RESUMO
Domestic donkey plays a key role as a draft animal in rural economy of Pakistan where its population is increasing every year. The complete mtDNA control region of forty randomly sampled donkeys was PCR- amplified and sequenced bi-directionally using specific primers. Distinct mtDNA haplotypes obtained in the current study (KY446001−KY446011) were subjected to haplotype (h) and nucleotide diversity (π) measures using DnaS as well as to phylogenetic, Network, and AMOVA analyses. There were a total 27 polymorphic sites present within 11 unique mtDNA haplotypes from the studied 40 animals from different regions. Neighbor-joining network and median-joining network both illustrated the splitting of all these haplotypes into two well-defined Nubian and Somali lineages, confirming African maternal origin of Pakistani domestic donkey. Diversity parameters h (0.967± 0.037) and π (0.02917± 0.00307) were found to reveal high levels of genetic diversity in Pakistani donkeys. AMOVA demonstrated only 1% of genetic differences between two mtDNA maternal lineages, pointing to lack of population substructure in Pakistani donkeys as is the case with worldwide domestic donkey population. Pakistani donkeys have African maternal origin and high levels of mtDNA diversity. High genetic diversity may be due to non-selective breeding and heteroplasmy. We herein provide the first report on mtDNA diversity of control region in Pakistani domestic donkey.
O burro doméstico possui um papel fundamental como animal de tração na economia rural do Paquistão, onde a população desse animal está aumentando a cada ano. A região de controle de mtDNA completa de 40 burros amostrados aleatoriamente foi ampliada por PCR e sequenciada bidirecionalmente por intermédio de primers específicos. Haplótipos distintos de mtDNA obtidos no estudo atual (KY446001 − KY446011) foram submetidos a medidas de haplótipo (h) e diversidade de nucleotídeos (π) por meio de DnaS, bem como análises filogenéticas, de rede e AMOVA. Havia um total de 27 sítios polimórficos presentes em 11 haplótipos de mtDNA exclusivos dos 40 animais estudados de diferentes regiões. A rede de união de vizinhos e a rede de união mediana ilustram a divisão de todos esses haplótipos em duas linhagens núbias e somalis bem definidas, confirmando a origem materna africana do burro doméstico do Paquistão. Os parâmetros de diversidade h (0,967 ± 0,037) e π (0,02917 ± 0,00307) revelaram altos níveis de diversidade genética em burros paquistaneses. AMOVA demonstrou apenas 1% de diferenças genéticas entre as duas linhagens maternas de mtDNA, apontando a falta de subestrutura populacional em burros paquistaneses, como é o caso da população mundial de burros domésticos. Os burros paquistaneses têm origem materna africana e altos níveis de diversidade de mtDNA. A alta diversidade genética pode ser por causa da reprodução não seletiva e de heteroplasmia. Aqui, fornecemos o primeiro relatório sobre a diversidade do mtDNA da região de controle em burros domésticos do Paquistão

The study was designed to investigate the effect of Coconut Oil on the levels of some liver and hematological parameters in carbon tetrachloride intoxicated rabbits. Also the antioxidant capacity of Coconut Oil for various concentrations was assessed on the basis of percent scavenging of (DPPH) free radical. Experimental animals were divided into five groups, eight rabbits in each group. These were: group A (Normal control), group B (Toxic control), group C (Standard control), group D (Treated with Coconut Oil 50 mL/kg body weight after CCl4 intoxication), group E (Treated with Coconut Oil 200 mL/kg body weight after CCl4 intoxication). The effects observed were compared with a standard hepatoprotective drug silymarine (50 mL/kg body weight). The Coconut Oil (200 mL/kg body weight) significantly (P<0.05) reduced the elevated serum levels of alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) when compared to a toxic control rabbits. The results of extract treated rabbits were similar to silymarine administered rabbits group. Treatment with Coconut Oil root and silymarine caused no significant changes in RBC, Platelets, (Hb), (MCH) concentration and (HCT) values. However, significant (P<0.05) increase was observed in the total WBC count. The present study suggested that Coconut Oil can be used as an herbal alternative (need further exploration i.e to detect its bioactive compound and its efficacy) for hepatoprotective activit.
