Seven- to eight-week-old rabbits were infected with Eimeria intestinalis Cheissin, 1948, a highly immunogenic coccidium, or Eimeria flavescens Marotel et Guilhon, 1941, which is weakly immunogenic. Immune response was investigated at 7, 14 and 21 days post inoculation (DPI). The level of serum immunoglobulins, lymphocyte proliferation stimulated by parasite antigens and weight of mesenteric lymph nodes (MLN) showed similar dynamics in rabbits inoculated with both coccidia species. The amount of serum IgG and IgM, but not IgA, was increased from 14 DPI. The lymphocytes from MLN of infected animals significantly reacted to stimulation with...

Haemosporidian infections in captive exotic glossy starling Lamprotornis chalybaeus in Hong Kong

Ilan Paperna, Paolo Martelli

Folia Parasitologica 55[1] 7-12 (2008) | 10.14411/fp.2008.002

A greater blue-eared glossy starling Lamprotornis chalybaeus Ehrenburg from a large flight aviary in Hong Kong was found on post mortem to be infected with Plasmodium octamerium Manwell, 1968, Plasmodium cf. relictum (Grassi et Feletti, 1891) and Haemoproteus cf. pastoris Mello, 1935. Descriptions of their morphology are provided as none of the examined parasites fully concord with their type (or neotype) material descriptions. Plasmodium octamerium has been recorded in avian hosts from geographically distant locations, suggesting that infection in imported hosts may persist in a chronic state for a...

Rodents as intermediate hosts of Hepatozoon ayorgbor (Apicomplexa: Adeleina: Hepatozoidae) from the African ball python, Python regius?

Folia Parasitologica 55[1] 13-16 (2008) | 10.14411/fp.2008.003

Two experimental trials were performed to elucidate the role of rodents in the life cycle of Hepatozoon species using snakes as intermediate hosts. In one trial, two ball pythons, Python regius Shaw, 1802 were force fed livers of laboratory mice previously inoculated with sporocysts of Hepatozoon ayorgbor Sloboda, Kamler, Bulantová, Votýpka et Modrý, 2007. Transmission was successful in these experimentally infected snakes as evidenced by the appearance of intraerythrocytic gamonts, which persisted until the end of trial, 12 months after inoculation. Developmental stages of haemogregarines were not observed in histological sections...

Tapeworms (Cestoda: Proteocephalidea) of firewood catfish Sorubimichthys planiceps (Siluriformes: Pimelodidae) from the Amazon River

Folia Parasitologica 55[1] 17-28 (2008) | 10.14411/fp.2008.004

A survey of proteocephalidean cestodes found in the firewood catfish Sorubimichthys planiceps (Spix et Agassiz) from the Amazon River is provided. The following taxa parasitic in S. planiceps are redescribed on the basis of their type specimens and material collected recently in the Amazon River, near the type localities in Brazil, and in Iquitos, Peru: Monticellia lenha Woodland, 1933; Nomimoscolex lenha (Woodland, 1933) (syn. Proteocephalus lenha Woodland, 1933); and Monticellia megacephala Woodland, 1934, for which a new genus, Lenhataenia, is proposed, with L. megacephala (Woodland, 1934)...

Taxonomical study into two new species of Philometra (Nematoda: Philometridae) previously identified as Philometra lateolabracis (Yamaguti, 1935)

Folia Parasitologica 55[1] 29-41 (2008) | 10.14411/fp.2008.005

Males of the nematode Philometra lateolabracis (Yamaguti, 1935), the type species of the genus Philometra Costa, 1845, were discovered for the first time in gonads of its type host, the Japanese seaperch, Lateolabrax japonicus (Cuvier). Morphological comparisons carried out between the collected male and female P. lateolabracis with the male and female philometrid nematodes previously reported as P. lateolabracis infecting chicken grunt, Parapristipoma trilineatum (Thunberg), and red sea bream, Pagrus major (Temminck et Schlegel), revealed that the latter represent two new species, Philometra isaki...

A standardised terminology of the embryonic envelopes and associated developmental stages of tapeworms (Platyhelminthes: Cestoda)

David Bruce Conn, Zdzisław Świderski

Folia Parasitologica 55[1] 42-52 (2008) | 10.14411/fp.2008.006

Over the past 40 years, much has been published on the ultrastructure and cellular development of embryonic structures in a wide range of cestodes. However, the literature contains many discrepancies in both terminology and interpretations because of the facts that these organisms are phylogenetically diverse within their respective orders and families, the habitats that affect embryonic envelope structure are diverse, and the work has been done in various laboratories around the world. This review and synthesis was initiated by a working group of biologists from around the world convened at the Fifth International Workshop on Cestode Systematics and...

Crustacean-acanthocephalan interaction and host cell-mediated immunity: parasite encapsulation and melanization

Bahram Sayyaf Dezfuli, Edi Simoni, Laura Duclos, Emanuele Rossetti

Folia Parasitologica 55[1] 53-59 (2008) | 10.14411/fp.2008.007

Host-parasite interactions of Pomphorhynchus laevis (Müller, 1776) in naturally infected amphipod, Echinogammarus stammeri (Karaman), from the Brenta River (northern Italy) are described. A fully developed acanthocephalan larva occupies a large portion of an amphipod's haemocoelic space; thus, the parasite frequently induces displacement of host digestive tract and other internal organs. However, no apparent damage to the host's internal structures was observed. Within the haemocoel of E. stammeri, each larva of P. laevis is surrounded with a membranous layer, formed by microvilli, which maintains intimate contact with the...

The genus Hyalomma Koch, 1844. IV. Redescription of all parasitic stages of H. (Euhyalomma) lusitanicum Koch, 1844 and the adults of H. (E.) franchinii Tonelli Rondelli, 1932 (Acari: Ixodidae) with a first description of its immature stages

Hyalomma (Euhyalomma) lusitanicum Koch, 1844 and Hyalomma (Euhyalomma) franchinii Tonelli Rondelli, 1932 are amongst the most poorly studied of those species within the genus Hyalomma Koch, 1844 that are restricted to the Mediterranean region. No comprehensive morphological study has been done to date, and the immature stages of H. (E.) franchinii have not been described. Here all the parasitic stages of H. (E.) lusitanicum and the adults of H. (E.) franchinii are redescribed, and the immature stages of the latter species are described for...

A diagnostic assay based on variable intergenic region distinguishes between Leishmania donovani and Leishmania infantum

Eva Chocholová, Milan Jirků, Julius Lukeš

Folia Parasitologica 55[1] 75-78 (2008) | 10.14411/fp.2008.010

We have developed a PCR assay that in a single reaction distinguishes between Leishmania infantum and Leishmania donovani strains on the basis of different size of the amplicon. The targeted intergenic region between putative biopterin transporter and nucleotide binding protein on chromosome 35 is highly variable, species-specific and can be amplified from clinical samples. Based on the assay, five tested Leishmania archibaldi and L. infantum strains from the Sudan and Ethiopia clearly belong to L. donovani, which is in accordance with a recent multifactorial analysis of these strains. The nucleotide sequence reported...
