title: Evidence for direct transmission of the cat lungworm Troglostrongylus brevior (Strongylida: Crenosomatidae).
abstract: Metastrongyloids of cats are emerging pathogens that may cause fatal broncho-pulmonary disease. Infestation of definitive hosts occurs after ingestion of intermediate or paratenic hosts. Among metastrongyloids of cats, Troglostrongylus brevior and Troglostrongylus subcrenatus (Strongylida: Crenosomatidae) have recently been described as agents of severe broncho-pulmonary disease. Here, we provide, for the first time, observational evidence suggesting the direct transmission of T. brevior from queen cat to suckling kittens. This new knowledge will have a significant impact on current scientific information of this parasite and shed new light into the biology and epidemiology of metastrongyloid nematodes.
