Investigation of the gut parasitic community composition in Manis pentadactyla and Manis javanica based on high-throughput amplicon sequencing [PDF]

Frontiers in Veterinary Science
IntroductionThe critically endangered Manis pentadactyla and Manis javanica are increasingly threatened by parasitic infections, with gastrointestinal nematodes and protozoan parasites particularly prominent.MethodsIn this study, 72 fecal samples were ...

Genotypic Analysis of Enterobius vermicularis (Rhabditida: Oxyuridae, Linnaeus, 1758) Among Infected Individuals in Bulgaria: A First Phylogenetic Study [PDF]

Int J Mol Sci
Enterobiasis, caused by the nematode Enterobius vermicularis, remains a widespread public health issue, yet data regarding its genetic structure in Southeast Europe are scarce. This study presents the first molecular and phylogenetic characterization of E. vermicularis isolates from Bulgaria.

Re-assessing the infection strategies of the entomopathogenic nematode Steinernema feltiae (Rhabditidae; Steinernematidae) [PDF]

Parasitology, 2000
Previous studies have indicated that between 60 and 80% of a population of entomopathogenic nematodes do not infect their insect hosts at any one period in time. Two hypotheses explain this behaviour: the first that there is a subpopulation of non-infectious nematodes and the second that the non-infectious group is created by inhibitory cues derived ...

Genome-resolved metagenomics of eukaryotic populations during early colonization of premature infants and in hospital rooms

Microbiome, 2019
Background Fungal infections are a significant cause of mortality and morbidity in hospitalized preterm infants, yet little is known about eukaryotic colonization of infants and of the neonatal intensive care unit as a possible source of colonizing ...

Reproductive status of Tribolium castaneum (Coleoptera: Tenebrionidae) affects its response to infection by Steinernema feltiae (Rhabditida: Steinernematidae) [PDF]

European Journal of Entomology, 2016
Gender-specific reproductive roles are important factors determining sexual dimorphism. Here, we investigate the effects of sex-based differences and reproductive status on the defence of Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae) against infection by Steinernema feltiae (Filipjev, 1934) (Rhabditida: Steinernematidae).

Morphometrics of Infective Juveniles of Steinernema spp. and Heterorhabditis bacteriophora (Nemata: Rhabditida).

Journal of nematology, 2011
Selected morphometrics of Heterorhabditis bacteriophora and seven species of Steinernema from in vivo culture were compared in relation to time of harvest. In addition, five Steinernema species were reared in vitro and their morphometrics were compared with those from in vivo culture.

Comparison of the Galleria baiting technique and a direct extraction method for recovering Steinernema (Nematoda: Rhabditida) infective-stage juveniles from soil [PDF]

Folia Parasitologica, 2000
Forty soil samples from forests and other biotopes in Germany and the Czech Republic were studied for the presence of entomopathogenic nematodes using the Galleria bait method at the same time as a sieving-decanting method for direct extraction of infective-stage juveniles.

Infectivity and Reproduction of Three Heterorhabditid Nematodes (Rhabditida: Heterorhabditidae) in Two Insect Hosts

The Florida Entomologist, 1996
The infectivity, incubation time, and reproduction of three heterorhabditid nematodes, Heterorhabditis sp. Bacardis and FL2122 strains and H. bacteriophora Poinar HP88 strain were studied in two insect hosts, an apionid weevil, Cylas formicarius (F.), and a pyralid moth, Galleria mellonella (L.). Two of the nematodes, Heterorhabditis sp.

Dispersal and Infectivity of the Entomogenous Nematode, Neoaplectana carpocapsae Weiser (Rhabditida: Steinernematidae), in Sand.

Journal of nematology, 2011
Laboratory tests determined the lateral and vertical dispersal patterns of Neoaplectana carpocapsae in sand. In the vertical tests, placement of infective juveniles 15 cm below the sand's surface resulted in the majority (77%) being recovered above the point of placement after 48 h.
