Opis:
The legal process involved in domestic mergers has been considered. European Union regulations were investigated, as well as their direct transposition into Polish legislation. The process itself always consists of managerial, ownership and registration phases. Nevertheless, these phases are not homogeneous and may take different courses depending on the provisions prescribed by the regulations. Several methods of measuring the time to complete mergers have been presented. In the empirical part of the article, the definition of the private time to completion has been adopted which assumes that that the procedure starts by drafting the terms of the merger and ends with the registration of the merger. The influence of different provisions on this measure has been analyzed for the case of Polish domestic mergers. Moreover, statistical reasoning has been conducted for this market showing that several recent legal amendments have shortened the legal procedure involved in consolidation. Finally, some conclusions and suggestions for future research have been presented in the paper.

Opis:
Introduction and objectives: Ixodes ricinus is a tick commonly found on human and animals and of great medical and veterinary importance. The aim of the study was to determine the parameters of different stages of feeding in Ixodes ricinus females. Methods: 229 Ixodes ricinus females were collected from 102 animals – roe deer (Capreolus capreolus) and red deer (Cervus elaphus) culled in southern and south-eastern Poland in 2002. Each female was weighed and the length and width of the scutum as well as the width of the idiosoma were measured. 20 tick females were collected from vegetation growing in the region and analysed in order to compare the changes in the parameters studied to those exhibited by unengorged specimens. Results: Three groups were identified on the basis of female body weight; group I consisted of 52 females in feeding phase I with body weight in the range of 0.0003–0.0043 g (mean 0.0019 g), group II comprised 150 females in feeding phase II with weight in the range of 0.0017–0.3075 g (mean 0.0263 g), and group III consisted of 27 females in feeding phase III with weight in the range of 0.0904–0.3122 g (mean 0.1913 g). Indices characterizing the various feeding phases, such as body index, scutal index, alloscutal index, growth index, engorgement index I and II, and the relative body mass index, were determined. The investigations demonstrated that the values of the morphometric traits in feeding phase I, II and III differe in I. ricinus females. Conclusions: The values of the morphometric features and indices can be helpful in identification of the parasitic stage of I. ricinus females removed from host skin, and assessment of the risk of infection of the host with various parasites injected with tick saliva at the respective feeding phases.

Opis:
Objective. This study presents for the first time a case of Hyalomma excavatum hyperparasitism and an analysis of this phenomenon in terms of its potential role in the biology of ticks and epidemiology of tick-borne diseases. Materials and method. Two partially engorged H. excavatum females, one fully engorged female, and 5 males were collected from a naïve rabbit and placed together in a rearing chamber at a temperature of 25 °C and 75% humidity. Results. 3–4 days after tick detachment from the host’s skin, one partially engorged H. excavatum female was observed attached to the idiosoma of the fully engorged conspecific female. Conclusions. This study and observations of other authors confirm that partially engorged ixodid ticks can re-infest the host, and even co-feeding fully engorged ticks in order to collect the blood meal that is indispensable for important physiological processes. However, inefficient feeding of a partially engorged female on another conspecific female may reduce its reproductive performance and disturb the development of eggs and larvae. It seems that parasitism of a tick on another conspecific specimen, when at least one of them is infected by a microorganism, may be a yet poorly explored route of transmission of pathogens or symbionts between the ticks. Initiation of feeding by a hungry or partially engorged tick on a fully engorged specimen is an attempt to obtain food in the drastic conditions of the absence of a target host. Tick hyperparasitism with concurrent pathogen transmission can contribute to the genospecific diversity of pathogens in vectors and hosts.

Opis:
The Palearctic three-host species Dermacentor reticulatus contributes to the circulation of numerous pathogens in the environment. Reduction of its abundance may therefore decrease the risk of tick-borne diseases in a given area. The aim of the study is to determine the effect of various concentrations of three pyrethroids – deltamethrin (D), cypermethrin (C), and alpha-cypermethrin (AC) on the development of D. reticulatus eggs and larvae. 217 engorged D. reticulatus females were examined in the investigations. After the feeding period, they were sprayed with 0.015625%, 0.03125%, 0.0625%, and 0.125% solutions of D, C, and AC, and kept at a temperature of 25oC and 90% relative humidity throughout the preoviposition and oviposition periods. Eggs laid by females were kept in the same conditions until larval hatch. Based on the results obtained, parameters of the course of maturation and oviposition, as well as parameters of embryonic development, were determined. The investigations showed that the pyrethroids tested prolonged the egg maturation period, reduced the number and weight of eggs, and caused disturbances in embryogenesis in D. reticulatus. Upon treatment with as little as 0.015625% AC, larvae did not develop and all eggs died 1–2 days after oviposition. C led to a decreased percentage of normal larval hatch – 31.96%, 15.51% and 12.5%, respectively, after using three increasing concentrations (control 98.15%), and a high rate of egg and embryo mortality. The least detrimental effect on the D. reticulatus maturation and embryonic periods was exerted by deltamethrin (82.74%, 84.37% and 16.80% of normal larvae in treatment with the three concentrations). Morphological anomalies were observed in larvae during the experimental period. AC appeared to have the most toxic effect during the maturity and egg development periods, while C exhibited lower toxicity. Application of these pyrethroids in engorged D. reticulatus females exerts distant effects that lead to substantial reduction of tick offspring abundance.

Opis:
Introduction. The three-host Dermacentor reticulatus tick transmits many pathogens, which are introduced into the host with saliva during feeding. Material and methods. The aim of present study was to analyse the behaviour of males of this species on the host in homogeneous sex groups comprising 15 (group I) and 30 (group II) male specimens and in a mixed group composed of 15 males and 15 females (group III). Results. Although the dynamics of attachment of the males to host skin slightly differed between these three groups, there was no statistically significant difference in the duration of the attachment process. The duration of host attachment of the males in groups I, II, and III at 18 ± 2 °C and 50 ± 2% RH was 2.43 ± 2.46, 7.75 ± 11.85, and 9.07 ± 10.97 days, respectively. After 7–9-day feeding, the male engorgement weight (MEW) was similar, regardless of the size of the group and the presence or absence of females on the host. Tick males ingest a small amount of host blood. The value of MEW in the three groups did not differ statistically from the weight of unengorged specimens. Conclusions. The host feeding behaviour of D. reticulatus males and their effective feeding suggest that they may play a role in transmission of pathogens and non-pathogenic microorganisms with tick saliva during blood meal ingestion. Clinical and laboratory diagnostics of human and animal tick-borne diseases as well as epidemiological studies should consider the possibility of pathogen transmission by males of metastriata ticks, which feed on the host for several days.

Opis:
For the first time in the world literature, the presented study describes oral-anal contact between two sympatric Ixodes ricinus and Dermacentor reticulatus ticks, which are the vectors of many pathogens in Europe. Among the specimens collected in nature, an I. ricinus male was found with the hypostome and chelicerae inserted in the anal aperture of a D. reticulatus female. Given the biological and physiological traits of both species and microorganisms colonising these arthropods, it seems that the interspecific oral-anal contacts between ticks may be an unknown alternative route of transmission of pathogenic and symbiotic microorganisms present in ticks’ alimentary tract, faeces, body surface, and in the haemolymph and organs, taking place when the male’s mouthparts are inserted into the female’s body. The authors suggest that interspecific contacts between ticks in natural conditions can contribute to the spread of some microorganisms among different tick species and their hosts.
