Abstract
Bioactive compounds derived from secondary metabolism in animals have refined selectivity and potency for certain biological targets. The superfamily Dendrobatoidea is adapted to the dietary sequestration and secretion of toxic alkaloids, which play a role in several biological activities, and thus serve as a potential source for pharmacological and biotechnological applications. This article constitutes a scoping review to understand the trends in experimental research involving bioactive alkaloids derived from Dendrobatoidea based upon scientometric approaches. Forty-eight (48) publications were found in 30 journals in the period of 60 years, between 1962 and 2022. More than 23 structural classes of alkaloids were cited, with 27.63% for batrachotoxins, 13.64% for pyridinics, with an emphasis on epibatidine, 16.36% for pumiliotoxins, and 11.82% for histrionicotoxins. These tests included in vivo (54.9%), in vitro (39.4%), and in silico simulations (5.6%). Most compounds (54.8%) were isolated from skin extracts, whereas the remainder were obtained through molecular synthesis. Thirteen main biological activities were identified, including acetylcholinesterase inhibitors (27.59%), sodium channel inhibitors (12.07%), cardiac (12.07%), analgesic (8.62%), and neuromuscular effects (8.62%). The substances were cited as being of natural origin in the "Dendrobatidae" family, genus "Phyllobates," "Dendrobates," and seven species: Epipedobates tricolor, Phyllobates aurotaenia, Oophaga histrionica, Oophaga pumilio, Phyllobates terribilis, Epipedobates anthonyi, and Ameerega flavopicta. To date, only a few biological activities have been experimentally tested; hence, further studies on the bioprospecting of animal compounds and ecological approaches are needed.

Abstract
Abstract Amphibian research has grown steadily in recent years in the Amazon region, especially in the Brazilian states of Amazonas, Pará, Rondônia, and Amapá, and neighboring areas of the Guiana Shield. Even so, few data are available for the Amazonian savannas of Brazil. To contribute to the understanding of the diversity of the amphibians of these savannas, we surveyed 15 temporary ponds, six located in open areas, seven on the edge of savanna forest, and two within the forest, in the savanna of the Rio Curiaú Environmental Protection Area (EPA) in Macapá, in the state of Amapá, northern Brazil. Sampling occurred from May 2013 to August 2014 during periods when the ponds contained water. Amphibians were sampled through visual and auditory surveys conducted during both the day- and the nighttime periods on seven days each month over a total of 84 days. A total of 1574 individuals belonging to four families, 12 genera, and 28 species were recorded during the surveys. The cumulative species curve reached the asymptote, indicating that sampling effort was adequate. The number of species was 25% higher than that reported in other studies in Amazonian savannas. Twelve species were recorded for the first time in the savanna of Amapá. Lysapsus boliviana was the most common species (n = 332 of the individuals recorded). The greatest amphibian species richness found in the Rio Curiaú EPA was associated with the savanna mosaic, forest patches, lowland swamp, and temporary ponds. The results of this study contribute to the understanding of the diversity of amphibian species in the Guianan area of endemism in northern Brazil, and also the Amazonian savannas.

Abstract
Polyphenolic compounds present in rosemary were found to have antioxidant properties, anticarcinogenic activity, and to increase the detoxification of pro-carcinogens. The aim of the study was to determine the effect the aqueous extract of rosemary (AER) on mutagenicity induced by methylmethane sulfonate in meristematic cells of Allium cepa, as well as to describe its mode of action. Anti-mutagenicity experiments were carried out with 3 different concentrations of AER, which alone showed no mutagenic effects. In antimutagenicity experiments, AER showed chemopreventive activity in cultured meristematic cells of A. cepa against exposure to methylmethane sulfonate. Additionally, post-treatment and simultaneous treatment using pre-incubation protocols were the most effective. Evaluation of different protocols and the percent reduction in DNA indicated bioantimutagenic as well desmutagenic modes of action for AER. AER may be chemopreventive and antimutagenic.

