Kulturelna i metagenomska identifikacija mikrobioma kod supkliničkog mastitisa u krava.

Metagenomic and traditional microbial culture based analyses of milk samples from cows harbouring subclinical mastitis pathogens were carried out to identify the microbial community structure of milk. A total of 77 Triple cross (TP), Kankrej and Gir lactating cows and 301 quarters were screened for subclinical mastitis. A total of 106 isolates belonging to five different microbial genera were recovered from 91 quarters of 41 cows, including 15 quarters having mixed bacterial infections by cultural examination. Pyrosequencing readings obtained from the breed wise pooled DNA of subclinical mastitis milk samples were analyzed using the SEED subsystem database of Meta Genome Rapid Annotation with Subsystem Technology (MG-RAST). Among the five genera, Staphylococcus, Streptococcus, Micrococcus, Bacillus and Escherichia, detected in the subclinical mastitis milk samples by culture based methods, four genera, Staphylococcus, Streptococcus, Bacillus and Escherichia, were identified in the corresponding pyrosequencing data, while Micrococcus was not found. In contrast, the pyrosequencing yielded 28 bacterial species, of which only two species, S. aureus and E. coli, were identified by the cultural method. S. agalactiae, the third species identified by cultural method, was not found in the pyrosequencing data. Metagenomic analysis additionally identified 19 genera and 26 species in comparison with the routine cultural methods. Many of the fastidious / anaerobic bacterial organisms, which are difficult to cultivate by routine methods, were identified by metagenomic analyses.Radi identifikacije mikrobne zajednice u mlijeku provedena je metagenomska i uobičajena kulturelna pretraga uzoraka mlijeka krava sa supkliničkim mastitisom. Ukupno je 77 trostruko križanih Kankrej i Gir mliječnih krava i 301 četvrt vimena bilo pretraženo na supklinički mastitis. Izdvojeno je bilo 106 izolata svrstanih u pet različitih rodova iz 91 četvrti od 41 krave uključujući i 15 četvrti kod kojih je kulturelnom pretragom bila ustanovljena mješovita bakterijska infekcija. Sljedovi mješavine DNA izdvojeni iz uzoraka mlijeka kod supkliničkog mastitisa očitani pirosekvenciranjem bili su analizirani po podsustavu SEED baze podataka „Meta Genome Rapid Annotation with Subsystem Technology (MG-RAST)“. Iz pretraženih uzoraka mlijeka bilo je izdvojeno pet rodova: Staphylococcus, Streptococcus, Micrococcus, Bacillus i Escherichia. Četiri su bila dokazana postupkom pirosekvenciranja: Staphylococcus, Streptococcus, Bacillus i Escherichia, dok Micrococcus nije bio dokazan. S druge strane, pirosekvenciranjem je bilo dokazano 28 bakterijskih vrsta, od kojih su samo dvije, S. aureus i E. coli, bile dokazane klasičnom kulturelnom pretragom. S. agalactiae, treća vrsta identificirana kulturelnom pretragom nije bila dokazana postupkom pirosekvenciranja. Metagenomskom analizom dodatno je bilo dokazano 19 rodova i 26 vrsta u usporedbi s rutinskom kulturelnom pretragom. Mnoge anaerobne bakterije, koje je vrlo teško uzgojiti rutinskim metodama, bile su identificirane metagenomskom analizom

Convalescent plasma in patients admitted to hospital with COVID-19 (RECOVERY): a randomised controlled, open-label, platform trial

SummaryBackground Azithromycin has been proposed as a treatment for COVID-19 on the basis of its immunomodulatoryactions. We aimed to evaluate the safety and efficacy of azithromycin in patients admitted to hospital with COVID-19.Methods In this randomised, controlled, open-label, adaptive platform trial (Randomised Evaluation of COVID-19Therapy [RECOVERY]), several possible treatments were compared with usual care in patients admitted to hospitalwith COVID-19 in the UK. The trial is underway at 176 hospitals in the UK. Eligible and consenting patients wererandomly allocated to either usual standard of care alone or usual standard of care plus azithromycin 500 mg once perday by mouth or intravenously for 10 days or until discharge (or allocation to one of the other RECOVERY treatmentgroups). Patients were assigned via web-based simple (unstratified) randomisation with allocation concealment andwere twice as likely to be randomly assigned to usual care than to any of the active treatment groups. Participants andlocal study staff were not masked to the allocated treatment, but all others involved in the trial were masked to theoutcome data during the trial. The primary outcome was 28-day all-cause mortality, assessed in the intention-to-treatpopulation. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936.Findings Between April 7 and Nov 27, 2020, of 16 442 patients enrolled in the RECOVERY trial, 9433 (57%) wereeligible and 7763 were included in the assessment of azithromycin. The mean age of these study participants was65·3 years (SD 15·7) and approximately a third were women (2944 [38%] of 7763). 2582 patients were randomlyallocated to receive azithromycin and 5181 patients were randomly allocated to usual care alone. Overall,561 (22%) patients allocated to azithromycin and 1162 (22%) patients allocated to usual care died within 28 days(rate ratio 0·97, 95% CI 0·87–1·07; p=0·50). No significant difference was seen in duration of hospital stay (median10 days [IQR 5 to >28] vs 11 days [5 to >28]) or the proportion of patients discharged from hospital alive within 28 days(rate ratio 1·04, 95% CI 0·98–1·10; p=0·19). Among those not on invasive mechanical ventilation at baseline, nosignificant difference was seen in the proportion meeting the composite endpoint of invasive mechanical ventilationor death (risk ratio 0·95, 95% CI 0·87–1·03; p=0·24).Interpretation In patients admitted to hospital with COVID-19, azithromycin did not improve survival or otherprespecified clinical outcomes. Azithromycin use in patients admitted to hospital with COVID-19 should be restrictedto patients in whom there is a clear antimicrobial indication

Notes on the Eastern Comma Polygonia c-album agnicula Moore, 1872 (Lepidoptera: Nymphalidae: Nymphalinae) from Tawang District, Arunachal Pradesh, India

The Comma, Polygonia c-album ranges across W.Himalaya up to Sikkim-Bhutan but not reported from North East India. Altogether, three subspecies occur within Indian region.This sighting is not surprising as Tawang dist. shares boundary with Bhutan. This sighting shows that more survey is needed in W. Himalaya to know the butterfly fauna of the region.</div

Formulation consideration and characterization of microemulsion drug delivery system for transnasal administration of carbamazepine

The purpose of the present study was to formulate and characterize carbamazepine loaded microemulsion and mucoadhesive microemulsion drug delivery system for its intranasal administration. Carbamazepine microemulsion and mucoadhesive microemulsion were prepared by titration method. The drug-loaded microemulsions were successfully prepared which contain 6% Labrafil M 1944 CS as an oily phase, 32% surfactant mixture of Cremophor RH 40: Transcutol P (4:1) and 62% (wt/wt) aqueous phase. Microemulsion formulation which displayed an optical transparency of 99.95%, globule size of 34.32 ± 1.09 nm, and polydispersity index of 0.127 ± 0.012 was selected for the incorporation of mucoadhesive component. The drug-loaded mucoadhesive microemulsion that contains 0.5% wt/wt of polycarbophil displayed higher in vitro mucoadhesive potential (21.0 ± 3.0 min) and diffusion coefficient (0.3172 ± 0.03) than microemulsion. All formulations were found free from nasal ciliotoxicity and stable for 6 months
