[Helminth fauna Anseriformes (Aves) in the Lodz Zoological Garden].

In the years 1959-1990 429 birds on 30 species of Anseriformes were examined post mortem at Zoo Lódź. The helminths were found in 108 birds (25.17%) of 19 species. In infected birds there were found 4 species of trematodes: one of them, Catatropis verrucosa is in Poland new for Cygnus olor; 9 species of cestodes--7 of them are in Poland new for examined hosts; namely: Drepanidotaenia lanceolata for Dendrocygna viduata, Cygnus atratus, Branta bernicla, and Anas platyrhynchos; Microsomacanthus paracompressus for Cygnus olor; Dicranotaenia coronula for Chloephaga picta and Cairina moschata; Cloacotaenia megalops for Branta bernicla, Tschertkovilepis setigera for Cygnus olor, Anser indicus, Branta bernicla and Anas platyrhynchos; Fimbriaria fasciolaris for Cygnus olor and Chloephaga picta; Sobolevicanthus gracilis for Cygnus atratus, Chloephaga picta and Tadorna tadorna; 13 species of nematodes--7 of them are in Poland new for examined hosts, namely: Cyathostoma variegatum for Cygnus atratus, Anser indicus and Anser caerulescens; Syngamus trachea for Anser indicus; Echinuria uncinata for Anser indicus; Ganguleterakis dispar for Cgynus melanocoryphus, Cgynus olor and Anser caerulescens; Pterothominx caudinflata for Anser indicus; Amidostomum ansersis for Cygnus olor and Branta bernicla; Capillaria anatis for Anas acuta. No acanthocephalans were observed.

Identification and characterization of avihepadnaviruses isolated from exotic anseriformes maintained in captivity.

Five new hepadnaviruses were cloned from exotic ducks and geese, including the Chiloe wigeon, mandarin duck, puna teal, Orinoco sheldgoose, and ashy-headed sheldgoose. Sequence comparisons revealed that all but the mandarin duck viruses were closely related to existing isolates of duck hepatitis B virus (DHBV), while mandarin duck virus clones were closely related to Ross goose hepatitis B virus. Nonetheless, the S protein, core protein, and functional domains of the Pol protein were highly conserved in all of the new isolates. The Chiloe wigeon and puna teal hepatitis B viruses, the two new isolates most closely related to DHBV, also lacked an AUG start codon at the beginning of their X open reading frame (ORF). But as previously reported for the heron, Ross goose, and stork hepatitis B viruses, an AUG codon was found near the beginning of the X ORF of the mandarin duck, Orinoco, and ashy-headed sheldgoose viruses. In all of the new isolates, the X ORF ended with a stop codon at the same position. All of the cloned viruses replicated when transfected into the LMH line of chicken hepatoma cells. Significant differences between the new isolates and between these and previously reported isolates were detected in the pre-S domain of the viral envelope protein, which is believed to determine viral host range. Despite this, all of the new isolates were infectious for primary cultures of Pekin duck hepatocytes, and infectivity in young Pekin ducks was demonstrated for all but the ashy-headed sheldgoose isolate.

Molecular basis of bird respiration: primary hemoglobin structure component from Tufted duck (Aythya fuligula, Anseriformes)--role of alpha99Arg in formation of a complex salt bridge network.

The primary structure of the major hemoglobin component, HbA (alpha(A)- and beta-chain), from Tufted duck (Aythya fuligula) is presented. The separation of the globin subunits was achieved by ion exchange chromatography on CM-cellulose in 8 M urea. The amino acid sequence was determined by automatic Edman degradation of native chains as well as tryptic and hydrolytic peptides in a gas-phase sequencer. The automated homology model was generated by the protein structure modeling package WHAT IF using the crystal structure coordinates of Bar-headed goose hemoglobin. The 3D structure prediction enables alpha99Arg and beta101Glu to emerge as a new intersubunit contact site not found in the hemoglobin structure of any other species. alpha99Arg forms a complex salt bridge network involving alpha99Arg-beta101Glu-beta104Arg-beta108Asp. Also the substitution at alpha34 --> Ile, alpha38 --> Gln and beta55 --> Leu serves to stabilize the oxy-structure, leading to higher oxygen affinity.