Abstract
Recently, Physalaemus albifrons (Spix, 1824) was relocated from the Physalaemus cuvieri group to the same group as Physalaemus biligonigerus (Cope, 1861), Physalaemus marmoratus (Reinhardt & Lütken, 1862) and Physalaemus santafecinus Barrio, 1965. To contribute to the analysis of this proposition, we studied the karyotypes of Physalaemus albifrons, Physalaemus santafecinus and three species of the Physalaemus cuvieri group. The karyotype of Physalaemus santafecinus was found to be very similar to those of Physalaemus biligonigerus and Physalaemus marmoratus, which were previously described. A remarkable characteristic that these three species share is a conspicuous C-band that extends from the pericentromeric region almost to the telomere in the short arm of chromosome 3. This characteristic is not present in the Physalaemus albifrons karyotype and could be a synapomorphy of Physalaemus biligonigerus, Physalaemus marmoratus and Physalaemus santafecinus. The karyotype of Physalaemus santafecinus is also similar to those of Physalaemus marmoratus and Physalaemus biligonigerus owing to the presence of several terminal C-bands and the distal localization of the NOR in a small metacentric chromosome. In contrast, the Physalaemus albifrons karyotype has no terminal C-bands and its NOR is located interstitially in the long arm of submetacentric chromosome 8. The NOR-bearing chromosome of Physalaemus albifrons very closely resembles those found in Physalaemus albonotatus (Steindachner, 1864), Physalaemus cuqui Lobo, 1993 and some populations of Physalaemus cuvieri Fitzinger, 1826. Additionally, the Physalaemus albifrons karyotype has an interstitial C-band in chromosome 5 that has been exclusively observed in species of the Physalaemus cuvieri group. Therefore, we were not able to identify any chromosomal feature that supports the reallocation of Physalaemus albifrons.

Abstract
BACKGROUND The taxonomic and phylogenetic relationships of the genus Phyllomedusa have been amply discussed. The marked morphological similarities among some species hamper the reliable identification of specimens and may often lead to their incorrect taxonomic classification on the sole basis of morphological traits. Phenotypic variation was observed among populations assigned to either P. azurea or P. hypochondrialis. In order to evaluate whether the variation observed in populations assigned to P. hypochondrialis is related to that in genotypes, a cytogenetic analysis was combined with phylogenetic inferences based on mitochondrial and nuclear sequences. RESULTS The inter- and intra-population variation in the external morphology observed among the specimens analyzed in the present study do not reflect the phylogenetic relationships among populations. A monophyletic clade was recovered, grouping all the specimens identified as P. hypochondrialis and specimens assigned P. azurea from Minas Gerais state. This clade is characterized by conserved chromosomal morphology and a common C-banding pattern. Extensive variation in the nucleolar organizing region (NOR) was observed among populations, with four distinct NOR positions being recognized in the karyotypes. Intra-population polymorphism of the additional rDNA clusters observed in specimens from Barreiras, Bahia state, also highlights the marked genomic instability of the rDNA in the genome of this group. Based on the topology obtained in the phylogenetic analyses, the re-evaluation of the taxonomic status of the specimens from the southernmost population known in Brazil is recommended. CONCLUSIONS The results of this study support the need for a thorough revision of the phenotypic features used to discriminate P. azurea and P. hypochondrialis. The phylogenetic data presented here also contribute to an extension of the geographic range of P. hypochondrialis, which is known to occur in the Amazon basin and neighboring areas of the Cerrado savanna, where it may be sympatric with P. azurea, within contact zones. The misidentification of specimens may have led to inconsistencies in the original definition of the geographic range of P. azurea. The variability observed in the NOR of P. hypochondrialis reinforces the conclusion that these sites represent hotspots of rearrangement. Intraspecific variation in the location of these sites is the result of constant rearrangements that are not detected by classical cytogenetic methods or are traits of an ancestral, polymorphic karyotype, which would not be phylogenetically informative for this group.

Abstract
We report the case of a patient with a pseudoaneurysm of the ascending aortic clinically diagnosed 5 months after surgical replacement of the aortic valve. Diagnosis was confirmed with the aid of two-dimensional echocardiography and helicoidal angiotomography. The corrective surgery, which consisted of a reinforced suture of the communication with the ascending aorta after opening and aspiration of the cavity of the pseudoaneurysm, was successfully performed through a complete sternotomy using extracorporeal circulation, femorofemoral cannulation, and moderate hypothermia, with no aortic clamping.

Abstract
A crude antigenic preparation of Babesia bigemina was used to develop an ELISA for the detection of IgM antibodies. Optimal dilutions of the antigen, using positive and negative reference sera, were determined by checkerboard titrations. Negative sera from cattle imported from tick-free areas, serum samples collected from infected B. bigemina cattle were used to validate the test. The specificity was 94% and sensitivity of the Elisa 87.5%. Sera from 385 cattle deriving from areas free from tick-borne diseases, which were submitted to a preimmunization process, were screened by this technique. The Elisa detected seroconversion on the 14th day post-inoculation in animals either infested with Boophilus microplus ticks (infected with B. bigemina), or inoculated with B. bigemina infected blood. Antibody titers decreased after day 33; however, all animals remained positive until the end of the experiment (124 days). The ELISA described may prove to be an appropriate serological test for the detection of IgM antibodies against B. bigemina.

