RESUMEN

Background: In Vietnam, cervical cancer is a significant public health concern for women. Unfortunately, despite the availability of the HPV vaccine, low vaccination rates persist. Objectives: This study investigates the discrepancy between urban and rural areas in the willingness to receive HPV vaccination with or without fees. Methods: A cross-sectional study was conducted on a sample of 648 women aged between 15 and 49, living in two urban and two rural Vietnamese districts of Can Tho, between May and December 2021. Results: The overall vaccination rate was 4%, with urban women having a higher rate of 4.9% compared to rural women at 3.1%. Among unvaccinated women, those from rural areas expressed a significantly higher desire to receive the free vaccine (91.4%) than urban women (84.4%). However, the intention to vaccinate declined when rural women and urban women were advised to pay the cost (63.4% and 57.1%, respectively). A strong correlation was found between a positive attitude and intention for vaccination, irrespective of its price or free availability. Education and access to information about the HPV vaccine were also identified as the most significant factors influencing the intention to vaccination among urban and rural women. Conclusion: The low HPV vaccination rates among women aged 15-49 living in both urban and rural regions of Vietnam are a notable public health concern. These outcomes emphasize the critical need for effective programs of vaccine laterization, as an introduction to the offer of affordable and accessible HPV vaccines for women in Can Tho, Vietnam.

RESUMEN

In this work, surface-supportive MIL-88B(Fe) was explored as a pH-stimuli thin film to release ibuprofen as a model drug. We used surface plasmon resonance microscopy to study the pH-responsive behaviors of MIL-88B(Fe) film in real time. A dissociation constant of (6.10 ± 0.86) × 10-3 s-1 was measured for the MIL-88B(Fe) film in an acidic condition (pH 6.3), which is about 10 times higher than the dissociation of the same film in a neutral pH condition. MIL-88B(Fe) films are also capable of loading around 6.0 µg/cm2 of ibuprofen, which was measured using a quartz crystal microbalance (QCM). Drug release profiles were compared in both acidic and neutral pH conditions (pH 6.3 and 7.4) using a QCM cell to model the drug release in healthy body systems and those containing inflammatory tissues or cancerous tumors. It was found that the amount of drug released in acidic environments had been significantly higher compared to that in a neutral system within 55 h of testing time. The pH-sensitive chemical bond breaking between Fe3+ and the carboxylate ligands is the leading cause of drug release in acidic conditions. This work exhibits the potential of using MOF thin films as pH-triggered drug delivery systems.

RESUMEN

A multifaceted, relationally focused intervention involving group and individual pre- and postnatal counseling, print resources, and community resources encouraged 390 fathers of newborn infants in Vietnam to responsively support mothers and work with them as a parenting team. Both partners completed questionnaires prebirth and 1-, 4-, and 9-months postbirth on measures of breastfeeding support, exclusive breastfeeding duration, relationship quality, and infant development. Compared to 412 comparison group couples, intervention couples evidenced greater father support, especially in terms of helping and responsiveness to the mother's needs. This support predicted longer exclusive breastfeeding duration, improved relationship quality, and higher levels of infant development at 9 months. Sensitively working together with mothers as a coordinated team enhanced couple's relationship functioning and improved children's developmental outcomes.

RESUMEN

BACKGROUND: The BIOCHIP is a novel multiplex indirect immunofluorescence technique used in the serological diagnosis of bullous pemphigoid and pemphigus. The BIOCHIP method combines the screening of autoantibodies and target antigen-specific substrates in a single miniature incubation field. OBJECTIVE: To evaluate the diagnostic accuracy of the new immunofluorescence BIOCHIP multiplex tool in pemphigus and bullous pemphigoid. METHODS: For the validation of the BIOCHIP, sera from patients with BP (n = 38), PF (n = 8) and pemphigus vulgaris (PV) (n = 23) were used. In addition, sera from disease control patients (n = 63) and healthy volunteers (n = 39) were used. The multiplex BIOCHIP and direct immunofluorescence (DIF) were performed for all BP, PF and PV patients. Additional indirect immunofluorescence (IIF) was performed on patients with BP, and ELISA was performed on patients with pemphigus. RESULTS: The BIOCHIP mosaic showed a sensitivity of 86.8% and specificity of 85% for BP180 or BP230 being positive in BP. It demonstrated a sensitivity of 75% and specificity of 97.7% for Dsg1 in PF. The BIOCHIP was found to have a sensitivity of 60.9% and specificity of 73.6% for Dsg3 in PV. CONCLUSION: The BIOCHIP mosaic-based immunofluorescence test is potentially a simple, time and effort saving test that can aid in the diagnosis and screening of BP, PV and PF. However, there is potential for interpretation bias and a learning curve that needs to be taken into consideration.

