Abstract Inversions of the origin of replication (ORI) of mitochondrial genomes produce asymmetrical mutational pressures that can cause artefactual clustering in phylogenetic analyses. It is therefore an absolute prerequisite for all molecular evolution studies that use mitochondrial data to account for ORI events in the evolutionary history of their dataset.

Abstract Since its introduction approximately seven years ago, selamectin (Stronghold®/Revolution®, Pfizer Inc.) has been used off-label to treat a number of ecto- and endoparasite conditions in dogs and cats. It has been used as a successful prophylactic against Dirofilaria repens and as a treatment for Aelurostrongylus abstrusus in cats. It has also been used to treat notoedric mange, infestation with the nasal mite Pneumonyssoides caninum, Cheyletiella spp. and Neotrombicula autumnalis infestations and larval Cordylobia anthropophaga infection. However, to date attempts to treat generalised canine demodicosis have not been successful. In all cases, treatment was apparently well tolerated by the host. Background [3].

  • Feline Immune Response to Infection with Cytauxzoon Felis and The
    FELINE IMMUNE RESPONSE TO INFECTION WITH CYTAUXZOON FELIS AND THE ROLE OF CD18 IN THE PATHOGENESIS OF CYTAUXZOONOSIS by KARELMA FRONTERA-ACEVEDO (Under the Direction of Kaori Sakamoto) ABSTRACT Cytauxzoonosis is a highly fatal, hemoprotozoal disease of cats in the Mid-Western, Mid- Atlantic, and Southeastern United States, caused by Cytauxzoon felis. Although the causative agent has been recognized since 1976, no study has profiled the immune response of infected cats, there is no definitive cure, and C. felis has not been successfully maintained in cell cultures in vitro, thwarting research efforts. One of the main histopathologic characteristics of this disease is the presence of giant, infected, intravascular macrophages, many of which are adhered to the vascular endothelium. The main goals of this project are: 1) to characterize the feline immune response to C. felis; 2) to develop a cell culture system in order to study C. felis in vitro; and 3) to determine whether CD18 plays a role in the pathogenesis of cytauxzoonosis.

  • The Trematode Parasites of Marine Mammals
    THE TREMATODE PARASITES OF MARINE MAMMALS By Emmett W. Pkice Parasitologist, Zoological Division, Bureau of Animal Industry United States Department of Agriculture The internal parasites of marine mammals have not been exten- sively studied, although a fairly large number of species have been described. In attempting to identify the trematodes from mammals of the orders Cetacea, Pinnipedia, and Sirenia, as represented by specimens in the United States National Museum helminthological collection, it was necessary to review the greater part of the litera- ture dealing with this group of parasitic worms. In view of the fact that there is not in existence a single comprehensive paper on the trematodes of these mammals, and that many of the descrip- tions of species have appeared in publications having more or less limited circulation, the writer has undertaken to assemble descriptions of all trematodes reported from these hosts, with the hope that such a paper may serve a useful purpose in aiding other workers in de- termining specimens at their disposal. In addition to compiling the descriptions of species not available to the writer, two new species, one of which represents a new genus, have been described. Specimens representing 10 of the previously described species have been studied and emendations or additions have been made to the existing descriptions; in a few instances the species have been completely reclescribed. Three species, Distoinwni pallassil Poirier, D. vaUdwim von Lin- stow, and D. am/pidlacewni Buttel-Reepen, have been omitted from this paper despite the fact that they have been reported from ceta- ceans. These species belong in the family Hemiuridae, and since all species of this family are parasites of fishes, the writer feels that their reported occurrence in mammals may be regarded as either errors of some sort or cases of accidental parasitism in which fishes have been eaten by mammals and the fish parasites found in the mammal post-mortem.

Several new validated scoring systems functional immunity. Alterations of the peaceful coexis- to measure the severity of autoimmune blistering dis- tence with the resident microbiota, referred to as dys- ease (AIBD) have been developed which assist in biosis, lead to dysregulation of host immunity.