Abstract
The endogenous development of Eimeria minasensis was studied in 9 coccidia-free goat kids inoculated with 10(5) sporulated oocysts/kg body weight. Kids were killed 4, 7 (2 animals), 10, 13, 16, 18, 19, and 22 days after inoculation (DAI). In tissue sections of the intestines stained with hematoxylin and eosin and examined by light microscopy, 2 generations of meronts, gamonts, gametes, and oocysts were found. The first generation of meronts developed in cells deep in the lamina propria of the jejunum and ileum. Mature giant meronts (299.4x243.8 microm) found 16 DAI were visible to the naked eye and contained a large number of crescent-shaped merozoites. The second generation of meronts developed in the epithelial cells of crypts of the ileum and above the host cell nuclei. Mature meronts (11.5x10.1 microm) with 18-28 comma-shaped merozoites were first seen 16 DAI. Gametogenesis took place in epithelial cells of the crypts and villi of the terminal part of the ileum, cecum, and colon. Macrogametes (27.8x17.6 microm), mature microgamonts (21.3x17.0 microm), microgametes, and oocysts (30.5x19.4 microm) were found 19 DAI. Sexual stages were below the host cell nucleus.

Abstract
An ELISA test was developed for detecting antibodies against Anaplasma marginale in bovine sera. Four antigenic preparations were produced from infected red blood cells. Some aliquots of this preparation were stored at -70 degrees C with 30% DMSO in phosphate-buffered saline (PBS) and others were lysed with 0.9% NH4Cl and stored at -20 degrees C. Typical anaplasmal structures were seen by electron microscopy in the antigenic preparations containing the erythrocytes that had been stored with DMSO. The performance of the ELISA test was evaluated by testing 298 positive serum samples collected from immunized cattle, 39 negative serum samples collected from cattle imported from areas free of A. marginale and 50 samples collected from cattle naturally infected in the field. The test gave a specificity of 94.87% and a sensitivity of 100%.

Abstract
Eimeria minasensis n. sp. is described in the domestic goat Capra hircus from Brazil. Oocysts ellipsoidal are 35 x 24.5 (32-37.7 x 20.9-27.9) microns. Sporocysts elongate-ellipsoid are 15.2 x 9 (12.3-18.4 x 7.8-10.2) microns, with a Stieda body at the narrow end. Oocyst wall smooth and bilayered; outer layer about 1.2 (0.8-1.6) microns and colorless; inner layer about 0.5 (0.4-0.8) micron and dark-brown. Micropyle, a mound-shaped micropylar cap 1.6 x 8.9 (0.8-2 x 7-10.2) easily dislodged; one or more oocyst polar granules present. Oocyst residuum absent. Sporocyst residuum present, composed of many scattered granules. Sporozoites elongate, lying lengthwise, "head to tail" in the sporocysts; one or two refractile globules are usually visible. Sporulation time was 120 hr at 27 degrees C, prepatent period, 19 to 20 days and patent period 15 to 25 days. Gamonts, gametes and oocysts present in cecum and colon. Prevalence was 12.8% (6/47) in goats from Minas Gerais, Brazil.

Abstract
The development of Babesia equi in salivary glands of adult female Boophilus microplus was observed under a light microscope using semithin sections stained with toluidine blue. Engorged nymphs were obtained from splenectomized foals experimentally infected with B. equi. As adults, they were then fed on rabbits for 5 days and the salivary glands of manually collected individuals were removed at intervals of 24 h. Sporozoites were found in type III granular acini cells between the 2nd and 5th days following feeding on the rabbits. Sporoblasts and sporozoites were observed in the same or adjacent acini cells in all the glands examined. The formation of the sporozoites occurred following the multiple division of the sporoblasts through a process of radial budding from the periphery of bodies resulting from multiple fission. Sporozoites were detected in smears of adult males stained with Giemsa, between the 2nd and 5th days following feeding by the ticks. Adults of B. microplus, fed during the nymphal phase on foals with patent parasitemia, transmitted sporozoites of B. equi to a splenectomized foal. The role of B. microplus in the transmission and epidemiology of B. equi is discussed.

