Abstract

Lactoferrin is an 80 kDa glycoprotein which has advantages in biological activity as an antimicrobial, antibacterial, antiviral, antiparasitic, and immunomodulatory agent. Advances in recombinant technology have made it possible to produce lactoferrin proteins on a large scale, the production of recombinant lactoferrin can be carried out in various expression systems. Escherichia coli is one of the hosts in expression systems that are widely used in the production of recombinant proteins. The recombinant protein lactoferrin is produced by insertion of the bovine lactoferrin gene in the plasmid pET 11-a. The bovine lactoferrin gene that has been inserted into the plasmid pET, transformed and expressed in the cell host of E. coli BL21. The bovine lactoferrin protein expression was induced by the addition of a chaperone one of the coexpressions, which accompanied the E. coli synthesis system to achieve the desired protein expression. The expression of pET11a - Bovlacto plasmid in E. coli was supported by the inducer L-arabinose and IPTG. The bovine lactoferrin gene embedded in the recombinant plasmid pET-11a was able to be well expressed in E. coli BL21 with the hybridization signal in the dot blot method test and the target specific band, namely in the 80-85 kDa position range of SDS-PAGE electrophoresis results.

Abstract

Background: Single Nucleotide Polymorphisms (SNPs) of the Transcription Factor 7-Like 2 (TCF7L2) diabetes susceptibility gene were located in the noncoding region. Intronic SNP may play a role in mRNA splicing. This study aimed to elucidate whether SNPs of the TCF7L2 gene expressed different mRNA isoforms in the peripheral blood. Methods: Across sectional study was conducted in Legian Bali. A total of 56 subjects were grouped into carrier of TCF7L2SNPs (28 Balinese age 30-74 years,eitherheterozygote or mutant of the rs12255372 SNP [GT or TT], rs7903146 [CT or TT], and rs10885406 [AG or GG])and wild-type of TCF7L2 (28 matched in age and sex Balinese,rs12255372 [GG], rs7903146 [CC], and rs10885406 [AA])which has been identified in the previous study.In this study, the mRNA isolation was done using LS Trizol reagent (Nitrogen®) and variants of the mRNA isoform in the TCF7L2 gene was identified by reverse transcriptase-polymerase chain reaction (RT-PCR) method, using two pairs of overlapping primer.The first primer PCR products were grouped into Group-A, Group-B, Group-C and Group-D. The second primer PCR products were grouped into Group-a, Group-b, Group-c and Group-d. Oral glucose tolerant test (OGTT) was done to both groups.Blood samples were taken during fasting, at 1 hour and 2 hours after the oralglucose load, for blood glucose, and insulin level measurement. Results: There were seven pairs of the group combination including group A-a, A-c, A-d, C-a, C-c, C-dand D-c, and group C-c was the most commonly found among all subjects in this study (42.3%). Subjects with diabetes risk allele were 2.66 times more likely to express group C-ccompared to subjects without diabetes risk allele of SNPs in the TCF7L2 gene (95%CI 1.24–5.72 p=0.011). Mean response of insulin increment after oral glucose load among group C-c was higher compared with the non-group C-c, 84.63±41.01 vs. 62.02±38.09ng/ml (mean difference 22.61 95%CI 0.41–44.80 p=0.046). However, blood glucose level, fasting insulin, HOMA %B and HOMA IR were similar between the two groups. Conclusion: Variants of TCF7L2 gene expressed different mRNA isoformsin the peripheral blood.Compared to subjects without diabetes risk allele of SNPs in the TCF7L2 gene, subject with diabetes risk allele expressed dominant variant isoform mRNA 2.66 timeshigher.The higherresponse of insulin increment after oral glucosewas observedin the dominant variant which may reflectthe early condition of insulin resistant.Keywords: Diabetes, SNP TCF7L2, isoforms mRNA.

