| ABSTRACT Chromobacterium violaceum is a rare opportunistic pathogen that causes highly fatal infections in domestic animals and humans. This report describes a fatal case suggestive of septicemia in a four-day-old female calf with chromobacteriosis. The calf had suppurative omphalophlebitis, suppurative fibrinous polyarthritis, anterior uveitis with bilateral fibrin deposition, fibrinous peritonitis, lymph node abscess and multifocal lymphocytic and neutrophilic encephalitis with multifocal hemorrhages. C. violaceum was isolated from the spleen and peri-renal lymph node and its identity was confirmed by PCR and sequencing. The pathogen was sensitive to azithromycin, gentamicin, enrofloxacin, norfloxacin, marbofloxacin, ciprofloxacin, erythromycin,... |

| ABSTRACT Mutant color alopecia is an ectodermical defection of color dilution, characterized by partial alopecia, dry, shine-less hair, and peeling and papule. Melanization damages also occur on the cortical structure of the affected hair. The animals affected have big melanin grains with irregular shape on the basal keratinocytes, also on the hair matrix cells and rod. Therefore, there is not a specific treatment that makes any difference on the syndrome evolution. Although in some animals, it is possible to use weekly showers with benzyl peroxide to reduce seborrhea formation and secondary infections. There is evidence that the condition in dogs is caused by a single nucleotide polymorphism in the gene encoding the melanophilin protein. In the present... |

| ABSTRACT Ehrlichia infections in cattle are frequent in Africa but have also been reported in Brazil and North America. This paper reports natural infection by Ehrlichia sp. associated with Babesia bigemina and Anaplasma marginale in a calf in the municipality of Campo Grande, state of Mato Grosso do Sul, Brazil, presenting polioencephalomalacia. The molecular evidence, based on a fragment of the dsb gene, indicates a species of Ehrlichia genetically related to Ehrlichia canis and other species of the genus found in the tick Rhipicephalus (Boophilus) microplus and a calf from Brazil (99 to 100% identity). It was not possible to associate the clinical signs with Ehrlichia infection due to co-infections and histological evidence of another disease. However,... |
