Dissemination kinetics and pathology of canine isolate in a guinea pig infection model.

Despite significant progress made in elucidating the mechanism of acute human leptospirosis in different organs, there is a paucity of information in organs such as the heart, pancreas, brain, and adrenal gland. This study was designed to establish leptospire dissemination kinetics and patho-morphological changes associated with these orangs in the guinea pig infection model using cultural isolation (CI), polymerase chain reaction (PCR), Warthin Starry silver stain (WSss), immunohistochemistry (IH), and transmission electron microscopy (TEM). Twenty guinea pigs were inoculated intra-peritoneally with a low dosage of 1 × 10 serovar Icterohaemorrhagiae and 10 as control using distilled water.

Cultural, histochemical, and immunohistochemical detection of pathogenic species in the kidneys of cattle slaughtered in two abattoirs in Southwest Nigeria.

The impact of leptospirosis on food animals and humans has not been fully elucidated. This study was designed to determine the prevalence of pathogenic organism in renal tissues of slaughtered cattle from two major abattoirs in southwestern Nigeria. One hundred and seventy (170) kidney samples of different breeds, ages, and sexes were collected and examined using cultural isolation, microscopic agglutination test (MAT), Warthin silver (WSs) impregnation and immunohistochemistry (IH).

Hepatitis E Virus infection seroprevalence and the associated risk factors in animals raised in Ibadan, Nigeria.

Hepatitis E (HE) is an important viral hepatitis of global public and livestock health, and food security significance due to the ubiquitous distribution, multiple transmission route and zoonotic potentials. HE is also endemic in most developing countries including Nigeria. This study therefore investigates the seroprevalence and associated risk factors of HEV infection in pigs raised in Ibadan, Nigeria.

Prevalence and renal pathology of pathogenic spp. in wildlife in Abeokuta, Ogun State, Nigeria.

There is paucity of information on the prevalence of leptospirosis in wildlife in Nigeria. This study investigated the prevalence and renal pathology of leptospirosis in wild animals in Southwest Nigeria. One hundred and five kidney samples were examined from 10 different wildlife species (antelope) greater cane rat (GCR), hare, African giant rat (AGR), tree hyrax, civet cat, monitor lizard, python, bushbuck and partridge) using a combination of Ellinghausen McCullough Johnson Harris (EMJH) medium, microscopic agglutination test (MAT), Warthin- Starry silver stain (WSss) and immunohistochemistry.

Rhabdomyosarcoma in a terrestrial tortoise (Geochelone nigra) in Nigeria: a case report.

A skeletal muscle tumour (rhabdomysarcoma) was diagnosed in a 4-year-old captive female terrestrial tortoise (Geochelone nigra) weighing 7 kg presented at the Veterinary Teaching Hospital, University of Ibadan, Ibadan, Nigeria. The tumour was located at the anterior right portion of the body and ventral to the carapace. The location of the tumour prevented the tortoise from extending its head from the body.
