Abstract:
This
study reports an outbreak of megabacteriosis in canaries (Serinus
canaria) in the central area of the State of Rio Grande do Sul,
Brazil. In a flock of 200 canaries, 25 birds died with previous
clinical signs of chronic diarrhea, respiratory distress, incoordination,
ruffled feathers, and progressive weight loss. Nine sick birds were
sent to the laboratory for diagnosis and latter submitted to euthanasia
and necropsy. Grossly, there were proventricular dilatation, pale
to yellow liver, and mild hemorrhages in the intestinal tract. Microscopically,
there were large bacillus-like slightly basophilic structures distributed
in parallel layers in the mucosal surface and inside of the mucosal
folds. Mild inflammatory infiltrate (lymphoplasmacytic and heterophilic)
was also seen in the mucosa of the proventriculus. Proventricular
scrapings and mounts of feces stained with Gram stain revealed large
bacillus-like Gram positive structures. The structures were PAS
positive in histological sections of the proventriculus and were
identified as megabacteria. |

Abstract:
Canine
hip dysplasia (CHD) is an orthopedic condition frequent in dogs
of large and giant breeds. Its progression causes degenerative alterations
which are generally irreversible. The precise diagnosis in young
animals favors the selection to control CHD, and enables the application
of more efficient therapeutic options before the development of
degenerative articular disease. The distraction index is the most
efficient and sensitive radiographic technique for the diagnosis
of CHD when compared to traditional methods such as Norberg Angle
and the method of the Orthopedic Foundation for Animals (OFA). The
index yields trustworthy results from 16 weeks of age on, enabling
the selection of healthy animals for breeding purposes, as well
as the early treatment of affected animals with conservative options
or juvenile pubic symphysiodesis. |

Abstract:
We have analyzed
radiographs of a 2 month-old male setter with congenital pleuroperitoneal
diaphragmatic hernia, which was referred to the Radiographic Service
of the Veterinary Hospital of the Veterinary Medicine School of
the Universidade de São Paulo. Survey radiographs showed
extreme cranial displacement of the right diaphragmatic line and
displacement of the cardiac silhouette cranial and to the left.
The survey radiographs did not provide enough information to make
the diagnosis. The barium upper gastrointestinal tract study enabled
the visualization of the topographic alteration of the pyloric portion
of the stomach and liver, both of them displaced into the right
hemithorax, but contained by the diaphragmatic line. Besides being
a rare condition, this hernia had extremely large dimensions, differing
somewhat from the scarce literature data on the subject. |

Abstract:
The ocular adnexa consist of the eyelids, conjunctiva, lacrimal
system, orbital fascia and ocular muscles. These structures are
prone to congenital abnormalities and can acquire inflammatory,
infectious, traumatic and neoplastic disorders. Clinical examination
and complementary diagnostic procedures are of great importance
to determine whether the tumors are of primary or secondary origin.
Orbital tumors are generally primary and malignant; palpebral tumors
occur very often and are in most of the cases benign in dogs and
malign in cats, in which the occurrence of carcinomas prevails.
Neoplasias of the third eyelid are generally secondary to conjuctival
disorders. Neoplasias affecting the lacrimal system are rare. This
review emphasizes the most important neoplasias of the ocular adnexa
and discusses the prevalence of small animal ocular tumors, as well
as the importance of the veterinary ophthalmic oncology.

Abstract:
This
review is presented in the light of the scarce information regarding
feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV)
in wild felids in Brazil. In this part, the agents will be presented,
as well as history, epizootiology, modes of transmission, pathogenesis
and clinical aspects in their hosts. FeLV infection is rare in most
nondomestic felid species, but lentiviruses closely related to FIV
have been reported in a wide range of felids worldwide. While FeLV
is pathogenic in
wild felids, the pathogenicity of the different lentiviruses is
controversial in these species. In the second part, diagnostic
procedures will be presented, and the need to adopt surveillance
programs and preventive measures to control infection in free-ranging
and captive populations will be discussed. |

Abstract:
Sporotrichosis
is a chronic disease caused by the dimorphic fungus Sporothrix schenckii.
In Brazil, the incidence of sporotrichosis acquired through contact
with infected cats is increasing, and in Rio de Janeiro the notification
of its occurrence is now mandatory. The aim of this article is to
point out the zoonotic potential of the cat in relation to sporotrichosis
and to propose integrated actions between the Municipal Center of
Health and the Center of Control of Zoonoses to control the disease.
The diagnosis of four human cases of sporotrichosis associated to
transmission through domestic cats in a public hospital in Rio de
Janeiro led to the present report and literature review. |