O estudo foi desenhado para investigar o efeito do óleo de coco nos níveis de alguns parâmetros hepáticos e hematológicos em coelhos intoxicados com tetracloreto de carbono. Também a capacidade antioxidante do óleo de coco para várias concentrações foi avaliada com base na porcentagem de eliminação de radicais livres (DPPH). Os animais experimentais foram divididos em cinco grupos, oito coelhos em cada grupo. Estes foram: grupo A (controle normal), grupo B (controle tóxico), grupo C (controle padrão), grupo D (tratado com óleo de coco 50 mL/kg de peso corporal após intoxicação por CCl4), grupo E (tratado com óleo de coco 200 mL/kg de peso corporal após intoxicação por CCl4). Os efeitos observados foram comparados com um fármaco hepatoprotetor padrão silimarina (50 mL/kg de peso corporal). O óleo de coco (200 mL/kg de peso corporal) reduziu significativamente (P<0,05) os níveis séricos elevados de alanina transaminase (ALT), aspartato transaminase (AST) e fosfatase alcalina (ALP), quando comparado a um coelho controle tóxico. Os resultados dos coelhos tratados com extrato foram semelhantes aos do grupo de coelhos administrados com silimarina. O tratamento com raiz de óleo de coco e silimarina não causou alterações significativas nos valores de RBC, Plaquetas, (Hb), (MCH) e (HCT). No entanto, observou-se aumento significativo (P<0,05) na contagem total de leucócitos. O presente estudo sugeriu que o óleo de coco pode ser usado como uma alternativa fitoterápica (precisa de mais exploração, ou seja, para detectar seu composto bioativo e sua eficácia) para atividade hepatoprotetora.

Additional modi?cation to the Conclusion: original modi?ed Pomeroy's method of sterilization can be potentially promising in reduction of sterilization failure rate in parts of world where salpingectomy is less readily accepted
RESUMO
Abstract Plants from genus Ephedra are commonly used by the Chinese people as folk medicine for treatment of various diseases. The current study was designed to explore the ethno-pharmacological based pharmacological potentials of Ephedra intermedia Schrenk & C.A. Mey. (E. intermedia). Plant aerial parts were extracted using ten solvent systems with increasing order of polarity. Samples were analyzed for total phenolic and flavonoid contents, HPLC-DAD analysis, antibacterial, antifungal, HepG2 cell line cytotoxicity, hemolysis and antioxidant potentials following standard procedures. Highest percent extract recovery was observed in Eth+WT (25.55 % w/w) solvent system. Flavonoid and phenolic contents were higher in chloroform and Met+WT fractions respectively. Considerable antibacterial activity was shown by Eth+Met extract against B. subtilis and K. pneumonia (MIC of 11.1μg/mL for each). Eth extract exhibited high antifungal activity against A. fumigates (15±0.31 mm DIZ). Met+WT extract showed significant cytotoxicity against HepG2 cell lines with IC50 of 13.51+0.69 μg/mL. Substantial free radical scavenging activity (74.9%) was observed for Met+Eth extract. In the current study, several solvent systems were used for more effective extraction of fractions and can be useful in the isolation of phytochemicals. Various fractions exhibited considerable antimicrobial, antioxidant and cytotoxic potentials. Biological potentials of E. intermedia signify its potential uses in microbial, cancer and degenerative disorders and thus warrant further detailed studies.