Fungal diseases of columbiformes and anseriformes.

Because of the high incidence of aspergillosis, fungal disease is an important condition in the waterfowl. Although this is generally a disease of individual birds, epizootics have been reported when overwhelming spore loads are present. By contrast, the occurrence of fungal disease is quite sporadic in the pigeon. In both groups of birds, however, the zoonotic potential of fungal diseases such as cryptococcosis, histoplasmosis, and blastomycosis is clinically significant. The abundant creatinine levels in droppings serve as a nitrogen source for these organisms. This allows their numbers to increase dramatically, which in turn increases the risk of disease transmission. Because pigeons often live in close proximity to people, their role in disease transmission is considered particularly important.

Activities of mixed function oxidases, UDP-glucuronyl transferase and sulphate conjugation enzymes in galliformes and anseriformes.

The activities of certain drug metabolizing enzymes have been measured in liver and kidney slice preparations from domesticated birds. Aminopyrine demethylase activity was significantly lower in liver slices from the duck (Aylesbury X Pekin, Khaki-Campbell) than from the rat (Wistar), and in the Aylesbury X Pekin duck lower than in the turkey (Triple 6 FLX), chicken (Brown Leghorn, Rhode Island Red X Light Sussex) and goose (Emden X Doulouse). The microsomal cytochrome P-450 was lower in duck liver (Aylesbury X Pekin) than in rat liver, and the aniline hydroxylase and aminopyrine demethylase activities in a 10,000 g supernatant fraction of liver were lower in duck preparations (Aylesbury X Pekin, Khaki-Campbell) than rat preparations. These observations suggest that the duck is likely to be susceptible to drugs which are metabolized by the cytochrome P-450 containing mono-oxygenases. UDP-Glucuronyl transferase activity was not detectable in liver and kidney slices from two mature geese. This observation was not the outcome of a deficiency of UDP-glucuronic acid, rapid breakdown of glucuronide by beta-glucuronidase or the presence of a substance inhibitory to UDP-glucuronyl transferase. Liver slices from geese, ducks (Aylesbury X Pekin) and chickens contained low UDP-glucuronyl transferase and high sulphate conjugation enzyme activities, whereas the reverse was found in Khaki-Campbell ducks. The activities of UDP-glucuronyl transferase and the sulphate conjugation enzymes were both relatively high in liver slices from the turkey and rat. The kidney contained lower enzyme activities than the liver except in the duck (Aylesbury X Pekin), in which low activities of aminopyrine demethylase and UDP-glucuronyl transferase were present in slices of both organs. In liver slices from chickens and geese the activities of aminopyrine demethylase and the sulphate conjugation enzymes were similar in mature and immature birds, and the activity of UDP-glucuronyl transferase was considerably higher in chicks and goslings than in mature birds of the same species. In the chick the activities of aminopyrine demethylase, UDP-glucuronyl transferase and the sulphate conjugation enzymes were higher in the duodenum than the remainder of the alimentary tract. The activities of these enzymes in pieces of duodenum were as high as those in slices of liver. The inclusion of sulphate in the incubation medium produced a significant increase in the synthesis of p-nitrophenyl sulphate in liver slices and not kidney slices except those from the duck. The kidney slices seemed to produce sufficient sulphate for the reaction of the sulphate conjugation enzymes to proceed at the maximum rate, but the liver slices did not do so.

Parhadjelia cairinae n. sp. (Nematoda: Habronematoidea: Habronematidae) in the Muscovy duck, Cairina moschata (Linnaeus, 1758) (Aves: Anseriformes: Anatidae), from the area de conservacion Guanacaste, Costa Rica.

A new species of Parahadjelia occurs in the muscovy duck, Cairina moschata (Linnaeus, 1758), from the Area de Conservacion Guanacaste, Costa Rica. The new species differs from Parhadjelia neglecta Lent and Freitas, 1939, in the body size, in the spicules shape and ratio of spicules, and in having 2 pairs of sessile papillae near the tail tip of the male. The characters exhibited by P. neglecta and the new species validate its generic status distinct from Hadjelia.
