Translator und "and"

Hallo zusammen,

wenn ich im Feld "Translator" mehrere Namen angebe und diese wie 
gewohnt mit "and" verbinde, dann erhalte ich am Ende in der 
Biblliographie ebenfalls ein "and" und keine übersetzte Variante.

Minimalbeispiel:
\documentclass{article}
\usepackage{ucs}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{jurabib}
\begin{document}
\citet{Lem.S:1980}
\bibliographystyle{jurabib}
\bibliography{germanistik}
\end{document}


@book{Lem.S:1980,
	Address = {Frankfurt a. M.},
	Author = {Stanis{\l}aw Lem},
	Date-Modified = {2004-11-01 10:50:43 +0100},
	Flanguage = {Polish},
	Gelesen = {gelesen},
	Keywords = {Phantastik, Science Fiction, Literatur, Liz, Diss, Lem},
	Note = {(Original: Fantastyka i futurologia)},
	Standort = {Privat},
	Title = {Phantastik und Futurologie},
	Translator = {Beate Sorger and Wiktor Szaki},
	Volume = {2},
	Year = {1980}}

Das Ergebnis sieht folgendermassen aus:  Lem, Stanis
