Study on the prevalence of co-infection between Plasmodium falciparum and Salmonella typhi among patients in Northern Nigeria was carried out. The study is cross-sectional designed to determine the socio-demographic characteristics as well as the risk factors for malaria and typhoid. A total of 100 consented patients of age group of 21-40 years were recruited for the study. A structured questionnaire was administered, and venous blood samples were collected and analyzed using standard microbiological methods. The isolated salmonella species were biochemically characterized, and subjected to antimicrobial susceptibility test using Kirby-Bauer disc diffusion method. The prevalence of malaria and typhoid was found to be 56% and 68% respectively. The prevalence of malarial parasite and Salmonella typhi infections was 40%. Females recorded low malarial infection of 56.9% compared to their male counterparts 43.1% (P= 0.510). The age group, educational levels and occupations of the study participants were not associated with the likelihood of having malarial parasite infection (P= 0.297, 0.15 and 0.503 respectively). Participants who did not sleep under the insecticide treated nets were more likely to have malaria than those who did (P ≤ 0.0001). The educational levels of the study participants were statistically associated with Salmonella typhi infection (P= 0.026). Water sources, use of pit latrine, hand washing before and after meal were significantly associated with Salmonella typhi infections (P= <0.0001 and P= 0.003 respectively). The isolates of Salmonella typhi and Salmonella paratyphi were found to be sensitive to chloramphenicol (86.8%), ciprofloxacin (80.9%) and amoxicillin (79.4%), but relatively resistant to penicillin and augmentin that recorded sensitivities of 19.1% and 35.3% respectively. The prevalence of malaria and typhoid infections as well as malarial parasite and Salmonella typhi co-infections is high among the study population. Fortunately, the isolated bacteria are highly sensitive to chloramphenicol and ciprofloxacin.

Background: The incidence of malaria is on the raise in Raichur district of Karnataka in the recent years and there is not much studies on malaria from this region. A hospital and community-based study was conducted to know the species wise incidence of malaria in pediatric age group of Raichur district and to know the efficacy of rapid diagnostic test for the diagnosis of malaria, against the gold standard ‘Microscopic examination’ of thick and thin smear.Methods: Blood samples from 676 children with clinical suspicion of malaria were tested by PBS study and RDT. Differentiation of malaria parasite is based on antigenic differences between pLDH isoforms. Results from the RDT were compared to those obtained by PBS.Results: A total of 302 (44.67%) samples were positive by PBS method of which 54 (8.0%) are Plasmodium falciparum, 248 (36.9%) are Plasmodium vivax and, while 218 (32.2%) were positive by RDT 37 (5.5%) Plasmodium falciparum, 181 (26.8%) Plasmodium vivax.  In present study the overall incidence of Plasmodium vivax in Raichur district is 36.69% and Plasmodium falciparum incidence is 7.99% and none of the samples have tested positive for Plasmodium malariae and Plasmodium ovale species among the study group.   The RDT showed sensitivities of 53.70% and 66.13% and specificities of 98.71% and 96.03%, respectively for the detection of Plasmodium falciparum and Plasmodium vivax.Conclusions: Plasmodium vivax species remains the most common malarial parasite among the positive case by PBS method in Raichur district, but the incidence of plasmodium falciparum is on the rise which is a matter of concern. The RDT method has a low sensitivity and specificity for the diagnosis of malaria since the identification of the four-parasite species is not possible. The careful examination of a well-prepared and well-stained blood film currently remains the "gold standard" for malaria diagnosis.

The investigation was performed to study the different growth stages of malarial parasite found in the peripheral blood of malaria patients of Matiranga, Khagrachhari. Rapid diagnostic test (RDT) was used to screen positive patient. The early trophozoite stages were measured 1.3 ? 1.6 μm, late trophozoites 2.5 ? 2.9 μm in diameter, microgametes 9?10 μm by 2 ? 3 μm and macrogametes 11 ? 12 μm by 2 ? 3 μm for Plasmodium falciparum. The early trophozoites 2.2 ? 3.0 μm and late trophozoites 3.3 ? 5.0 μm in diameter for Plasmodium vivax were measured. The patients of age group 1 (0 ? 10 years) were more (25%) vulnerable to the severe malaria (++++), which was 10% of the total infection, while only 10% patients of age group 2 (> 10 years) were suffering from severe form, only 0.6% of the total infection. In age group 1 (0 ? 10 yrs), + infection was 30%, ++ was 40% and +++ was 5%. In age group 2 (> 10 years), + infection was 26.66%, ++ 56.67% and +++ 6.67%, respectively.

