Tackling the COVID-19 pandemic: the Bangladesh perspective

An outbreak of a COVID-19 pandemic disease, caused by a novel coronavirus SARS-CoV-2, has posed a serious threat to global human health. Bangladesh has also come under the attack of this viral disease. Here, we aimed to describe the responses of Bangladesh to tackle the COVID-19, particularly on how Bangladesh is dealing with this novel viral disease with its limited resources. The first case of a COVID-19 patient was detected in Bangladesh on March 8, 2020. Since then, a total of 263,503 peoples are officially reported as COVID-19 infected with 3,471 deaths until August 11, 2020. To combat the COVID-19, the government has taken various steps viz. diagnosis of the suspected cases, quarantine of doubted people and isolation of infected patients, local or regional lockdown, closure of all government and private offices, increase public awareness and enforce social distancing, etc. Moreover, to address the socio-economic situations, the government announced several financial stimulus packages of about USD 11.90 billion. However, the government got 3 months since the disease was first reported in China, but the country failed in making proper strategies including contact tracing, introducing antibody/antigen-based rapid detection kit, and also failed to make multi-disciplinary team to combat this disease. Further, limited testing facilities and inadequate treatment service along with public unawareness are the major challenges for Bangladesh to tackle this situation effectively. Along with the government, personal awareness and assistance of non-government organizations, private organizations, researchers, doctors, industrialists, and international organizations are firmly required to mitigate this highly contagious disease

Manual on financial mechanism for the health facilities: Introducing pay-for-performance approach to increase utilization of maternal, newborn, and child health services in Bangladesh

The Population Council initiated an operations research study to test two Pay-for-Performance (P4P) strategies to improve maternal, newborn, and child health (MNCH) services in Bangladesh in 2010. The P4P study is being implemented as part of the two ongoing MNCH and maternal and newborn health (MNH) projects of the United Nations Children’s Fund (UNICEF) implemented by the Directorate General of Health Services, Government of Bangladesh. The study has been testing two strategies. The first introduces incentives tied with performance for motivating service providers to improve the quantity as well as quality of services, and enable poor pregnant women, and mothers of newborns and under-five children to access services by reducing out-of-pocket costs for medicines, transportation, and incidental costs through subsidized coupons. The second constitutes a P4P scheme for providers only. This manual, developed by the Council, describes the purposes, processes, and appropriate documents that will enable facilities and P4P and/or Coupon Committees to opportunely receive and utilize funds under the P4P and coupon mechanism to improve MNCH services

Incentivizing providers to improve maternal, newborn and child health services in Bangladesh: Pay-for-performance model refinement and advocacy (P4P MRA) final report

An operations research project by the Directorate General of Health Services (DGHS) of the Ministry of Health and Family Welfare, Government of Bangladesh tested the feasibility of a pay-for-performance (P4P) approach, which offered financial incentives to reward service providers for meeting and exceeding specified performance targets for maternal, newborn, and child health services. In response to the encouraging findings, the DGHS implemented a follow-up project, with technical assistance from Population Council and UNICEF, to utilize the experiences and findings of the P4P OR project. Despite it short duration, implementation of the revised P4P scheme induced improvements in service volume and quality of care. These projects contributed toward increasing institutional delivery, requiring less incentive cost compared to that of the DSF program, and enhancing client satisfaction by reducing out-of-pocket expenses. Despite the brief implementation period, contribution of P4P interventions in rapidly raising the level of institutional deliveries creates optimism toward meeting the MDG of reducing maternal and infant mortality

