Age-related dynamics of protozoan and helminth infections in the red-legged partridge, Alectoris rufa, were studied in an intensive breeding aviary in the Czech Republic before releasing birds for hunting purposes. Pooled fecal samples (n = 900) were examined over 3 rearing seasons (2012-2014). A total of 4 protozoan species, Cryptosporidium baileyi, Cryptosporidium meleagridis, Eimeria kofoidi, and Eimeria legionensis, and 4 helminths, Capillaria phasianina, Eucoleus perforans, Heterakis gallinarum, and Syngamus trachea, was found. The most common parasite was S. trachea (prevalence 20-26%) in dead birds (n = 99), which represents a high risk for breeders. Co-occurrence of protozoans and helminths indicated similarities in infection dynamics throughout the 3 breeding seasons. Mixed infections of Cryptosporidium baileyi and C. meleagridis with other parasitic species are reported for the first time. Our findings provide new insights into breeding of A. rufa and may help to improve the efficacy of disease control strategies and prevention, especially with the potential for spreading of parasitic infections to wildlife through released birds into open areas.

Recent examinations of spirurid nematodes (Spirurida) from deep-sea or coral reef marine fishes off New Caledonia, collected in the years 2006-2009, revealed the presence of the following five species: Ichthyofilaroides novaecaledoniensis (Moravec et Justine, 2009) n. gen., n. comb. (transferred from Ichthyofilaria Yamaguti, 1935) (females) (Guyanemidae) from the deep-sea fish Hoplichthys citrinus (Hoplichthyidae, Scorpaeniformes), Philometra sp. (male fourth-stage larva and mature female) (Philometridae) from Epinephelus maculatus (Serranidae, Perciformes), Ascarophis (Dentiascarophis) adioryx Machida, 1981 (female) (Cystidicolidae) from Sargocentron spiniferum (Holocentridae, Beryciformes), Ascarophis (Ascarophis) nasonis Machida, 1981 (males and females) from Naso lituratus and N. unicornis (Acanthuridae, Perciformes), and Ascarophisnema tridentatum Moravec et Justine, 2010 (female) from Gymnocranius grandoculis (Lethrinidae, Perciformes). Two species, I. novaecaledoniensis and A. nasonis, are redescribed based on light microscopical (LM) and scanning electron microscopical (SEM) examinations, the latter used in these species for the first time. Morphological data on the specimen of A. tridentatum from the new host species are provided. Philometra sp. (from E. maculatus) most probably represents a new gonad-infecting species of this genus. The newly established genus Ichthyofilaroides n. gen. is characterized mainly by the presence of a small buccal capsule and by the number and distribution of cephalic papillae in the female; it is the sixth genus in the Guyanemidae.

Serratospiculiasis is a parasitic disease caused by filariid nematodes of the genus Serratospiculum that parasitise the air sacs of various species of falcons, bald eagles and Cooper's hawks around the world. An infection with Serratospiculum was recently confirmed in a nonspecific host, the great tit, in Slovakia. Parasitic material from this host was fixed for molecular analysis. Nematode found in the air sacs from a captive-bred gyrfalcon was also stored. Analysis of small subunit (18S) ribosomal DNA (18S rDNA) gene indicated that sequences from Serratospiculum sp. and Serratospiculoides amaculata were closely related to a reference sequence from Serratospiculum tendo, in agreement with morphology. This study is the first to generate molecular data and infer the phylogenetic position of S. amaculata as the first representative of the genus Serratospiculoides.

Three adult nematode specimens, all ovigerous females belonging to the family Cystidicolidae Skryabin, 1946, were found for the first time in the subcutaneous tissue around the eye of the captive porcupinefish Diodon nichthemerus Cuvier at a public aquarium in Osaka, Japan. Because no male was available, these could not be identified to the genus and species. This case highlights the risk of parasitism in aquaculture puffer fish, as these may ingest small shrimp, which probably act as intermediate hosts for the nematode.

Based on light and scanning electron microscopical studies, three adult spirurid nematode species, Camallanus (Zeylanema) ctenopomae Vassiliadès & Petter, 1972, Paracamallanus cyathopharynx (Baylis, 1923) (both Camallanidae) and Spinitectus polli Campana-Rouget, 1961 (Cystidicolidae), are redescribed from specimens collected in fishes of the Okavango River, Botswana: C. (Z.) ctenopomae from Ctenopoma sp. (Anabantidae), P. cyathopharynx from Clarias stappersi Boulenger, C. theodorae Weber (both new hosts, Clariidae) and C. gariepinus (Burchell), as well as S. polli from Synodontis nigromaculatus Boulenger (new host, Mochokidae). Moreover, spirurid larvae of an additional three species were found in fishes from the same locality: Rhabdochona paski Baylis, 1928 fourth-stage larva (Rhabdochonidae) in S. nigromaculatus (Mochokidae), Physalopteridae gen. sp. 1 third-stage larva in C. gariepinus (Clariidae) and Physalopteridae gen. sp. 2 third-stage larva in Serranochromis angusticeps (Boulenger) (Cichlidae), all representing new host and geographical records. Spinitectus zambezensis Boomker, 1993 is considered a junior synonym of S. polli.