RESUMO
Abstract This study was performed to screen out the various species of 'Cucurbitaceae' family, musk melon (Kalash and Durga), bottle gourd (Crystal Long and Nuefield) and squash (Green Round, and Squash Malika) against the salt stress. All genotypes were treated with five different levels of NaCl (T0 = control, T1 = 1.5 dS m-1, T2 = 3.0 dS m-1, T3 = 4.5 dS m-1 and T4 = 6.0 dS m-1) and half strength of Hoagland's nutrients solution as the base nutrient solution. Results showed that the bottle gourd varieties "Nuefield" and "Crystal Long" performed best by maintaining the highest germination (93.2% and 85.6%), number of leaves per plant (4.5 and 5.7), shoot length (16.84 cm and 16.14 cm), root length (13.48 cm and 13.00 cm), plant fresh weight (942.2 g and 918.6 g), plant dry weight (118.4 g and 107.5 g), leaf area (171.2 cm2 and 169.1 cm2), chlorophyll content (3.5 μg/cm-2 and 3.4 μg/cm-2) with low chloride (1.57 ppm and 1.59 ppm) and sodium content (0.47 ppm and 0.51 ppm) under salt stress followed by varieties of Squash (Green Round, and Squash Malika) and musk melon (Kalash and Durga). It was also found that a higher level of salinity (4.5 dS m-1 and 6.0 dS m-1) has more adverse effects on the performance of all selected genotypes. Conclusively, it can be recommended that as compared to all tested species, bottle gourd varieties "Nuefield" and "Crystal Long" have the ability to withstand against salinity stress and should be planted under salt stress conditions.
RESUMO
Aconitum heterophyllum (Patrees) is a critically endangered medicinal herb of the northwestern Himalayas and has enormous pharmacological potential. It is the only nonpoisonous member of the genus Aconitum, and has been used as a medicinal herb since ancient times. A. heterophyllum is an important ingredient in many traditional systems of medicine. Mostly, it is harvested for its roots, and its medicinal properties are due to the presence of diverse bioactive secondary metabolites, commonly known as aconites. Our understanding of the pharmacological properties of this intriguing genus is continuously growing due to its broad chemical diversity. The therapeutic uses identified by traditional medicinal practice are receiving extensive study. Multiple in vitro experimental investigations of A. heterophyllum have reported the analgesic, anti-inflammatory, antiarrhythmic, antiparasitic and anticancer properties, as well as its effects on the central nervous system. In this review, we highlight the classification, distribution, commerce, traditional uses, phytochemistry, pharmacology and conservation measures relevant to this species. Additionally, this review includes the biosynthetic pathways of A. heterophyllum's key constituents, which could be targeted to enhance the expression levels of desired metabolites via genetic interventions. Studying the genomics, transcriptomics, proteomics and metabolomic aspects of this species would be helpful in developing highly designed genotypes and chemotypes of this species to be used in commercial production.

Abstract Fish provides main source of high quality protein to more than one billion people in the world. Fish parasites directly affect the productivity of fish and indirectly on human health. This research was aimed to assess the helminth parasites in Schizothorax plagiostomus (the snow trout) from river Panjkora, KP, Pakistan. A total of 88 fish samples (n= 88) were collected from the upper, middle and lower regions of the river through cast nets, hand nets and hooks. All the collected fish samples were examined in the Parasitology Laboratory, Department of Zoology, University of Malakand for helminth parasites during July 2018 to February 2019.Among these fishes nematodes, trematodes, cestodes and acanthocephalan were isolated and identified. Overall prevalence of the fish parasites was 60.22% (53/88). The intensity of the parasite was observed from 1.7% to 4.61%. Highest prevalence was reported in summer season 86.36% while lowest in the winter season 36.36%. This study shows that summer season affects the fish business and result in poor quality fish meat with risk of zoonotic diseases. Adults were highly infected 82.25% while no infection was found in juvenile specimens. Female fish samples had higher prevalence 68.22% than males 48.22%. Fishes of the lower reaches had highest prevalence 60.22% than the upper reaches 40.0%. Fish samples with maximum length and weight were highly 76.92% infected than small sized fish with low body weight. Present study addresses that Rhabdochona schizothoracis in the intestine and Diplozoon paradoxum in gills of snow trout fish has a long term relationship and call as a natural infection in cyprinids and it is zoonotic threat to human.
