Peru, NE, United States

Peru State College is a public four-year liberal arts institution located in Peru, Nebraska, in the Midwest region of the United States. Founded by members of the Methodist Episcopal Church in 1865, making it the first and oldest institution in Nebraska, it would undergo several name changes before receiving its current name.The college is organized into three schools, each supporting a different set of majors, including a graduate program, plus an extensive online education program that is credited with the college's most recent successes. It occupies over twenty buildings on a beautiful 104-acre campus known as the "Campus of a thousand oaks". Wikipedia.


Prosorhynchoides fabulus n. sp. (Trematoda: Bucephalidae) is described from the intestine of white bass Morone chrysops (Moronidae) collected from the Neches River in the Big Thicket National Preserve in Texas, U.S.A. The new species is characterized by a relatively large cirrus sac extending anteriorly to the level of the ovary and cecum, a mouth nearly exactly midbody, obliquely arranged testes, a serpentine excretory bladder limited to the hindbody, and small size (<500 m). The extent of the cirrus sac distinguishes P. fabulus n. sp. from most other species in the genus in North America. The new species displays similarities to Prosorhynchoides carvajali, Prosorhynchoides labiatus, and Prosorhynchoides megacirrus in the extent of the cirrus sac but differs from these species in combinations of the location of the vitellaria, position of the pharynx and mouth, extent of the excretory bladder, arrangement and position of the gonads, and body size. © 2016 The Helminthological Society of Washington.


Lissorchis amniculensis n. sp. is described from the small intestine of creek chubsuckers collected from a small tributary stream of Big Sandy Creek in the Big Sandy Creek Unit of the Big Thicket National Preserve, Polk County, Texas, U.S.A. Members of the new species possess a distinct trilobed ovary, a feature found in individuals of 9 other species of Lissorchis. The new species is distinguished from these species by possessing a bipartite seminal vesicle with the distal portion larger than the proximal portion, vitelline follicles that extend beyond the posterior extent of the testes, a small posttesticular space, and a single dextral uterine loop that originates from the posttesticular space. © 2010 The Helminthological Society of Washington.


Protomagalhaensia cerastes n. sp. is described from nymphs and adults of the Pallid cockroach, Phoetalia pallida. Gamonts of Protomagalhaensia species are elongate and serpentine in general shape, but associated gamonts of P. cerastes are considerably smaller than those of other species of Protomagalhaensia. Primites and satellites of P. cerastes average total lengths of 323.1 μm and 317.9 μm, respectively; whereas similar stages range from 400.0 μm to 650.0 μm in the other 4 species within the genus. All species of Protomagalhaensia possess dolioform oocysts. Oocysts of Protomagalhaensia granulosae and Protomagalhaensia serpentula also possess apical corner spines or knobs that are absent in the oocysts of Protomagalhaensia wolfi, Protomagalhaensia blaberae, and P. cerastes. The oocysts of P. granulosae possess a lateral depression unique among members of the genus, while P. cerastes and P. wolfi possess distinct polar plates absent in other members of the genus. Oocysts of P. cerastes are notably smaller than those of P. wolfi in both length (7.3 μm vs. 9.2 μm) and width (4.5 μm vs. 5.5 μm). © 2010 The Helminthological Society of Washington.


Metacercariae of Panopistus pricei (Brachylaimidae) are common parasites of 2 species of terrestrial gastropods (Neohelix albolabris; Webbhelix multilineata) in southeastern Nebraska. Field data were collected to determine if individuals of N. albolabris and W. multilineata function as ecologically equivalent second intermediate hosts of P. pricei along a transect on the western edge of the Missouri River. Metacercariae were recovered and measured from samples of 30 snails of each species collected at each of 6 sites; whole kidneys from snails of both species were examined to quantify microhabitat use. Microhabitat use of P. pricei did not differ between host species; in both N. albolabris and W. multilineata, metacercariae were concentrated in the primary ureter and occurred throughout the kidney proper. Prevalences and mean abundances did not differ between host species at any site, nor did the relationship between parasite abundance and host size. Prevalences and mean abundances across sites were positively correlated between host species. At 2 sites, demographics of metacercariae differed between host species, suggesting short-term differences in the history of encounters with cercariae in the environment and differences in transmission to shrew definitive hosts. Overall, N. albolabris and W. multilineata appear to be equivalent and required second intermediate hosts of P. pricei in the area studied. © American Society of Parasitologists.


Tomaculocystis corpulenta n. gen., n. sp. (Apicomplexa: Eugregarinorida: Septatorina: Gregarinidae) is described from populations of the little yellow cockroach, Cariblatta lutea (Blattodea: Ectobiidae), established in laboratory culture from samples collected in Alabama and Florida. Tomaculocystis n. gen. are differentiated from other members of Gregarina by a markedly elliptoid gametocyst inside a persistent, lomentiform hyaline epicyst; developmental organization and growth of the spore tubes from gametocyst surface tumidi; and dehiscence by extrusion of non-chain forming oocysts through spore tubes that barely extend beyond the epicyst wall. Gregarina cylindrosa, Gregarina discocephala, and Gregarina mukundai are recognized as members of Tomaculocystis, and G. cylindrosa is recognized as the senior synonym of G. discocephala. Thus, Tomaculocystis cylindrosa n. comb. and Tomaculocystis mukundai n. comb. are formed. Species of Tomaculocystis are distinguished based on gamont deutomerite and oocyst shape and size. The oocysts of T. corpulenta are broadly dolioform, lack 4 polar knobs, and possess distinct, unique polar plates. Oocysts of all other known species in the genus are more oblong in shape, possess 4 polar knobs, and lack the distinct polar plates observed in the oocysts of T. corpulenta. Host utilization and geographic distribution among gregarine genera parasitizing the cockroach family Ectobiidae reveal a pattern of host-parasite specificity linking gregarine genera with ectobiidid subfamilies. Overall patterns suggest a hypothesis of European endemicy for Gamocystis, but hypotheses for the origin and radiation of Tomaculocystis or species of Gregarina infecting cockroaches are confounded by the cosmopolitan spread of pest cockroach species among humans. © 2015 American Society of Parasitologists.