RESUMEN

BACKGROUND: Atopic dermatitis is a systemic disorder characterized by abnormal barrier function across multiple organ sites. Causes of epidermal barrier breakdown are complex and driven by a combination of structural, genetic, environmental and immunological factors. In addition, alteration in microflora diversity can influence disease severity, duration, and response to treatment. Clinically, atopic dermatitis can progress from skin disease to food allergy, allergic rhinitis, and later asthma, a phenomenon commonly known as the atopic march. The mechanism by which atopic dermatitis progresses towards gastrointestinal or airway disease remains to be elucidated. OBJECTIVES: This review addresses how epithelial dysfunction linking microbiome alteration and immune dysregulation can predispose to the development of the atopic march. METHODS: A literature search was conducted using the PubMed database for relevant articles with the keywords 'atopic dermatitis', 'epithelial barrier', 'skin', 'gut', 'lung', 'microbiome' and 'immune dysregulation'. RESULTS: Initial disruption in the skin epidermal barrier permits allergen sensitization and colonization by pathogens. This induces a T helper 2 inflammatory response and a thymic stromal lymphopoietin-mediated pathway that further promotes barrier breakdown at distant sites, including the intestinal and respiratory tract. CONCLUSIONS: As there are no immediate cures for food allergy or asthma, early intervention aimed at protecting the skin barrier and effective control of local and systemic inflammation may improve long-term outcomes and reduce allergen sensitization in the airway and gut.

RESUMEN

BACKGROUND: Preclinical evidence suggests that general anesthetics can dose dependently induce neurodegeneration in the developing brains of animals which can be reliably determined by measurement of blood S100ß, but this correlation remains unclear in humans. We hypothesized that S100ß would not be increased in cord arterial blood of fetuses exposed briefly to general anesthetics during a C-section, compared with epidural anesthesia. METHODS: A prospective observational clinical study comparatively measured changes of brain damage biomarker S100ß ratio of umbilical artery over vein (changes after fetus circulation) immediately after delivery under C-section with either epidural or general anesthesia. Newborn blood gas measurements, APGAR scores, and maternal well-being were also compared. RESULTS: Compared with epidural anesthesia, general anesthesia resulted in the lower S100ß ratio of umbilical artery over the vein (medium 2.64 [quartiles 1.39, 3.45] vs. medium 1.59 [quartiles 0.88, 2.01], P = 0.031), without changing the S100ß level in the vein of the mother. There was no significant difference between general and epidural anesthesia when comparing other maternal and newborn parameters. CONCLUSION: S100ß levels in newborn after C-section is lower with general anesthesia than epidural anesthesia, with unclear mechanisms.

RESUMEN

BACKGROUND: Poor antiretroviral therapy (ART) adherence leads to drug resistance and treatment failures. The options for second and third line ART regimens, particularly for pediatric patients, are very limited in low and middle-income countries. HIV-infected children are mostly passive drug-takers, thus caretakers play a very important role in assuring ART adherence. Pediatric ART adherence is still a challenging problem in Vietnam since non-adherence is the major risk factor for treatment failure. Our study explores and measures caretakers' barriers in order to improve pediatric ART adherence in future. METHODS: Exploring caretakers' barriers was conducted through a qualitative study with Focus Group Discussion (FGD) on two topics: 1. Current society - family support and difficulties in taking care children under ART; 2. Stigma experience. Based on the finding from the qualitative study a quantitative study measuring caretakers' barriers was conducted through a designed questionnaire. Study methods strictly followed the consolidated criteria with 32-item checklist for interviews and focus groups. RESULTS: In total eight FGDs with 53 participants were conducted. Common caretakers' barriers to children's ART adherence, were financial burden, lack of ART KP (Knowledge-Practice), stigma, depression, shifting caretaker, drug taste and side effects, lack of family support, fixed health check-up schedule and HIV non-disclosure. In the questionnaire study a total of 209 caretakers participated. The most commonly reported caretakers' barriers were: financial burden (144; 69%), KP burden (143; 68%), depression (85; 41%) and stigma (30; 14.8%). Some caretakers' characteristics that significantly associated with reported barriers (p<0.05). Rural caretakers reported significantly more financial burden (OR=2.26) and stigma (OR=3.53) than urban. Caretakers with under high school level education reported significantly more financial burdens (OR=2.08) and stigma (OR=4.15) compared to caretakers with high school education or over. CONCLUSION: Financial burden, KP burden, depression and stigma were common reported caretakers' barriers to pediatric ART adherence. Family residence, caretaker's education level and job were considered as the key factors determining caretakers' barriers related to financial burden and stigma. These findings may be important for policy makers and researchers in order to develop effective interventions regarding to caretakers' burdens and associated factors. Furthermore, a tool for nurses in monitoring caretakers' barriers to pediatric ART adherence was developed first with FDG, and then interview questionnaire. This tool could be applied and modified easily in any pediatric ART clinic settings in accordance to economic, social and cultural circumstances.