Resumo O peixe é a principal fonte de proteína de alta qualidade para mais de um bilhão de pessoas no mundo. Contudo, parasitas afetam diretamente a produtividade de peixes e, indiretamente, a saúde humana. Esta pesquisa teve como objetivo avaliar os parasitas helmintos em Schizothorax plagiostomus (truta da neve) do rio Panjkora, Khyber Pakhtunkhwa, Paquistão. Foram coletadas 88 amostras de peixes (n = 88) dos trechos alto, médio e baixo do rio por meio de redes de arrasto, redes de mão e varas de pesca. Todas as amostras de peixes coletadas foram examinadas no Laboratório de Parasitologia do Departamento de Zoologia, da Universidade de Malakand, quanto a parasitas helmintos durante o período de julho de 2018 a fevereiro de 2019. Entre esses peixes, nematódeos, trematódeos, cestóideos e acantocéfalos foram isolados e identificados. A prevalência geral de parasitas de peixes foi de 60,22% (53/88). A intensidade do parasita foi observada de 1,7 a 4,61%. A maior prevalência (86,36%) foi relatada no verão, enquanto a menor (36,36%), no inverno. Este estudo mostra que a temporada de verão afeta o ramo da pesca e resulta em carne de baixa qualidade, com risco de doenças zoonóticas. Os adultos foram altamente infectados (82,25%), enquanto nenhuma infecção foi encontrada em jovens. As amostras de peixes do sexo feminino apresentaram maior prevalência (68,22%) do que as do sexo masculino (48,22%). Os peixes coletados no trecho baixo do rio tiveram maior prevalência (60,22%) do que os do trecho alto (40%). Amostras de peixes com comprimento e peso máximos foram altamente infectadas (76,92%) do que peixes de pequeno porte e baixo peso corporal. O presente estudo aborda que Rhabdochona schizothoracis no intestino e Diplozoon paradoxum em brânquias de peixes de truta da neve possuem uma estreita relação que causa uma infecção natural em ciprinídeos, sendo uma ameaça zoonótica ao ser humano.

Abstract Fish is consumed as a rich and cheaper source of white meat and proteins all over the world. Fish farming is the leading source of income generation throughout the world. The present research study was conducted with aims to investigate the ecto and endo parasitic fauna of S. plagiostomus (snow trout) in River Swat. A total of 96 fish samples were collected on monthly basis from July-2018 to February-2019, from upper, middle and lower reaches. Fish samples were collected with the help of cast net, hand net and fishing rods. Local fishermen and experts help were also sought out for fish collection. 61 out of 96 fishes were found infected by helminth parasites. The total prevalence and intensity of 63.54% and 2.90 was observed respectively during data analysis. Highest monthly prevalence of 83.33% was recorded during July and August, while lowest prevalence of 33.33% was noted during February. Five species of helminths parasites were detected from S. plagiostomus, of which two were trematodes (Rhabdochona shizothoracis and Rhabdochona species), one species of Monogenia (Diplozoon paraddoxum), one species of Cestodes (Nippotaenia species), and one species of Acanthocephalan (Neoechynorhynchus devdevi). Highest parasite wise prevalence, intensity and relative density of 21.87%, 4.09 and 0.895 was noted for R. schizothoracis while the lowest prevalence, intensity and relative density of 4.16%, 1.25 and 0.052 was noted for N. devdevi. Highest infection of 76.08% was observed in adults host while lowest, 40% infestation rate was observed in young fish samples. 73.68% prevalence was observed in female hosts while only 56.90% prevalence was observed in male individuals. Higher infection (83.33%) was noticed during summer season, while lowest infection (44.44%) was observed during winter season. Similarly 71.79% fishes were found infected that were collected from lower reaches of the River Swat than the fish samples collected from upper reaches (52%).