Abstract
The development of Babesia equi was studied in the salivary glands of adult female ticks, Boophilus microplus, using a transmission electron microscope (TEM). Engorged nymphs were obtained from splenectomized foals experimentally infected with B. equi and fed in the adult phase for 5 days on rabbits. Sporogony in B. equi involves the development of sporoblasts and sporozoites, which form from finger-like projections on the surface and through radial budding. Mature sporozoites (2.0 x 1.1 microns), typically pyriform, showed a polar ring, rhoptries, micronemes, nuclei, and mitochondria, and a high concentration of free ribosomes were observed from the 2nd day of the ticks, feeding on the rabbits. In general, sporogony of B. equi in the salivary glands of B. microplus showed similarities to the development of this parasite in species of Hyalomma, although with some significant differences in the sporozoite's dimensions. The results of this study indicate that B. equi is capable of multiplying in the salivary glands of adult female B. microplus, forming sporozoites with specialized organelles characteristic of the invasive form, and suggest that B. microplus can act as a natural vector of B. equi in endemic areas where there is no other probable source of infection or where it is the only tick species present on horses.

Abstract
The endogenous development and prepatent and patent periods of Eimeria ninakohlyakimovae were studied in 43 1-3-wk-old coccidia-free kids inoculated with 5.0 x 10(4), 1.5 x 10(5), 2.0 x 10(5), or 9.0 x 10(5) sporulated oocysts/kg. Twenty-five kids were killed at 24- or 48-hr intervals, 2-18 days after inoculation (DAI). Two generations of meronts, gamonts, gametes, and oocysts were found in sections stained with hematoxylin and eosin and examined using under light microscopy. The first generation of meronts developed in the endothelium of the lacteals, in the lamina propria, and in the lymphatic vessels of the ileum submucosa. Mature, first-generation meronts, 165.5 x 123.6 microm, were first found 10 DAI. Second-generation merogony developed in the crypt epithelial cells of the cecum and colon; mature meronts, 16.8 x 11.6 microm, were first seen 12 DAI. Gametogenesis occurred in the cecum and colon epithelium; mature microgamonts (16.1 x 13.0 microm), microgametes, macrogametes (14.7 x 12.5 microm), and oocysts (18.3 x 13.3 microm) were seen at 13 DAI. The course of the infection was followed in 18 kids examined every day until 24 DAI. The prepatent period was 14.7 (13-17) days and the patent period 6.8 (4-10) days. The sporulation time at 30 C, with constant aeration, was 2-3 days.

Abstract
The ultrastructure of endogenous stages of Eimeria ninakohlyakimovae was observed in epithelial cells of cecum and colon crypts from a goat experimentally infected with 2.0 x 10(5) oocysts/kg. The secondary meronts developed above the nucleus of the host cell. The nucleus first divides and merozoites then form on the surface of multinucleated meronts. Free merozoites in the parasitophorous vacuole present a conoid, double membrane, one pair of rhoptries, micronemes, micropore, anterior and posterior polar ring, a nucleus with a nucleolus and peripheral chromatin. The microgamonts are located below the nucleus of the host cell and contain several nuclei at the periphery of the parasite. The microgametes consist of a body, a nucleus, three flagella and mitochondria. The macrogamonts develop below the nucleus of the host cell and have a large nucleus with a prominent nucleolus. The macrogametes contain a nucleus, wall-forming bodies of type I and type II. The young oocysts present a wall containing two layers and a sporont.

Abstract
An outbreak of cryptosporidiosis is reported among 22 suckling kids aged one to two weeks which were maintained for experimental purposes at the veterinary hospital of the University of Minas Gerais. They were divided into three groups. Group A consisted of 10 animals with acute diarrhoea; initially their faeces were pasty but later they were excreted in watery streams. The animals were treated with gentamicin and fluid therapy but did not respond to treatment and died within a week. Postmortem examination revealed liquid intestinal contents, enlarged mesenteric lymph nodes, and hyperaemia and haemorrhage were observed in the final third of the small intestine of some of the animals. Of the 10 animals in group B four had diarrhoea and six were normal; postmortem examination showed that the macroscopic changes were similar to those observed in group A. Three of the animals with diarrhoea had a massive Cryptosporidium infection in the final third of the small intestine, caecum and colon. Four of the six normal animals had a moderate Cryptosporidium infection in the same organs. The two kids in group C died; they had pasty faeces, and there were many Cryptosporidium oocysts in the faecal smears.

Abstract
Tissue cysts of Besnoitia sp. were found in muscles and several organs from a naturally infected Akodon montensis captured in the rural area of the municipality of Timbó, Santa Catarina State, in southern Brazil. Indirect fluorescence and enzyme-linked immunosorbent assays carried out with sera from mice chronically infected with Toxoplasma gondii and Besnoitia sp. showed, as expected, a stronger reaction against homologous than heterologous antigens. No cross-protection was observed in mice immunized with T. gondii when challenged with Besnoitia sp. This is the first description of a natural infection of A. montensis by parasites of the genus Besnoitia sp. in Brazil.

