Investigating The Virulent Genes and Antibiotic Susceptibility Patterns of V. Cholerae O1 in Environmental and Clinical Isolates in Accra

ABSTRACT Background: Cholera has been endemic in Ghana, since it was first detected in 1970. Outbreaks have often started in slums of the city especially Accra. In spite of the overwhelming nature of cholera outbreak that has resulted in high mortality and morbidity, there is little information on the reservoir of the causative agent. It has however, been shown that long-term survival of the bacteria may be attained in watery environments or in humans with no signs of cholera. Consequently, ...

Reverse Engineering for Artificial Intelligence to Prevent Healthcare of Human Brain

Abstract The world's first artificial brain is known as the "Blue Brain." A virtual machine is a computer that can perform the functions of a nervous system with Artificial Intelligence. Reverse engineering is a popular method of simulating the human mind on a molecular basis. Therapy of cognitive impairment, academic interest in awareness and the human healthcare condition, a lower part method to creating thinking machines, and archives of all neuroscience research findings and associated pr...

Diversity Of Extended-Spectrum Beta-Lactamase Genes In Avian Pathogenic Escherichia Coliin Scavenging Local Chicken In Morogoro Municipality, Tanzania

ABSTRACT The poultry industry, especially chicken production has in recent times faced a major setback due to devastating effects of Extended Spectrum Beta-Lactases (ESBL) producing organisms.This research aimed at investigating the diversity of ESBL genes in avian pathogenic Escherichia coli(APEC) among scavenging local chickens. A total of 400 cloacal and oropharyngeal swabs were obtained, out of which 192 Escherichia coli were isolated. By use of virulence factor profiling, these 192 samp...

Association Of Betaine Aldehyde Dehydrogenase 2.1 (Badh2.1) Gene Allele With Aroma In Popular Traditional Rice Varieties In Tanzania

ABSTRACT Aromatic rice is highly cherished in many countries of the world and commands premium prices at all levels of the global rice trade. The presence of aroma in aromatic rice is controlled by betaine aldehyde dehydrogenase 2.1 (BADH2.1) gene allele which results from an eight base pair deletion and three single nucleotide polymorphisims (SNPs) in exon seven of betaine aldehyde dehydrogenase 2 (BADH2) gene. This mutation is responsible for the introduction of premature stop codon which ...

Molecular Epidemiology Of Leptospira Species Among Agropastoral Communities Living In Katavi-Rukwa Ecosystem, Tanzania

ABSTRACT Leptospirosis is an emerging zoonotic infectious disease that affects humans and animals worldwide as it causes febrile illness in humans. The disease has been reported in a number of human-livestock-wildlife interfaces of Northern and Eastern Tanzania. Very little is known of many zoonotic disease conditions in the research naive areas of Western and Southern Tanzania. This study aimed at detecting the prevalence of Leptospira species among agro-pastoralists at the human-animal int...

Genetic diversity of rice (oryza sativa l.) Landraces conserved at the national genebank as revealed by simple sequence repeat (ssr) dna markers

EXTENDED ABSTRACT  There is high degree of rice diversity in Tanzania. Increased human population pressure and activities has caused the population of wild rice to disappear at alarming rate. NPGRC collected over 125 accessions of rice landraces and 7 wild relatives for conservation and sustainable utilization in improvement programs, but no morphological or genetic diversity study that have been done to support any future collections. An investigation was conducted to determine the extent o...

Relationship Between Assembly Behavior And Molecular Responses In Foveal Gland Of Unfed And Fed Adult Rhipicephalus Appendiculatus

ABSTRACT Ixodid ticks respond to a limited spectrum of stimuli in their search for hospitable environments, hosts and mates hence change in their behavior. This responsiveness is mediated by pheromones which are signaled by biochemical changes that occur during different stages of feeding. Genes induced during blood feeding result in the expression of new proteins secreted into tick foveal gland. Some of these proteins may be involved in the biosynthesis of these pheromones. Assembly behavior...

Assessment Of Genetic Diversity Of Maize Landraces In Tanzania Using Random Amplified Polymorhic Dna Markers

ABSTRACT  The knowledge and comprehension of the genetic variation of maize (Zea mays L.) landraces is pivotal for the implementation of measures to address conservation and improvement. The purpose of this study was to assess the genetic diversity and relationship among selected maize genotypes in Republic of Tanzania by screening twenty Random Amplified Polymorphic DNA molecular markers.DNA was extracted from 160 maize genotypes and PCR was conducted using twelve informative primers. Ampli...

Detection Of Arenaviruses In Rodents, Shrews And Elephant Shrews From Selected Wildlife-Human Interfaces In Tanzania

ABSTRACT  The present study was conducted to investigate the presence of Arenaviruses from rodents, shrews and elephant shrews captured in selected wildlife-human interfaces in Tanzania. The study involved six sites with high potential for contact between wildlife and humans namely; Ruaha, Kilombero, Mtwara, Mbeya, Mbinga and Mikumi. A total of 121 animals comprising 111 rodents, 3 shrews and 7 elephant shrews were screened for Arenaviruses using conventional Polymerase Chain Reaction (PCR)....

Application Of Real-Time Rt-Pcr Assay For Detection And Typing Of Foot-And-Mouth Disease Virus In Tanzania

ABSTRACT Speed is paramount in the diagnosis of highly infectious Foot-and-mouth disease (FMD). Recent developments in molecular biology have enabled specific detection of FMD virus by real-time RT-qPCR and sequencing in endemic settings in Africa. In this study, a laboratory-based experimental design was used to standardize real-time RT-qPCR assay for detection and typing of FMDV in selected regions of Tanzania. The optimized conditions for both pan-serotypic and serotype-specific real-time ...

Adaptation Of Reverse Transcription Loop- Mediated Isothermal Amplification For Field Diagnosis Of Footand- Mouth Disease In Tanzania

ABSTRACT Foot-and-mouth disease (FMD) is a highly contagious viral vesicular disease of cloven hoofed animals and poses major constraints to international trade in livestock production. Methods available for detection of FMD virus (FMDV) require specialized laboratory facilities and equipment. In this study, targeted laboratorybased experiments studies were conducted using reverse transcription loop-mediated isothermal amplification (RT-LAMP) for detection and serotyping of FMDV under field ...

The Prevalence Of Methicillin-Resistant Staphylococcus Aureus (Mrsa) Isolated From Raw Bovine Milk In The Morogoro Municipality, Tanzania

ABSTRACT Methicillin-Resistant Staphylococcus aureus (MRSA) have the ability to cause superficial skin infections and occasionally causes invasive and serious diseases. This study was performed in a cross sectional design to determine the prevalence and molecular characterization of MRSA in raw bovine milk in the Morogoro Municipality. Raw milk samples (117) were collected from 18 administrative wards and cultured on Baird-Parker agar to isolate S. aureus. Presumptive colonies were analyzed ...

Genotypes Of Hepatitis B Virus Among Voluntary Blood Donors In Kinshasa, Democratic Republic Of Congo

ABSTRACT Hepatitis B represents a major global health problem. Despite the high endemicity of hepatitis B in Sub-Saharan Africa, little is known about the epidemiology and genotypes of hepatitis B virus (HBV) in Africa. The few published studies that describe the genetic characteristics of HBV in the Democratic Republic of Congo (DRC) involved a very small adult population size. In the present study, epidemiological and molecular characteristics of HBV infection were studied among voluntary b...