RESUMEN

Value-based care, which balances high-quality care with the most efficient use of resources, has been considered the next frontier in cancer care and a means to maintain health system sustainability. Created to promote value-based care, Choosing Wisely Canada-modelled after Choosing Wisely in the United States-is a national clinician-driven campaign to identify unnecessary or harmful services that are frequently used in Canada. As part of the campaign, national medical societies have developed recommendations for tests and treatments that clinicians and patients should question. Here, we present baseline indicator findings about current practice patterns associated with 7 cancer-related recommendations from Choosing Wisely Canada and about the effects of those practices on patients and the health care system. Indicator findings point to substantial variations in cancer system performance between Canadian jurisdictions, most notably for breast cancer screening practices, treatment practices for men with low-risk localized prostate cancer, and radiation therapy practices for early-stage breast cancer and bone metastases. Extrapolating indicator findings to the entire country, it was estimated that 740,000 breast and cervical cancer screening tests were performed outside of the recommended age ranges, and within 1 year of diagnosis, 17,000 patients received treatments that could be low-value. A 15% reduction in the use of the 7 screening and treatment practices examined could lead to multiple benefits for patients and the health care system: 9000 false-positive results and 3000 treatments and related side effects could be avoided, and 4500 hours of linear accelerator capacity could be freed up each year. Interjurisdictional performance variations suggest potential differences in clinical practice patterns in the planning and delivery of cancer control services, and in some cases, in disease management outcomes. Although the cancer screening and treatment practices described might be unnecessary for some patients, it is important to realize that they could, in fact, be necessary for other patients. Further research into appropriate rates of use could help to determine how much cancer care represents overuse of practices that are not supported by evidence or underuse of practices that are supported by evidence.

RESUMEN

BACKGROUND: Communication with health care providers during diagnosis and treatment planning is of special importance because it can influence a patient's emotional state, attitude, and decisions about their care. Qualitative evidence suggests that some patients experience poor communication with health care providers and have negative experiences when receiving their cancer diagnosis. Here, we use survey data from 8 provinces to present findings about the experiences of Canadian patients, specifically with respect to patient-provider communication, during the diagnosis and treatment planning phases of their cancer care. METHODS: Data from the Ambulatory Oncology Patient Satisfaction Survey, representing 17,809 survey respondents, were obtained for the study. RESULTS: Most respondents (92%) felt that their care provider told them of their cancer diagnosis in a sensitive manner. Most respondents (95%) also felt that they were provided with enough information about their planned cancer treatment. In contrast, more than half the respondents who had emotional concerns upon diagnosis (56%) were not referred to services that could help with their anxieties and fears. Also, 18% of respondents reported that they were not given the opportunity to discuss treatment options with a care provider, and 17% reported that their care providers did not consider their travel concerns while planning for treatment. CONCLUSIONS: Measuring the patient experience allows for an understanding of how well the cancer control system is addressing the physical, emotional, and practical needs of patients during diagnosis and treatment planning. Although results suggest high levels of patient satisfaction with some aspects of care, quality improvement efforts are still needed to provide person-centred care.