Abstract

Streptococcosis cause by Streptococcus suis is an important bacterial disease because it has zoonotic potential and is capable of causing serious outbreaks in both pigs and humans. The main symptoms are meningitis, deafness, inflammation of the eyes to blindness. This study aims to find the presence of S. suis bacteria infection on slaughtered pigs in Denpasar. A total of 200 pig tonsils were taken as samples with 20 sampling times. Each sampling was taken 10 samples. The samples were grown on 5% sheep blood agar then followed by Gram staining, oxidase, coagulase, and catalase test. Suspected positive results in each collection were continued with the Polymerase Chain Reaction primers SSRecN-F and SSRecN-R tests. The results of testing on 200 samples of pig tonsils showed that 2.5% of samples were positive for S. suis. Based on the results of the study, it can be concluded that the sample of pig tonsils from the pig slaughterhouse in Denpasar was infected with S. suis.

Abstract

BACKGROUND Streptococcus suis is the most frequent etiology of zoonotic bacterial meningitis, potentially initiating an outbreak. Acute bacterial meningitis caused by S. suis has various manifestations, often accompanied by sepsis with multiple organ involvement. This study aimed to evaluate the pattern of S. suis outgrowth in the brain, which is associated with nuclear factor-κappaB (NF-κB) activation, neutrophil extracellular traps (NETs) release (NETosis), and microglial activation as three crucial pathological mechanisms of bacterial meningitis. METHODS This study used 64 female BALB/c mice aged 6 weeks and weighed 18−20 g, grouped into infected and non-infected as the control group. Both groups were administered 1 ml of S. suis serotype 2 suspension (1 × 107 colony forming-unit/ml) and normal saline intraperitoneally. The bacterial colony count of S. suis was evaluated, along with NF-κB and NET levels in blood and brain, as well as meningeal inflammation and microglial activation in the brain at Days 1, 3, 5, and 7 post-infection. RESULTS The invasion of S. suis into the brain slightly induced NF-κB activation, leading to a burst of inflammatory responses, neutrophil infiltration with NET releases, and microglia activation that co-occurred, showing their peaks on Days 3 and 5 after onset. CONCLUSIONS The S. suis invasion into the mice’s brain increased NF-κB activation, NETosis, and microglia activation during S. suis meningitis infection.

Abstract

Sensorineural deafness as a result of Streptococcus suis (S. suis) meningitis is a serious hazard to worldwide public health and one of the strategic study concerns in neuroscience. There is currently no treatment plan for sensorineural deafness brought on by S. suis meningitis that can significantly enhance quality of life. Controlling S. suis meningitis-related sensorineural deafness is therefore vital for the area of neurology. This review of the literature seeks to provide an overview of the scientific literature on the epidemiology, etiology, and features of deafness as they pertain to sensorineural hearing loss brought on by S. suis meningitis. Spiral Ganglion Neurons, hair cells in the cochlea, and brain-derived neurotrophic factor in the peripheral auditory system interact with one another in the etiology of sensorineural deafness, according to recent studies.

Abstract

Coccidiosis, also commonly referred to as bloody diarrhea, is caused by Eimeria spp. and primarily affects the digestive tract. The most pathogenic Eimeria species in chickens are Eimeria tenella and Eimeria necatrix. The subject of this case study was a 27-day-old female broiler chicken from a commercial farm located in Tunjuk Village, Marga Subdistrict, Tabanan Regency, Bali. The chicken had been reported to suffer from bloody diarrhea for five days, accompanied by clinical signs of weakness, anorexia, pale comb, ruffled feathers, and a tendency to huddle in the corner of the pen. This case study aimed to describe the anatomical pathology, histopathology, and laboratory findings to obtain a definitive diagnosis of the disease affecting this chicken. The results of the anatomical pathology examination showed hemorrhage in the cecum. Histopathological examination of the cecum revealed the presence of schizonts, hemorrhage, and inflammatory cell infiltration. Qualitative fecal examination confirmed the presence of Eimeria spp. oocysts, while quantitative fecal examination using the McMaster technique revealed 895,600 oocysts per gram of feces, indicating a severe infection. Based on clinical observations, epidemiological data, gross pathological changes, histopathological findings, and fecal examinations using native, sedimentation, flotation, and McMaster methods, it was concluded that the chicken was affected by coccidiosis.