AbstractEnteric fever (EF) is caused by Salmonella enterica serovars Typhi (S. Typhi) and Paratyphi (S. Paratyphi) causing significant health problems in developing countries including Ethiopia. Thus present study aimed to determine prevalence and antimicrobial resistance profile of S. Typhi and S. Paratyphi among EF suspected patients at Felege-Hiwot comprehensive specialized hospital, Bahir Dar, Ethiopia. Hospital based cross-sectional study was conducted from March-to-May 2020. Totally, 150 patients were included conveniently. Data were collected using questionnaires by face-to-face interview. Concurrently, venous blood and stool specimens were collected and processed following standard bacteriological technique. Antimicrobial susceptibility test (AST) was performed by disc diffusion method. Logistic regression was performed to identify factors associated with EF infection. The study indicated 5.3% EF prevalence where S. Typhi accounted 75%. S. Typhi and S. Paratyphi isolates were 100% sensitive to cephalosporins but at least 83.3% showed resistance against chloramphenicol and tetracycline. At least 66.7% of isolates were multidrug resistance (MDR). Using well water for drinking (AOR = 6.22, CI 1.4–27.5) and previous EF history (AOR = 10.74, CI 2.01–55.9) were significantly associated with EF infection. Thus high bacterial prevalence and MDR isolates was observed. Therefore, health professionals should consider AST and use antibiotics with cautions for EF patient management.

The research was aimed to evaluate the antibiotic susceptibility pattern of Staphylococcus species from clinical samples obtained from some hospitals in Kano metropolis, Nigeria. The ear swab, high vaginal swab (HVS), wound swab and urine samples from the patients attending the hospitals were collected and inoculated onto the surface of freshly prepared Nutrient agar for bacterial isolation. The bacteria isolated were identified by conventional microbiological methods namely; Gram staining, biochemical test (such as catalase, coagulase, and DNase test), mannitol salt agar and heamolysis test. The isolates were subjected to antibiotic susceptibility testing using the agar disc diffusion method. The result showed that S. aureus was highly susceptible to Ciprofloxacin 105 (68.63%), Gentamicin 102 (66.67%), Levofloxacin 95 (62.08%) and Amikacin 90 (58.82%), S. epidermidis was highly susceptible to Gentamicin 13 (61.90%), Levofloxacin 12 (57.14%) and Nitrofurantoin 11 (52.38%) while S. saprophyticus was highly susceptible to Cefoxitin 7 (77.78%), Gentamicin 6 (66.67%) and Nitrofurantoin 5 (55.56%). On the other hand, S. aureus was highly resistant to Cefuroxime 153 (100%), Ceftazidime 150 (98.04%), Amoxicillin/clavulanic acid 120 (78.43%) and Cloxacillin 111 (72.55%), S. epidermidis was highly resistant to Ceftazidime 20 (95.24%), Cloxacillin 19 (90.48%) then Cefoxitin, Erythromycin and Amoxicillin/clavulanic acid with 15 (71.43%) both. S. saprophyticus was highly resistant to Cefepime 9 (100%), Cloxacillin 8 (88.89%), Ceftazidime 7 (77.78%), Imipenem and Erythromycin with 6 (66.67%) respectively. There is a statistical difference in the sensitivity of the isolates against the antibiotics used at p<0.05. It is concluded that Staphylococcus species develop resistance to some classes of antibiotics.

Background: There has been a rapid rise in cases of COVID-19 infection and its mortality rate since the first case reported in February 2020. This led to the rampant dissemination of misinformation and rumors about the disease among the public. Objectives: To investigate the scale of public misinformation about COVID-19 in Basrah, Iraq. Methods: A cross-sectional study based on a 22-item questionnaire to assess public knowledge and understanding of information related to the COVID-19 infection. Results: A total of 483 individuals completed the questionnaire. The most frequent age group was 26–35 years (28.2%); there were 280 (58%) males and 203 (42%) females. Of the participants, 282 (58.4%) were with an education level below the Bachelor’s degree, 342 (70.8%) were married, and 311 (64%) were living in districts in Basra other than the central district. Overall, 50.8% (11.8/ 22 * 100%) of individuals had the correct information regarding COVID-19. There was a significant association between the level of COVID-19 related misinformation and participants’ educational levels and occupation (p <0.05). However, there was no significant difference found across sex, age group, marital state, and area of residence. Conclusions: Misinformation related to COVID-19 is widely spread and has to be addressed in order to control the pandemic. Keywords: COVID-19, misinformation, knowledge, Iraq

While many facets of loneliness have been explored, research examining the efficacy of loneliness interventions has been overlooked among young adults. The study of loneliness among young adults has become increasingly important considering the current state of isolation and stay-at-home orders issued to prevent the spread of COVID-19. Preliminary reports suggest an increase in loneliness as a result of the current health pandemic, especially among young adults, who have reported feeling lonelier than any other age group. Such findings warrant the study of ways to help reduce loneliness among young adults. The current study examined the efficacy of strategies that might be used to help young adults manage feelings of loneliness. Two hundred and seventy-eight young adults completed the study. Participants read one of four messages: mindfulness, social cognitions, coping behaviors, or a control. Participants in the mindfulness condition felt better equipped to manage future instances of loneliness and held better attitudes toward this intervention. The current research helps to advance understanding of effective ways of helping young adults cope with loneliness.

