Isolation and Identification of Coliform Bacteria and Multidrug-Resistant Escherichia coli from Water Intended for Drug Compounding in Community Pharmacies in Jordan.

(1) Background: Water is necessary for the preparation of some medicines found in pharmacies where the local water source does not meet the required purity. This study aimed to investigate the presence of coliform contamination in water used for drug reconstitution in community pharmacies in Jordan. (2) Methods: Two water samples from 50 randomly selected community pharmacies representing all Jordanian governorates were filtered and then cultured in plate count agars to determine total microbial count, and in m-Endo Agar Les and Eosin Methylene Blue (EMB) agar to cultivate Escherichia coli (E. coli). The presence of E. coli was further characterized with gram stains, biochemical tests, and Polymerase chain reaction (PCR). Antibiotic susceptibility of isolated E. coli was tested against a variety of standard antibiotics. (3) Results: Community pharmacies used droppers filled with water from coolers (62%), bottled water (20%), boiled tap water (16%) and tap water (2%). The majority of the sampled water contained coliform bacteria (88%), and E. coli was isolated from 26% of all samples. Statistical analysis showed no significant difference in the percentage of contaminated water samples based on its source location. Nonetheless, the results showed a tendency for higher proportions of contamination in droppers filled from boiled tap water (37.5%; SE: 17.1), followed by water from water coolers (25.8%; SE: 7.9), and then from bottled water (20%; SE: 12.7). All of the isolated E. coli were sensitive to gentamycin, ciprofloxacin and levofloxacin. The susceptibility of the isolates to ceftazidime, doxycycline, tetracycline, azithromycin and amoxicillin/clavulanic acid were 92%, 61%, 46%, 23% and 15%, respectively. (4) Conclusions: This study confirms the widespread presence of multidrug-resistant bacteria in water intended for reconstituting drugs in local pharmacies. These findings expose an alarming situation that needs special attention by the acting pharmacists and competent authorities. Higher levels of personal hygiene in the pharmacies coupled with regular inspection of water quality may reduce the risk of microbial contamination in compounded products, especially multidrug-resistant strains of E. coli and other index microorganisms.

Anticancer Activity Assessment and DNA Binding Properties of Two Binuclear Platinum (II) Complexes using Spectroscopic and Molecular Simulation Approaches.

BACKGROUND: Nowadays, the biological properties and anticancer activities of platinum-based drugs and metal coordination complexes have been receiving particular attention. These compounds have revealed clinical potential in cancer chemotherapy. OBJECTIVE: In this research, two binuclear platinum complexes including [Pt2Cl2(bhq)2(µ-dppm)] (1) and [(p- MeC6H4)(bhq) Pt(µ-dppm)Pt(bhq)(CF3CO2)] (2) with bhq: benzo[h] quinolone and dppm: bis(diphenylphosphino) methane have been synthesized and evaluated for their anticancer activity against A2780 and A2780/RCIS cancer cell lines. METHODS: The DNA binding and interaction of AMP/GMP nucleotide with these complexes were explored by several experimental and theoretical methods, including UV-Visible, fluorescence spectroscopic techniques and docking analysis. These complexes have demonstrated significant anticancer properties against cisplatinsensitive (A2780) and cisplatin-resistant (A2780/RCIS) human ovarian cancer cell lines. RESULTS: The obtained results indicated that these complexes interact with DNA. Additionally, the fluorescence emission measurements indicated that the platinum complexes binding with DNA structure occurs through nonintercalative interaction. The molecular docking assessments have also revealed the binding of these platinum complexes through DNA grooves. Moreover, the results have indicated that complex 1 exhibited more anticancer activity than complex 2. CONCLUSION: The results of the DNA binding with these platinum complexes confirmed their potential antitumor properties. The substitution of -C6H4CH3 and -CO2CF3 groups in complex 2 with two chlorine atoms in complex 1 acquired the significant improvement of the anticancer activity against the cancer cell.

First report of Taenia ovis infection in Danish sheep (Ovis aries).

We report Taenia ovis infection in Danish sheep for the first time. In spring 2016, the metacestode stage of T. ovis was at slaughter observed in heart muscles, diaphragm and skeletal muscles from approx. a third of all sheep from one specific farm localised in South Jutland. The diagnosis was confirmed by molecular typing of the mitochondrial cytochrome c oxidase I (cox1) gene. Three newly imported dogs were suspected but the definitive host was unidentifiable. The finding is not regulated in the meat control procedures. However, infected meat is usually condemned due to aesthetic reasons causing economic losses. Thus, finding of T. ovis is of concern to sheep meat producers in the area, as the infection could have spread further on to other farms.

The effect of educational intervention on family planning knowledge, attitudes, and practices among married women in a military barrack in northern Nigeria.

Army barracks in Nigeria have low contraceptive prevalence rates (CPRs) and many children per family. The aim of this interventional study, involving 963 married women, is to determine the impact of health education on family planning knowledge, attitudes, and practices among married barrack women. The intervention group attended a 50-minute health talk and demonstrations on family planning methods. In the intervention group, the mean knowledge score rose significantly, from 5.5 points to 7.8 points post-intervention (t = -16.7281, p = 0.0000, df = 460). In addition, the CPR increased significantly, from 11.8% at baseline to 22.4% post-intervention (McNemar's chi2 = 125.41, p = 0.0000). Such significant changes were not noted in the control group. We conclude that health education is an effective intervention for improving knowledge about and attitudes towards contraceptives and their use among married women in military barracks in Nigeria. Intense and sustained health education is therefore recommended in addressing the low CPR in Nigeria.

