Opis:
Arion vulgaris is one of the most important slug pests of crop plants, and is extremely hard to control. We assessed the effectiveness of a slug pellets containing iron phosphate, compared with methiocarb- and metaldehyde-based molluscicides, and of the parasitic nematode P. hermaphrodita contained in the commercial bioproduct Nemaslug. The effect of various doses of these substances and the nematode in reducing slug damage to Chinese cabbage plants was evaluated in laboratory experiments. A reduction in slug numbers and plant damage was obtained following application of the molluscicides, and a reduction in plant damage following application of P. hermaphrodita (immersion of plant roots in the nematode-containing liquid). The results are of great practical significance, because they show that it is possible to reduce the recommended dose of iron phosphate (5 g/m2) by one half. Another important finding is that application of the nematode in the form of root immersion is more effective than spraying. The study demonstrates the usefulness of the nematode and of the iron phosphate molluscicide in protecting plants from A. vulgaris; this is of particular importance for crops on which the application of traditional molluscicides is not possible.

Opis:
The species structure of plant parasitic nematode populations from the rhizosphere of winter wheat grown with crop rotation or in 48-year-old monoculture was analyzed and compared. Dominating species: Bitylenchus dubius, Merlinius microdorus, Paratylenchus neglectus and Heterodera avenae, in monoculture plots, had higher populations than in crop rotation plots. Heterodera avenae eggs and larvae were infected by pathogenic fungi in 68% of the monoculture crops (vs. 65–66% of the cysts from crop rotation), 12–20% of Paratylenchus sp. specimens were colonized by bacteria, mainly by Bacillus penetrans. This study shows nematological changes occurring in long-term wheat breeding, thus providing additional information necessary to fight dangerous viral vectors of the examined cereal.

Opis:
Parasitological examination of 273 pumpkinseed sunfish, caught in the warm water channel at the Dolna Odra Power Plant in Stare Czarnowo near Szczecin was carried out. The total lengths of the fish ranged from 6.8 to 18.1 cm (13.3 cm means), infected fish 9.8 to 17.5 cm. In 48 individuals the presence of nematodes representing 4 species has been found: Schulmanela petruschewskii, Raphidascaris acus, Spiroxys contortus and Contracaecum sp. In total the number of nematodes found was 319, the mean intensity of infection was 6.64. The greatest number of fish infected with parasites was caught in June and April. The most frequently noted has been S. petruschewskii, found in adult forms as well as in larval stage in the liver, intestine, stomach and peritoneum in 40 specimens. In total the number of this nematode found was 305. The least frequent has been S. contortus, rarely found in Poland and for the first time noted in sunfish. Usually one fish was invaded by one species of nematodes.

Opis:
Basing on 43 lectures and reports from the scope of current parasitological and mycological issues presented during the 50th Jubilee Clinical Day of Medical Parasitology (Lodz, 19–20 May 2011), the increasing importance of parasitic diseases and mycoses in medicine was presented. Difficulties in diagnosis and treatment of both imported parasitoses (malaria, intestinal amoebiosis, mansonelliasis) and native parasitoses (toxoplasmosis, toxocariasis, CNS cysticercosis), as well as parasitic invasions coexisting with HIV infection (microsporidiosis) have been emphasized. The possibility of human parasites transmission by vertical route and transfusion has been discussed. The important issue of diagnostic problems in intestinal parasitoses has been addressed, noting the increasing use of immunoenzymatic methods which frequently give false positive results. It was highlighted that coproscopic study is still the reference method for detecting parasitic intestinal infections. The mechanism of the immune reaction induced by intestinal nematodes resulting in, among others, inhibition of the host innate and acquired response was presented. Mycological topics included characteristics of various clinical forms of mycoses (central nervous system, oral cavity and pharynx, paranasal sinuses, nails and skin), still existing problem of antimicrobial susceptibility of fungal strains, diagnostic and therapeutic difficulties of zoonotic mycoses and the importance of environmental factors in pathogenesis of mycosis.

