parasite group evolve ? 2. How strict is specificity in each case ? 3. Why and under what circumstances does specificity break down ?

Host Specificity of Bacterial Pathogens [PDF]
Most pathogens are able to infect multiple hosts but some are highly adapted to a single-host species. A detailed understanding of the basis of host specificity can provide important insights into molecular pathogenesis, the evolution of pathogenic microbes, and the potential for pathogens to cross the species barrier to infect new hosts.

Influenza A Virus–Host Specificity: An Ongoing Cross-Talk Between Viral and Host Factors
One big threat from influenza A viruses (IAVs) is that novel viruses emerge from mutation alongside reassortment. Some of them have gained the capability to transmit into human from the avian reservoir. Understanding the molecular events and the involved

Host specificities of RNA phages [PDF]
SUMMARYHost ranges of members of four groups of male-specific RNA coliphages were determined by plating on hosts carrying various derepressed plasmids. An RNA phage originally isolated onPseudomonas aeruginosafailed to form plaques on any of the strains ofEscherichia coli.

Host specialization of different populations of ergot fungus (Claviceps purpurea)
In our previous study of Claviceps purpurea three populations were found: G1 on open localities, G2 from shady or wet habitats and G3 on Spartina stands of coastal salt marshes. The latter two are also chemoraces.

Lice, Mites, and Ticks of Southeastern Wisconsin Mammals [PDF]
Seventeen species of southeastern Wisconsin mammals were found to 6e infected with arthropod ectoparasites other than fleas. One host species was infested with one species of biting lice (Mallophaga), five with five species of sucking lice (Anoplura ...
