The objective of the studies was to determine the extensiveness and intensity of mallophagian lice invasion in guinea pigs in different laboratory animal husbandries and control of the invasion with preparates used to eliminate ectoparasites in domestic animals. A total of 1550 guinea pigs from 4 husbandries have been examined. In three husbandries all the animals were infested by mallophagian lice. The most prevalent appeared to be Gliricola porcelli (100%) then Gyropus ovalis (90%) and the less prevalent Trimenopon hispidum (40%). The intensity of invasion with individual species of mallophagian lice was similar because G. porcelli infected guinea pigs in a greater number — a mean number 456 parasites/animal, C. ovalis — 32 and T. hispidum — 37. Biocid 0.1%, Insectin 0.5%, Ivomec 200 µg and 400 µg and Pularyl applied according to the prescriptions of producers appeared to be very effective in the control of mallophagian infection excep of Pularyl in spray which was completely ineffective. Biocid 0.1% and Insectin 0.5% in spray used twice at 2 week interval enabled a total eradication of mallophagian lice invasion in guinea pig husbandries.
The following types of teratology were found in the collection of 1278 individuals of Mallophaga coming from the birds of South Africa origin: deformity clypeus in Quadraceps kilimandjarensis (KELL.) from Stephanibyx coronatus (BURCH.), partial atrophy of one of the antennae of two males Q. kilimandjarensis and abdomen plates deformity of two females Q. kilimandjarensis, in male and female Quadraceps chorleyi TIMM. from Hoplopterus armatus (BURCH.), in female Saemundssonia africana TIMM. from Stephanibyx coronatus (BODD.) and male Plegadiphilus threskiomis (BEDF.) from Threskiornis aethiopicus (LATH.) the only representative of Amblycera (the other teratology belonged to Ischnocera suborder). Generally teratology was found in 0.70% of the collection.
The variability of metric characters of 7 examined species to the biting lice, typical for the pheasants, totalled 2-6% for imagines. In some species the coefficients of variability for the measurements of thorax and abdomen reached value of 10%. As a rule, the head dimensions as well as the total lenght of three species had the lowest (to 3%) variability. The nymphs were characterized by the higher coefficients of variability of all examined characters, though also the lowest (3-8%) values were noted for the head dimensions whereas the highest (to 19%) ones for abdomen width. Such high values are probably associated with extending of the abdomen which is slightly sclerotized in the nymphs.
Bodies of nymphs and imagines of Docophoroides brevis (Docophoroididae), parasite of Diomedea exulans, were studied unter light and scanning microscopes. Developmental features of nymphs corresponded with similar features of other Philopteroidea. In adults type and distribution of sensillae were similar to other Ischnocera. Structures pointing to parasite's adaptation to holding itself on host's feathers, were distinguished. They were, besides characteristic claws, the mouth apparatus, groups of hooked processes on tibiae of the II and III pairs of legs, and sculpture of roundish fields on the sides of abdomen sternites. In the shape of male's genital apparatus, protruding to the outside of terminal sclerite, structures helping both partners to contact during copulation were discerned.
Biting lice were collected (mostly in Poland) from 15 species of Charadriiformes (Charadriidae, Scolopacidae, Laridae and Alcidae). We tried to determine the frequency of occurrence of particular species of Mallophaga. Quantitative and qualitative analysis of co-occurrence of external parasites (Mallophaga and some Astigmata) was also carried out. We stated that inter-species competition is not significant in shaping the fauna of external parasites of Charadriiformes.

After examination of 202 fallow deers, in 15 of them D. meyeri was founded. Prevalence amounted to 7% intensity ca. 5.5 specimens.
A total of 356 Dama dama individuals (about 20% of the population inhabiting Pomerania, Poland) were examined over a period of 6 years (1996-2001). The fallow deer were found to act as hosts for 8 parasitic arthropod species belonging to 4 orders: Diptera (Lipoptena cervi), Mallophaga (Damalinia meyeri), Anoplura (Solenopotes burmeisteri) and Acari (Ixodes ricinus, Dermacentor reticulatus, Sarcoptes scabiei, Chorioptes texanus, Demodex kutzeri). The extent of infestation was species-dependent; the highest prevalence (76%) was typical of L. cervi, followed by I. ricinus (29%) and D. meyeri (7%). On the other hand, the extent of infestation of small epidermal Acari was generally low, e.g., the prevalence of C. texanus did not exceed 1%. Despite the relatively high prevalences, the infestations were symptomless.
Knowledge of morphometric characteristics of Heterodoxus spiniger was widened on the basis of material collected from dog (Canis familiaris) from India. Study, mostly by scanning electron microscope, concerned the males, females and nymphs of H.spiniger. The functional role of some elements, particularly observed surface ultrastructures, has been pointed out. The differences between postembrional stages were determined as well as literature data on H.spiniger were critically analysed.
During the last century the recorded parasite fauna of Bison bonasus includes 88 species. These are 22 species of protozoa, 4 trematode species, 4 cestode species, 43 nematode species, 7 mites, 4 Ixodidae ticks, 1 Mallophaga species, 1 Anoplura, and 2 Hippoboscidae flies. There are few monoxenous parasites, the majority of parasites are typical for other Bovidae and Cervidae species and many are newly acquired from Cervidae. This is an evident increased trend in the parasite species richness, in both the prevalence and intensity of infections, which is associated with the bison population size, host status (captive breeding or free-ranging) and the possibility of contact with other ruminant species. In light of the changes to parasite species richness during the last decades, special emphasis shall be given to new parasite species reported in European bison, their pathogenicity and potential implications for conservation.
On the basis of morphological examinations of the head of Bovicola caprae, Cervicola meyeri and C. tibialis, carried out in the scaning electron microscope, the species descriptions received up to now, were supplemented with new characters. An attention has been paid to rather primitive type of antennal sesilla coeloconica (with developed cone) as well as the lack of accompanying pore organs, characteristic also of other Ischnocera.
