Streptococcus bovis infection was diagnosed in pigeons from 20 lofts submitted for post mortem investigation. Clinical signs were very variable and ranged from hyperacute death to chronic lameness with arthritis. Lesions were generally unspecific except for single cases of muscle necrosis with purulent myositis. Histological examinations demonstrated the septicaemic nature of the infections. Intravenous inoculations of S. bovis resulted in prostration, long lasting loss of weight and polyuria. Microscopically purulent hepatitis and nephritis were the most characteristic lesions. After oral inoculation no clinical signs were seen.

Rabdomiolysis and acute renal failure secondary to influenza infection are rare. Up to now, few cases have been reported and most of them are primarily among children. Myositis associated to influenza infection is caused by the toxic effect of the virus in the muscular fiber, dysregulation of inflammatory cytokines and a cross reaction between the muscle fiber and the viral particles. We present the case of a 57 year old male with a diagnosis of H1N1 influenza who developed polyuria, oligoanuria, elevation of lactic dehydrogenase, myoglobin, creatinin phosphokinase and an electromyography with a myopathic pattern. The diagnosis of rabdomyolisis and acute renal failure were made, hemodyalisis was started and the patient improved satisfactorily. This is the first report of a patient with radmoyolisis and acute renal failure secondary to A H1N1 influenza treated during the Mexico epidemic.

A novel Sarcocystis species has recently been reported in the domestic pigeon (Columba livia f. domestica) as intermediate host, causing severe central nervous signs similar to Paramyxovirus-1 or Salmonella Typhimurium var. cop. infection. Transmission of the parasite via the northern goshawk (Accipiter gentilis) as definitive host has been established. Experimental infection of domestic pigeons with sporocysts excreted by experimentally infected northern goshawks reproduced the natural infection in the pigeon, proving the causative role of the parasite in the disease. Here, we describe in greater detail the course of the fulminant biphasic disease depending on the infectious dose. Pigeons infected with 10(3) or 10(4) sporocysts showed clinical signs of polyuria and apathy around 10-11 days postinfection (dpi) and sudden neurological signs 51-57 dpi as a second phase of disease. Pigeons infected with higher doses died within 7-12 dpi, also showing polyuria and apathy but without nervous signs. At necropsy, livers and spleens had multifocal necroses and infestations with parasitic stages, namely, schizonts. Moreover, lesions and schizonts were also found in the lung, bone marrow, and next to blood vessels in the connective tissue of various organs. Pigeons infected with 102 sporocysts remained symptomless until 58-65 dpi, when sudden central nervous signs occurred. Major histopathologic findings of pigeons with neurological signs were encephalitis and myositis of virtually every skeletal muscle with high infestations of sarcocysts. Only mild myocarditis and very few cysts were found in the heart muscles. Importantly, a sentinel pigeon developed identical lesions when compared to those of low-dose infected pigeons, suggesting a risk of mechanical transmission of sporocysts from freshly infected to uninfected pigeons in a flock. By contrast, chickens failed to develop any clinical signs or pathologic lesions in the same experiment. The findings further characterize the new highly pathogenic disease in domestic pigeons, which clinically mimics paramyxovirosis and salmonellosis in both phases of the disease and exclude chickens as further intermediate host species.
