The article examines the aspects of dependence of some leaf mine characters. The correlation between the deposition of frass and the morphological type of the leaf mine suggests that ecological adaptations associated with the drying of the frass are diverse, depending on the morphological type the leaf mine. The colour of frass has little in common with the systematic group (i.e., family) of host plants. Black frass is characteristic and predominant among miners of any host plant family. The study also suggests that the location of frass is at least partially associated with different morphological types of leaf mines. When summarising the results of the study, it can be stated that the filling of the initial part of the mine with frass is related to the filling of the whole gallery of the leaf mine.

This study provides updated summarised data on host-plant preferences and mining seasons of the Nepticulidae of the Lithuanian fauna. It revealed that the Lithuanian Nepticulidae are trophically associated with 34 genera and 14 families of host plants. Four of these host-plant families stand out in a number of mining Nepticulidae species and all together host about 80% of the Lithuanian Nepticulidae. As regards feeding specialisation, the fauna of the Lithuanian Nepticulidae consists of three constituents: monophagous species (about 44%), narrow oligophagous species (about 48%), and true oligophagous species (about 8%). There are two distinctive peaks of mining: the summer peak from mid-June until mid-July and the autumn peak from early September until mid-October, when most species mine simultaneously.

Bacteria of the genus Leptospira can cause widespread and potentially lethal bacterial zoonosis called leptospirosis. Considered a neglected tropical zoonotic disease, leptospirosis was recognized as a global public health problem due to its increasing prevalence in developing and developed countries. This review focused on the current knowledge on leptospiral infection, classification, epidemiology, and detection methods. We are also reviewing the data on the study of Leptospira in Lithuania available in the literature.

This study identifies major diagnostic morphological and some biological characters of leaf mines of Nepticulidae and provides a pictorial guide to the morphological characters with detection frequencies for each character. Drawing on detection frequencies, it establishes that the most typical leaf mine of Nepticulidae belongs to one of the two morphological types of (1) serpentine, gradually slightly widening and (2) serpentine, strongly widening, and that it can be characterised by black or brownish black frass accumulated in a solid line or band with wide clear margins of the gallery. Such a typical leaf mine is sinuous or contorted and, as a rule, found on Rosaceae or Betulaceae; the feeding larva is yellow.

This work aimed to study the morphofunctional changes in the resistive region of the pulmonary microcirculatory bed in ovalbumin- sensitised guinea pigs. Using histological, morphometric, and statistical methods, we studied the lungs of 48 male guinea pigs in conditions of the experimental allergic inflammatory process. To assess the structural and functional state of medium (51– 125 μm) and small (25–50 μm) arterioles, the outer and inner diameters, the thickness of the tunica media, and the Kernogan index were determined. The most pronounced changes, such as thickening of their walls and narrowing of the lumen in the late stages of the allergic inflammatory process, consisted in the restructuring of medium arterioles. Compared to control animals, the inner diameter of the medium arterioles decreased three times (p*/**<0.05) in experimental group 4; the thickness of the tunica media of medium arterioles increased two times (p*/**<0.05) in experimental group 3. These changes are the result of the increasing tone and hypertrophy of the smooth muscles of the tunica media and the decreasing capacity of arterioles as evidenced by a statistically significant increase of the Kernogan index-indicated hypertrophy and the increasing tone of the smooth muscles of the tunica media and decreasing vascular throughput.

The research objective of this work was to investigate and study details of the CRISPR adaptation process in several different CRISPR-Cas systems as well as use genome-wide CRISPR screening to elucidate cell-intermedilysin interactions. The results of this study showed that Cas1-Cas2 complex from S. thermophilus CRISPR4-Cas system forms a complex that integrates prespacers into the CRISPR array. DnaQ domain fused to Cas2 in this system is a 3’–5’ DNA exonuclease. DnaQ domain is dispensable for spacer integration; however, it serves to trim back overextended 3’ overhangs of the prespacer. Cas1, Cas2, and Csn2 proteins from S. thermophilus CRISPR3-Cas system form at least three different complexes, which interact with Cas9 from the same system via the DNA tether. The identified complexes from CRISPR3-Cas system represent a spacer capture step of the new spacer acquisition process, as they harbour spacer length DNA in their assemblies. Genome-wide CRISPR screening can reveal novel fundamental biological pathways in the membrane composition and lipid metabolism when used in concert with membrane targeting toxins. Intermedilysin has many more dependency factors than previously known CD59 and cholesterol. Among them are heparan sulfates, glucosylceramides, and many other protein or lipid glycosylation factors. ILY can be inhibited by heparin or the removal of heparan sulfates from cells using bacterial heparinases.

Sand is one of children’s favourite playing objects, thus sandboxes can be found in almost every playground next to apartment buildings. However, sand is also an excellent medium for the proliferation of microorganisms due to its favourable organic matter content, relative humidity, and pH. Therefore, children playing in sandboxes where toys have been left behind are at risk of becoming infected with microorganisms that cause infectious diseases. The main infectious pathogens Esheriahia coli, Staphylococcus aureus, Salmonella spp. and Enterococcus spp. were analysed in the sandboxes of children’s playgrounds set up in the yards of apartment buildings. The test material came from the surfaces of the toys left in the sand, the edges of the sandboxes, and sand samples collected in autumn and winter. Enterococcus spp., Salmonella spp. and E. coli were detected in the samples from the edges of sandboxes and surfaces of sand-covered toys and surfaces collected in autumn. S. aureus (on the surface of the toys left in sand) and E. coli were detected in the samples collected from the surfaces of toys and sandboxes in winter. During the study, no infectious agents were detected in the sand samples.

In European countries, hunting of wildlife is regulated by various directives. However, illegal hunting activities are becoming more common. To deal with wildlife crime cases, it becomes necessary to select the best molecular markers for the analysis of animal sex, species, and relationships identification. This study investigated potential markers within chromosomal and mitochondrial DNA (mtDNA) for animal forensics. By applying markers targeting nuclear DNA and mitochondrial DNA (the cytochrome b gene, hypervariable displacement loop (D-Loop) region, SRY and AMEL genes), the suspected illegal hunting cases were solved by the identification of wild species and sex. Currently, molecular forensic techniques are necessary before conclusions of its validation in forensic investigations.

During the present investigation, 23 species of fish in Lithuanian inner waters were examined for helminth parasites. Of these, 63 taxa of helminths – 56 taxa of Plathyhelminthes, five of Nematoda, and two of Acanthocephales – were found. Monogenea Gyrodactylus truttae was registered in Lithuania for the first time. Metacercariae of flukes Diplostomum sp., Posthodiplostomum cuticula, and Tylodelphys clavata were found in the highest number of host species: 16, 11, and 12, respectively. A generalized linear mixed model (GLMM) shows that six cyprinid species – Rutilus rutilus, Scardinius erythrophthalmus, Leuciscus leuciscus, Squalius cephalus, Blicca bjoerkna, and Abramis brama – have greater probability of infection with Diplostomum sp. metacercariae. The GLMM also shows that the random effect (the type of Lithuanian inner water body) was statistically significant. Differences in the prevalence of infection with Diplostomum sp., P. cuticula, and T. clavata metacercariae in different water body types were established for some fish species.
