This is the first survey of baboon gastrointestinal parasites in Ghana and provides baseline data for this area. Ninety-three percent of samples were infected, leaving 7% with no parasites observed. Of those infected, there was a 76% prevalence of Strongyles, 53% Strongyloides spp., 11% Abbreviata caucasica, 62% prevalence of Balantidium coli (trophozoites and cysts identified), 4% Entomeba hystolytica/dispar and 47% unidentified protozoan parasites. Of the strongyle infections, 9% were identified as Oesophagostamum s...

To ascertain the identities of parasitic nematodes, given the distorted or damaged nature of the specimens, molecular techniques were applied in the form of DNA barcoding. To our knowledge, this is the first application of this technique to an obviously cultural concern, as opposed to one of health or economic significance. Results, based both on cytochrome c oxidase subunits I and II suggested that the parasite spec...

In the present study, serum samples from 288 dogs were collected from Xuzhou, Huaiyin and Yianchen in Jiangsu Province, eastern China in August 2010, and detected T. gondii antibodies by a modified agglutination test (MAT). Antibodies to T. gondii were found in 62 of 288 (21.5%), with MAT titers of 1:25 in 21 dogs, 1:50 in 15 dogs, 1:100 in 11 dogs, 1:200 in 6 dogs, 1:400 and above in 3 dogs. The seroprevalence in dogs ≥3 year-old was significantly higher (p<0.05) than that in dogs <3 year-old. The results of the present study indicated that infection with T. gondii in household dogs in Jiang...

J Parasitol. 2012 Feb 2; Authors: Zelmer DA, Brewer SA, Hanlin HG Abstract Abstract Flier (Centrarchus macropterus: Centrarchidae) were collected from a channel habitat, a prairie habitat, and from a boundary between the 2 habitat types in March of 2009, and examined for parasites. Flier from the prairie site had a significantly lower abundance of Pterocleidus acer, and a significantly higher abundance of Hysterothylaceum juveniles. Patterns of infracommunity similarity showed a distinct break between the 2 habitat types, with fish collected from the boundary site clustering with either channel or prairie communities, suggesting that the small home range of flie...

While this maternal care has been suggested to occur in different argasid tick species, it has been recorded only once, for Antricola marginatus in Cuba; however, this earlier record only superficially mentioned the occurrence of this behavior, with no further details. Here, we report the occurrence of maternal care in the argasid tick A. marginatus under natural conditions in a cave at Yucatan, Mexico, where 8 A. marginatus females, while walking on bat guano, had their body entirely covered by a mea...

J Parasitol. 2012 Jan 30; Authors: Pinto HA, de Melo AL Abstract Abstract Melanoides tuberculata naturally infected by gymnocephalous cercariae were found in aquatic collections from Belo Horizonte, Minas Gerais, Brazil. After morphological characterization, larvae were used for experimental infection of Poecilia reticulata. Metacercariae were obtained from the liver of these fish, which were also found to be naturally infected in the same locality. The morphology and biology of the developmental stages of trematodes obtained were characteristic of Renicola sp. This is the first record of renicolid cercariae and metacercariae in Brazil.

J Parasitol. 2012 Jan 30; Authors: Zehtindjiev P, Križanauskienė A, Bensch S, Palinauskas V, Asghar M, Dimitrov D, Scebba S, Valkiunas G Abstract Abstract Plasmodium polymorphum n. sp. (Haemosporida, Plasmodiidae) was found in the skylark Alauda arvensis (Passeriformes, Alaudidae) during autumnal migration in southern Italy. This organism is illustrated and described based on the morphology of its blood stages. The most distinctive feature of this malaria parasite is the clear preference of its blood stages (trophozoites, meronts and gametocytes) for immature red blood cells, including erythroblasts. Based on preference...

J Parasitol. 2012 Jan 20; Authors: Trout K, Clopton RE Abstract Abstract Gametocytogenesis was induced in mature associations of Protomagalhaensia wolfi and Protomagalhaensia blaberae maintained in vitro by inclusion of metronidazole in the culture medium. The response is neither strictly dosage dependent nor uniform across gregarine species. We hypothesize that metronidazole induces gregarine gametocytogenesis by disrupting PUF2 proteins responsible for the translational control of sexual development and gametocystogenesis in apicomplexans.

J Parasitol. 2012 Jan 20; Authors: Rangel LF, Azevedo C, Casal G, Santos MJ Abstract Abstract The ultrastructure of Ellipsomyxa mugilis' spores and developmental stages in Nereis diversicolor were studied by transmission electron microscopy. The ultrastructure features and the developmental stages show many similarities with the general pattern described for other actinospores. However, several new features are definitely worth notice. For example, tetranucleated cells precedes the formation of the initial pansporocyst, which preserves the 2 original enveloping cells until the end of sporogony. In the initial stages of sporo...