Abstract
Morphology and development of Anaplasma marginale were studied in midgut epithelial cells of adult Boophilus microplus females using light and transmission electron microscopy. Hemoparasite-free B. microplus larvae were used to infest Holstein calves experimentally inoculated with A. marginale. When A. marginale parasitemia varied from 0.4% to 4.3%, 140 engorged female ticks were collected and kept individually in steel wire tubes and incubated outdoors on Brachiaria decumbens grass pasture. Female ticks in groups of 20 were dissected 14, 19, 26, 33, 40, 47 and 50 days after detachment. Engorged female ticks collected from an A. marginale-free calf were kept under the same conditions as control ticks. Gut sections of infected and control ticks were processed using light and electron microscopy. Infected gut sections were processed by the immunocytochemical peroxidase-antiperoxidase technique. Under light microscopy A. marginale colonies were found in midgut epithelial cells of engorged B. microplus females from 19 days on after detachment from donor calves. Colonies were 6.1-10.3 microns in diameter, ovoid or irregular and contained round or shaped organisms. Two distinct morphological types of colonies (BM1 and BM2) were found. BM1 colonies had a dense matrix strongly stained in which organisms were barely visible; BM2 had large separated organisms densely stained inside a matrix which was lightly stained. A. marginale colonies immunocytochemically stained were found in gut tissue sections using light microscopy. Using transmission electron microscopy organisms of different morphologies were found in midgut epithelial cells of engorged females, suggesting sequential phases of development of A. marginale in the vector. Modifications occurred in colonies and in the organisms within them. No symbiotic rickettsiae were found in intestinal cells of control ticks.

Abstract
The endogenous development of Eimeria christenseni was studied in 10 two-to four-week-old kids inoculated with 10(6)-10(7) sporulated oocysts. They were killed at intervals from two to 26 days after inoculation, and their tissues were examined for endogenous stages of the coccidian by light microscopy. Such stages were found in the small intestine and mesenteric lymph nodes. In the sexual cycle, two generations of meronts were found. The first generation developed in endothelial cells of lacteals in the jejunum In the sexual cycle, two generations of meronts were found. The first generation developed in endothelial cells of lacteals in the jejunun and ileum and mesenteric lymph nodes, and mature meronts were first seen 14 days after inoculation. The second generation developed in epithelial cells of the glands of Lieberkuehn in the jejunum and ileum and in mesenteric lymph nodes, and its mature meronts were first seen by 16 days. Sexual stages were present mostly in epithelial cells of the tips and sides of the villi and less frequently in crypt cells of the jejunum and ileum. Mature macrogametes and microgamonts and oocysts were also first seen by 16 days. The prepatent period was 17(14-23) days; the patent ranged from 8 to more than 30 days. Sporulation time was 3-4 days at 30 degrees C. E. christenseni was found to be pathogenic, kids inoculated with 1-5 X 10(5) sporulated oocysts exhibited the following signs: severe diarrhea, anorexia, polydipsia, poor hair coat, and extreme weakness. They recovered about a month later, but their growth rates appeared to be lower than those of uninoculated animals kept under the same conditions. One kid died 20 days after inoculation with 10(7) oocysts.

Abstract
With the purpose of obtaining pro-drugs of dapsone and sulfadimethoxine, those chemotherapeutic agents were attached through covalent bonding to starch polymeric dialdehyde (Sumstar-190). The antimalarial activity of the two resulting compounds - the dapsone saccharidic polymer (PS6) and the sulfadimethoxine saccharidic polymer (PS7) - in mice experimentally inoculated with Plasmodium berghei was significantly increased with this molecular modification. Mice infected with malaria and kept without treatment together with others which received different doses of PS6 and PS7 were also partially or totally cured, possibly due to the ingestion of excrements containing the parent chemotherapeutic agents.

Abstract
Calves aged 3 months were readily infected with oocysts and cysts of Toxoplasma gondii administered by oral route. Fever, respiratory distress, nasal discharge and hyperemia of the conjunctivas were the most significant clinical signs noted in the infected animals. Parasitemia was demonstrated in all infected calves. It occurred on different days and up to 62 days after the infection. Toxoplasma was demonstrated in tissues of all infected calves, and the organ most frequently parasitized was the lymph node. Parasitism of the retina was demonstrated in two calves. All infected animals had antibody against T. gondii in their serum. The Sabin-Feldman dye test and the indirect immunofluorescent test were both useful in detecting antitoxoplasma antibody.
