The present article is concerned with the study of glial fibrillary acidic protein (GFAP) level in the blood serum of pregnant women with posttrauma brain injury syndrome (postTBI syndrome) as the marker of hematoencephalic barrier status and predictor of obstetric and perinatal complications development., Irina Vasilivna Tsyganenko, Vasil Vasilyovich Simrok, Katerina Sergiivna Ruban, and Literatura
To investigate the transmission of species of Cryptosporidium Tyzzer, 1907 in Timis County, Romania, 48 isolates of Cryptosporidium coccidia from 11 children, 29 calves and eight pigs were characterised by molecular analysis of two loci (SSU rRNA and 60-kDa glycoprotein gene). Overall, 22 isolates were amplified and sequence analyses revealed that all isolates were Cryptosporidium parvum Tyzzer, 1912. Two subtype families were identified, IIa and IId. Subtype IIdA22G1 (n = 4) was the single C. parvum subtype found in children. Subtypes found in calves included IIdA27G1 (n = 8), a novel subtype, IIdA25G1 (n = 5), IIdA22G1 (n = 2), IIdA21G1a (n = 1), and IIaA16G1R1 (n = 1). Subtype IIdA26G1 was found in a pig. These results were significantly different from previous Romanian reports, as the five subtypes of family IId identified in this study were never identified previously in this country. Thus, cattle may be a source of Cryptosporidium infections for humans and the transmission dynamics of C. parvum in Romania is more complex than previously believed., Patrícia Manuela Vieira, Narcisa Mederle, Maria Luísa Lobo, Kálmán Imre, Ovidiu Mederle, Lihua Xiao, Gheorghe Darabus, Olga Matos., and Obsahuje bibliografii
Species of the genus Lamellodiscus Johnston et Tiegs, 1922 (Monogenea: Diplectanidae) are characterised by a complex haptor bearing many different attachment elements: two pairs of main hooks joined by medial bars, 14 peripheral marginal hooks and one or two lamellodiscs, formed by several overlapping sclerotised plates (lamellae). These haptoral structures appear gradually during parasite development and, therefore, attachment strategies vary with developmental stage. The main aim of this work was to study the developmental changes of Lamellodiscus theroni Amine, Euzet et Kechemir-Issad, 2007 under experimental conditions, with special attention to the gradual variations in attachment strategies and the pathological implications. Throughout the gradual development of the sclerotised structures, six developmental phases were distinguished in L. theroni: phase I, with only 14 peripheral marginal hooks; phase II, with main hooks (ventral and dorsal) formed; phase III, with ventral bar formed; phase IV, with dorsal bars formed; phase V, with dorsal and ventral lamellodiscs formed; and phase VI, adult stage with male copulatory organ formed. During development, parasites attach to different parts of the first and secondary gill lamellae and the mode of attachment changes from unspecific stage, i.e. based on piercing any flat gill tissue in the early stages, through an intermediate stage when ventral and dorsal main hooks are completely functional and parasites become restricted to the interlamellar space, and finally to the definitive adult attachment stage when lamellodiscs are fully developed. The timing of key events in the development of L. theroni was used to establish adequate intervals for anthelmintic drug administration., Neus Sánchez-García, Juan A. Raga, Francisco E.

Cercariae and metacercariae of three species of the Microphallidae Travassos, 1920 were found in snails and crustaceans from tributaries of the Brisbane River, Queensland, Australia. Specimens of Maritrema brevisacciferum Shimazu et Pearson, 1991 and Microphallus minutus Johnston, 1948, which have previously been reported in Queensland, were found as cercariae in the tateid gastropod Posticobia brazieri (Smith) and as metacercariae of M. brevisacciferum in the atyid shrimp Caridina indistincta Calman and of M. minutus in the parastacid crayfish Cherax dispar Reik. Combined analysis of morphological and molecular data, based on newly generated ITS2 and partial 28S rDNA data, linked cercariae and metacercariae for both species. This is the first report of the first intermediate hosts of M. brevisacciferum and M. minutus. Infections of another unidentified microphallid metacercariae, Microphallidae gen. sp., were found in P. brazieri and C. indistincta. The sequences of metacercarial isolates from both hosts were identical. The data on the Microphallidae from Australia and species that develop in freshwater invertebrates were examined in detail., Olena Kudlai, Scott C. Cutmore, Thomas H. Cribb., and Obsahuje bibliografii