The species richness encountered was low with only 3 species of nematodes (Longistriata bathyergi, Mammalakis macrospiculum and Trichostrongylus sp.) and 2 species of cestodes (Taenia sp. and Rodentolepis sp.). At less than 10%, the prevalence for all helminths species was similarly low and may be a result of the solitary life style and the subterranean habitat exploited by this rodent. Clear seasonal patterns were apparent for the most common nematode (L. bathyergi) and prevalence and abundance were highest among non-pregnant females compared to males and pregnant females. Dispersal patterns associa...

Most infected stickleback harbored a single large plerocerciod (mean weight = 0.447 g, range = 0.228-0.716 g). The overall prevalence of plerocercoids across genders and 2 yr of samples was 1.36%, but prevalence was significantly greater in males than in females. Because of the large size of the plerocercoids, anadromous stickleback were probably infected as juveniles before leaving the lake, suggesting that plerocercoids can live in the body cavity of oceanic stickleback for several yr.

IN BLUE CRABS, CALLINECTES SAPIDUS. J Parasitol. 2012 Jan 18; Authors: Coffey AH, Li C, Shields J Abstract Abstract ABSTRACT: The parasitic dinoflagellate Hematodinium sp. parasitizes blue crabs along the Atlantic seaboard of the USA. Infections in blue crabs have only been reported from waters >11 psu salinity. Blue crabs maintain a hyperosmotic internal concentration at low salinities (0-5 psu) roughly comparable to 24 psu, and should be capable of maintaining an infection in low salinity waters, even if Hematodinium sp. cells are intolerant of low salinities. We tested this notion by observing the effect of low salinity on the progression of disease in crabs experimentally infected with the parasit...

The sequenced genome of Bd provides information necessary for studying the fungus and its molecular biology. Fluorescent microscopy is a technique used to image targeted molecules in live or fixed organisms to understand cellular trafficking and localization, but the use of fluorescent microscopy with Bd has not yet been demonstrated. Two fluorescent stains were tested for their use in live cell imaging of Bd, i.e., the cell wall-specific fluorophore Solophenyl Flavine 7GFE and the DNA-specific fluorophore DRAQ5. These specific staining patterns were observed in live cultures of Bd when visualize...

Seventy-five percent of the clutches presented multiple paternity with a mode of 2 fathers siring the clutch. Males associated with the females on the host always sired some offspring. In 1 case, a male was the sire of clutches derived from 2 females indicating both polygyny and polyandry may occur for this species. These results, combined with those of several other recent studies, suggest that multiple paternity might be frequent for ixodid ticks.

A concordance between natural and experimental data show a preference for the shells of multiple species of snail over other hard substrata that are common at the field site, including seaweed, other molluscs, and crustaceans. Additionally, we found that cercariae preferred substrata with pre-existing cysts, and that this preference appeared to increase with increasing cyst density. Such a preference should lead to an aggregated distribution of cysts among snail shells, which may benefit the parasite by increasing the number of poten...

In the Klamath River (California), current thermal conditions are considered sub-optimal for juvenile salmon. In addition to borderline temperatures, these fish must contend with the myxozoan parasite Ceratomyxa shasta, a significant cause of juvenile salmonid mortality in this system.

In the Klamath River (California), current thermal conditions are considered sub-optimal for juvenile salmon. In addition to borderline temperatures, these fish must contend with the myxozoan parasite Ceratomyxa shasta, a significant cause of juvenile salmonid mortality in this system.

A concordance between natural and experimental data show a preference for the shells of multiple species of snail over other hard substrata that are common at the field site, including seaweed, other molluscs, and crustaceans. Additionally, we found that cercariae preferred substrata with pre-existing cysts, and that this preference appeared to increase with increasing cyst density. Such a preference should lead to an aggregated distribution of cysts among snail shells, which may benefit the parasite by increasing the number of poten...

J Parasitol. 2011 Nov 16; Authors: Campião KM, Delatorre M, Rodrigues RB, Silva RJ, Ferreira VL Abstract Abstract Understanding the patterns of species distribution and abundance has been at the core of ecology. In general, these patterns are determined by species dispersion, as well as abiotic and biotic environmental conditions. Similarly, host parasite relations and the structure of parasite assemblages are also shaped by environmental conditions and landscape composition. Herein, we assessed the influence of environmental variables and parasite species dispersion on the structure of helminth parasites ...

