Characterization of Cetacean Morbillivirus in Humpback Whales, Brazil.

Cetacean morbillivirus is an etiologic agent associated with strandings of live and dead cetacean species occurring sporadically or as epizootics worldwide. We report 2 cases of cetacean morbillivirus in humpback whales (Megaptera novaeangliae) in Brazil and describe the anatomopathological, immunohistochemical, and molecular characterization findings in the specimens.

Pathological, morphological, and molecular characterization of the infection by Brachycladium goliath in humpback whale Megaptera novaeangliae.

The humpback whale (Megaptera novaeangliae) is a cosmopolitan migratory, seasonal mysticete that frequents the Brazilian coast. Strands of specimens may occur during the migratory stay in the country. In 2021 and 2022, three live humpback whales stranded on the coast of Rio Grande do Sul and Santa Catarina states in southern Brazil.

Molecular Survey of Haemosporidian Parasites in Procellariiformes Sampled in Southern Brazil, 2013-22.

The order Procellariiformes includes several species of seabirds that perform long-distance migrations crossing all the oceans. These movements may contribute to the dispersal and exchange of hemoparasites, such as haemosporidians. There is a lack of studies regarding the order Haemosporida in Procellariiformes, and, to date, only the genus Plasmodium has been reported.

Pulmonary acinar adenocarcinoma in a captive lioness (Panthera leo).

Neoplasms in wild felids are more frequently observed in captive animals, of which clinicopathological features of pulmonary tumors are not commonly described. This study aimed to describe the clinical and pathological aspects of a case of diffuse pulmonary acinar adenocarcinoma in a 23-year-old, captive lioness with clinical history of dyspnea, progressive weight loss and inappetence. At necropsy, the lungs were mildly pale, moderately firm, and the pleural surface was diffusely irregular with multifocal to coalescent, grey to white areas.

B-cell small lymphocytic lymphoma in a free-ranging South American fur seal (Arctocephalus australis).

Lymphomas are malignant neoplasms of the hematopoietic system arising from lymphocytes with highly variable biologic behavior. B-cell small lymphocytic lymphoma (B-SLL) is a non-Hodgkin lymphoma infrequently described in domestic and wild animals. The present study describes a case of B-SLL in a free-ranging adult male Arctocephalus australis in Brazil.

A novel variant of Babesia sp. (Piroplasmida) as a hemoparasite in procellariiform seabirds.

Procellariiformes includes pelagic seabirds that only use land for breeding; and also, these sites mostly occur in insular habitats. These peculiar habits make the investigation of hemoparasites a challenging issue. Thus, the data on the blood parasites of Procellariiformes are still scarce.

Diseases associated with feline leukemia virus and feline immunodeficiency virus infection: A retrospective study of 1470 necropsied cats (2010-2020).

Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses affecting cats worldwide, and the prevalence of infection varies considerably according to the geographic area. We retrospectively described FIV- and FeLV-associated diseases in a population of 1470 necropsied cats, of which 396 (26.9%) were infected with FeLV, 199 (13.

Pathological aspects of cutaneous mast cell tumors with metastases in 49 dogs.

Cutaneous mast cell tumor (MCT) is one of the most frequent cutaneous neoplasms of dogs and may vary from well-differentiated to aggressive tumors with metastasis. The authors retrospectively described the gross and histologic aspects of metastatic MCT in 49 dogs. Primary MCT was most commonly identified in the inguinal region (14/35; 40%), and at necropsy multiple, cutaneous nodules were frequently reported (23/49; 47%).

Fatty acids composition and in vivo biochemical effects of Aleurites moluccana seed (Candlenut) in obese wistar rats.

Background: Candlenut (CN) has been used indiscriminately for weight loss. In vivo effects of CN in different doses are scarce.

Objective: To evaluate the effects of CN ingestion in obese rats.

Comparison of immunohistochemical profiles of ovarian germ cells in dysgerminomas of a captive maned wolf and domestic dogs.

We characterized the immunohistochemical expression profiles of dysgerminomas from a 16-y-old maned wolf and 13 domestic dogs using the following biomarkers: Sal-like protein 4 (SALL4), octamer-binding transcription factor 3/4 (OCT3/4), placental alkaline phosphatase (PLAP), c-kit, and vimentin. The maned wolf had nonspecific and long-standing clinical signs of lethargy, anorexia, and weight loss, and was euthanized because of poor prognosis. At autopsy, the left ovary was effaced by a 12 × 8 × 6 cm mass, comprised of anaplastic cells with a mitotic count of 20 mitoses in 10 high power fields.

Native rhizobia from Zn mining soil promote the growth of Leucaena leucocephala on contaminated soil.

Plants on contaminated mining soils often show a reduced growth due to nutrient depletion as well as trace elements (TEs) toxicity. Since those conditions threat plant's survival, plant growth-promoting rhizobacteria (PGPRs), such as rhizobia, might be of crucial importance for plant colonization on TE-contaminated soils. Native rhizobia from mining soils are promising candidates for bioaugmented phytoremediation of those soils as they are adapted to the specific conditions.

[Beyond the transparent body: a consideration of the methods and strategies for examining the homosexual subject].

The aims of the study are to look at methods and strategies used for analyzing people and classifying them as homosexual and to discuss how certain mechanisms which have been established have made it possible to look at their bodies and arrive at conclusions with regard to such persons. We analyze articles from Science Direct, using a Foucaultian approach. We observe the operation of two technologies: medical body imaging techniques and examinations.

Maternal knowledge on child survival in the poorest areas of North and Northeast Brazil.

This study aimed to evaluate knowledge on child survival among mothers of children under five years of age living in nine municipalities in North and Northeast Brazil. A standardized questionnaire was used for home interviews of mothers visited by volunteers from the Pastorate of the Child and mothers not visited by the program (control areas). The association between independent variables and the outcome (visited versus not visited by the Pastorate of the Child) was evaluated using the chi-square test.

[Reproductive characteristics and utilization of preventive health services by childbearing-age women: results of two cross-sectional population-based studies in the far South of Brazil].

Two surveys were conducted (1995 and 2004) on women 15-49 years of age in Rio Grande, Rio Grande do Sul State, southern Brazil, assess patterns in their use of preventive health services. The sample included 1,339 women in 1995 and 1,311 in 2004. A standardized household questionnaire covered their demographic, socioeconomic, reproductive, and health care-utilization characteristics.

Basic indicators of child health in an urban area in southern Brazil: estimating prevalence rates and evaluating differentials.

Objective: To evaluate and compare basic indicators of the health of children under 5 years old in the urban area of Rio Grande, RS, Brazil, for 1995 and 2004.

Methods: Two cross-sectional population studies were carried out in the city. Interviewers were previously trained and applied standardized questionnaires during visits to families with children under 5 years old.