RESUMEN

BACKGROUND: Many prostate cancers (pcas) are indolent and, if left untreated, are unlikely to cause death or morbidity in a man's lifetime. As a result of testing for prostate-specific antigen, more such cases are being identified, leading to concerns about "overdiagnosis" and consequent overtreatment of pca. To mitigate the risks associated with overtreatment (that is, invasive therapies that might cause harm to the patient without tangible benefit), approaches such as active surveillance are now preferred for many men with low-risk localized pca (specifically, T1/2a, prostate-specific antigen ≤ 10 ng/mL, and Gleason score ≤ 6). Here, we report on patterns of care and treatment trends for men with localized low-risk pca. RESULTS: The provinces varied substantially with respect to the types of primary treatment received by men with localized low-risk pca. From 2010 to 2013, many men had no record of surgical or radiation treatment within 1 year of diagnosis-a proxy for active surveillance; the proportion ranged from 53.3% in Nova Scotia to 80.8% in New Brunswick. Among men who did receive primary treatment, the use of radical prostatectomy ranged from 12.0% in New Brunswick to 35.9% in Nova Scotia. The use of radiation therapy (external-beam radiation therapy or brachytherapy) ranged from 4.1% in Newfoundland and Labrador to 17.6% in Alberta. Treatment trends over time suggest an increase in the use of active surveillance. The proportion of men with low-risk pca and no record of surgical or radiation treatment rose to 69.9% in 2013 from 46.1% in 2010 for all provinces combined. CONCLUSIONS: The provinces varied substantially with respect to patterns of care for localized low-risk pca. Treatment trends over time suggest an increasing use of active surveillance. Those findings can further the discussion about the complex care associated with pca and identify opportunities for improvement in clinical practice.

RESUMEN

BACKGROUND: As part of Choosing Wisely Canada (a national campaign to encourage patient-provider conversations about unnecessary medical tests, treatments, and procedures), a list of ten oncology practices that could be low-value in some instances was developed. Of those practices, two were specific to radiation therapy (rt): conventional fractionation as part of breast-conserving therapy (bct) for women with early-stage breast cancer, and multifraction radiation for palliation of uncomplicated painful bone metastases. Here, we report baseline findings for the current utilization rates of those two rt practices in Canada. RESULTS: The use of conventional fractionation as part of bct varied substantially from province to province. Of women 50 years of age and older, between 8.8% (Alberta) and 36.5% (Saskatchewan) received radiation in 25 fractions (excluding boost irradiation) as part of bct. The use of hypofractionated rt (that is, 16 fractions excluding boost irradiation)-a preferred approach for many patients-was more common in all 6 reporting provinces, ranging from 43.2% in Saskatchewan to 94.7% in Prince Edward Island. The use of multifraction rt for palliation of bone metastases also varied from province to province, ranging from 40.3% in British Columbia to 69.0% in Saskatchewan. The most common number of fractions delivered to bone metastases was 1, at 50.2%; the second most common numbers were 2-5 fractions, at 41.7%. CONCLUSIONS: Understanding variation in the use of potentially low-value rt practices can help to inform future strategies to promote higher-value care, which balances high-quality care with the efficient use of limited system resources. Further work is needed to understand the factors contributing to the interprovincial variation observed and to develop benchmarks for the appropriate rate of use of these rt practices.

RESUMEN

UNLABELLED: Human respiratory syncytial virus (RSV) is the most common cause of bronchiolitis and pneumonia in infants and the elderly worldwide; however, there is no licensed RSV vaccine or effective drug treatment available. The RSV matrix (M) protein plays key roles in virus assembly and budding, but the protein interactions that govern budding of infectious virus are not known. In this study, we focus on M protein and identify a key phosphorylation site (Thr205) in M that is critical for RSV infectious virus production. Recombinant virus with a nonphosphorylatable alanine (Ala) residue at the site was markedly attenuated, whereas virus with a phosphomimetic aspartate (Asp) resulted in a nonviable virus which could only be recovered with an additional mutation in M (serine to asparagine at position 220), strongly implying that Thr205 is critical for viral infectivity. Experiments in vitro showed that mutation of Thr205 does not affect M stability or the ability to form dimers but implicate an effect on higher-order oligomer assembly. In transfected and infected cells, Asp substitution of Thr205 appeared to impair M oligomerization; typical filamentous structures still formed at the plasma membrane, but M assembly during the ensuing elongation process seemed to be impaired, resulting in shorter and more branched filaments as observed using electron microscopy (EM). Our data thus imply for the first time that M oligomerization, regulated by a negative charge at Thr205, may be critical to production of infectious RSV. IMPORTANCE: We show here for the first time that RSV M's role in virus assembly/release is strongly dependent on threonine 205 (Thr205), a consensus site for CK2, which appears to play a key regulatory role in modulating M oligomerization and association with virus filaments. Our analysis indicates that T205 mutations do not impair M dimerization or viruslike filament formation per se but rather the ability of M to assemble in ordered fashion on the viral filaments themselves. This appears to impact in turn upon the infectivity of released virus rather than on virus production or release itself. Thus, M oligomerization would appear to be a target of interest for the development of anti-RSV agents; further, the recombinant T205-substituted mutant viruses described here would appear to be the first RSV mutants affected in viral maturation to our knowledge and hence of considerable interest for vaccine approaches in the future.