We report that as G. intestinalis progresses through its growth cycle, cultures of trophozoites accumulate glycogen during the lag and early logarithmic phases of growth, then utilize this compound during their remaining logarithmic growth. As cultures enter the stationary phase of growth, they re-accumulate glycogen stores. The activity of glycogen phosphorylase, an enzyme involved in glycogen metabolism, also varied throughout in vitro trophozoite growth. During the in vitro induction of trophozoite differentiation into water-resistant cyst forms, the cultures initially accumulated stores of glycogen, w...

J Parasitol. 2011 Nov 14; Authors: Rossiter W, Sukhdeo MV Abstract Abstract Several studies have suggested that the fitness of a parasite can be directly impacted by the quality of its host. In such cases, selective pressures could act to funnel parasites towards the highest quality hosts in a population. The results of this study demonstrate that snail host quality is strongly correlated with spatial patterning in trematode infections, and that habitat type is the underlying driver for both of these variables. Two trematodes (Himasthla quissetensis and Zoogonus rubellus) with very different life cycles assume the ...

Natural infection of schistosomes induces very little protective immunity against reinfection. Moreover, effective schistosomiasis vaccines for practical use have not been developed. Schistosomes appear to have evolved highly effective modulatory mechanisms on their host's immune system that promote the parasites' survival and also hinder the development of effective strategies for treatment of the disease. Understanding of the mechanisms of schistosome-mediated immune-modulation would be most helpful in schistosomiasis prevention and control. Previously, ...

However, the detail profile of the 5' UTR for Toxoplasma gondii has not demonstrated yet. To investigate the issue, we compared the predicted ORFs and transcription start sites (TSSs) of T. gondii obtained by TSS-seq, a method which enables to analyze encyclopedic TSSs with next-generation sequencers. As a result, it was demonstrated that the mode length of the 5' UTR distributes between 120 and 140 nts when a subset of genes with predicted signal peptides was examined. On the contrary, when genes without the signal peptide were examined, the length was extended to around 600 nts (nucleotides). Because additi...

The barn owls in our study were infested with 3 species of lice (Phthiraptera: Ischnocera): Colpocephalum turbinatum, Kurodaia subpachygaster, and Strigiphilus aitkeni. Bill hook length was associated with the prevalence of these lice. Owls with longer hooks were more likely to be infested with lice. Conventional wisdom suggests that the bill morphology of raptors has been shaped by selection for efficient foraging; our data suggest that hook morphology may also play a role in ectoparasite defense. The number of teeth on the pectinate claw was also associated with the prevalence of lice. Owls...

J Parasitol. 2011 Oct 18; Authors: Oladiran A, Belosevic MM Abstract Abstract Trypanosomes are digenetic protozoa that infect domestic and wild animals, as well as humans. They cause important medical and veterinary diseases, making them a major public health concern. There are many species of trypanosomes that infect virtually all vertebrate taxa. They typically cycle between insect or leech vectors and vertebrate hosts, and undergo biochemical and morphological changes in the process. Trypanosomes have received much attention in the last 4 decades because of the diseases they cause and their remarkable armamentarium of immune evasion mechanisms. The completed genome sequences of trypanosomes have revealed an extensive ...

Infected ants exhibit altered behavior, e.g., reduced aggression and slower tempo, as well as physical traits, e.g., gaster changes from shiny black to bright red. These changes are thought to induce fruit mimicry and attract frugivorous birds, which are the presumed paratenic hosts for the nematodes.

Further analyses of coprolites from Antelope Cave revealed additional parasitological data from coprolites of both human and canid origin. A second tick was found. This site is the only archaeological locality where ticks have been recovered. We also discovered an acanthocephalan in association with Enterobius vermicularis eggs in the same coprolite. This association shows that the coprolite was deposited by a human. This discovery expands our knowledge of the range of prehistoric acanthocephalan infection. In addition, findings from canid coprolites of Trichuris vulpis are reported. This is t...

J Parasitol. 2011 Oct;97(5):775-8 Authors: Heins DC, Baker JA Abstract abstract :  The diphyllobothriidean cestode Schistocephalus solidus typically infects threespine sticklebacks that are too small to allow the parasite to reach a mature size. As a result, the parasite must allow further growth of its host to reach the size at which it becomes competent to infect and reproduce in the definitive host. At times, however, intensity of infection can be high, leading to crowding among parasites and to heavy burdens causing mortality among hosts. Our data show that, during a previously observed epizootic, large percentages of plerocercoids (average 75% per host...

However, this cercaria does not possess obvious eyes or eyespots. Using behavioral assays, we were able to show that both intact and distome-removed cercariae swim significantly greater vertical distances under dim, red light than under brighter, white light.

The finding of G. agilisis in a different, albeit closely related, host species strengthens the previous notion of a close association between pinworms and didelphids and contributes to the knowledge of the helminthic fauna of didelphid marsupials.

