Investigating the genetic footprints of historical temperature selection can get insights to local adaptation and feasible influences climate change on long-term population dynamics.Chicken is a significative species study account its similar domestication track related human activity with most diversified varieties. Yet, few studies have demonstrated signatures naturally tropical frigid environments.Here, we generated whole genome resequencing 119 domesticated chickens in China including...
This study provides an estimate of antimicrobial resistance in intestinal indicator bacteria from humans (n = 97) and food animals 388) Tanzania. More than 70% all fecal samples contained tetracycline (TE), sulfamethoxazole (STX), ampicillin (AMP)-resistant coliforms, while cefotaxime (CTX)-resistant coliforms were observed 40% samples. The average Log10 colony forming units/g CTX-resistant 2.20. Of 390 Escherichia coli tested, 66.4% resistant to TE, 54.9% STX, streptomycin, 36.4% CTX....
African swine fever (ASF) is an acute, highly contagious and deadly viral hemorrhagic of domestic pigs caused by virus (ASFV), a double-stranded DNA the family Asfarviridae. In this study, molecular diagnosis characterization outbreak ASFV in northern Tanzania, was performed on spleen, lymph node, kidney, heart samples collected June July 2013 from that died during disease outbreak. Confirmatory ASF using polymerase chain reaction (PCR) partial amplification B646L gene encoding major capsid...
While pathogenic types of Escherichia coli are well characterized, relatively little is known about the commensal E. flora. In current study, antimicrobial resistance in and distribution ERIC-PCR genotypes among isolates such bacteria from cattle attendants on farms Tanzania were investigated. Seventeen genomes representing different sequenced order to determine their possible importance as a reservoir for both genes virulence factors. Both human highly resistant tetracycline (40.8% 33.1%),...
This cross-sectional study was conducted between January and June 2020, in five large poultry slaughter slabs Dar es Salaam, Tanzania. Purposive sampling used to select broilers spent layers, from which meat cloaca swabs were collected determine the occurrence of multidrug resistant (MDR) Escherichia coli. Identification isolates done using API 20E, antimicrobial susceptibility testing performed as per CLSI (2018) guidelines. EBSL (CTX-M, TEM, SHV) plasmid mediated quinolone (qnrA, qnrB,...
A social strategy was tested for implementing Newcastle disease (ND) vaccination and biosecurity improvements among free-ranging chicken at village level in Tanzania. In addition to training the local poultry vaccinators, data recorders poultry-keepers, involved empowering leaders district, ward level. The trainings covered health, management, marketing of chickens, with an emphasis on ND improving against avian influenza (AI), study sites included villages one each three districts (Iringa,...
A study was conducted to assess the prevalence of parasites domestic pigeons in Morogoro Municipality, Tanzania. 100 nestlings and adult were examined for presence ecto endoparasites. 159 (79.5%) infected with one or more species gastrointestinal helminthes, 124 (62%) had ectoparasites 74 (37%) haemoparasites. The 3 subfamilies represented two cestodes nematode, whereas no trematodes found. Three helminthes Raillietina tetragona (6%), echinobothrida (63%) Ascaridia galli (15.5%) identified....
The aim of this study was to determine whether the practice co-grazing with cattle and wild life constitutes a risk transmission antibiotic resistant bacteria ungulates.Faecal samples were collected from buffalo (n = 35), wildebeest 40), zebra 40) (N 20) Mikumi National Park, Tanzania (MNP), where is prohibited Ngorongoro Conservation Area (NCA) practiced. number coliforms enterococci selected antibiotics determined. Wild generally harboured higher Escherichia coli Enterococci than cattle,...
Abstract Background Free-range local chickens (FRLC) farming is an important activity in Tanzania, however, they have not been well-characterized. This study aimed to phenotypically characterize three Tanzanian FRLCs and determine their population structure. A total of 389 mature breeder (324 females 65 males) from popular FRLC ecotypes (Kuchi, Morogoro-medium Ching’wekwe) were used for the phenotypic characterization. Progenies these utilized assess The collected four geographical zones...