RESUMEN

In this study, male fathead minnows (FHM) (Pimephales promelas) and juvenile rainbow trout (RT; Oncorhynchus mykiss) were exposed to two different surfactant mixtures of analytical-grade nonlyphenol, 4-tert octyphenol, octylphenol ethoxylates, nonylphenol ethoxylates, and the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). After a 7-days exposure to environmentally relevant concentrations of these compounds, there was no difference in the relative mRNA expression of vitellogenin (VTG) in male juvenile RT exposed to individual compounds or the 2,4-D-surfactant mixture compared with the control. In male FHM, there was a significant increase in VTG mRNA expression in the high individual treatments of 2,4-D and the surfactants but not the 2,4-D-surfactant mixtures compared with the control. These results were compared with another study exposing male FHM to individual and a mixture of alkylphenols and alkylphenol ethoxylates in two different combinations with the herbicide diuron and the insecticide bifenthrin. There were no differences in the relative expression of VTG mRNA amongst individual exposures and the control. Interestingly, when the ethoxylate mixture was combined with diuron, there was a significant decrease in the relative mRNA expression of VTG compared with the control. However, when the ethoxylate mixture was combined with both diuron and bifenthrin, there was a significant increase in the relative mRNA expression of VTG in male compared with all other groups in the multichemical mixture. The results of this study highlight differences between species and measurements of VTG in assessing the risk of mixtures to aquatic organisms.

RESUMEN

This experiment investigated effects of environmental enrichment and beak-trimming during the rearing period on behavior in rearing and plumage damage later in life. Treatments were applied in a 2 × 2 factorial arrangement. Half of the birds were beak-trimmed at 1 d of age using an infra-red laser. A follow-up light-trim was performed at 11 wk of age with a hot blade. Environmental enrichment consisted of pecking strings, whole oats in the litter, and greater litter depth. Sixteen pens of 50 ISA Brown laying hens were used. Four pullets were selected from each pen as focal birds and observed in their home pens between 3 and 14 wk of age. Plumage damage was scored at the end of the experiment in wk 43. Beak-trimmed birds performed less ground-pecking (P = 0.003), less severe feather-pecking (P = 0.021) and more gentle feather-pecking (P = 0.018) than their non-trimmed counterparts during the rearing period. These birds also exhibited less feather damage in wk 43 (P < 0.001). The results indicate that gentle feather-pecking during rearing is not related to plumage damage when older. Additionally, higher rates of ground-pecking and severe feather-pecking during rearing may be predictive of plumage damage later in life. There was no effect of enrichment on plumage damage. It was concluded that while there was no effect on enrichment, beak-trimming appeared to be effective in reducing plumage damage in wk 43.

RESUMEN

In general, guideline-recommended treatment options for men with low-risk prostate cancer (pca) include active surveillance, radical prostatectomy, and external-beam radiation therapy or brachytherapy. Because of the concern about overdiagnosis and consequent overtreatment of pca, patients with low-risk disease are increasingly being managed with active surveillance. Using data from six provincial cancer registries, we examined treatment patterns within a year of a diagnosis of localized low-risk pca, and we assessed differences by age. Of patients diagnosed in 2010 in four of the six reporting provinces, most received surgery or radiation therapy within 1 year of diagnosis. Depending on the province, either surgery or radiation therapy was the most commonly used primary treatment. In the other two provinces, most patients had no record of treatment within a year of diagnosis. Examining treatment patterns by age demonstrated a lesser likelihood of receiving surgery or radiation therapy within 1 year of diagnosis among men more than 75 years of age than among men 75 years of age or younger (no record of treatment in 69.1% and 46.3% respectively). In conclusion, we observed interprovincial and age-specific variations in the patterns of care for men with low-risk pca. The findings presented in this report are intended to identify opportunities for improvement in clinical practice that could lead to improved care and experience.

