The LSU–D2D3 segment and the ITS–rDNA region of this species were amplified and sequenced. The morphological characters and molecular phylogenetic analyses confirmed that this is a new species of the genus Pratylenchus in Vietnam.

Abstract Pseudacrobeles (Pseudacrobeles) curvatus sp. n. was collected from potato fields in Gyeongsangnam-do, South Korea. The new species shares morphological characters typical of the genus Pseudacrobeles, including three lateral incisures that fade posteriorly near the phasmid openings. The new species differs from other Pseudacrobeles species by its smaller body size and a comparatively shorter corpus relative to the isthmus length. In this study, we provide a comparison of morphometrics

Two New Species of Pristionchus (Nematoda: Diplogastridae) from Taiwan and the Definition of the pacificus Species-Complex Sensu Stricto

Asia has emerged as a hotspot of Pristionchus speciation and recent samplings have therefore focused on Islands and mainland settings in East Asia. Here, we describe in a series of three publications the results of our sampling efforts in Taiwan, Japan, and Hongkong in 2016 and 2017. We describe a total of nine new species that cover different phylogenetic species-complexes of the Pristionchus genus. In this first publication, we describe two new species, Pristionchus sikae sp. n. and Pristionchus

A new species, the third one from Vietnam, of the genus Aporcelinus is described from natural areas. Aporcelinus falcicaudatus sp. n. is characterized by its 1.28 to 1.63 mm long body, lip region offset by weak constriction and 16 to 18 mm broad, odontostyle 18 to 21 mm at its ventral side, neck 354 to 406 mm long, uterus tripartite and 61 to 95 mm long, V = 50 to 55, tail strongly recurved dorsad and conical (23–31 mm, c = 43–58, c9 = 0.7–0.9) with finely rounded tip

Samplings of Millipedes in Japan and Scarab Beetles in Hong Kong result in five new Species of Pristionchus (Nematoda: Diplogastridae)

The authors describe five new species of Pristionchus from Japan and Hongkong. Scarab beetle samplings in Hongkong identified P. hongkongensis sp. n. and P. neolucani sp. n., representing the first beetle-associated Pristionchus species from China. Surprisingly, samplings of millipedes in Japan revealed a previously unknown association of Pristionchus nematodes with these arthropods. Specifically, the authors found three previously known Pristionchus species, P. arcanus, P. entomophagus, and P

CURRENT CHALLENGES OF VETERINARY MICROBIOLOGICAL DIAGNOSTICS CONCERNING THE SUSCEPTIBILITY OF STAPHYLOCOCCI TO ANTIBIOTICS

Staphylococci are pathogenic bacteria often isolated from clinical material obtained from animals. Unlike in human medicine, in veterinary sciences various species of coagulase-positive staphylococci have been isolated from clinical specimens. In addition to Staphylococcus aureus and Staphylococcus pseudintermedius, other species are also often identified. Recently, the taxonomy of staphylococci has been updated, therefore, it is now important to recognize also the new species. Currently

), umbu (Spondias tuberosa), and acerola (Malpighia glabra) (Trindade et al. 2002; Da Silva et al. 2005; Grondin et al. 2015). The Amazonian rainforest’s environmental characteristics suggest the possibility of finding diverse yeast communities, including new species or strains with new characteristics of biotechnological interest (Morais et al. 1995; Da Silva et al. 2005). Yeasts represent a promising source for obtaining microbial enzymes (Trindade et al. 2002; Da Silva et al. 2005; Raveendran et al

yet. Herein, the descriptions of two new species of predatory soil nematodes of the genus Parkellus are provided. Jairajpuri et al. (2001) established the monotypic genus Parkellus for the new species P. parkus collected in Korea from forest soil surrounding the roots of Euonymus oxyphyllus Miq. The main feature that distinguished the newly described genus Parkellus from the morphologically very similar Coomansus (Jairajpuri and Khan, 1977) is the location of dorsal tooth in the posterior half of

attributable to unreasonable antifungal prevention (Basetti et al. 2009; Gołaś et al. 2014). C. glabrata candidemias are on the increase (Quindós 2014). In ten years (since 1989) C. glabrata candidemias have increased from the fourth to the second most common cause of ICU infections (Lockhart et al. 2012). Nowadays, the C. glabrata species complex has been identified including three closely related new species: C. glabrata sensu stricto, C. nivariensis, and C. bracarensis (Alcoba-Flórez et al. 2005

Cryphodera gayae n. sp. (Nematoda: Heteroderidae), from root of Lagerstroemia indica in Korea

Cryphodera (Colbran, 1966) is a thick-cuticled non-cyst forming nematodes in the group of Heteroderinae. There are seven species of Cryphodera, all parasitic to various species of trees; they are C. brinkmani (Karssen and Van Aelst, 1999), C. coxi, C. nothophagi, C. podocarpi (Wouts, 1973), C. eucalypti (Colbran, 1966), C. kalesari (Bajaj et al., 1989) and C. sinensis (Zhuo et al., 2014). During a survey of plant-parasitic nematodes in Korea, a new species of the non-cyst forming nematode was
