[Q]: The existence of coronaviruses in bats is unknown until the recent discovery of bat-SARS-CoV in Chinese horseshoe bats and a novel group 1 coronavirus in other bat species. Among 309 bats of 13 species captured from 20 different locations in rural areas of Hong Kong over a 16-month period, coronaviruses were amplified from anal swabs of 37 (12%) bats by RT-PCR. Phylogenetic analysis of RNA-dependent-RNA-polymerase (pol) and helicase genes revealed six novel coronaviruses from six different bat species, in addition to the two previously described coronaviruses. Among the six novel coronaviruses, four were group 1 coronaviruses (bat-CoV HKU2 from Chinese horseshoe bat, bat-CoV HKU6 from rickett's big-footed bat, bat-CoV HKU7 from greater bent-winged bat and bat-CoV HKU8 from lesser bent-winged bat) and two were group 2 coronaviruses (bat-CoV HKU4 from lesser bamboo bats and bat-CoV HKU5 from Japanese pipistrelles). An astonishing diversity of coronaviruses was observed in bats.

[Q]: We previously identified unusual variants of Moloney and Friend ecotropic mouse gammaretroviruses that have altered host range and are cytopathic in cells of the wild mouse species Mus dunni. Cytopathicity was attributed to different amino acid substitutions at the same critical env residue involved in receptor interaction: S82F in the Moloney variant Spl574, and S84A in the Friend mouse leukemia virus F-S MLV. Because M. dunni cells carry a variant CAT-1 cell surface virus receptor (dCAT-1), we examined the role of this receptor variant in cytopathicity and host range. We expressed dCAT-1 or mCAT-1 of NIH 3T3 origin in cells that are not normally infectible with ecotropic MLVs and evaluated the transfectants for susceptibility to virus infection and to virus-induced syncytium formation. The dCAT-1 transfectants, but not the mCAT-1 transfectants, were susceptible to virus-induced cytopathicity, and this cytopathic response was accompanied by the accumulation of unintegrated viral DNA. The dCAT-1 transfectants, however, did not also reproduce the relative resistance of M. dunni cells to Moloney MLV, and the mCAT-1 transfectants did not show the relative resistance of NIH 3T3 cells to Spl574. Western analysis, use of glycosylation inhibitors and mutagenesis to remove receptor glycosylation sites identified a possible role for cell-specific glycosylation in the modulation of virus entry. Virus entry and virus-induced syncytium formation using the CAT-1 receptor are mediated by a small number of critical amino acid residues in receptor and virus Env. Virus entry is modulated by glycosylation of cellular proteins, and this effect is cell and virus-specific.

[Q]: INcnak! G. A. and AL-YAMAN F. 1988. A comparative assessment of four serological methods used in the detection and measurement of anti-parasite antibodies in the serum of the amphibian, Bufo viridis. International Journal for Parasitology 18: 371-377. Antibodies against Cn'thidia fasciculata choanomastigotes were detected in green toad (Bufo viridis) sera by direct agglutination, indirect haemagglutination (IHA), complement-fixation test (CFT) and enzyme-linked immunosorbent assay (ELISA). Correlation coefficients (r) were calculated for comparisons between each of the techniques and regression formulae derived in order to convert antibody levels as determined by one immunological method to that of another. The highest mean titre obtained by ELISA was approximately 1.5-3.5 times greater than those obtained by the other techniques whilst CFT gave the lowest values. IHA and ELISA titres were affected by different preparations of the crithidial antigen extracts. Highly significant r values were determined for control sera when IHA was compared to ELISA (r> 0.79), and to both CFT and ELISA with immune animals (r> 0.96). ELISA would seem most applicable for screening other lower vertebrates for anti-parasite antibodies especially in areas of human disease prevalence.