RESUMEN

BACKGROUND: Access to cancer care is a significant concern for Canadians. Prolonged delays between cancer diagnosis and treatment have been associated with anxiety, stress, and perceived powerlessness for patients and their family members. Longer wait times can also be associated with poorer prognosis, although the evidence is inconclusive. Here, we report national wait times for radiation therapy and surgery for localized prostate cancer (pca) and the effect of wait time on patient perceptions of their care. RESULTS: Treatment wait times showed substantial interprovincial variation. The longest 90th percentile wait times for radiation therapy and surgery were, respectively, 40 days and 105 days. In all provinces, waits for radiation therapy were longer for pca patients than for patients with breast, colorectal, or lung cancer. In the focus groups and interviews conducted with 47 men treated for pca, many participants did not perceive that wait times for treatment were prolonged. Those who experienced delays between diagnosis and treatment voiced issues with a lack of communication about when they would receive treatment and a lack of support or information to make an informed decision about treatment. Minimizing treatment delays was an aspect of the cancer journey that participants would like to change because of the stress it caused. CONCLUSIONS: Although wait time statistics are useful, a review of cancer control in Canada cannot be considered complete unless an effort is made to give voice to the experiences of individuals with cancer. The findings presented here are intended to provide a snapshot of national care delivery for localized pca and to identify opportunities for improvement in clinical practice.

RESUMEN

We aim to examine the miR-1288 expression in cancer cell lines and a large cohort of patients with colorectal cancer. Two colon cancer cell lines (SW480 and SW48) and one normal colonic epithelial cell line (FHC) were recruited. The miRNA expressions of miR-1288 were tested on these cell lines by using quantitative real-time polymerase chain reaction (qRT-PCR). An exogenous miR-1288 (mimic) was used to detect cell proliferation and cell cycle changes in SW480 using MTT calorimetric assay and flow cytometry, respectively. In addition, tissues from 122 patients with surgical resection of colorectum (82 adenocarcinomas, 20 adenomas, and 20 non-neoplastic tissues) were tested for miR-1288 expression by qRT-PCR. The colon cancer cell lines showed reduced expression of miR-1288 compared to normal colonic epithelial cell line. Over expression of miR-1288 in SW480 cell line showed increased cell proliferation and increased G2-M phase cells. In tissues, reduced miR-1288 expression was noted in majority of colorectal adenocarcinoma compared to colorectal adenoma and non-neoplastic tissues. Reduced or absent expression of miR-1288 was noted in 76% (n = 62/82) of the cancers. The expression levels of miR-1288 were higher in distal colorectal adenocarcinomas (P = 0.013) and in cancers of lower T staging (P = 0.033). To conclude, alternation of miR-1288 expression is important in the progression of colorectal cancer. The differential regulation of miR-1288 was found to be related to cancer location and pathological staging in colorectal cancers.

RESUMEN

In tropical regions, numerous tick-borne pathogens (TBPs) play a crucial role as causative agents of infectious diseases in humans and animals. Recently, the population of companion and pet dogs has significantly increased in Vietnam; however, information on the occurrence of TBPs is still limited. The objectives of this investigation were to determine the occurrence rate, risk factors, and phylogenetic characteristics of TBPs in dogs from northern Vietnam. Of 341 blood samples tested by PCR, the total infection of TBPs was 73.9% (252/341). Babesia vogeli (18SrRNA gene - 30.5%) was detected most frequently in studied dogs followed by Rickettsia spp. (OmpA gene - 27%), Anaplasma platys (groEL gene - 22%), Bartonella spp. (16SrRNA - 18.8%), Mycoplasma haemocanis (16SrRNA - 9.4%) and Hepatozoon canis (18SrRNA gene - 1.2%), respectively. All samples were negative for Ehrlichia canis and Anaplasma phagocytophylum. Co-infection was detected in 31.4% of the samples (107/341) of which, A. platys/Bartonella spp. (34/94,10%), Rickettsia spp./B. vogeli (19/94, 5.6%), and M. haemocanis/B. vogeli (19/94, 5.6%) were recorded as the three most frequent two species of co-infection types. Statistical analysis revealed a significant correlation between TBP infection and several host variables regarding age, breed, and living area in the current study. The recent findings reported herein, for the first time in Vietnam, are essential for local veterinarians when considering the appropriate approaches for diagnosing these diseases. Furthermore, this data can be used to establish control measures for future surveillance and prevention strategies against canine TBPs in Vietnam.