Resumo O peixe é consumido mundialmente por ser uma fonte rica e barata de carne branca e proteínas. A piscicultura é a principal fonte de geração de renda em todo o mundo. O presente estudo foi conduzido com o objetivo de investigar a fauna ecto e endoparasitária de S. plagiostomus (truta da neve) no rio Swat. Foram coletadas mensalmente 96 amostras de peixes, no período de julho de 2018 a fevereiro de 2019, nos trechos alto, médio e baixo com auxílio de redes de arrasto, redes de mão e varas de pesca. Pescadores locais e especialistas também ajudaram na coleta de peixes. Dos 96 peixes encontrados, 61 estavam infectados por parasitas helmintos. A prevalência de 63,54% e a intensidade total de 2,90 foram observadas durante a análise dos dados. A maior prevalência mensal de 83,33% foi registrada nos meses de julho e agosto, enquanto a menor, de 33,33%, em fevereiro. Cinco espécies de parasitas helmintos foram detectadas de S. plagiostomus, dos quais dois eram trematódeos (espécies Rhabdochona shizothoracis e Rhabdochona), uma espécie de monogenia (Diplozoon paradoxum), uma espécie de cestóideos (espécie Nippotaenia) e uma espécie de acantocéfalo (Neoechynorhynchus devdevi). As maiores prevalências de parasitas (21,87%), intensidade (4,09) e densidade relativa (0,895) foram observadas em R. schizothoracis, enquanto as menores prevalências de parasitas (4,16%), intensidade (1,25) e densidade relativa (0,052), em N. devdevi. A infecção mais alta (76,08%) foi constatada em adultos hospedeiros, ao passo que a taxa de infestação mais baixa (40%) foi encontrada em amostras de peixes jovens. A prevalência de 73,68% foi verificada em hospedeiros do sexo feminino, enquanto a de 56,90%, em indivíduos do sexo masculino. Maior infecção (83,33%) foi observada durante a temporada de verão, e a menor infecção (44,44%), durante o inverno. Da mesma forma, 71,79% dos peixes encontrados infectados foram coletados no trecho baixo do rio Swat, enquanto 52%, no trecho alto.

Abstract Helicobacter pylori is a pathogenic bacterium causing gastric problems such as, peptic ulcers and stomach cancer. H. pylori were isolated from the stomach biopsy specimens (n = 100) of gastric patients by performing polymerase chain reaction (PCR) against cagA (cytotoxin associated gene A) and ureC (Urease subunit alpha) genes. Furthermore, antibiogram studies of the H. pylori isolates were evaluated against the common antibiotics. The overall detection rate of H. pylori was 71% in biopsy specimens of gastric patients. The antimicrobial susceptibility test revealed the resistance rate of H. pylori isolates against metronidazole (50%), clarithromycin (28.33%), tetracycline (21.66%), amoxicillin (18.33%), and ciprofloxacin (11.66%). However, the H. pylori isolates were completely resistant to vancomycin, erythromycin and nalidixic acid antibiotics. Clove oil showed a remarkable antimicrobial effect against H. pylori whereas, mild inhibition (10 mm) was observed in case of curcumin extract. Due to increase incident of resistance and high prevalence of H. pylori in gastric patients, natural antimicrobial like clove oil can be explored as an alternative treatment.
RESUMO
@#Human brucellosis is a neglected zoonotic problem worldwide with a high degree of morbidity in humans and is mostly overlooked due to other febrile conditions. The aim of this study was to evaluate the sero-prevalence and risk factors of human brucellosis among subjects living in Punjab, Pakistan. In this cross-sectional study, human blood samples were collected from seven districts of Punjab, Pakistan. Information regarding personal data, demographic data and potential risk factors was collected through a structured questionnaire. Detection of anti-Brucella antibodies was done through Rose Bengal Plate Test (RBPT) and Enzyme Linked Immunosorbent Assay (ELISA). Descriptive analysis, Chi square test and Odds ratio was applied using STATA software version 12. The sero-prevalence of human brucellosis was 13.13% with significantly higher percentage in males 17.23% and age group 25-40 years 16.50% (P=< 0.001). The demographic factors positively associated with human brucellosis were lack of education (P = 0.003; OR = 1.85) and farming as an occupation (P =<0.001; OR = 2.50) Similarly, among the risk factors studied, keeping animals at home (P =<0.001; OR = 2.03), slaughtering of animals (P =<0.001; OR = 15.87) and consuming raw milk (P =<0.001; OR = 5.42) were the factors strongly connected with human brucellosis. A massive awareness should be given to livestock farmers and individuals directly linked to animals regarding risk factors and transmission of brucellosis. Consumption of unpasteurized milk and its products should be condemned to curtail this neglected disease.
