“…According to Silveira and Nishioka 12 ,in Bothrops sp cases, edema is an early sign of envenoming. Many studies report that pain and edema are, respectively, the dominant symptom and sign in Bothrops sensu lato cases, present in more than 90% of patients 22,25,26 .…”

Introduction: This study analyses the cases of all bites (including dry bites) caused by Bothropoides jararaca attended at the Vital Brazil Hospital of the Butantan Institute, State of São Paulo, Brazil. Methods: A retrospective study was conducted of patients bitten by Bothropoides jararaca (n=792) from January 1990 to December 2004. The characteristics of the snake specimen, data related to the accident and clinical manifestations on admission were obtained from patient medical records. Results: The majority of the cases in this study were caused by female and juvenile snakes. No stomach contents were found in 93.4% of the snake specimens after dissection. No statistical difference was observed between the occurrence of dry bites and the maturity or sex of the snake. The median SVL of snakes in mild and moderate cases was 40.5cm and in severe cases, SVL increased to 99cm. Necrosis was more common in the digits of the feet and hands (4.8%) compared to the other body regions (1.8%). A significant difference was verified between severity and a time interval greater than six hours from the bite to hospital admission. A significant association was verified between gingival bleeding and abnormal blood coagulability. In accidents caused by adult snakes, necrosis was more frequent (7.2%) compared to accidents caused by juvenile snakes (1%). Conclusions: In this work, the association between certain epidemiological data and the evolution of biological parameters in the clinical course of Bothrops sensu latu accidents were highlighted, contributing to the improvement of snake bite assistance.

“…However, no apparent investigators have thus far explored the bacterial and fungal microbiota of this species. These findings may reveal the influence of microbiota on the health of the snakes, birth and mortality rates, and role as a secondary etiological agent in infections resulting from snakebites (Costello et al 2010;Ferreira Junior et al 2009;Fonseca et al 2009;Paula Neto et al 2005). The aim of this study was to characterize microbiota in B. insularis snakes using molecular identification of aerobic bacteria and fungi isolated from mouth, eyes, and cloaca using a culture-dependent approach.…”

Bothrops insularis, known as the golden lancehead snake, has its natural habitat restricted to Queimada Grande Island on the southern coast of Brazil. This culture-dependent study aimed to identify microorganisms obtained from the mouth, eyes, and cloaca of this species. Swabs from 20 snakes were collected for fungal and bacterial isolation. DNA was extracted from all samples, and identification was performed by amplifying the ITS1-5.8S-ITS2 regions and the 16S rDNA gene, respectively. All strains were identified and deposited in the GenBank nucleotide database. MEGA v6.0 software was utilized to construct phylogenetic trees. In total, 100 strains were isolated and characterized, from which 42 fungi were distributed into 23 species and 58 bacteria into 13 species. The genus Fusarium was predominant since 11 strains and probably a new species was isolated from this fungus. Pseudomonas aeruginosa and Enterococcus faecalis were the predominant groups of aerobic bacteria isolated. Phylogenetic analyses between bacterial and fungal sequences suggest a similarity between the microorganisms found on the island and on the continent. These findings may be attributed to anthropic actions resulting from both expeditions to the island and actions of migratory birds, which are the main sources of food for snakes.

Accidents involving poisonous animals in southern Santa Catarina State, Brazil, from 1994 to 2005 were evaluated with the aim of verifying their frequency through the analysis of 2,625 victim's reports involving poisonous animals from the SINAN (System of Injury Notification Information) files of the Municipal Health Secretary of the AMESC and AMREC microregions, formed by 27 municipalities. Statistical analysis was performed using the chisquare exact test to verify similarities between the AMREC and AMESC microregions, where p values ≤0.05 were considered significant. The results demonstrated that: 52.95% (n = 1,390) of occurrences involved spiders, 18.13% (n=476) snakes, 5.00% (n=131) bees, 2.29% (n= 60) caterpillars, 1.41% (n=37) scorpions, 5.45% (n=143) other animals and 14.78% (n=388) unknown. The anatomic region that suffered the most bites was the feet 16.11% (n=444). Accidents were more frequent in men 54.64% (n=1.437) than in women 45.25% (n=1,188). In only 1.18% (n=31) of cases did recovery present sequelae. The months presenting the highest number of recorded cases were October through March, spring and summer in Brazil.The high frequency of victim recuperation suggests that the public health system is efficient, and the low frequency of recovered victims with sequelae also suggests that this system is fast and well-adjusted. However, there may have been deficiencies in the epidemiologic information system.