Infections with cardiopulmonary and intestinal helminths and sarcoptic mange in red foxes from two different localities in Denmark.

Monitoring parasitic infections in the red fox is essential for obtaining baseline knowledge on the spread of diseases of veterinary and medical importance. In this study, screening for cardiopulmonary and intestinal helminths and sarcoptic mange (Sarcoptes scabiei) was done on 118 foxes originating from two distinct localities in Denmark, (Copenhagen) greater area and southern Jutland. Fifteen parasite species were recorded in 116 foxes (98.3%), nine parasitic species are of zoonotic potential. Parasite diversity was greater in foxes of Copenhagen in terms of overall parasite species richness and species richness of all helminth groups individually: trematodes; cestodes; and nematodes. Six parasite species were recovered from foxes of Copenhagen, but not from foxes of Southern Jutland: Echinochasmus perfoliatus; Echinostoma sp.; Pseudamphistomum truncatum; Dipylidium caninum; Angiostrongylus vasorum; and Sarcoptes scabiei, but Toxascaris leonina was only recorded in foxes of southern Jutland. A high prevalence and abundance of A. vasorum in foxes of Copenhagen was observed. The prevalence of four nematode species; Eucoleus (Capillaria) aerophilus, Uncinaria stenocephala, Toxocara canis, and Crenosoma vulpis, in foxes of both localities were comparable and ranging from 22.9% to 89%. The prevalence of Mesocestoides sp. was significantly higher in foxes of Copenhagen. Taenia spp. were detected using morphological and molecular analysis, which revealed the dominance of T. polyacantha in foxes of both localities. Infections with sarcoptic mange were evident only among foxes of Copenhagen (44.9%), which significantly affected the average weight of the infected animals. Further remarks on the zoonotic and veterinary implications of the parasites recovered are given.

A coprological investigation of gastrointestinal and cardiopulmonary parasites in hunting dogs in Denmark.

A coprological survey was conducted to investigate the prevalence of parasites infecting hunting dogs with no history of recent anthelmintic treatments and with no overt clinical manifestations of cardiopulmonary or gastrointestinal illness. The hunting dogs were recruited from four different areas in Denmark, and fecal samples were obtained in October and November, 2007. For detecting gastrointestinal parasites, samples (N=178) were examined by a commercial flotation kit (Fecalyzer(®) EVSCO, USA). For detection of cardiopulmonary parasites, samples (N=181) were collected on three consecutive days and examined using the Baermann method. Parasites were recovered from 22.1% of the hunting dogs: Angiostrongylus vasorum (2.2%), Toxocara canis (12.4%), Uncinaria stenocephala (7.3%), Taenia spp. (1.7%), Toxascaris leonina (0.6%), Coccidia (0.6%) and unidentified trematode eggs (1.1%). Infection with only one species of parasite was more common (89.5%) than infection with two species (10.5%). A multiple logistic regression model showed that prevalence of intestinal parasites was not influenced by age, gender or breed in adult dogs. There was a significantly higher prevalence of intestinal parasites in the densely populated area of the island Zealand compared with the less populated regions of the peninsular Jutland. The present study reports the first case of A. vasorum in a dog from Jutland. The dog had been visiting the endemic area of western Zealand, suggesting that translocation of sub-clinically infected dogs may contribute to introduction of A. vasorum into non-endemic areas.

Multiplex PCR identification of Taenia spp. in rodents and carnivores.

The genus Taenia includes several species of veterinary and public health importance, but diagnosis of the etiological agent in definitive and intermediate hosts often relies on labor intensive and few specific morphometric criteria, especially in immature worms and underdeveloped metacestodes. In the present study, a multiplex PCR, based on five primers targeting the 18S rDNA and ITS2 sequences, produced a species-specific banding patterns for a range of Taenia spp. Species typing by the multiplex PCR was compared to morphological identification and sequencing of cox1 and/or 12S rDNA genes. As compared to sequencing, the multiplex PCR identified 31 of 32 Taenia metacestodes from rodents, whereas only 14 cysts were specifically identified by morphology. Likewise, the multiplex PCR identified 108 of 130 adult worms, while only 57 were identified to species by morphology. The tested multiplex PCR system may potentially be used for studies of Taenia spp. transmitted between rodents and carnivores.

PCR detection of Angiostrongylus vasorum in faecal samples of dogs and foxes.

The cardiovascular nematode Angiostrongylus vasorum is spreading in the fox and dog populations of northern Europe. A. vasorum can result in severe clinical manifestations in dogs; therefore, specific diagnosis is crucial for assessing its prevalence. In the present study, faecal samples from foxes and domestic dogs were tested by a new polymerase chain reaction (PCR) targeting the second internal transcribed region of the ribosomal DNA (ITS2) of A. vasorum. Initial isolation of faecal larvae by sieving facilitated the processing of larger sample volumes and allowed for the recovery of dead larvae from frozen samples. The sieve-PCR method enabled the identification of a single larva per 2 g of faecal sample and did not amplify DNA of a range of canine helminths, thus presenting a non-invasive tool for wildlife surveillance and for confirmative diagnosis in dogs.
