In many cases, guardians are unaware of the issues of animal health care and do not promote any type of antiparasitic protocol or even perform it inappropriately, which tends to be a zoonotic factor, thus making adequate treatment extremely important. Thus, the fecal stool examination (EPF) together with the evaluation of the blood count, make it possible to diagnose a large number of parasitic diseases. The present study aims to evaluate the results of the hematological and coproparasitological profile in the indicative for verminosis in animals from a kennel in Porto Velho, Rondônia. The work was carried out in a kennel in Porto-Velho, Rondônia, with the collection of blood and feces from dogs of different breeds, age and sex. The hematological examination showed that 12.5% (2/16) of the animals analyzed presented eosinophilia, therefore, 87.5% (14/16) of the group did not exceed the limit of reference values for canines for eosinophils (150 -1,250 eosinophils/µl) used in a veterinary hospital of a higher education institution. The results of the coproparasitological examination indicated that 18.75% (3/16) of the fecal samples had Ancylostoma sp. eggs, therefore, 81.25% (13/16) did not present verminosis. It is concluded that there was a divergence between the methods, in which the coproparasitological examination using the Willis-Mollay technique was evidenced as more reliable in the evaluation of parasitosis, on the other hand, the device for automated hematological examination was not effective, indicating the different results.

Background: The anatomical, physiological, and pharmacological characteristics of reptiles make anesthesia in chelonians particularly challenging. Specific literature regarding safe anesthetic protocols that provide immobilization, antinociception, amnesia, and unconsciousness are scarce. Thus, this paper aims to report the case of a red-footed tortoise submitted to long-duration general anesthesia to celiotomy for foreign body removal. Case: An adult red-footed tortoise (Chelonoides carbonaria), 5.9 kg, was admitted due to hyporexia after ingesting a metallic fishhook. Serial radiographs confirmed the diagnosis and location of the foreign body in the stomach. The animal was premedicated with 0.03 mg/kg dexmedetomidine, 6 mg/kg ketamine, and 0.4 mg/kg butorphanol intramuscularly. After 90 min we inserted a 22G jugular catheter and proceeded to anesthesia induction with 5 mg/kg propofol. We intubated the animal with a 2.5 mm uncuffed endotracheal and started fluid therapy at a rate of 5 mL/kg/h. Surgical anesthesia was maintained with isoflurane in 0.21 oxygen, in a non-rebreathing circuit (baraka), under spontaneous breathing. Expired isoflurane was maintained between 3 and 4.5%. Due to reduced respiratory rate and hypercapnia, we opted for implementing manually-assisted positive pressure ventilation. Morphine (0.5 mg/kg) was administered at 10 and 87 min after the beginning of the surgery for further analgesia when the isoflurane requirement increased significantly. We did not detect any alterations in heart and body temperature. Surgical anesthesia lasted 6 h. During anesthesia recovery, voluntary head retraction and coordinated movement of the limbs occurred at 240 and 540 min after the extubation, respectively. In 2 days, the patient returned to voluntary feeding, being very active and responsive to stimulus. The post-surgical hematologic evaluation was unremarkable. Discussion: Pre-anesthetic medication aimed to promote sedation and preemptive analgesia. Due to its minimal cardiorespiratory depression, we chose the combination of ketamine, dexmedetomidine, and butorphanol. Dexmedetomidine reduced the ketamine dose and caused sufficient muscle relaxation and immobilization to perform the jugular catheter placement. Butorphanol is an agonist-antagonist opioid; that is why we decided to add it to the protocol for antinociception. However, due to signs of nociceptive response (increased isoflurane requirements and heart rate), and considering the evidence of a predominance of μ receptors in reptiles, we administered low-dose morphine twice during the procedure. Propofol was chosen as an induction agent at a dose sufficient to allow endotracheal intubation. Since reptilians often show apnea in the presence of 100% oxygen, we used a 0.21 oxygen fraction. Despite this, the patient showed respiratory depression. Due to right to left cardiac shunt, sudden changes in the direction of the blood can lead to very rapid changes in the serum concentrations of isoflurane, which leads to frequent oscillations in the anesthetic depth and consequently the need for vaporizer adjustments, which may justify the high expired isoflurane fraction during the procedure. Despite that, physiological parameters were maintained within normal ranges for the species, with slight variations during the surgical procedure. We conclude that the proposed anesthetic protocol is safe for long-duration anesthesia in chelonians, ensuring cardiovascular and respiratory stability. Thus, this report may help veterinarians to perform safe anesthesia in tortoises submitted to invasive surgical procedures. Keywords: testudines, dexmedetomidine, ketamine, butorphanol. Descritores: testudines, dexmedetomidina, cetamina, butorfanol.

