The aim of this study was to evaluate the resistance of Acinetobacter spp. isolated from patients with pneumonia in a Brazilian Pre-Amazon region during the pre-pandemic and pandemic periods of COVID-19. Bacterial strains were obtained from tracheal aspiration, sputum and bronchoalveolar lavage for diagnosis and phenotypic characterization. MALD-TOF was used to identify strains. The automated Phoenix and VITEK® 2 Compact system and the disc diffusion method were performed to determine the antimicrobial susceptibility profile. Were analyzed a total of 41,590 samples from patients admitted to hospitals of a Brazilian Pre-Amazon region, from January 2019 to December 2021. Of these, 162 isolates of Acinetobacter spp. were from the pre-pandemic period and 308 from the pandemic COVID-19. A. baumannii was the most prevalent species. Among the samples, 52% were male patients, aged over 60 years, hospitalized in intensive care units. Acinetobacter spp. showed higher rates of resistance to cefepime (79.1%), levofloxacin (77.8%), and ceftazidime (77%) in the pre-pandemic period and during the pandemic to piperacillin (72.4%), imipenem (71.6%) and ciprofloxacin (71.8%). Taken together, the data showed that A. baumannii was the most prevalent species among Acinetobacter spp., being more frequent among elderly patients admitted to the ICU. The strains presented high resistance to most antibiotics tested, mainly carbapenems. In addition, there was an increase in resistance to polymyxin B, which raises an alert since this is a therapeutic choice to treat infections caused by Acinetobacter spp. multidrug resistant.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"84 ","pages":"e279691"},"PeriodicalIF":0.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected from four informants through semi-structured questionnaires, addressing aspects of captive breeding of wild birds. Three species were recorded: Sporophila angolensis, S. bouvreuil and Sicalis flaveola. The species are kept mainly because of the beauty of their songs and the potential for their use in rinhas (bird fighting), factors also responsible for the commercialization of the species. The aspects involved in maintenance vary among breeders and according to interspecific factors. However, the selection and reproduction of the species are related to behavioural factors (singing ability and potential for rinhas). The data show that the breeding and management of wild birds is a complex activity in a socio-cultural and economic context, with more studies required to understand the dynamics involved in this process including whether or not these forms of management interfere with the genetics of the birds species through the artificial selection process.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"84 ","pages":"e285304"},"PeriodicalIF":0.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have conducted studies to investigate bacterial strains for their probiotic potential. Like other animals, fish also have several bacterial strains in their gut that possess probiotic properties, although this is limited to Bacillus species. Therefore, this study aimed to isolate and characterize probiotic Bacillus species from the gut of Masheer fish (Tor Puititora). Four pure bacterial isolates were selected as potential probiotic strains based on selection criteria, including survival rate in acid and bile salt. The isolates exhibited significant antimicrobial activity against pathogenic bacteria, including Escherichia coli (ATCC8739), Pseudomonas aeruginosa (ATCC9027), and Staphylococcus aureus (ATCC6538). MF2 and MF3 demonstrated clear zones, including antimicrobial activity against all three indicator pathogens. MF1 and MF4 exhibited antimicrobial activity against E. coli (ATCC8739) and P. aeruginosa (ATCC9027). Furthermore, the 16S rRNA gene sequences of all isolates exhibited a close association with Bacillus tequilensis (KCTC13622), with nucleotide similarity of 98.63%, 98.25%, 98.80%, and 98.35%, respectively.

These functions are depending on glandular maturation and testosterone-androgen receptor (AR) dependent actions. Since tyrosine phosphorylated (TyrPho) proteins, also important for secreting pathways, have been localized in the androgen dependent organs, association between AR and TyrPho protein expressions in prostate is still unknown. This study aimed to investigate the changes of such proteins in prostate gland of male castrated rats. Nine prepubertal and adult twenty-two adult male rats were divided into the prepubertal (Pre, n=9), Sham (n=6), castrate for 3 (Cas-3, n=8) and for 7 (Cas-7, n=8) days groups, respectively. Serum testosterone level was determined. Histology and AR localization in each prostatic lobe were observed. TyrPho and AR protein expressions were also examined. The results showed undetectable testosterone level and low AR expression in Pre and Cas prostates with the decreased size. Few histopathologies were found in Cas groups. In ventral lobe, a Tyrpho protein was increased at the 48 kDa but the 52, 33, and 26 kDas were decreased in the Pre and Cas groups. For dorsolateral lobe, they were decreased at 33 and 30 kDas in Pre group and only 30 kDa was decreased in Cas-3 group. In the anterior lobe, the TyrPho proteins 57, 49, 39, 30, and 26 kDas were decreased in Pre group while 57, 30, and 26 kDas were decreased in Cas-3 group. In conclusion, the alterations of testosterone level and AR expressions associate with TyrPho protein expressions in prostate gland during development.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"84 ","pages":"e285484"},"PeriodicalIF":0.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For other strains the results revealed that the maximum zone against B. subtilis was 5.7mm at 121 °C and for Staph. aureus it was 6.6mm at 80 °C. By observing the results by changing pH it was observed that MIC produced against B. cereus was 6.2mm at 7pH, against B. subtilis zone of inhibition was 7.2mm at 5pH, for E.coli it was 5.4mm at 3pH. Means of all the variable results of different (concentration, pH and temperature) were compared by using one way ANOVA.