RESUMO
@#Syphilis is a sexually transmitted disease and its actual prevalence among Pakistani blood donors is currently unknown. A cross sectional study was conducted at different district healthcare hospitals of Punjab, Pakistan with an aim to evaluate the prevalence and risk factors associated with syphilis in blood donors using immunochromatographic test (ICT) and enzyme linked immunosorbent assay (ELISA). A total (n=1200) blood samples were collected from donors aged 18–65 years. All the information regarding personal data, demographic data and risk factors was collected via structured questionnaire. On the basis of ICT and ELISA, the overall prevalence of syphilis was 3.91% among blood donors. The demographic factors positively linked with syphilis were age (P= 0.000; Odds ratio, OR= 7.18; 95% confidence interval CI= 2.816–18.295) and education status (P= 0.000; Odds ratio, OR= 12.33; 95% confidence interval CI= 3.469–43.849) of donors. Similarly among the risk factors analyzed, marital status (P= 0.012; Odds ratio OR= 2.251; 95% confidence interval CI= 1.206- 4.202) and blood transfusion history (P= 0.030; Odds ratio OR= 1.981; 95% confidence interval CI= 1.083-3.623) were also strongly associated with syphilis. We emphasized the importance of promoting preventive measures for syphilis. The syphilis diagnosis should not be based on a single test. The present study indicates that higher prevalence is alarming for blood donors in Pakistan. Stringent donor screening is highly recommended to ensure maximum safe blood transfusion.
RESUMO
A 40-year-old, ASA1 patient was posted for intradural extramedullary tumour at the level of L2-L3 spine. Patient was operated for the same and the tumour was resected. Postoperatively after 36 hours, patient complained of loss of bladder sensation associated with urinary retention. Surgical, urological and radiological findings were suggestive of mass effect (remnant tumour or clot) at the site of the previous surgery. A decision was taken to perform a re-exploration at the site with the use of electrophysiological monitoring including somatosensory and motor evoked potential. The surgery was performed completely under total intravenous sedation with the use of midazolam, fentanyl and propofol. The remnant mass was resected and the patient regained sensory functions in the post-operative period. Hence this case report highlights the use of total intravenous sedation for somatosensory and motor evoked potential monitoring in major neurosurgeries
RESUMO
The aim of present work was to investigate blends of Eudragit® NE 30D with Aquacoat® ECD using different ratios to eliminate curing effect associated with individual polymers. Propranolol HCl 10% w/w was layered onto sugar cores using 5% w/w HPMC as a binder. Drug-layered-cores were coated either with pure or blends of Aquacoat® ECD: Eudragit® NE 30D in a fluidized bed coater to obtain 20% w/w coating level. Talc 35% w/w was used as anti-tacking agent. The pellets were characterized for in vitro dissolution studies, morphology, water uptake-weight loss, osmolality and adhesion of coating after curing at 60 °C or 60 °C/75% RH for 24 h. The findings revealed that Aquacoat® ECD coated pellets showed curing effect due to further gradual coalescence of polymeric particles which resulted into better film formation upon curing. In contrast, the curing effect of Eudragit® NE 30D coated pellets was caused by decrease in adhesion of coatings after curing which provided entirely different swelling behavior of uncured (localized swelling) and cured (uniform swelling) pellets. The undesired curing effect of individual polymers was eliminated by using their blends in appropriate ratio.