A survey of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh

Aim: To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh. Materials and Methods: The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 to June 2012. A total of 52 quail farmers were interviewed for data collection using a structured questionnaire. Focus group discussions were also carried out with unsuccessful farmers and those want to start quail farming. Workers of quail farms, quail feeds and medicine suppliers, quail eggs and meat sellers were also interviewed regarding the issue. Results: Out of 52 farms, 86.5% were operated by male, 67.3% farmers did not receive any training and 92.3% farmers had no earlier experience of quail farming although 58.0% farmers primary occupation was quail farming. Most of the farms (63.4%) were mixed in type having ≤5000 birds of two or three varieties. About 80.7% farms were operated separately round the year with no other poultry and 83.0% farmers wanted to expand their farming. The average pullet weight 14.5±0.12, 11.0±0.07, 12.0±0.22, and 12.8±0.17 g; age at the first lay 46.0±0.04, 42.0±0.31, 42.0±0.09, and 45.2±0.05 days; rearing period 15.0±0.01, 12.0±0.14, 15.0±0.32, and 15.2±0.18 months; culling period 15.5±0.14, 13.0±0.06, 15.0±0.03, and 15.4±0.26 months were for layer, parent stock, hatchery, and mixed farms, respectively. Most of the layer farms had an average egg production of ≤5000/day and net profit BDT 0.75/egg. However, an average number of birds, hatchability and net profit per day-old-chick were ≤5000, 76.8% and BDT 2.75, respectively, in the hatchery. Broiler quails were sold at 30 days with mean weight of 110.8 g and net profit BDT 9.02/bird. The major constraints of quail farming were higher feed price, outbreak of endemic diseases, lack of proper knowledge, farmers training, proper market access, difficulties of parent stock collection, inadequate biosecurity practices, and limited access to veterinary care. Thus, a proper training on quail farming, bio-security management, and government subsidy on feeds could make quail farming sustainable in Bangladesh. Conclusions: The study concludes that Japanese quail farming has enormous potentiality and could be an alternative to chicken farming particularly in providing gainful employment, supplementary income and as a valuable source of meat and egg, quail farming should be encouraged and promoted in Bangladesh

Antibiogram and virulence profiling reveals multidrug resistant Staphylococcus aureus as the predominant aetiology of subclinical mastitis in riverine buffaloes

Abstract Background Staphylococcus spp. are the major causal agents of mastitis in dairy animals worldwide leading to profound economic losses and public health threats. Recently, Staphylococcus aureus has emerged as a multidrug resistant and zoonotic pathogen. This study aimed to characterize S. aureus in subclinical mastitis (SCM) milk samples of riverine buffaloes in Bangladesh through antibiogram and virulence gene(s) profiling, and 16S rRNA gene sequencing. Method We characterized S. aureus in SCM milk samples (N = 500) of riverine buffaloes through antibiogram and virulence gene(s) profiling, and 16S rRNA gene sequencing. Results Out of 500 milk samples tested, 188 (37.6%) were found positive for SCM. From 188 SCM samples, 291 isolates were obtained with a prevalence of S. aureus in 37.4% (109/291) isolates. Phylogenetic analysis revealed the evolutionary divergence of S. aureus isolates in bubaline SCM milk samples. The antibiogram profiling showed that about 96.0% S. aureus isolates were multidrug resistant (MDR). Notably, 29 and 16 isolates harboured methicillin‐resistant (mecA) and panton‐valentine leucocidin (pvl) genes, respectively, and 46 plasmid‐bearing isolates were MDR. Nine Staphylococcal enterotoxins (SEs/SEls) including sea (11.9%), sec (7.4%), sed (4.6%), seg (3.7%), and seh (3.7%) were detected with 72.48% toxinotypes comprising a single gene. Conclusion This study therefore suggests S. aureus as the single‐most aetiology (∼37.0%) of SCM in riverine buffaloes, and emergence of MDR, enterotoxin producing, and virulent S. aureus strains could impose potential threats to animal welfare and public health

Heat stress effects on fertility and reproductive health problems of dairy cows in a selected area of Bangladesh