Bacterial infections are on a rise with causal-resistant strains increasing the economic burden to both patients and healthcare providers. Salons are recently reported as one of the sources for transmission of such resistant bacterial strains. The current study aimed at the identification of the prevalent bacteria and characterization of quaternary ammonium compound (qac) genes from disinfectant-resistant S. aureus isolated from salon tools in Ishaka town, Bushenyi District of Uganda. A total of 125 swabs were collected from different salon tools (combs, brushes, scissors, clippers, and shaving machines), and prevalent bacteria were isolated using standard microbiological methods. Identification of isolated bacteria was done using standard phenotypic methods including analytical profile index (API). Susceptibility patterns of the isolated bacteria to disinfectant were determined using the agar well diffusion method. Quaternary ammonium compound (qac) genes (qacA/B and qacC) associated with disinfectant resistances were detected from disinfectant-resistant S. aureus using multiplex polymerase chain reaction (PCR) and Sanger sequencing methods. Of the 125 swab samples collected from salons, 78 (62.4%) were contaminated with different bacteria species. Among the salon tools, clippers had the highest contamination of 20 (80.0%), while shaving machines had the lowest contamination of 11 (44.0%). The most prevalent bacteria identified were Staphylococcus epidermidis (28.1%) followed by S. aureus (26.5%). Of all the disinfectants tested, the highest resistance was shown with sodium hypochlorite 1%. Out of the eight (8) disinfectant-resistant S. aureus analysed for qac genes, 2 (25%) isolates (STP6 and STP9) were found to be qacA/B positive, while 2 (25%) isolates (STP8 and STP9) were found to be qacC gene positive. This study has shown that bacterial contamination of salon tools is common, coupled with resistance to disinfectants with sodium hypochlorite resistance being more common. Furthermore, observed resistance was attributed to the presence of qac genes among S. aureus isolates. A search for qac genes for disinfectant resistance from other bacteria species is recommended.

Abstract Introduction Globally around 47.4% of children and in India, 58% of children aged 6–59 months are anemic. Diagnosis of anemia in children using accurate technologies and providing adequate treatment is essential to reduce the burden of anemia. Point-of-care testing (POCT) devices is a potential option for estimation of hemoglobin in peripheral and field settings were the hematology analyzer and laboratory services are not available. Objectives To access the validity of the POCTs (invasive and non-invasive devices) for estimation of hemoglobin among children aged 6–59 months compared with hematology analyzer. Methods The study participants were enrolled from the pediatric outpatient department in Haryana, India, from November 2019 to January 2020. Hemoglobin levels of the study participants were estimated in Sahli’s hemoglobinometer and invasive digital hemoglobinometers (DHs) using capillary blood samples. Hemoglobin levels in non-invasive DH were assessed from the finger/toe of the children. Hemoglobin levels measured in POCTs were compared against the venous blood hemoglobin estimated in the hematology analyzer. Results A total of 120 children were enrolled. The mean (SD) of hemoglobin (g/dl) estimated in auto-analyzer was 9.4 (1.8), Sahli’s hemoglobinometer was 9.2 (1.9), invasive DH was 9.7 (1.9), and non-invasive DH was 11.9 (1.5). Sahli’s hemoglobinometer (95.5%) and invasive DH (92.2%) had high sensitivity for the diagnosis of anemia compared with non-invasive DH (24.4%). In contrast, non-invasive DH had higher specificity (96.7%) compared with invasive DH (83.3%) and Sahli’s hemoglobinometer (70%). Invasive DH took the least time (2–3 min) for estimation of hemoglobin per participant, followed by Sahli’s (4–5 min) and non-invasive DH (5–7 min). Conclusion All three POCT devices used in this study are reasonable and feasible for estimating hemoglobin in under-5 children. Invasive DHs are potential POCT devices for diagnosis of anemia among under-5 children, while Sahli’s can be considered as a possible option, where trained and skilled technicians are available. Further research and development are required in non-invasive DH to improve accuracy. Lay summary In India, anemia is a serious public health problem, where 58% of the children aged 6–59 months are anemic. Point-of-care testing (POCT) using digital hemoglobinometers (DHs) has been recommended as one of the key interventions by the Anemia Mukt Bharat program since 2018 in India. These POCT devices are easy to use, less invasive, can be carried to field, require minimal training and results are available immediately. Therefore this study assessed the validity of POCT devices—invasive DH, non-invasive DH and Sahli’s hemoglobinometer among 6–59 months children in facility setting compared with the gold standard hematology analyzer. A total of 120 children under 6–59 months of age were enrolled from the pediatric outpatient department in Haryana, India, from November 2019 to January 2020. The (mean hemoglobin in g/dl) invasive (9.7) and non-invasive DH (11.9) overestimated hemoglobin value, while Sahli’s (9.2) underestimated hemoglobin compared with hematology analyzer (9.4). Invasive DH (92.2%) and Sahli’s hemoglobinometer (95.5%) reported high ability to correctly identify those with anemia compared with non-invasive DH (24.4%). In contrast, non-invasive DH (96.73%) had higher ability to correctly identify those without the anemia compared with invasive DH (83.3%) and Sahli’s (70%).