The Holdridge life zone approach is a useful tool for planning the territorial management of natural resources as well as for supporting the development of strategies and public policies that result in the definition of priority areas for conservation and sustainable use of forests. Thus, in the present study, we aimed to identify and describe the life zones that occur in the state of Ceará based on the Holdridge model. For this purpose, we used data on annual precipitation, biotemperature and potential evapotranspiration ratio. The results indicated that, although the state of Ceará is mostly under the influence of a semi-arid macroclimate, it presents a heterogeneous geographic space, in which different life zones associated with bioclimatic diversity occur. The most important bioclimatic variable for the classification of life zones was the potential evapotranspiration ratio, which represents the amount of water that is transferred to the atmosphere in relation to the amount of water that is precipitated in a given location. The Holdridge climatic classification identified eight life zones, all located in the tropical latitudinal zone and basal (90.04% of the Ceará territory) and premontane (9.96%) altitudinal zones, which vary, in terms of humidity, from very dry forests to humid forests. The most extensive life zone comprises the transition areas between very dry forest and basal tropical dry forest, occupying 64,825.69 km2, which covers 43.54% of the Ceará territory.

A definição das zonas de vida de Holdridge é uma ferramenta útil para o planejamento da gestão territorial dos recursos naturais, bem como para subsidiar a elaboração de estratégias e políticas públicas que resultem na definição de áreas prioritárias para conservação e uso sustentável das florestas. Desse modo, o presente estudo teve por objetivo identificar e descrever as zonas de vida que ocorrem no estado do Ceará com base no modelo de Holdridge. Para esse propósito, foram utilizados dados de precipitação anual, biotemperatura e relação de evapotranspiração potencial. Os resultados indicaram que, embora o estado do Ceará esteja majoritariamente sob a influência de um macroclima semiárido, apresenta um espaço geográfico heterogêneo, no qual ocorrem diferentes zonas de vida associadas à diversidade bioclimática. A variável bioclimática mais importante para a classificação das zonas de vida foi a relação de evapotranspiração potencial, que representa a quantidade de água que é transferida para a atmosfera em relação a quantidade de água que é precipitada em determinado local. A classificação climática de Holdridge identificou oito zonas de vida em que todas pertencem à faixa latitudinal tropical e abrangem faixas altitudinais basais (90,04% do território cearense) e premontanas (9,96%), que variam em termos de umidade, desde florestas muito secas até florestas úmidas. A zona de vida mais extensa compreende as áreas de transição entre floresta muito seca e floresta seca tropical basal, ocupando 64.825,69 km2, que recobre 43,54% da área total do estado.

Vegetation fires, when not controlled, cause economic disruption, temporary loss of vegetation, and damage to soil, fauna and health. To improve the process of fire prevention and firefighting, it is necessary to evaluate the performance of the involved agents. The objective of this study was to evaluate the firefighting efficiency of vegetation fires in the municipality of Curitiba, Paraná, from 2011 to 2015, using records from the Fire Department of the Military Police of Paraná. Once the consistency of the fire records was verified, they were classified and information was gathered regarding the extent of burnt area, time of first attack, combat time, main fire-extinguishing methods used, and amount of water used. The results indicate that 88% of the records registered a burnt area inferior or equal to four hectares. In addition, the mean burnt area was of 2,399.21 m², the mean attack time was of 14.1 minutes, and the mean combat time was of 29.9 minutes, all lower than the ones presented by studies from different locations. As for the fire-extinguishing methods, it was verified that smothering equipment and water were used in 66.4 and 60.6% of the records, respectively. The mean amount of water used was of 1,186.56 liters per fire, indicating a minimum volume necessary for water storage containers for firefighting in the study area. Based on the results, we concluded that the firefighting of vegetation fires in Curitiba is efficient.

This work aimed to evaluate the lipid oxidation, color, and sensory acceptance of sausages formulated with potassium bixinate (BP) as a substitute for carmine (Car) and sodium nitrite (SNi). Six different treatments (CT—control; CA—40 ppm Car; NIT—150 ppm SNi; C/N—40 ppm Car, and 150 ppm SNi; C/N/B—20 ppm Car, 75 ppm SNi, and 250 ppm BP; and BIX—500 ppm BP) were evaluated along 15 days. BP provided significantly lower levels of lipid oxidation to the samples (C/N/B and BIX) when compared to CT and significantly equal to CA, NIT, and C/N after 15 days (both p < 0.05). BP significantly increased the red (a*) and yellow (b*) intensity of sausages (p < 0.05), providing the highest values in both raw and roasted samples. Sausages formulated with BP did not differ in preference in visual analysis (p > 0.05), and both roasted were preferred over CT (p < 0.05). Although sausages formulated with carmine had better visual acceptance, BIX and C/N did not differ significantly (p > 0.05) after five days. BP was identified in taste analysis; however, it was preferred in the ordination analysis (both p < 0.01). Therefore, the replacement of SNi and Car by BP showed to be a viable alternative.