The impact of heat stress (HS) on reproductive performance and its problems in cows remains to be investigated in Bangladesh. The study was, therefore, aimed to evaluate the effect of HS on fertility and reproductive health problems of dairy cows in a selected area of Bangladesh. A total of 1,095 cows from 500 farms were included in this study. The climate-related data were recorded daily basis for every month in a year and temperature-humidity index (THI) values were calculated to determine the level of HS. Concurrently, data on fertility parameters [number of services per conception (NSC), conception rate (CR) and calving to the first service interval (CFSI)], and reproductive problems were collected through a pre-defined questionnaire. The results show that crossbred [Native x Holstein-Friesian, (HF)] cows were more vulnerable (p 0.05). The findings on the reproductive problems indicate that HS had significant influence on the prevalence of anestrus (χ2 = 21.814, p < 0.05) and retained placenta (χ2 = 24.632, p < 0.05) in cows. Of note, the prevalence of repeat breeding syndrome was 2.5 folds higher in stress condition than in no stress condition. Abortion and dystocia were not influenced by HS. In conclusion, HS does not influence the fertility parameters of cows studied; however, anestrus and retained placenta are likely to occur under HS conditions in cows

Bovine embryo induces an anti-inflammatory response in uterine epithelial cells and immune cells <i>in vitro</i>: possible involvement of interferon tau as an intermediator

Recent observations suggest that the bovine uterus starts to react to the early embryo immediately after its arrival from the oviduct. The present study aimed to investigate the effect of the early developing embryo on the immune-related gene profile in bovine uterine epithelial cells (BUECs) in vitro, and to further examine the impact of conditioned media (CM), either from embryo-BUEC co-culture or embryo culture alone, on gene expression in peripheral blood mononuclear cells (PBMCs). First, BUECs were co-cultured with morulae (n = 10) for D5-D9 (D0 = IVF), and gene expression in BUECs was analyzed. Subsequently, PBMCs were cultured in CM from embryo-BUEC co-culture or D5-D9 embryo culture, and gene expression was evaluated. In BUECs, the embryo induced interferon (IFN)-stimulated genes (ISGs: ISG15, OAS1, and MX2), a key factor for IFN-signaling (STAT1), and type-1 IFN receptors (IFNAR1 and IFNAR2), with suppression of NFkB2, NFkBIA and pro-inflammatory cytokines (TNFA and IL1B). The embryo also stimulated PTGES and PGE2 secretion in BUECs. In PBMCs, both CM from embryo-BUEC co-culture and embryo culture alone induced ISGs, STAT1 and TGFB1, while suppressing TNFA and IL17. Similarly, interferon tau (IFNT) at 100 pg/ml suppressed NFkB2, TNFA and IL1B in BUECs, and also stimulated TGFB1 and suppressed TNFA in PBMCs. Our findings suggest that the bovine embryo, in the first four days in the uterus (D5-D9), starts to induce an anti-inflammatory response in epithelial cells and in immune cells. IFNT is likely to act as one of the intermediators for induction of the anti-inflammatory response in the bovine uterus. c 2017 by the Society for Reproduction and Development

Zearalenone (ZEN) disrupts the anti-inflammatory response of bovine oviductal epithelial cells to sperm in vitro

Dietary contamination by Zearalenone (ZEN) has a detrimental effect on bovine fertility. Recently, we showed a novel anti-inflammatory response of bovine oviductal epithelial cells (BOEC) to active sperm cells in vitro. The aim of the present study was to investigate the effect of ZEN exposure of BOEC on the immune-related cytokine expression in response to bovine sperm. At concentrations of 100 and 1000ng/mL, ZEN induced the expression of TNF and IL1B (pro-inflammatory cytokines) as well as IL8 (chemokine) in BOEC in a dose-dependent manner. Furthermore, ZEN induced PTGES expression and PGE2 secretion in BOEC. Sperm co-culture induced an anti-inflammatory response in BOEC with upregulation of TGFB, secretion of PGE2 and downregulation of TNF. Most importantly, ZEN at 1-1000ng/mL eliminated the response of BOEC to sperm. Estradiol-17β (5ng/mL) treatment did not produce the same effects as ZEN, suggesting that the response of BOEC to ZEN is, at least in part, not mediated by estrogen receptors. Taken together, ZEN can produce inflammatory effects on BOEC by stimulating the expressions of pro-inflammatory cytokines and disrupt the normal interaction between sperm and BOEC at the level of cytokine expressions and PGE2 production. Thus, exposure of the bovine oviduct to ZEN may negatively affect sperm survival and reduce fertility
