Thanks for the link, it works!
I’ve added this code into the funtions.php and my category appear in the “body”:

// add category nicenames in body and post class
function category_id_class($classes) {
	global $post;
	foreach((get_the_category($post->ID)) as $category)
		$classes[] = $category->category_nicename;
	return $classes;
}
add_filter('post_class', 'category_id_class');
add_filter('body_class', 'category_id_class');

Thanks for your help.