Two species of parasitic nematodes, Heliconema ahiri Karve, 1941 (Physalopteridae) and Procamallanus (Spirocamallanus) anguillae Moravec et al., 2006 (Camallanidae), were recorded from the Indonesian shortfin eel Anguilla bicolor bicolor Mc-Clelland in the Chalakkudi River and Veli Lake, respectively, both Kerala, India. The former species (H. ahiri), rediscovered from eels in India after 82 years from its original description, has been redescribed and revalidated based on its specific feature (presence of groups of minute denticles in the mouth) distinguishing it from other congeners; its finding in A. b. bicolor represents a new host record. The latter species (P. anguillae) has been recorded in India for the first time. SEM examination of its first-stage larvae from uterus has shown that P. anguillae is another species of Procamallanus whose larvae possess a crown of digit-like processes at the tail tip.

The little-known nematode species Heliconema africanum (Linstow, 1899) n. comb. (Physalopteridae) is redescribed based on light and scanning electron microscopical examinations of specimens collected from the stomach of the African longfin eel Anguilla mossambica (Peters) in the Nahoon River, Eastern Cape Province, South Africa. This species, previously misidentified as Heliconema longissimum (Ortlepp, 1922), is a common parasite of eels in South Africa. The systematic status of H. longissimum, a species originally described from unidentified Australian snakes, is unclear and probably several morphologically closely related species have been included under this name.

Two new nematode species are described from the paddlefish Polyodon spathula (Walbaum) (Polyodontidae, Acipenseriformes) from the Mississippi River drainage, United States, based on specimens previously deposited in the U.S. National Parasite Collection. Those specimens were Camallanus polyodontis n. sp. (Camallanidae) from the host (site of infection not given) collected in the Yellowstone River, Montana in 1974 and Syngnathinema chitwoodi n. sp. (Daniconematidae) from the body cavity of fish collected in Mississippi in 1926. Camallanus polyodontis (male and female) is mainly characterized by the presence of a conspicuously large, oval, sclerotized formation at the base of tridents on the buccal capsule, by which it distinctly differs from all congeners. It also differs from other North American species of the genus by additional features such as the body size, the length of spicules, or the length of the female tail. Syngnathinema chitwoodi (a single subgravid female) differs from the only other congener, Syngnathinema californiense Moravec, Spangenberg and Frasca, 2001, a parasite of the circulatory system of the pipefish in California and British Columbia, mainly in that the posterior end of the muscular esophagus is not submerged into the anterior end of the glandular esophagus. Previous reports of Camallanus oxycephalus Ward and Magath, 1917 in P. spathula may be misidentifications of C. polyodontis.

Gravid females of two species of philometrid nematodes (Philometridae) were collected from marine perciform fishes in Japanese waters, mainly from the southern Sea of Japan. Based on light microscopy and scanning electron microscopy examinations, the previously described but poorly known species Philometra cryptocentri Yamaguti, 1961 is redescribed from specimens recovered from the abdominal cavity of Acanthogobius flavimanus (Temminck et Schlegel), Pterogobius elapoides (Günther) and P. zonoleucus Jordan et Snyder (all Gobiidae) (all new host records); the number (14) and arrangement of cephalic papillae in this species are described for the first time. The new species, Philometroides branchiostegi sp. n. from head tissues of Branchiostegus japonicus (Houttuyn) (Malacanthidae), based on a single specimen, is mainly characterized by the embossment of the entire body except for the cephalic end, presence of four submedian pairs of large cephalic papillae of external circle and two small lateral single papillae of internal circle, pair of large papilla-like caudal projections, the oesophagus with a distinct anterior inflation, by a markedly small body (length about 18 mm) and the larvae 306–465 μm long.

First-stage larvae of camallanid nematodes Procamallanus (Procamallanus) laeviconchus (Wedl, 1862) and Procamallanus (Procamallanus) sp. from naturally infected Distichodus niloticus (Hasselquist) and Clarias gariepinus (Burchell), respectively, from Lake Turkana, Kenya (new geographical records) are described, being for the first time studied by scanning electron microscopy. Larvae of both species are characterised by the presence of a dorsal cephalic tooth, four submedian cephalic papillae and a pair of amphids, and by the elongate tail with several terminal digit-like processes. The latter formations probably serve for the attachment of larvae to the substrate in water when the larvae attract copepod intermediate hosts by their movements; these structures, especially their numbers, may be of taxonomic importance in camallanid nematodes. The nematode genus Procamallanus Baylis, 1923 contains many species parasitizing freshwater, brackish-water and marine fishes and, less often, amphibians. The following five subgenera of Procamallanus were recognised by Moravec and Thatcher (1997) (see also Gibbons 2010): Procamallanus Baylis, 1923, Spirocamallanus Olsen, 1952, Spirocamallanoides Moravec et Sey, 1988, Punctocamallanus Moravec et Scholz, 1991 and Denticamallanus Moravec et Thatcher, 1997. Of them, only representatives of Procamallanus and Spirocamallanus are known from the African continent (totally 7 species), whereby P. (P.) laeviconchus (Wedl, 1862) (the type species of the genus) has so far been the only species of the former subgenus reported from freshwater fishes in Africa. This is also the only African Procamallanus species in which the life cycle has hitherto been studied and the first-stage larvae described (Moravec 1975). While redescribing P. laeviconchus from Synodontis spp. (congeneric with its type host) in Botswana (including SEM study), Moravec and Van As (2004) drew attention to the fact that this species was reported from about 30 fish species belonging to seven families and the specimens often exhibited morphological differences; they considered the presence of an unusually lobed circumoral flange a characteristic feature of P. laeviconchus, already illustrated by Wedl (1862) in the original description.
