An intrinsic membrane protein of brain synaptic vesicles with Mr 38,000 (p38, synaptophysin) has recently been partially characterized (Jahn, R., W. Schiebler, C. Ouimet, and P. Greengard, 1985, Proc. Natl. Acad. Sci. USA, 83:4137-4141; Wiedenmann, B., Franke, Cell, 41:1017-1028). We have now studied the presence p38 in a variety tissues by light electron microscopy immunocytochemistry immunochemistry. Our results indicate that, within nervous system, p38, like neuron-specific phosphoprotein...
Nerve endings of the posterior pituitary are densely populated by dense-core neurosecretory granules which storage sites for peptide neurohormones. In addition, they contain numerous clear microvesicles same size as small synaptic vesicles typical presynaptic nerve terminals. Several major proteins terminals present at high concentration in pituitary. We have now investigated subcellular localization such proteins. By immunogold electron microscopy carried out on bovine neurohypophysis we...
Houseflies (Musca domestica) are nonbiting muscoids of importance because they can be mechanical vectors many kinds pathogens such as bacteria, protozoa, viruses, and helminth eggs. This study aimed to evaluate the bacterial communities associated with houseflies captured in 3 different areas on a dairy farm located New York State. Variations community were also evaluated based flies' sex external or internal location where bacteria isolated. A total 101 flies collected: 27 from sick pen, 42...
Among more than twenty species belonging to the class Mollecutes, Mycoplasma bovis is most common cause of bovine mycoplasmosis in North America and Europe. Bovine causes significant economic loss cattle industry. The number M. positive herds recently has increased Since antibiotic treatment ineffective no efficient vaccine available, induced primarily controlled by herd management measures such as restriction moving infected animals out culling or shedders bovis. To better understand...
Non-aureus staphylococci and mammaliicocci (NASM) are the most frequently isolated bacterial group from bovine milk samples. Most studies focus on subclinical mastitis caused by NASM; however, NASM can cause clinical (CM) as well. We evaluated retrospective data 6 years (2017-2022) to determine species frequency of quarter CM. The was comprised microbiological results CM samples routinely submitted Quality Milk Production Services at Cornell University for microbial identification MALDI-TOF...
Determining the species of mycoplasma isolated from culture-positive milk samples is important for understanding clinical significance their detection. Between August 2016 and December 2019, 214,518 2,757 dairy herds were submitted to Quality Milk Production Services (QMPS) at Cornell University culture. From these samples, 3,728 collected 204 culture positive. Based on request herd managers, owners, or veterinarians, 889 isolates 98 subjected molecular identification by PCR amplicon...
Bedding materials are aimed at providing a safe and comfortable resting environment for cows. Control of pathogen proliferation in these substrates is crucial to prevent intramammary infections dairy cows, as can significantly impact milk quality, cow health, farm productivity. This particularly relevant the case organic bedding substrates, including manure-derived materials. study evaluate vitro effect lime-based conditioner (LBC), composed CaCO 3 MgCO <mml:math...
Abstract Thirty-one faecal samples were collected from red deer in the northern area of Varese, Italian region Lombardy, between August and October 2008. The animals had either been hunted or accidently killed. Examination for internal parasites showed a prevalence 45.2% Elaphostrongylus cervi larvae species identification was confirmed by polymerase chain reaction (PCR). Ninety-seven also two goat flocks grazing same December 2007 May These 74.7% lungworms. Furthermore, central nervous...
Majority of iodine found in dairy milk comes from the diet and teat disinfection products used during milking process. The objective this study was to evaluate effects 4 iodine-based dips on iodide concentrations varying level (0.25% vs. 0.5%, w/w), normal low viscosity dip versus barrier dip, application method (dip spray) ensure safe levels when these are used. exposure performed a 2-wk period. trial farm purged all for 21 d prestudy "washout period," which resulted baseline range 145 182...
The primary objective of our study was to assess the ability a vacuum recorder detect presence bimodal milk flow curves in dairy cows compared with portable meter. In cross-sectional study, 241 individual cow milking observations were analyzed. We simultaneously collected (1) events during using recorders, and (2) by attaching meter same unit. Presence bimodality assessed visually (BIMVA) gold standard method through automatic detection (BIMLA). Kappa statistics revealed moderate agreement...
Mechanical forces during machine milking of dairy cows evoke circulatory impairment the teat tissue that may affect teats' defense mechanisms against mastitis pathogens. Ample research describes dimensional changes different traits after milking, whereas reports describe in blood circulation cows' teats are limited. Therefore, objectives this study were to (1) occur pre-milking stimulation and (2) effect 2 liners on milking-induced flow. In a randomized trial, Holstein stratified by parity,...
Mycoplasma cynos is recognized as an emerging causative pathogen of canine infectious respiratory disease (CIRD) worldwide. We developed a new open-source real-time PCR (rtPCR) assay for M. that performs well under standard rtPCR conditions. Primers and probes were designed to target the tuf gene. Reaction efficiencies gene on 2 platforms based amplification curves spanning 8 orders magnitude: ABI 7500 platform, 94.3–97.9% ( r ≥ 0.9935); QuantStudio OpenArray 119.1–122.5% = 0.9784). The...
Mycoplasma mastitis can be highly contagious, unresponsive to treatment, and cause severe economic problems in affected herds. Notable routes of spp. transmissions are contaminated milking equipment animal contact through respiratory secretions. Only a few studies report the environment as possible source infection. Our group studied presence pathogens houseflies (Musca domestica) New York State dairy United States. Among others, was found gut housefly captured sick pen identified M....