Abstract Twenty flocks of web-footed birds (Pekin and Muscovy ducks geese) eight chickens raised under intensive management were examined for the presence carriers Pasteurella multocida. Five hundred seventy-eight 240 from healthy flocks, as well affected by fowl cholera, investigated. A total 135 isolates (80 55 cholera) obtained pharyngeal cloacal mucosae after mouse passage (134 isolates) culture in selective medium (one isolate). Thirty-five percent (7/20) 38% (3/8) chicken had carrying...
Newcastle disease (ND) is one of the most challenging infectious diseases affecting poultry production in Africa, causing major economic losses. To date, virus isolates from several African countries have been grouped into class II NDV genotypes I, IV, V, VI, VII, XI, XIII, XIV, XVII, XVIII and XXI. Although ND endemic many countries, information on circulating still scarce. In Tanzania, outbreaks with V XIII reported. West Central are predominant. investigate other Tanzania Ghana, we...
Newcastle Disease (ND) is a continuing global threat to domestic poultry, especially in developing countries, where severe outbreaks of velogenic ND virus (NDV) often cause major economic losses households. Local chickens are great importance rural family livelihoods through provision high-quality protein. To investigate the genetic basis host response NDV, three popular Tanzanian chicken ecotypes (regional populations) were challenged with lentogenic (vaccine) strain NDV at 28 days age....
Abstract Newcastle disease (ND) is among the most important poultry diseases worldwide. It major threat to production in Africa and causes economic losses for both local commercial chickens. To date, half of ND class II genotypes have been reported (I, IV, V, VI, VII, XI, XIII, XIV, XVII, XVIII, XXI). The information on circulating NDV still scarce despite endemic nature countries African continent.A total 659 oro-cloacal swabs were collected from chickens Mawenzi live bird market located...
Small-scale poultry production in Africa plays a significant role alleviating malnutrition and poverty rural communities. Global climate change infectious disease such as Newcastle (ND) have had tremendous negative impact on health due to limited biosecurity, cold chain, inadequate extension service. Genetic selection for enhanced resistance ND virus (NDV) offers promising complementary approach vaccination biosecurity addressing constraints village systems. The Feed the Future Innovation...
Introduction: Staphylococcus aureus is an opportunistic pathogen causing infections in humans and animals. Here we report for the first time prevalence of nasal carriage, spa typing antimicrobial resistance S. a Tanzanian livestock community. Methodology: Nasal swabs were taken from 100 humans, pigs dogs Morogoro Municipal. Each swab was enriched Mueller Hinton broth with 6.5% NaCl subcultured on chromogenic agar detection. Presumptive colonies confirmed to species level by nuc PCR analysed...
Village poultry plays a vital role in providing essential nutrition and income for rural communities Africa. In this context, are often traded through live bird markets (LBMs), which serve as central trading hubs where producers connect with traders consumers, facilitating the flow of products along value chain. While they important hubs, these create an environment avian pathogens, like Newcastle disease virus (NDV) influenza virus, can easily emerge spread. Improving our understanding...
To estimate the prevalence of antibiotic resistance in indicator bacteria Escherichia coli and Enterococci isolated from duck faeces Morogoro Municipality, Tanzania. Enterococcus isolation rates ducks were 91 100% respectively. The E. was 70.3 42%, resistant to four antibiotics 28 (30.8%) showed high ampicillin (81.3), tetracycline (75.8) trimethoprim–sulphamethoxine (62.3). Multiple more than 65%. High shown by observed rifampin (62%), (62%) (42%). Almost all farmers (92.3%) left their...
Newcastle disease virus (NDV) causes substantial economic losses to smallholder farmers in low- and middle-income countries with high levels of morbidity mortality poultry flocks. Previous investigations have suggested differing susceptibility NDV between specific inbred lines amongst breeds chickens, however, the mechanisms contributing this remain poorly understood. Studies shown that some these differences infection may be accounted for by variability innate immune response various...