Background: Post thoracotomy ipsilateral shoulder pain (PTISP) is a distressing and highly prevalent problem after thoracic surgery and has not received much attention despite the incidence as high as 85%. Objectives: To study the effect of phrenic nerve infiltration with Ropivacaine compared to paracetamol infusion on PTISP in thoracotomy patients with epidural analgesia as standard mode of incisional analgesia in both the groups. Study Design: Prospective Randomised and Double Blind Study. Methods: 126 adult patients were divided randomly into 2 groups, “Group A (Phrenic Nerve Infiltration Group) received 10 mL of 0.2% Ropivacaine close to the diaphragm into the periphrenic fat pad” and “Group B (Paracetamol Infusion Group) received 20mg/kg paracetamol infusion” 30 minutes prior to chest closure respectively. A blinded observer assessed the patients PTISP using the VAS score at 1, 4, 8, 12 and 24 hours (h) postoperatively. The time and number of any rescue analgesic medication were recorded. Results: PTISP was relieved significantly in Group A (25.4℅) as compared to Group B (61.9℅), with significantly higher mean duration of analgesia in Group A. The mean time for first rescue analgesia was significantly higher in Group A (11.1 ± 7.47 hours) than in Group B (7.40 ± 5.30 hours). The number of rescue analgesic required was less in Group A 1.6 ± 1.16 as compared to Group B 2.9 ± 1.37 (P value <0.5). Conclusions: Phrenic Nerve Infiltration significantly reduced the incidence and delayed the onset of PTISP as compared to paracetamol infusion and was not associated with any adverse effects.
RESUMO
Background: Timely diagnosis and treatment of tuberculosis is important to treat the disease and to reduce transmission. The WHO recommends using GeneXpert MTB in developing, high-burden countries. A study was conducted to evaluate the performance of Xpert assay for the detection of M. tuberculosis and rifampicin resistance in clinical specimen.Methods: About 615 consecutive samples were simultaneously subjected to culture and phenotypic drug susceptibility test for M. tuberculosis and analysis by GeneXpert assay. Confirmed Mycobacterium tuberculosis in a positive culture was used as a reference standard for TB diagnosis.Results: The assay achieved a sensitivity of 96.75% (268/277) and 76.47% (26/34) for smear positive and smear negative pulmonary specimen respectively. In extrapulmonary specimen, the sensitivity was 50% (1/2) and 42.8% (3/7) for smear positive and smear negative specimen respectively. An additional 48 M. tuberculosis were detected by Xpert assay which were smear and culture negative. The Xpert assay identified 100% of the phenotypic rifampicin susceptible isolates and 74.19% of the phenotypic rifampicin resistant isolates. Discordant results were seen in 8 (2.76%) isolates. 6 of these isolates were confirmed to be rifampicin resistant by the reference lab.Conclusions: Present study indicates that Xpert MTB/RIF assay is an effective and rapid tool for the rapid diagnosis of Mycobacterium tuberculosis. The sensitivity is comparable to culture in smear positive specimen but less sensitive than culture for smear negative specimen. In cases with high index of suspicion or discordance for rifampicin results, confirmation should be done by other methods due to false negative results on Xpert assay.
RESUMO
Introduction: Female genitourinary tuberculosis (FGTB) is an important cause of infertility in women of reproductive age group. The disease remains undetected due to its asymptomatic nature and lack of sensitive tests. This study was conducted with the aim of detecting the prevalence of genital tuberculosis in infertile women. Material and methods: Endometrial curetting of 193 infertile women suspected of genital tuberculosis were taken laparoscopically and sent for histopathological examination, ZN staining, culture on LJ media and GeneXpert testing. Results: Out of 193 women, 13 were positive for Mycobacterium tuberculosis making the overall prevalence of FGTB in infertile women to the extent of 6.73%. Of these 11 presented with primary infertility while 2 patients presented with secondary infertility. The histopathological examination of all the samples was non-specific. No case of positive acid fast bacilli on ZN staining was observed. Comparison of culture and GeneXpert revealed that Xpert assay was more sensitive in detecting the positive cases. Conclusion: Our study concluded that FGTB is common in our population and women presenting with infertility should be evaluated for genital tuberculosis. A high degree of suspicion and combination of histopathological and microbiological tests are important methods for the detection of genital tuberculosis
