Novel Information On The Morphology, Phylogeny And Distribution Of Camallanid Mematodes From Marine And Freshwater Hosts In South Africa, Including The Description Of Camallanus Sodwanaensis N. Sp., Roman Svitin, Marliese Truter, Olena Kudlai, Nico J. Smit, Louis Du Preez

Harold W. Manter Laboratory: Library Materials

Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx, and Procamallanus pseudolaeviconchus from the catfish Clarias gariepinus and Spirocamallanus daleneae from the catfish Synodontis zambezensis. In the material collected from various marine fishes, several specimens of nematodes from the genus Camallanus clearly differed from all previously known species. Based on morphological differences these specimens are assigned to a new species, C. sodwanaensis. Molecular data of 18S and 28S rDNA and COI sequences are provided for the collected species …

Pentastomids Of Wild Snakes In Australia, Crystal Kelehear, David M. Spratt, Denis O'Meally, Richard Shine

Harold W. Manter Laboratory: Library Materials

Pentastomids are endoparasites of the respiratory system of vertebrates, maturing primarily in carnivorous reptiles. Adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts. The study of pentastomids is a neglected field, impaired by risk of zoonoses, difficulties in species identification, and life cycle complexities. We surveyed wild snakes in the tropics of Australia to clarify which host species possess these parasites, and then sought to identify these pentastomids using a combination of morphological and molecular techniques. We detected pentastomid infections in 59% of the 81 snakes surveyed. The ubiquity of pentastomid …

The Coccidian Parasites (Protozoa, Sporozoa) Of Rodents, Norman D. Levine, Virginia Ivens

Harold W. Manter Laboratory: Library Materials

This monograph summarizes the known information on taxonomy, morphology, life cycle, hosts, location in the host, pathogenicity, geographic distribution, and cross-transmission studies of the 196 named species of coccidia of rodents. These include 176 species of Eimeria, 9 of Isospora, 3 of Wenyonella, 2 each of Cryptosporidium and Klossiella, and 1 each of Dorisiella, Caryospora, Tyzzeria, and Klossia. In addition, similar data are given for those forms for which insufficient information is available to justify assigning them names.

Eimeria, which is the most common genus, has been described from only 15% …

The Tapeworms Of The Rhinoceroses, A Study Based On Material From The Belgian Congo, Horace W. Stunkard

Harold W. Manter Laboratory: Library Materials

During the course of my study on the parasitic worms collected by the Lang-Chapin expedition of the American Museum to the Belgian Congo, I have had the good fortune to examine abundant material of Plagiotaenia gigantea (Peters). This interesting species, the first reported from the rhinoceros, has been confused with other cestodes from rhinoceros hosts, has been assigned to no less than three different genera in addition to the genus Taenia, to which it was originally referred, and has been the source of much discussion and difference of opinion during the past seventy years. A review of the literature …

Trematodes From The Rat, Horace Wesley Stunkard, Chilson B. Haviland

Harold W. Manter Laboratory: Library Materials

Occasional examinations of rats for animal parasites have been carried on for over a hundred years. Later, knowledge of the importance of rats as reservoirs of infection and as agents in the transfer of parasitic diseases has led to the regular and careful examination of large numbers in various parts of the world. Among the more recent publications dealing with the parasites of rats may be mentioned Shipley (1908), Moll (1917), Chandler (1921), Balfour (1922), Baylis (1922), Stevenson (1922), Hegner (1923), and Lavier (1924). Notwithstanding the many investigations, only a single trematode parasite has previously been discovered and concerning it …

Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley

Harold W. Manter Laboratory: Library Materials

Excerpt:

The danger in using isolated sentences from an article as a basis for interpreting the author's theories, is generally recognized, but sometimes the most careful workers fall into the trap. Once the mistaken interpretation is published, it may be copied over and over again until it rises to the dignity of a dogma.

A striking illustration is afforded by the practical unanimity with which writers on the subject of insects and disease credit Dr. Josiah Nott with being the earliest to formulate definitely the theory of mosquito transmission of yellow fever.

Nuttall, in his classic monograph On the Role …
