Equine coital exanthema caused by equid alphaherpesvirus 3: a report of an outbreak in northeastern Brazil

ABSTRACT: Equine coital exanthema is a venereal infectious disease poorly reported in horses in Brazil and was never described in the northeastern region of the country. This work aims to describe the clinical and pathological aspects of an outbreak of equine coital exanthema caused by equid alphaherpesvirus 3, occurred in a herd of horses at the semiarid region of the State of Rio Grande do Norte. Main clinical signs consisted of anorexia, hiporexia, fibrinous or purulent secretion in the penis mucosa and vagina. Two mares presented mild to minimal lesions that consisted of scars in the mucosa of the vagina and in the perivulvar region. In a stallion the disease consisted of severe, multifocal, umbilicated-exanthematous ulcers of approximately 1cm in diameter on the penis mucosa. Other areas where ulcers and crusts were focally observed included the skin of the scrotum and on the lips and mucocutaneous junctions of the oral cavity. Histologically, the main lesion consisted of multifocal severe ulcerative and fibrinous necrotizing balanoposthitis and mild multifocal necrotizing, lymphocytic dermatitis in the lips and scrotum. The equide alphaherpesvirus 3 DNA was amplified in blood samples and penis mucosa using the PCR technique. This is the first report of molecular diagnosis of equine coital exanthema affecting horses in northeastern Brazil. Further studies should be carried out in order to investigate the epidemiology and the importance of this herpetic disease in the country.

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

ABSTRACT Objective: To analyze the spatial distribution of congenital syphilis cases in a state in northeastern Brazil. Method: This is an ecological study, with secondary data for the period from 2008 to 2018, taking as a sample the notified cases of congenital syphilis in Rio Grande do Norte. In the data analysis, the eight health regions of the state were used as units of analysis, and the local and global Moran’s I was performed, with subsequent smoothing through the local empirical Bayesian method, which resulted in thematic maps. Results: The results showed an increase in cases of congenital syphilis in the 3rd and 7thhealth regions. In terms of spatial analysis, this investigation showed clusters in the 3rd, 5th, and 7thhealth regions, with an increased risk for congenital syphilis of up to 2.65 times and with an incidence rate of 7.91 cases per 1,000 live births. Conclusion: The spatial analysis of congenital syphilis cases allowed observing a high incidence in some health regions, with averages above those calculated for the entire state, indicating the need to implement effective strategies to achieve its control.

Genus One

The Bromeliaceae Flora for the state of Rio Grande do Norte, Northeastern Brazil, is presented, based on extensive fieldwork, morphological analyses using herbarium and freshly collected material, and specialized literature. Twenty-six species of bromeliads were recorded in Rio Grande do Norte, distributed in ten genera and in three subfamilies. Bromelioideae was the richest subfamily (eight genera/14 species), followed by Tillandsioideae (one genus/12 species), and Pitcairnioideae (one genus/one species). Aechmea mertensii, Hohenbergia horrida and Tillandsia tenuifolia are new records for Rio Grande do Norte. Eight species (31%) are restricted to the Eastern portion of the state, in the Atlantic Forest. Caatinga dry woodlands harbor 18 species, with remarkable presence of Bromelia laciniosa, Encholirium spectabile, Tillandsia recurvata and T. streptocarpa, the four most widely distributed taxa. We discuss problems related to unclear taxonomic circumscriptions of species or diverging information between authors, more expressively in Hohenbergia, but also in Aechmea, Cryptanthus and Tillandsia. The data presented here might contribute to better understand the morphological variation of these taxa and suggest additional research on their taxonomy. Morphological descriptions, general comments, a map, photo plates and an identification key for all taxa are provided.

Abstract There is great diversity in swine coccidia, which are responsible for causing intestinal disorders ranging from sporadic diarrhea to severe cases of hemorrhagic enteritis. Thus, determining the species of coccidia that affect the animals of a region and associating them with the characteristics of the farms become extremely important. The objective of this study was to determine the prevalence of coccidia parasites in pigs reared in a family farming production system in the Semiarid Region of the State of Paraíba, Northeast Brazil. Fecal samples for analysis were collected from 187 pigs on 51 farms. For morphological analysis, 1,590 sporulated oocysts were used. The prevalence of oocysts in fecal samples was 56.6% (106/187). The most prevalent species were Eimeria suis (21.9%), followed by Eimeria neodebliecki (16.6%), Eimeria perminuta (14.9%), Eimeria polita (12.8%), Eimeria debliecki (10.6%), Eimeria porci (10.1%), Cystoisospora suis (3.7%), Eimeria scabra (1.6%) and Eimeria cerdonis (0.5%). It can be concluded that pigs from the Semiarid Region of the State of Paraíba were parasitized by a diversity of coccidia species, mainly of the genus Eimeria, and predominantly presented with mixed infections occurring in the subclinical form.

Social Technologies

Along the Brazilian history, the federal government has invested in the construction of large-scale water works in the Northeastern region, aiming to fight drought in the Semiárido and to finish with the scarcity of water by means of public policies. However, the climatic context makes drought a natural characteristic of the Northeastern region and cannot be fought against, as it is a natural phenomenon in the area. The objective of the present paper is to investigate how social technologies implemented in the Semiárido have contributed to the strengthening of women’s production capacity in the Hipólito community located in the Mossoró municipality, (State of Rio Grande do Norte, Northeastern Brazil), with the implementation of fertilized cisterns, aiming at gender equality and sustainable agriculture as preconized by Agenda 2030. As a methodological procedure, a qualitative research was carried out, adopting the participatory observation and the focal group techniques. Twelve women who integrate the Mulheres em Ação group participated in the study. It was observed that women positively perceive the impacts of the social technologies of the Um Milhão de Cisternas (P1MC) and Uma Terra e Duas Águas (P1+2) programs in the Hipólito community. Moreover, agriculture practices involved in the construction of the water reuse technology in their yards yielded positive expectations regarding production by the addition of another social technology that will make a larger volume of water available to the community. It is concluded that social technologies coexisting with the Semiárido have contributed to a new territorial development model, consonant with the Semiárido characteristics.