J Parasitol. 2011 Sep 23; Authors: Koop JA, Huber SK, Clayton DH Abstract Abstract Preening is a bird's first line of defense against harmful ectoparasites. Ectoparasites, in turn, have evolved adaptations for avoiding preening, such as hardened exoskeletons and escape behavior. Earlier work suggests that some groups of ectoparasites, such as feather lice, leave hiding places in feathers that are exposed to direct sunlight, making them more vulnerable to preening. It is therefore conceivable that birds may choose to preen in direct sunlight, assuming it improves the effectiveness of preening. Using Mourning doves and their feather lice, we tested two related hypotheses: 1) that birds with a...

J Parasitol. 2011 Sep 19; Authors: Keeler SP, Yabsley MJ, Gibbs SE, McGraw SN, Hernandez SM Abstract Abstract Seven thrush species (Turdidae) from Costa Rica were examined for intestinal parasites; 21 of the 84 (25%) birds sampled were positive for a new species of Isospora. Oocysts of Isospora zorzali n.sp. have thin, smooth, double, and colorless walls; they measure 19.7 µm + 1.5 µm x 18.6 µm + 1.4 µm (16-24 µm x 15-21 µm), with an average length-width ratio of 1.1 µm. Sporocysts are ovoid, measure 8.5 µm + 1.1 µm x 14.5 µm + 1.7 µm (7-11 µm x 11-18 µm) with an average length-width ratio of 1.7 µm. A nipple-like stieda body continuous with the sporocyst wall is present, but no subst...

J Parasitol. 2011 Sep 19; Authors: Herrmann KK, Poulin R Abstract Abstract Numerous parasite species have evolved complex life cycles with multiple, subsequent hosts. In trematodes, each transmission event in multi-host life cycles selects for various adaptations, one of which is facultative life cycle abbreviation. This typically occurs through progenesis, i.e., precocious maturity and reproduction via self-fertilization within the second intermediate host. Progenesis eliminates the need for the definitive host and facilitates life cycle completion. Adopting a progenetic cycle may be a conditional strategy in response to environmental cues related to low probability of transmission to the definitive h...

J Parasitol. 2011 Sep 16; Authors: Arulsundari A, Bogdanowicz WB, Ragu Varman D, Marimuthu G, Koilmani ER Abstract Abstract To study variation in infestations by the bat fly Raymondia lobulata (Diptera: Streblidae) on the greater false vampire bat Megaderma lyra (Chiroptera: Megadermatidae), we captured individual bats at their day roost in the south of India and recorded their rate of infestation continuously for a year. All examined bats (n = 72 individuals, 202 captures) were infested with parasites (n = 3,008). However, the recorded intensity of infestation (range 1-33) was gender-related, and statistically higher in females than ...

J Parasitol. 2011 Sep 14; Authors: Alvarado-Esquivel C, García-Machado C, Alvarado-Esquivel D, Vitela-Corrales J, Villena I, Dubey JP Abstract Abstract The seroprevalence of Toxoplasma gondii infection in sheep in northern Mexico is largely unknown. Antibodies to T. gondii were determined in serum samples from 511 sheep from 8 farms in Durango State, Mexico using the modified agglutination test (MAT). Sheep were raised in 3 geographical regions: mountainous (n=68), semi-desert (n=132), and valley (n=311). Overall, T. gondii antibodies were found in 77 (15.1%) of 511 sheep, with MAT titers of 1:25 in 27, 1:50 in 10, 1:100 in 11, 1:200 in 11, 1:400 in 8, 1:800 in 3, 1:1,600 in 4, and 1:...

J Parasitol. 2011 Sep 6; Authors: Heins DC, Ecke JK Abstract Abstract Epizootics of diphyllobothriidean cestodes appear to be simple, but deceptive similarity conceals the myriad ways in which these events are shaped by complex abiotic and biotic interactions. In Dog Bone Lake, Alaska, an epizootic of Schistocephalus pungitii infecting the ninespine stickleback (Pungitius pungitius) was short-lived. Its duration, with a peak that lasted only 1 yr, was shorter than for previously documented epizootics in Schistocephalus solidus. The ability of the ninespine stickleback to sustain infections, which appears to be related to species-specific charact...

The ectoparasite and helminth faunas of Pseudomys delicatulus, P. desertor, P. gracilicaudatus, and P. hermannsburgensis were determined and compared. In total, 12 species of arthropod, 2 cestodes, and 13 nematodes were found. Species richness of parasites was highest in P. hermannsburgensis and lowest in P. desertor. Despite sampling effort, the number parasite species discovered did not reach an asymptote for any of the host species, indicating that the full parasite fauna was not examined. Helminth species richness was highest in the insectivorous P. hermannsburgensis, and lower in the obligate herbivores. The structure of parasite component communities was influenced by ...