Opis:
Introduction. Parasitic diseases are caused by many species of protozoa, helminths, and arthropods. Parasitosis can be divided into gastrointestinal, tissue and skin diseases and can appear in many different parts of the body. The most common route of transmission is via ingestion. The oral cavity may be a place of colonization for pathogens, resulting in lesion formation. Objective. The aim of the study is to characterise and describe the most important symptoms of parasitic diseases that can be diagnosed during dental examination. Abbreviated description of the state of knowledge. In this study there are discussed diseases caused by the most common protozoa and the nematodes in the oral cavity. Leishmaniasis is caused by Leishmania spp. protozoa, and its most common symptom observed in the oral cavity are painful ulcerations. Toxoplasmosis usually manifests itself through enlargement of the lymph nodes, and the appearance of antibodies in saliva. Entamoeba gingivalis and Trichomonas tenax cause periodontitis chronica and inflammation of the soft tissue. The first of the nematodes, Gongylonema pulchrum, is the reason for, among others, the itchy sensation of a moving foreign body under the mucosa. The most common symptoms of Ancylostoma infection are erythematous papules. Filariae causes an infection that manifests through swelling, abscesses, and painless nodules inside the mouth. Conclusions. New pathogens are emerging worldwide and pose a threat to health. They can manifest their symptoms in the oral cavity, but the diagnosis of the disease by the dentist is not easy and requires interdisciplinary knowledge and consultation.

Opis:
Concentration of glycogen, maltose, and trehalose as well as the activity of hydrolases catabolising them: «-amylases, glucoamylase, maltase, and trehalase were studied during a 48 h infection of Galleria mellonella (Lepidoptera) instar larvae infected with infective Heterorhabditis zealandica (20 nematodes/insect). The content of trehalose in the infected insects during the first day of infection was higher (p < 0.05) than in the controls. The concentration of maltose and glycogen were similar in both groups despite the fact that the activity of all examined o-glycosidases was generally much higher in the infected insects than in the controls.

Opis:
Background. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. Material and methods. Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection activity of SOD was determined in extracts from infected and control insects. Results. The activity of SOD decreased gradually in the controls during the experiment. The activity of enzyme was 2-4-times higher in insects from both infected groups than in the control. During the first 12 h of infection the activity of SOD in insects infected with S. feltiae was higher than in those infected with S. affinis, then the activity of enzyme in the insects of both infected groups stayed at a similar level. A significant decrease of SOD activity in infected was recorded in second day of the infection.

Opis:
Parabronema skrjabini is a spirurid nematode of the family Habronematidae that lives in the abomasum of ruminants such as sheep and goats. The purpose of this study was to investigate the molecular aspects of Parabronema skrjabini in sheep. The worms were collected from sheep in Sanandaj (west of Iran). The first internal transcribed spacer (ITS) of ribosomal DNA (rDNA) nucleotide fragments of Parabronema skrjabini were amplified by polymerase chain reaction (PCR) using two pairs of specific primers (Para-Ir-R and Para-Ir-F). ITS1 homology in the sequence of this study was 69% compared with the sequence data in GenBank. To our knowledge, this is the first study in the world exploring the genetic diversity of P. skrjabini in sheep based on ITS1.

Opis:
Background. The objective of this study was to evaluate the level of roundworm infection in working horses slaughtered for meat. In these horses anthelmintics had not been used. Material and methods. Roundworms were collected post-mortem from small intestines of 83 horses. Results. The mean prevalence of roundworm infection was 12% and intensity 46.7 specimens per horse. Infection was found only in foals; 10 animals were infected (45.4%) among the 22 examined. Due to common occurrence of roundworms (Parascaris equorum) in foals this nematode control should focus particularly on regular anthelmintic treatment of young horses, providing proper hygienic conditions for them and checking the infection level by coproscopical methods.
