Mesocriconema kirjanovae (Nematoda: Criconematidae) from Southeastern Spain.
An abundant female population of a criconematid species identified as Mesocriconema kirjanovae (Andr ssy, 1962) Loof &De Grisse, 1989 is reported from a natural habitat in southeastern Spain. Measurements and morpho-anatomy obtained with light microscopy and scanning electron microscopy are included and compared with previous data on this species.
متن کاملTaxonomic and molecular identification of mesocriconema and criconemoides species (nematoda: criconematidae).
Populations of Mesocriconema curvatum, M. kirjanovae, M. onoense, M. ornatum, M. sphaerocephala, M. surinamense, M. vadense, M. xenoplax, and Criconemoides informis from different geographical areas in the continental United States were characterized morphologically and molecularly. A new ring nematode from Washington County, Arkansas, is also described and named Mesocriconema ozarkiense n. sp....
متن کاملSpecies Delimitation and Description of Mesocriconema nebraskense n. sp. (Nematoda: Criconematidae), a Morphologically Cryptic, Parthenogenetic Species from North American Grasslands.
Nematode surveys of North American grasslands conducted from 2010 to 2015 frequently recovered a species of criconematid nematode morphologically resembling Mesocriconema curvatum. These specimens were recovered from remnant native prairies in the central tallgrass ecoregion of North America, and not from surrounding agroecosystems. Historical records indicate that M. curvatum is a cosmopolitan...
متن کاملCOI haplotype groups in Mesocriconema (Nematoda: Criconematidae) and their morphospecies associations.
Without applying an a priori bias for species boundaries, specimen identities in the plant-parasitic nematode genus Mesocriconema were evaluated by examining mitochondrial COI nucleotide sequences, morphology, and biogeography. A total of 242 specimens that morphologically conformed to the genus were individually photographed, measured, and amplified by a PCR primer set to preserve the linkage ...
متن کاملInfant botulism in Costa Rica: first report from Central America.
INTRODUCTION Clostridium botulinum is known to cause descending paralysis in infants throughout the world. METHODOLOGY The subject of this study was a three-month-old Costa Rican boy who was hospitalized because of poor suction and feeding, hypotonia, and constipation. Clinical history and physical examination findings suggested infant botulism. Samples were sent to the Winnipeg Public Health...
