We used nucleotide sequences of the large subunit ribosomal genes (26S rDNA) to examine evolutionary relationships among species of the genus Pratylenchus (Order: Tylenchida, Family: Pratylenchidae), commonly known as root-lesion nematodes. Ten species of Pratylenchus were studied including, P. penetrans, P. crenatus, P. minyus, P. vulnus, P. thornei, P. musicale, P. coffeae, P. bexincisus, P. scribneri, and P. brachyurus. The species Hirschmanniella belli, Meloidogyne javanica, Heterorhabditis bacteriophora, Nacobbus eberruns, Radopholus similis, and Xiphinema index were used as outgroups. Based on parsimony analyses of approximately 307 …

Cucullanus Palmeri N. Sp. (Nematoda: Cucullanidae) From The Batfish Ogcocephalus Nasutus In The Gulf Of Mexico, John L. Crites, Robin M. Overstreet Feb 1997

Cucullanus Palmeri N. Sp. (Nematoda: Cucullanidae) From The Batfish Ogcocephalus Nasutus In The Gulf Of Mexico, John L. Crites, Robin M. Overstreet

---

Cucullanus palmeri n. sp. is described from the shortnose batfish, Ogcocephalus nasutus, in the Gulf of Mexico. This species is anatomically most similar to Cucullanus gendrei but differs from it in having a shorter esophagus and longer tail. Males differ in having a smaller gubernaculum and a different arrangement of a lateral caudal papilla. Cucullanus palmeri is readily distinguished from Cucullanus lophii, also from a lophiform fish host, in that the deirids and excretory pore are not posterior to the posterior end of the esophagus like in C. lophii.

---

Fecal samples from 56 Japanese bats representing 6 species in 2 families were examined for coccidian oocysts. Two of the 56 (< 4%) were infected with coccidia; however, only 1 animal was infected with sufficient numbers of sporulated oocysts to allow the description of a new species of Eimeria. Sporulated oocysts (n = 150) of this new species are subspheroidal, 20.3 x 18.1 (16-25 x 14-21) μm, with ellipsoidal sporocysts 10.6 x 6.6 (8-12 x 5-8) μm; this species occurred in 1 of 4 (25%) pipistrelles, Pipistrellus javanicus (Gray, 1838) (Vespertilionidae). Oocysts of another coccidium, also an Eimeria sp., were found in 1 of 3 (33%) horseshoe bats, Rhinolophus ferrumequinum (Schreber, 1774) (Rhinolophidae), but only 2 sporulated oocysts were seen, which is not enough …

The phylogeny of tapeworms provided the focus for the 2nd International Workshop for Tapeworm Systematics, which led to the development of novel hypotheses from the ordinal to the species level for taxa of the Eucestoda. Conceptual roots for this meeting ema­nated from discussions initiated during the Ist Workshop chaired by Claude Vaucher and Jean Mariaux at the Museum of Natural History, Geneva in 1993.

Phosphorylation Within The Amino-Terminal Acidic Domain I Of The Phosphoprotein Of Vesicular Stomatitis Virus Is Required For Transcription But Not For Replication, Asit K. Pattnaik, Leroy Hwang, Tong Le, Nathan Englund, Manjula Mathur, Tapas Das, Amiya Banerjee Jan 1997

Phosphorylation by casein kinase II at three specific residues (S-60, T-62, and S-64) within the acidic domain I of the P protein of Indiana serotype vesicular stomatitis virus has been shown to be critical for in vitro transcription activity of the viral RNA polymerase (P-L) complex. To examine the role of phosphorylation of P protein in transcription as well as replication in vivo, we used a panel of mutant P proteins in which the phosphate acceptor sites in domain I were substituted with alanines or other amino acids. Analyses of the alanine-substituted mutant P proteins for the ability to support …

Development Of A Protein-Free Chemically Defined Culture Medium For The Propagation Of The Oyster Pathogen Perkinsus Marinus, Jf Lapeyre, M Faisal Jan 1997

In the present study we describe a protein-free, chemically defined culture medium, designated JL-ODRP-3, which supports the propagation of Perkinsus marinus, a parasite of the eastern oyster, Crassotrea virginica. P. marinus adapted rapidly to the defined medium and the growth rate of the protozoan increased significantly following a few subcultures. Two isolates of P. marinus, one from the Chesapeake Bay (Virginia) and the other from the Gulf of Mexico (Texas) were cultured for at least ten passes. The doubling times far the isolates from Virginia and Texas, in Jog phase, were 18 +/- 1.2 and 28.6 +/- 3.2 hours respectively, …

Parasitological Examination Of Wasting Disease In Black Abalone, Haliotis Cracherodii : Final Report, Jeffrey D. Shields, Frank O. Perkins

Black abalone in southern California are afflicted with chronic intestinal infections of a rickettsia-like organism that causes a debilitating and fatal withering syndrome. The hematology of withered animals indicated that cellular degradation and apoptosis occurred in tandem with the · decline and catabolism of abalone tissues. Two types of hemocytes were found in the hemolymph. Type I and Type II Hyalinocytes were distinguished by subtle differences in their cytoplasmic vesicles. Densities of both types of hemocytes declined in abundance, and small, presumptive stem cells increased in abundance with the progression of the disease. No circulating granulocytes were present in hemolymph; …

Parasitological Data As Monitors Of Environmental Health, Robin M. Overstreet Jan 1997

Parasitological Data As Monitors Of Environmental Health, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

---

When an appropriate fish host is selected, analysis of its parasites offers a useful, reliable, economical, telescoped indication or monitor of environmental health. The value of that information increases when corroborated by another non-parasitological technique. The analysis of parasites is not necessarily simple because not all hosts serve as good models and because the number of species, presence of specific species, intensity of infections, life histories of species, location of species in hosts, and host response for each parasitic species have to be addressed individually to assure usefulness of the tool. Also, different anthropogenic contaminants act in a distinct manner …

Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg Jan 1997

Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

---

Emergence of pathogenic organisms continues as a threat to overall biodiversity and genetic resources. Macroparasites including helminths constitute a potential threat to economically important resources in agriculture and conservation biology. Limitation of this threat can be achieved through survey and inventory for biodiversity and the application of systematics to understand the host range , biogeography and history of faunas. Systematics constitutes the foundation for recognition of endemic and introduced elements of faunas and the basis for predicting the behavior of pathogens introduced to new ecological settings or host groups. The basis for emergence of pathogens has both a deep historical …

Isoelectric focusing was performed on extracts from Nematodirus spathiger, Nematodirus filicollis, Nematodirus helvetianus, and three geographic isolates of Nematodirus battus. Gender-specific differences were noted within species; however, the overall protein profile of each species and isolate was distinct and reproducible and allowed unequivocal differentiation. A coefficient of similarity (Sm) for males of each species and isolate was calculated, and a dendrogram, based on evaluation of Sm by the unweighted pair-group method with arithmetic means, was produced. Although cluster analysis of the three isolates of N. battus indicates the North American and Weybridge isolates are similar, interpretation …

Offspring of four crosses (I, II, III, and IV) of Penaeus vannamei from known high- and low-growth families were challenged with infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Baculovirus penaei (BP) to compare their susceptibility to these viral agents and examine the genetic component involved in disease resistance or susceptibility. Family crosses were made using broodstock from five families developed by the U.S. Marine Shrimp Farming Program. The prevalence of IHHNV infection was highest in cross I and lowest in cross III. Cross I was developed using male and female broodstock from the low-growth family 1.6, and cross III …
